Histopathological profile of small bowel cancers in the City of Kinshasa, Democratic Republic of the Congo, from March 2011 to March 2023

Contexte et objectifs. Le cancer de l'intestin grêle est très peu documenté. L'objectif du présent travail était de décrire le profil épidémiologique et histopathologique des cancers de l'intestin grêle dans la ville de Kinshasa. Méthodes. C'était une étude descriptive d'une série des cas colligés dans quatre laboratoires d'Anatomie Pathologique de la ville de Kinshasa et sur une période de 12 ans. Les patients ayant comme diagnostic histologique des cancers de l'intestin grêle ont été répertoriés de manière exhaustive à partir des registres des laboratoires sélectionnés. Les pièces biopsiques archivées ont été relues. Résultats. Sur 812 cancers digestifs enregistrés durant la période d'étude, 43 avaient le cancer de l'intestin grêle soit une fréquence relative de 3,5 ℅. Le sexe masculin prépondérant (58,1 ℅). Les ¾ de nos patients avaient un âge compris entre 6 ans et 58 ans. Les patients plus âgés avaient un grade histologique plus élevé. La quasi-totalité de cancers de l'intestin grêle était déjà invasifs au moment du diagnostic et l'adenocarcinome était le cancer le plus fréquent. Le type histologique influençait significativement le grade (p= 0.007). Conclusion. Le cancer de l'intestin grêle dont le type le plus courant est l'adenocarcinome était invasif et rendant ainsi le pronostic plus défavorable. Ceci montre qu'il y a un problème de retard diagnostic. L'âge et le type histologique exerçaient une influence sur le niveau d'invasion des cancers de l'intestin grêle

Context and objective. Cancer of the small intestine is poorly documented. The aim of this study was to describe the histopathological profile of small bowel cancers in the City of Kinshasa. Methods.This was a descriptive study of a series of cases collected in four Pathological Anatomy laboratories in the city of Kinshasa over a 12-year period. Records of patients with histological diagnoses of small bowel cancers were exhaustively collected from the registries of the selected laboratories. Results Out of 812 digestive tract cancers recorded in studied period, 43 had cancers of the small intestine, with a relative frequency of 3.5 ℅. Male gender predominated (58.1 ℅). The ¾ of patients with small bowel cancers were between 6 and 58 years old. Older patients had a higher histological grade. Histological type had a significant influence on cancer grade (p= 0.0072). Conclusion. Almost all small bowel cancers were diagnosed at the invasion's stage, making the prognosis poorer. The high number of invasive cancers suggests that the delayed diagnosis of cancers could be the culprit in Kinshasa

Relationship between age and the histopathological features to chemotherapy response in colorectal cancer patients: a prospective observational study

Introduction: Chemotherapy response in early age-onset colorectal cancer patients is still controversial, and the results of chemotherapy response are unknown. Therefore, the purpose of this study is to determine the relationship between the age of colorectal cancer patients and histopathological features and chemotherapy response. Methods: This is a prospective observational study. The subjects in this study were colorectal cancer patients in the Digestive Surgery division at Tertiary Hospital in West Java from September 2021 to September 2022. Results: There were 86 subjects who underwent chemotherapy in accordance with the inclusion and exclusion criteria. Consisting of 39 patients of early age onset and 44 female patients. The most common histopathological feature in early age onset (EAO) and late age onset (LAO) was adenocarcinoma (25% and 46%, respectively). Stage III colorectal cancer affected 38 patients, while stage IV affected 48 patients. There was a significant relationship between early age onset and late age onset with histological features (p < 0.001). The patients with the highest chemotherapy response had stable diseases in EAO (17 patients) and LAO (20 patients). There was no statistically significant relationship between age, histological features, and stage of colorectal cancer and chemotherapy response (p > 0.05). The results of the ordinal logistic regression test showed no systematic relationship between chemotherapy response and age, histopathological features, gender, or cancer stage (p > 0.05). Conclusion: There was no association between age and histopathologic features with chemotherapy response and there is no difference in chemotherapy response between early and late age onset. (AU)

