Study of pre-operative neutrophil-lymphocyte ratio in urothelial carcinoma.

OBJECTIVES: Neutrophil-lymphocyte ratio (NLR), as an indicator of heightened systemic inflammatory response, predicts increased disease burden and poor oncological outcomes in urothelial carcinoma (UC). The study was undertaken with an aim to evaluate the association of NLR with clinicopathological variables and survival outcomes. METHODS: A total of 80 patients of UC were enrolled in the current retrospective study. Pre-operative NLR (within one month prior to the procedure), patient age, sex, tumour grade, pathological stage, recurrence free survival (RFS), progression free survival (PFS) and cancer specific survival (CSS) were recorded. We chose a cut-off value of 2.7 for NLR and patients were divide into two groups (NLR <2.7 and ≥2.7). RESULTS: NLR ≥2.7 was significantly associated with advanced tumour stage (p=0.001), but not with tumour grade (p=0.116). Progression (p=0.032) and death rates (p=0.026) were high in patients with NLR ≥2.7. Mean RFS (p=0.03), PFS (p=0.04) and CSS (p=0.04) were reduced in patients with NLR ≥2.7. On univariate analysis, NLR ≥2.7 predicted worse RFS (HR=2.928, p=0.007), PFS (HR=3.180, p=0.006) and CSS (HR=3.109, p=0.016). However, it was not an independent predictor of outcomes on multivariate analysis. CONCLUSIONS: Tumour stage and grade are the only independent predictors of RFS, PFS and CSS. High NLR at a cut-off value of ≥2.7 is associated with advanced pathological stage, but does not have an independent predictive value for RFS, PFS and CSS.

Histopathological Study of Benign Tumours of the Larynx: A Descriptive Study in Coastal Karnataka.

A laryngoscopically benign lesion with minimal hoarseness may turn out to be mimickers of malignancy or malignancy itself. Histopathological study is mandatory in such cases to rule out malignancy. A descriptive study of histopathological and laryngoscopic findings of benign laryngeal lesions were studies over a period of 4.5 years. Among the thirty-six patients studied, the mean age of the patients was 42 years. The most common presenting complaint was hoarseness of voice seen in 87.5% of cases. Twelve cases of vocal cord polyps were diagnosed based on clinical, laryngoscopical and histopathological features. Seven cases of vocal cord nodules, presenting with hoarseness of voice and laryngoscopic finding of a small nodular growth over the cord. Nine cases of laryngeal papillomas and papillomatosis showed branching papillae, lined by squamous epithelium with fibrovascular cores. A single case of amyloidosis and four cases of granulomatous lesions suggestive of tuberculosis were studied. One case each of rhabdomyoma and granular cell tumour was reported and confirmed by immunohistochemistry. Rare benign tumours and tumour-like lesions mimicking malignancy on laryngoscopy need histopathological evaluation. It is mandatory to study excised biopsies of the larynx as grossly similar lesions can vary from non-neoplastic to frankly malignant.

Clinico-histopathological Profile of Primary Paediatric Intra-abdominal Tumours: a Multi-hospital-Based Study.

Paediatric cancers are gradually on the rise in India. Its proportion among children aged < 15 years constitutes close to 5% of the total cancer affected population. A high proportion of this constitutes intra-abdominal tumours. This study was done to study the demographic profile, clinical features and management of intra-abdominal tumours among children. Data of all histopathologically confirmed patients aged < 15 years with various primary intra-abdominal tumours diagnosed from 2009 to 2019 were included in this study. The median age of the patients (n = 50) was 3 years (IQR 1.4, 6). The median age at diagnosis of cancer (n = 23) was 2.5 years (IQR 1, 4). Tumours were more common among males (70%). The most common tumour in this study was Wilm's tumour (17 (34%)). Forty-eight (96%) patients had malignant tumours. Fever was present among the majority (27 (54%)) of the patients. The most common anti-cancer drug used for management was Vincristine, used among 23 patients. Remission was more among infants with Wilm's tumour (P = 0.0221) and among patients with Hodgkin's lymphoma (HL) (P = 0.0444). Default with treatment was more among patients with stage 4 malignancy (P = 0.0186). Recovery following treatment was more among patients with germ cell tumour (P = 0.0082). Reasons for default with treatment in the late stages of malignancies need to be identified in future research studies.

Solid pseudopapillary epithelial neoplasm (SPEN) of the pancreas involving the distal body and proximal tail: A case report.

