A Histopathological Study of the Spectrum of Skin Lesions in a Tertiary Care Hospital: A Retrospective Study.

Background The skin is the largest organ of the body with many different functions. All age groups are affected by skin diseases, which are widespread in underdeveloped nations. From a straightforward vesicular non-neoplastic lesion to a catastrophic neoplastic lesion, skin disorders exhibit a wide variety of geographic patterns. To make an accurate diagnosis, identify etiological agents, and assist a dermatologist or clinician in selecting the best course of treatment, a skin biopsy must undergo histopathological analysis. The present study was conducted to investigate the histological diagnosis of skin lesions, establish the distribution by age and sex, identify the most prevalent skin lesions, and further subclassify the most prevalent condition. Methodology A retrospective, cross-sectional study was conducted in the Department of Pathology at Datta Meghe Medical College, Wanadongari, Nagpur over the course of a year. Hematoxylin and eosin were used to stain a total of 50 skin biopsy samples, with special stain when necessary, and then examined. Results The study involved a total of 50 patients, with 39 (78%) males and 11 (22%) females. With 16 (32%) cases in the 21-30-year age group, the early age group preponderance was recorded. Overall, 16 (32%) cases had microbial diseases, followed by eight (16%) cases with non-infectious vesicobullous diseases and vesicopustular disease, and five (10%) cases with non-infectious erythematous papular and squamous disease. In 12 (24%) cases, leprosy was the most prevalent microbiological disease. In five (10%) cases, pemphigus vulgaris was the most prevalent vesicobullous condition. Psoriasis, which was present in two (4%) cases, was the most common non-infectious erythematous papular and squamous disease. Squamous cell carcinoma, which was seen in seven (14%) cases, was the most prevalent neoplastic lesion. Conclusions In skin lesions, males outnumbered females. Patients in the younger age groups were most commonly involved. Leprosy and squamous cell carcinoma were, respectively, the most prevalent non-neoplastic and neoplastic skin lesions in our study.

A Rare Case of Uterine Myxoid Leiomyosarcoma.

A 49-year-old female patient was referred to a tertiary care hospital with a history of postmenopausal bleeding and abdominal pain that had persisted for the last two months. An abdominal examination revealed a huge mass that had been present for 12 weeks. A fibroid uterus was suggested by USG. A biopsy was done and sent to histopathology which revealed myxoid leiomyoma. Subsequently, the patient underwent total abdominal hysterectomy without bilateral salpingo-oophorectomy. Histopathological examination confirmed the diagnosis of myxoid leiomyosarcoma (MLMS) of the uterus.

Malakoplakia of the Gallbladder: A Case Report.

Histiocytes are cells that are involved in the immune responses of the body. They are unable to properly break down the bacterial material in malakoplakia, a chronic granulomatous histiocytic disease that occurs in immunocompromised patients and autoimmune conditions. Very few reports of these lesions exist, as those that occur in the gallbladder. It typically affects the urinary bladder, alimentary tract, cutaneous, hepato-biliary, and male and female genital systems. These lesions are usually incidental findings that result in patients being misdiagnosed. A 70-year-old female presented with right lower quadrant abdominal pain, and malakoplakia of the gallbladder was diagnosed. Histopathology findings revealed malakoplakia of the gallbladder, and the same was confirmed with special stains such as periodic acid-Schiff (PAS). This case highlights the role of gross and histopathology findings as a clue to the diagnosis, which helps the surgeon with further management.

KIT (CD117) Positive Huge Primary Malignant Extra Gastrointestinal Stromal Tumors (EGISTs) Arising From Jejunal Mesentery: A Rare Case Report.

Tumors arising outside gastrointestinal systems are known as extra gastrointestinal stromal tumors (EGISTs). Outside gastrointestinal sites include the mesentery, omentum, peritoneum, pancreas, and liver. Our case highlights a rare occurrence of an EGIST in jejunal mesentery in a 45-year-old male with an asymptomatic large abdominal growth and weight loss. A contrast-enhanced multi-dimensional computed tomography scan showed a large heterogeneous mass in the left hypochondrium. lumbar, and paraumbilical regions. Later, the patient underwent surgical resection of the tumor along with the involved jejunal segment and small tumor masses in the mesentery. Histopathological examination reported a malignant EGIST of mesentery and invasion into the jejunum, further confirmed by immunohistochemistry (IHC) markers like CD117 and smooth muscle actin with a high proliferative index (Ki67). One should be aware that these are different from other malignancies arising from the mesentery. Their cell of origin is different and needs a specific type of treatment. The clinical history, radiological findings, histopathology, and IHC help in diagnosing especially when they are arising from unusual areas like jejunal mesentery. Surgical intervention and chemotherapy are mainstay treatments.