High frequency of larval abnormalities of the toad Rhinella arenarum (Anura: Bufonidae) in an Argentinian agroecosystem

Introduction: The frequent use of pesticides is currently considered a cause of environmental pollution due to the high rate of entry of these substances into agroecosystems. This constitutes a risk for the species that inhabit these ecosystems, in particular anurans whose characteristics make them prone to exposure to and interaction with environmental pollutants. Objective: To report the occurrence of abnormalities in larvae of the common toad Rhinella arenarum inhabiting ponds surrounded by agroecosystems. Methods: In two consecutive springs (2015 and 2016), reproductive events of common toads were monitored in temporary pond systems in agricultural and non-agricultural areas, located near the city of La Plata (Buenos Aires, Argentina). The physicochemical parameters of the ponds were measured, and the stage of each reproductive event was recorded, such as the numbers of adult toads, amplexus and clutches. In the laboratory, the larvae were measured and photographed, their stage of development was recorded, and their morphology was examined under a stereomicroscope. Representative samples (normal and abnormal) from each pond studied were processed for histopathological analysis. Results: In the field studies carried out on a population of R. arenarum collected in an agroecosystem, a lower number of reproductive adults and clutches were observed in relation to the population of a non-agricultural pond. A total of 1 910 larvae were collected: 529 and 1 381 larvae from ponds located in non-agricultural and agricultural areas, respectively. Larvae from the agroecosystem showed two types of abnormalities: severe tail flexure and abdominal bloating. In addition, five degrees of severity could be determined in relation to abdominal bloating. Conclusions: This work reports the high frequency and severity of abnormalities observed in the early stages of R. arenarum larvae living within an agroecosystem, providing evidence of the negative impact that agricultural activities cause on aquatic ecosystems surrounded by farming areas.

Introducción: El uso frecuente de plaguicidas es considerado actualmente una causa de contaminación ambiental debido a las altas tasas de ingreso de estas sustancias a los agroecosistemas. Esta situación es un riesgo para las especies que habitan en estos ecosistemas, en particular los anuros cuyas características los hacen propensos a la exposición e interacción con contaminantes ambientales. Objetivo: Informar la presencia de anormalidades en larvas del sapo común Rhinella arenarum que habitan en estanques rodeados por un agroecosistema. Métodos: En dos primaveras consecutivas (2015 y 2016), se monitorearon los eventos reproductivos del sapo común proveniente de sistemas de estanques temporales ubicados en zonas agrícolas y no agrícolas, cerca de la ciudad de La Plata (Buenos Aires, Argentina). Se midieron los parámetros fisicoquímicos de los estanques y se registraron las etapas de cada evento reproductivo como el número de sapos adultos, amplexos y nidadas. En el laboratorio, las larvas fueron medidas y fotografiadas, se registró su estado de desarrollo y se examinó la morfología de cada una bajo microscopio estereoscópico. Se procesaron muestras representativas (normales y anormales) de cada estanque estudiado para análisis histopatológico. Resultados: En la población de R. arenarum que vive dentro de un agroecosistema, se observó un menor número de adultos reproductores y puestas en relación con la del estanque en la zona no agrícola. Se recolectaron un total de 1 910 larvas: 529 y 1 381 larvas de estanques ubicados en zonas no agrícolas y agrícolas, respectivamente. Las larvas del agroecosistema mostraron dos tipos de anormalidades: severa flexión de la cola y distensión abdominal. Además, se pudo determinar cinco grados de gravedad en relación con la distensión abdominal. Conclusiones: Una alta frecuencia y severidad de anormalidades en los estadios tempranos de larvas de R. arenarum que viven dentro de un agroecosistema proporciona evidencia del impacto negativo que las actividades agrícolas causan en los ecosistemas acuáticos rodeados por áreas de cultivo.