INTRODUCTION AND IMPORTANCE: Solid Pseudopapillary Epithelial Neoplasm (SPEN) of the pancreas is a rare cystic exocrine tumor of the pancreas most commonly occurring in women between 30 and 40 years of age. This case report aims to demonstrate the clinicopathological findings encountered and the management of a patient diagnosed with SPEN. CASE PRESENTATION: An 18-year-old woman with gradually progressive and intermittent abdominal pain in the epigastric region presented to our outpatient department. Physical examination elicited tenderness to palpation in the epigastric area, and imaging findings suggested SPEN of the pancreas involving distal body and proximal tail region of the pancreas. The tumor was resected, and the diagnosis was confirmed on histopathology examination. CLINICAL DISCUSSION: SPEN is a slow-growing tumor with a low-grade malignant potential, found incidentally in asymptomatic patients and symptomatic patients present with abdominal pain. The average tumor size is about 4 to 6 cm in diameter. Imaging is essential for diagnosis, and distal pancreatectomy with splenectomy was the most commonly reported procedure. CONCLUSION: It is crucial to consider a diagnosis of SPEN in women with abdominal pain in the epigastric region as early surgical resection of the tumor results in resolution and excellent prognosis.

Cysts that Still Persist: A Case Series of Cysticercosis on Histopathological Evaluation.

Cysticercus is the infective larval form of the cystode T. solium that causes cysticercosis. It is has been declared as one of the neglected endemic zoonoses by the WHO. Poor sanitation, and consumption of undercooked infected pork and raw vegetables contaminated by human feces are the potential sources. Cysticercosis can affect various organs. India is one of the endemic countries where the parasite is prevalent in many states. This study aimed to analyze and report cases of cysticercosis based on the histopathological diagnosis. This is a retrospective study that included cases which had been reported as cysticercosis on histopathology from 2010 to 2018 at a tertiary care hospital. The clinical presentation of these cases along with macroscopic and microscopic features were reviewed. There were six cases of cysticercosis that were diagnosed on histopathology during the study period. Among them, two cases were intramuscular lesions, three were subcutaneous, and one case was an intraventricular lesion in the brain. Three of the cases presented as cystic lesions. On histopathological evaluation, cysts were identified in four cases on macroscopy. Microscopically, the cross section of the cysticercus was seen in all six cases with associated inflammatory change. To conclude, cysticercosis can clinically present as a benign neoplastic or an inflammatory lesion. Microscopic findings dictate the diagnosis of cysticercosis, although histopathological evaluation is not common.

T-cell lymphomas in a tertiary care center of Mangalore.

BACKGROUND: The clinicomorphology and immunohistochemical features of T-cell lymphomas have been documented. AIM: The aim of the study was to evaluate the spectrum of clincopathological features of T-cell lymphoma with immunohistochemistry correlation in a tertiary care center. MATERIALS AND METHODS: The present study was conducted on 19 biopsy specimens received from the Department of Pathology, Kasturba Medical College, from referral hospitals of Mangalore city. Cases of nodal and extranodal T-cell lymphomas diagnosed between January 2012 and December 2015 were selected with evaluation of clinical data, histomorphological features, and immunophenotyping. Appropriate panel of antibodies was chosen after morphological evaluation of the cases. RESULTS: Of the 19 cases of T-cell lymphomas, 14 were nodal disease and 5 were extranodal disease. Among the nodal lymphomas, five were primary peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS), four were cases of lymphoblastic lymphoma, three were cases of angioimmunoblastic T-cell lymphomas, and two were cases of anaplastic large-cell lymphoma anaplastic lymphoma kinase (ALK) negative. In extranodal disease, two were mycosis fungoides of skin, one case each of subcutaneous panniculitis-like T-cell lymphoma, T-cell lymphoblastic lymphoma of tonsil, and T-cell lymphoma of the stomach. CONCLUSIONS: The diagnosis and subclassification of PTCLs is necessary for therapeutic and prognostic purposes.

Use of the term atypical cells in the reporting of ascitic fluid cytology: A caveat.

BACKGROUND: Abdominal paracentesis is a routine diagnostic procedure for assessment of patients with recent onset or worsening of ascites. OBJECTIVES: The objective of the study is to (1) review clinically confirmed cases of malignancy with negative, atypical, and suspicious cytology reports and provide reasoning for discrepancies and (2) recalculate sensitivity, specificity, and predictive values after review. MATERIALS AND METHODS: Papanicolaou smears of ascitic fluid paracentesis samples received over one calendar year were reviewed retrospectively by an expert in cytopathology blinded to the final clinical and/or histopathological diagnoses. Cases with discrepancies after review were noted. Sensitivity, specificity, and predictive values were calculated before and after review of slides. Data were analyzed using SPSS version 16. RESULTS: Malignant etiology was identified in 49/115 cases (42.6%) with female genital tract being the most common site of malignancy (22, 44.8%). The remaining 66 (57.4%) had a benign etiology with hepatic cirrhosis in 42 cases (63.6%). A review revealed discrepancies in five cases, three of which were earlier called negative for malignant cells (one case each of ovarian adenocarcinoma, cecal adenocarcinoma, and cholangiocarcinoma). Two cases of ovarian adenocarcinoma that were reported as atypical/reactive mesothelial hyperplasia showed malignant cells upon review. Sensitivity and specificity after review were 69.4% and 100%, respectively, with 100% positive predictive value. CONCLUSION: Being a minimally invasive procedure, abdominal paracentesis continues to be an important diagnostic tool in guiding patient management. A proper morphological assessment with adequate clinical information and correlation with other investigations can be used to arrive at a definitive diagnosis in most cases. The term "atypical" can be misleading and is often used for want of clinical information and is best avoided.