A comparison of swab types on sample adequacy, suspects comfort and provider preference in COVID-19.

AIM: This study was aimed to compare the virological, suspect reported outcomes and provider preferences during COVID-19 swab taking procedure used for sampling. METHODS: The COVID-19 suspects are subjected to nasopharyngeal (NP) and oropharyngeal (OP) swabs for testing. Two types of swabs (Nylon and Dacron) are used for sample collection. Prospectively each suspect's response is collected and assessed for self-reported comfort level. The provider's experience with each suspect and virological outcomes recorded separately. The sample adequacy was compared based on swab types and demographic characteristics. RESULTS: A total of 1008 COVID-19 suspects were considered for comparison of various outcomes. Dacron and flocked Nylon swab sticks are used for taking 530 and 478 samples, respectively. Suspects who underwent the procedure using Nylon swabs were six times more likely to have pain/discomfort compared to when Dacron swab was used (Adj RR (95% CI: 6.76 (3.53 to 13, p=0.0001))). The providers perceived six times more resistance with the Nylon swabs compared to Dacron Swabs (Adj RR (95% CI: 5.96 (3.88 to 9.14, p=0.0001))). The pediatric population had a higher rate of blood staining in Dacron swab [Dacron 66 (80.5%); Nylon 51 (54.8%) p=0.0001]. The sample adequacy rate and laboratory positivity rate were not significantly different from each other. CONCLUSIONS: Given the comparable virological outcomes, the difference in suspect and providers comfort should drive swab selection based on characteristics of the suspects. The bulbous Nylon swab caused more pain/discomfort in adults compared to Dacron.

Role of Computed Tomography Findings in the Quest of Understanding Origin of Antrochoanal Polyp.

Aetio pathogenesis of antrochoanal polyp (ACP) remains unclear. Correlation of clinical, computed tomography (CT) and histopathological findings is attempted in this study for understanding of their origin. A retrospective chart and image review of 22 patients having ACP was done for clinical, histopathological and CT findings on affected and non affected side for extent of opacificattion, thickness of alveolar bone (AB) in the region of medial wall and the floor of maxillary sinus. Also, widening of accessory ostium was measured and compared. The mean of average thickness of AB medially on affected side was [30.91/11.27] [mean (mm)/SD)] compared to non affected side [55.60/20.74] p = 0.0001 (p < 0.05). The vertical AB thickness at floor on affected side [34.05/14.69] versus [68.14/35.29] p = 0.0001. Ipsilateral side accessory ostium widening on affected was measuring [91.45/57.00] against [55.32/38.96] p = 0.018. The additional CT findings in present study showed reduction in thickness of AB in the medial part and floor of maxillary sinus region. These findings to our knowledge have not been reported in the literature till date. The reduction in bone thickness of AB substantiates theory of antral cyst in origin of ACP. However, their association with embryonic dental lamellae needs further evaluation.

Non Functional Unilateral Adrenal Myelolipoma, A Case Report.

Adrenal myelolipoma is characterized by presence within the adrenal gland of mature adipose tissue and active bone marrow elements. Owing to their non functional nature most cases are incidental, either at autopsy or through computer tomography scan. Occasionally the lesions attain a large size to become clinically apparent. We present a case of a 58-year-old female with mass per abdomen. Preoperative computer tomography scan of abdomen, hormonal and urine analysis showed features of non functional adrenal myelolipoma. Gross specimen consists of unilateral ovoid mass, external surface having capsule with adherent fat and areas of congestion. Microscopic examination showed well encapsulated tumour tissue composed of mature adipose tissue with major blood forming elements like myeloid, erythroid and megakaryocytic series. The diagnosis was confirmed by histopathological examination of right sided adrenalectomy specimen.