Oral Submucous Fibrosis: Clinical Stage, Functional Stage, and Histopathological Grade Correlation

Background- Oral submucosal fibrosis (OSMF) is a common precancerous condition predominantly affecting the oral cavity. There are several contributing factors to its pathogenesis, areca nut chewing being the primary culprit. OSMF reversal is difficult once the disease sets in. Hence, after its diagnosis, staging becomes imperative as it affects the treatment plan. Several classification methods have been developed by various authors to categorize the disease based on its clinical, functional, and Histopathological characteristics. The main aim to conduct this study was to correlate clinical and histopathological staging. Materials & Methods- This study involved 30 patients who had been diagnosed with OSMF both Clinically and Histopathologically. All 30 patients were classified and were categorized according to their clinical and functional stages after inspection. Following this, histopathological grading was done. Results- The statistical analysis showed that there was a wide similarity between the clinical and functional staging. However, no significant similarity or correlation was found between the clinical and functional staging with its corresponding histopathological grades. Conclusions- Our study concluded that there is strong correlation between clinical and functional grading.

Clarified Butter as Xylene Substitute in Routine Histopathology of Oral and Maxillofacial Biopsies

Introduction: An ideal clearing agent should remove alcohol from the tissue specimens to enable the penetration of paraffin wax which provides sturdiness to the tissue specimen. Xylene has toxic effects and is still used because of its accurate clearing property and maintaining the staining quality. Natural alternatives to xylene provide a less toxic environment for histopathological technicians. Aim: The study is to evaluate the accuracy of clarified butter as xylene substitute in routine histopathological tissue processing procedure. Materials and Methods: 40 paired soft tissue specimens were obtained from the Department of Oral pathology and microbiology and subjected to routine histopathological tissue processing with xylene and ghee as clearing agents. Post processing, the tissue specimens were immersed in paraffin wax overnight, embedded, sectioned and stained using hematoxylin and eosin. Histopathological criteria namely nuclear staining, cytoplasmic staining, artefacts and background staining were evaluated and the scores were tabulated and statistical analysis was done using SPSS version 20 by IBM. Results: Our study results showed that tissue specimens processed in xylene and ghee had similar nuclear staining. In cytoplasmic staining, tissue specimens processed in ghee had superior results than xylene processing. Artefacts were present more in xylene processing than ghee processing. Background staining was more appreciated in xylene processed tissue specimens than ghee processing. Conclusion: Substituting xylene with ghee showed better results as a clearing agent in routine histopathological tissue processing. Ghee as a clearing agent is non toxic, cost effective compared to xylene and a safer alternative.

Clinicopathological correlation of various prostatic lesions with serum prostate-specific antigen level – A hospital-based cross-sectional study

Background: The prostate is a male reproductive accessory gland which gives rise to several pathological conditions. The present study aims to study the correlation of histopathology of prostatic diseases with the clinical profile of the patient coming to VSS Medical College (VSSMC), Burla for histopathological reporting of prostatic biopsies. Aim and Objectives: The objectives of this study were as follows: (1) To correlate serum prostate-specific antigen (PSA) level with various clinical and pathological lesions of the prostrate gland, in a Hospital-based sample of Western Odisha population. (2) As the male gender represents almost half of the entire population, to find out different clinicopathological lesions, percentage-wise, so as to know the frequency of occurrence of such lesions. Materials and Methods: Fifty-seven cases of prostatic diseases were recorded in the Department of Pathology, VSSMC, Burla for histopathological examination of prostatic tissue for 2 years from September 2017 to August 2019. All the samples were fixed in 5 ? sections with 10% neutral buffered formalin. Then Hematoxylin and Eosin stain (H and E stain) was used for staining. Appropriate clinical data comprising signs and symptoms, laboratory findings, and serum PSA levels were recorded. Results: The present study, in the beginning, consisted of 64 patients, out of which seven patients were excluded by exclusion criteria, and finally, 57 cases were analyzed. The most prevalent age group for all prostatic diseases was 61–70 years with a mean of 67 years. The majority of the cases (73.67%) were benign mostly benign prostatic hyperplasia (BPH). Prostatic intraepithelial neoplasia (PIN) was 12.29% and malignant cases (all adenocarcinoma) were also 12.29%. All patients showed prostatomegaly. About 50% of cases suggestive of malignancy by digital rectal examination (DRE) were confirmed to be carcinoma by histopathological study. Serum creatinine level was raised in 16.27% of benign and 21.42% of premalignant and malignant conditions. Serum PSA level below 4 ng/mL were all benign and above 10 ng/mL were majority malignant conditions. However, at level 4–10 ng/mL, BPH and PIN cases were overlapped with cases of carcinoma. Conclusion: Benign prostatic hyperplasia is the most commonly encountered prostatic lesion. Serum PSA level <4 ng/mL is associated with benign conditions and more than 10 ng/mL is associated more with carcinomas. Although, investigations such as DRE and serum PSA estimation aid in diagnosis, a definitive diagnosis of benign and malignant lesions of prostate can be made by histopathological study of prostatic biopsies.

Schwannoma in the nasal cavity: A benign nerve sheath tumor at an odd location

Schwannomas are neurogenic tumors arising from the Schwann cells present in the neural sheath of the myelinated nerves. These are benign tumors that can arise anywhere in the body. Schwannomas are rarely seen in the nose and paranasal sinuses representing <4% of all head-and-neck schwannomas. Surgical excision is the treatment of choice in these cases. Nasal polyps are common nasal cavity lesions which are usually inflammatory polyps. Schwannoma of the nasal cavity usually presented with headache, unilateral nasal obstruction due to mass obliterating the nasal cavity, and epistaxis. Here, we report the case of a 47-year-old female who presented with a mass in the left nasal cavity causing the nasal blockage.

Histopathological Profile of Obese Zebrafish Liver after Administration of Red Spinach (Amaranthus tricolor L.)

Aims: Obesity is a non-communicable disease whose prevalence continues to increase every year throughout the world. Obesity contributes to the emergence of several diseases such as type-2 diabetes mellitus, hypertension, cardiovascular disorders, cancer, and non-alcoholic fatty liver. A number of studies report that natural ingredients have the potential to be used as a treatment for obesity while reducing a fatty liver. The aim of this research is to evaluate the activity of red spinach ethanol extract in reducing the accumulation of fatty liver in diet-induced obese zebrafish based on its histopathological profile. Methodology: Zebrafish must be adapted for 2 weeks. After 2 weeks, the zebrafish were divided into 6 groups which included: the normal group (or negative control); the obesity group (positive control group); the standard drug (orlistat with dose 4.5 µg/ml); the EERS group (dose of 50 µg/ml); the EERS group (dose of 100 µg/ml); and the EERS group (dose of 200 µg/ml). For a period of 4 weeks, the normal group received a standard diet. A positive control group received Artemia. The treated group received Artemia which was combined with the administration of red spinach (preventive method). The obese group and extract-treated group were given 60 mg/group/fish in the experimental diet. Results: The results showed that EERS at a dose of 100 µg/ml did not show any fatty liver based on their histopathological profile. The EERS dose of 200 µg/ml is more effective in reducing fatty liver when compared to doses of 50 µg/ml and 100 µg/ml on obese zebrafish. Conclusion: Based on the results of the study, it can be concluded that EERS is very prospective for further research and development as a drug for treating obesity and reducing fatty liver.

HISTOMORPHOLOGICAL EVALUATION OF LESIONS IN NEPHRECTOMY SPECIMENS

Nephrectomy, histopathological examination, neoplastic, renal cell carcinomaBackground: Nephrectomy either partial or radical has become a common procedure in surgical and urological practice. In this study pathological reports were interpreted for the following parameters: age, gender, pathological diagnosis. An indication of nephrectomy depends on type of lesion, extent of damage, general condition of patient and status of contralateral kidney. Method: The present ambiceptive data analysis has been carried out in Department of Pathology in tertiary care centre under Maharashtra University of Health Sciences by histopathological examination of nephrectomy specimens. A Results: total of 59 nephrectomy cases were included in the study. Non neoplastic and neoplastic cases were 44 (75%) and 15 (25%) respectively. Among non-neoplastic lesions, total of 32 cases (72%) were diagnosed as Chronic pyelonephritis with End Stage Renal Disease(ESRD) . Others Chronic Xanthogranulomatous Pyelonephritis with ESRD 9 cases (21%) and Chronic Glomerulonephritis with ESRD 3 cases (7%). Neoplastic lesions constitutes 15 cases with peak in 6th decade. Renal Cell Carcinoma(RCC) is the most common neoplastic lesion. The distribution among the neoplastic lesions include: Clear cell RCC (40%), Papillary RCC (13.34%), Mixed RCC (13.34%), Chromophobe RCC (13.34%), Multicystic nephroma (6.67%), Collecting duct carcinoma (6.67%) and Renal Medullary carcinoma (6.67%). Fuhrman's nuclear grade II is the most common among the RCC. Rare case such as Collecting Duct carcinoma, Renal Medullary carcinoma and Sarcomatoid RCC were diagnosed during the study period. On IHC, Collecting Duct carcinoma is positive for HMW CK, PAX8 and Renal medullary carcinoma is positive for Vimentin. The histopathological Conclusion: examination is essential to differentiate between benign and malignant neoplastic lesions and in grading of malignant lesions which help in treatment and further management of patients.

HISTOPATHOLOGY OF GALLBLADDER SPECIMENS AFTER CHOLECYSTECTOMY: A RETROSPECTIVE STUDY

Background Current approach to detect the presence of gallbladder carcinoma involves a routine histopathological examination of all gallbladder specimens, regardless of the clinical characteristics of the patient or macroscopic aspect of the gallbladder. Available pathological reports were interpreted for the following parameters: age, gender, and pathological diagnosis. In addition, the demographic information and clinicopathologic characteristics of the patients with histopathologic findings were assessed in detail, and re-examination of the available specimens was done. Inpatient records of the Methods patients who had been operated for elective and emergency cholecystectomies in the hospital associated with Khaja Bandanawaz University – Faculty of medical Sciences; from January 2018 to November 2022, were retrospectively evaluated. Results A total of 661 gallbladder specimens submitted for histopathological examination during the study period were included in the study. The results of histopathological examination of these gallbladder specimens showed that chronic cholecystitis was found in 535 (81%), acute cholecystitis in 46 (6.99%), cholesterolosis in 44 (6.5%) patients, Dysplasia was found in 34 (5.14%) patients, and gallbladder carcinoma was detected in 2 (0.30%) patients. Conclusion A strategy of selective approach for histopathological examination of gallbladder specimens may be safe in areas with very low incidence of gallbladder carcinoma. Such selective strategy is more cost-effective, reduces the workload of pathologists, and does not appear to compromise patient outcome.

Analysis of clinical and pathological features of 54 adult inpatients with erythema nodosum / 中华皮肤科杂志

Objective:To investigate clinical and histopathological features of adult erythema nodosum (EN) .Methods:Clinical data were collected from 54 adult inpatients with histopathologically confirmed EN in Department of Dermatology and Venereology, the First Affiliated Hospital of Wannan Medical College from November 2019 to July 2022, and analyzed retrospectively.Results:Among the 54 EN patients, there were 6 males and 48 females, their ages were 42.50 ± 11.68 years (range, 18 - 73 years), and their disease course ranged from 1 day to 10 years; 30 patients (55.56%) were diagnosed with idiopathic EN, and 24 (44.44%) with secondary EN. The most common etiological factor in secondary EN was infection (17 cases), including respiratory tract infection (9 cases), tuberculosis infection (6 cases), upper respiratory tract infection comorbid with active hepatitis B virus infection (2 cases) ; the following common etiological factor was connective tissue disease (7 cases), including Behcet′s syndrome (4 cases), Sj?gren′s syndrome (1 case), and undifferentiated connective tissue diseases (2 cases). The patients′ ages were significantly younger in the secondary EN group (38.33 ± 12.15 years) than in the idiopathic EN group (46.17 ± 10.20 years, t = 2.58, P = 0.013). All patients had skin lesions on their lower limbs, lesions were limited to both lower limbs in 24 patients with idiopathic EN and 12 with secondary EN, and the proportion of patients with lesions limited to both lower limbs was significantly lower in the secondary EN group than in the idiopathic EN group ( χ2 = 5.44, P = 0.020). Compared with the idiopathic EN group, the secondary EN group showed significantly increased white blood cell counts ([7.56 ± 2.46] × 10 9/L vs. [6.04 ± 1.60] × 10 9/L, t = 2.62, P < 0.05) and C-reaction protein levels (34.34 ± 46.48 mg/L vs. 11.45 ± 18.13 mg/L, t = 2.28, P < 0.05). In the idiopathic EN group, 23 patients mainly showed histopathological features of septal panniculitis, while 17 patients in the secondary EN group mainly showed histopathological features of mixed panniculitis or lobular panniculitis, and the proportion of patients with histopathological features of mixed panniculitis or lobular panniculitis was significantly higher in the secondary EN group than in the idiopathic EN group ( χ2 = 12.18, P < 0.001) . Conclusion:EN was more common in female adults; idiopathic EN was the most common type, and secondary EN may be a cutaneous sign of systemic diseases; for EN patients at a relatively young age, with lesions involving both lower limbs or more sites, higher white blood cell counts and C-reaction protein levels, and histopathological manifestations of lobular panniculitis, systemic examinations were required to rule out underlying causes.

Analysis of clinical features of seven patients with granular parakeratosis after benzalkonium chloride exposure / 中华皮肤科杂志

Objective:To summarize clinical manifestations and histopathological features of granular parakeratosis (GP) after exposure to benzalkonium chloride.Methods:A retrospective analysis was performed on 7 GP cases with a history of benzalkonium chloride exposure in the Department of Dermatology at Wuhan No.1 Hospital from April to August 2022. Data were collected on the general condition, skin lesion manifestations, pathological examination, treatment, and follow-up of the patients, and retrospectively analyzed.Results:The 7 adult patients with GP typically presented with erythema and brown scales in the intertriginous area, exhibiting an annular distribution pattern. All the 7 patients reported recent exposure to disinfectants containing benzalkonium chloride. A total of 10 skin biopsies were taken from the 7 patients. Histopathological examination showed characteristic hyperkeratosis and fine blue-gray parakeratotic granules in the stratum corneum. All skin lesions improved 1 month after cessation of exposure to benzalkonium chloride.Conclusion:GP has a distinct clinical pattern and histopathological manifestations, and a history of exposure to benzalkonium chloride can be helpful for the diagnosis of GP.

The latest consensus and clinical application of the histopathological growth patterns of colorectal cancer liver metastasis / 中华肝胆外科杂志

The histopathological growth pattern (HGP) of colorectal cancer liver metastasis (CRLM) is correlated with the prognosis of patients. Patients with desmoplastic HGP have a better prognosis. The latest international scoring guidelines have modified the cut-off value of HGP, and divides it into two types: complete desmoplastic HGP and incomplete desmoplastic HGP. However, the relationship between the HGPs and the treatment response to systemic treatment is still unclear. It is necessary to develop non-invasive methods to evaluate changes in HGP during treatment in the future. This paper reviews the new scoring consensus and clinical applications of HGP in CRLM.

Histopathological analysis of hysterectomy specimens

Background: Uterus is prone for various non-neoplastic and neoplastic lesions and also hysterectomy is the most common gynecological surgery indicated as a definitive treatment. Grossly unremarkable many specimens may reveal pathologies on histological examination. Hence, all hysterectomy specimens must undergo proper histopathological examination. In our study, hysterectomy specimens were studied and results compared with their clinical diagnosis. Aim and Objective: The objectives of the present study were to know the frequency and incidence of various lesions of the female genital tract and to compare findings of the present study with other studies. Materials and Methods: The study was a retrospective analysis of 250 hysterectomy specimens. All types of hysterectomies such as vaginal, abdominal, laparoscopic, and total abdominal hysterectomy without or with unilateral/bilateral salpingectomy/salpingo-oophorectomy were included in the study. Histopathological examination was done minimum by two faculty members. The results were noted and statistical analysis was done. Results: Total 250 hysterectomy specimens were studied. Vaginal hysterectomy was the most commonly performed type of hysterectomy which includes 187 cases (74.8%) out of 250 cases. Among the uterine pathologies, the most common lesion was leiomyoma (34.4%) followed by adenomyosis (26%). In our study during histopathological examination of cervix, the most frequent cervical lesion was found chronic cervicitis in 50.4% of cases. Conclusion: The present study highlights the wide spectrum of lesions of female genital tract and conveys that histopathology remains the primary modality for confirmation of diagnosis of lesions. We can conclude from the present study that many lesions had been diagnosed on microscopic examination though normal gross examination. Hysterectomy specimen should undergo proper histopathological examination, because it is the gold standard tool for final diagnosis.

Modified Alvarado score versus Tzanaki’s Score in diagnosing acute appendicitis: An observational study

Background: Appendix is a blind muscular tube derived from the midgut. During the embryogenic development, in the 6th week appendix and cecum appear as out pouching from midguts caudal limb. Acute appendicitis is one the most common diagnosis made whenever patient presents with right illac fossa pain and mostly encountered in young and middle-aged individuals. The diagnosis and management of acute appendicitis depend on clinical presentation, that is, clinical signs and symptoms. The most common presentations in these cases have abdominal pain along with fever, anorexia, nausea, and vomiting. Various Scoring systems are developed to diagnose acute appendicitis based mainly on the presenting signs and symptoms, but widely none of them are used as an uniform scoring system. Aims and Objectives: The purpose of this study was to assess effectiveness and comparison of modified Alvarado score and Tzanaki’s Score in the early diagnosis of acute appendicitis. Materials and Methods: A prospective observational study was done in department of General Surgery JLN Medical College Hospital, Ajmer which included 200 patients presenting with the signs and symptoms of acute appendicitis, clinically. During admission the patients were evaluated by Modified Alvarado score and Tzanaki’s Score and final surgical decision was taken by the treating surgeon. Finally, the scores were compared with the histopathological examination of the surgically operated specimen. Results: The sensitivity and specificity of Modified Alvarado Score was 84.26% and 72.7%, respectively, with a positive predictive value of 96.15% and negative predictive value of 36.3%. The sensitivity and specificity of Tzanaki’s score was 88.2% and 72.7%, respectively, with a positive predictive value of 96.31% and negative predictive value of 43.24%. The diagnostic accuracy of Alvarado score was 83% and that of Tzanaki’s score was 86.5%. Conclusions: Our study showed that Modified Alvarado scoring system is a simple tool with limited features for bedside diagnosis of acute appendicitis, but its effectiveness is not as good as that of Tzanaki’s scoring system.

Osteolipoma of leg masquerading as osteoid osteoma: A case report

Lipomas are the most common, subcutaneous, and slow-growing tumors composed of fat (adipose tissue). Out of many types of these benign tumors, ossifying lipoma (osteolipoma) is the rarest subtype. Here, randomly distributed trabeculae of lamellar bone are seen within mature adipose tissue. They are featured only as isolated case reports and small case series, thus the true incidence is not known. The most common site for osteolipoma is the head and neck region and they are rarely reported in the lower extremities. Herein, we discuss the case of a 19-year-old man who presented with a progressively enlarging painful mass in the left leg. Radiology was typical of osteoid osteoma. Excision was performed and histopathological examination confirmed the lesion as osteolipoma with no evidence of malignancy. No recurrence of the tumor was observed after 2 years of follow-up. Although osteolipoma is a rare entity, the differential diagnosis of the lesion can be kept in mind whenever we encounter ossification within the adipose tissue.

Histopathological finding of vesiculobullous lesions of skin in relation to their clinical presentation: Prospective study from a tertiary care center

Background: Vesiculobullous disorders (VBDs) are extant with diverse clinical manifestations. Vesicles and bullae are fluid-filled cavities present within or beneath the epidermis. They are autoimmune blistering disorders in which autoantibodies are directed against target antigens present in the epidermis and dermo-epidermal junction. Objective: Evaluation of the various clinicodemographic profile of patients with a pattern of distribution (subtypes) of VBDs of the skin and assess the association between clinical aspects and histological changes in vesiculobullous lesions of the skin. Materials and Methods: The study material constituted 93 cases of VBDs out of 936 skin biopsies reported over two and a half years (January 2016 to June 2018) from the tertiary care center. A detailed history of the patients was taken, and a complete physical and dermatological examination with findings including clinical diagnosis was recorded. Histopathological examination (incisional/excisional/punch biopsy) was done in each case. The clinico-demographic evaluation was done and the results were correlated with histopathological findings. Results: Vesiculobullous lesions constituted 10.06% of all skin biopsies. The majority of cases were of pemphigus vulgaris (PV) 30 (32.25%) followed by 16 (17.2%) of bullous pemphigoid. In 83 cases (89.24%) histopathology findings were consistent with clinical diagnosis. Out of 34 cases that were diagnosed clinically as PV , the histopathological study proved 30 cases (88.23%) as PV. Conclusion: Vesiculobullous lesions of the skin are a heterogeneous group of disorders. It is essential to differentiate each pattern of subtype based on clinical examination and histopathological findings. Histopathological diagnosis with clinical correlation plays a major role in arriving at the diagnosis.

A STUDY OF THE CLINICAL, RADIOLOGICAL, CYTOLOGICAL AND HISTOPATHOLOGICAL CORRELATION OF SOLITARY THYROID NODULE

Background: Solitary thyroid lesions are a common presentation in the surgical OPD. The signi?cance of solitary nodule is its malignant potential. Thyroid nodule is an elusive clinical problem. Surgeons and Physicians are often required to make a diagnostic or management decision in its treatment. To study the Aim and Objectives: correlation between Clinical, Radiological, Cytological and Histopathological ?nding in patients who presented with “solitary thyroid nodule”. A prospective observational study, Ramakrishna Mission Materials and Methods:Study design: Study area: Seva Pratishthan Hospital, Kolkata, July 2019 to June 2022(3 years), 40 patients, Inclusion criteria: Study period: Sample size: Patients presenting with solitary thyroid nodule, Patients with multinodular goitre, patients with carcinoma Exclusion criteria: thyroid with distant metastasis, paediatric patients and those unwilling. Thorough history, clinical examination, Methodology: investigation (FNAC/USG/Isotope Scan, TSH), appropriate surgical intervention and HPE of excised specimen was done. Results: In our study of 40 cases, 28(70.0%) were colloid goiter, 7(17.5%) were papillary carcinoma, 2(5%) were follicular adenoma, 1(2.5%) was follicular carcinoma, 1(2.5%) was adenomatoid hyperplasia and 1(2.5%) was Hashimoto thyroiditis. 28(70%) cases underwent hemithyroidectomy, 11(27.5%) underwent total thyroidectomy and 1(2.5%) underwent hemithyroidectomy followed by revision total thyroidectomy. 2 cases of papillary carcinoma with enlarged neck nodes underwent total thyroidectomy with neck node dissection. Solitary nodule is most common in woman and in third Conclusion: and fourth decade of life, more common in the right lobe. USG and FNAC are common modalities of investigations with high speci?city and sensitivity. Isotope scan is only indicated to con?rm the toxic nodule. Malignancy reported in my study was 20%. Early diagnosis and prompt treatment will cure the disease since carcinoma thyroid is more curable amongst all cancers.