Clinicopathological spectrum of solitary Plasmacytoma: a single center experience from coastal India.

BACKGROUND: Plasma cell disorders are a rare group of hematological malignancies that accounts for 10% of all hematological neoplasms. Solitary plasmacytomas are rarer entities accounting for less than 5% of all the plasma cell dyscrasias. They encompass three subtypes - Solitary Plasmacytoma of Bone (SPB) and Solitary Extramedullary Plasmacytoma (SEP) and multiple solitary plasmacytomas (MSP). In this study, we discuss the clinical, histopathological and immunohistochemical characteristics of solitary plasmacytomas. METHODS: A 13 year retrospective analysis of solitary plasmacytomas was performed from a single tertiary care center. Bone marrow evaluation was done concurrently at the time of diagnosis to rule out the presence of multiple myeloma. RESULTS: A total of 29 cases fulfilled the diagnostic criteria for SP during the study period. SPB accounted for 55.2%, SEP for 44.4% and MSP for 3.4% of the cases. The most common sites involved were the paranasal sinuses and vertebrae. Other infrequent sites included lymph node, tonsil and lungs. The mean age of presentation of SPB was a decade later than SEP. A male preponderance was observed in both subtypes. CONCLUSION: Solitary plasmacytoma is a rare entity, the diagnosis of which requires a systematic approach. There is limited data available in the literature on the clinico-pathological characteristics of SP from India.

Lymphoepithelial Sialadenitis Involving HIV-Infected and Sjogren Syndrome Patients: A Cytologic Study.

Lymphoepithelial salivary gland cysts are rarely seen in autoimmune diseases particularly Sjogren syndrome as well as in HIV for which medical management is advocated. To study the morphology of these cysts, correlate with the disease process and assess the final outcome. Case series. Fine needle aspiration clinic. HIV-infected and autoimmune disease patients with lymphoepithelial cysts. Antiretroviral therapy for HIV-patients and anti-inflammatory drugs for Sjogren syndrome. Three HIV-infected patients (two children and one adult) and three middle aged female patients presented with parotid and submandibular cysts, two of which were bilateral along with submandibular (one each in the HIV and the autoimmune group). In the adult HIV-patient, the cyst was found at the inception of the disease while the other pediatric HIV-patients just crossed a decade. Of the other three cases of Sjogren syndrome, two were primary and one, secondary to rheumatoid arthritis. All the cysts regressed completely with treatment of the respective diseases which was confirmed by ultrasonograms. Lymphoepithelial cysts are produced by release of serous secretion by the acinar and ductal cells within the epithelial islands in the process of their destruction. Possibly, antibody mediated increased secretion in the initial stages also plays a role. Lymphoepithelial cysts of HIV patients may occur in the course of treatment, not necessarily in the beginning, though it resolves spontaneously. Lymphoepithelial cysts of primary or secondary Sjogren syndrome may be repressed sufficiently by anti-inflammatory/immunosuppressant treatment.

Utility of fine-needle aspiration cytology in the diagnosis of HIV lymphadenopathy.

BACKGROUND: India, being a developing country, harbors the third largest human immunodeficiency virus (HIV)-infected population in the world, and HIV-associated lymphadenopathy is commonly encountered. HIV lymphadenopathy is more commonly generalized and pathology ranges from reactive lymphoid hyperplasia to infections like tuberculosis to neoplasms such as lymphoma and Kaposi sarcoma. The study intended to assess the utility of fine-needle aspiration (FNA) cytology in HIV lymphadenopathy. MATERIALS AND METHODS: A retrospective FNA slide review of HIV-infected cases with lymphadenopathy received over a period of 2 years in the cytopathology department was performed. The clinicopathological characteristics, absolute lymphocyte count (ALC), and CD4 counts were analyzed. RESULTS: Seventy-nine lymph node aspirates were received from HIV patients over 2 years. The mean age at presentation was 39 years with a male:female ratio of 2.4:1. Cervical lymph nodes (62%) were more commonly affected. Tuberculous lymphadenitis was the commonest lesion (41.8%), followed by reactive lymphadenitis (24%), nonspecific granulomatous lymphadenitis (14%), suppurative lymphadenitis (8%), cryptococcal lymphadenitis (2%), lymphoma (9%), and metastasis (1%). CONCLUSION: Lymph node FNA in HIV/AIDS is not only useful in identifying those cases that require further evaluation, but also aids in categorizing various etiologies such as opportunistic infections, non-neoplastic, and neoplastic lesions. FNA is a less expensive, expeditious minimally invasive method for an early diagnosis that abets in deciding the treatment strategy, thus curtailing the associated morbidity and mortality.

A Case Report of Isolated Cysticercosis of Biceps Muscle.

INTRODUCTION: Cysticercosis is more commonly seen in developing countries like India caused by larval stage of Taenia solium. Neurocysticercosis is more commonly seen than isolated muscle involvement. There are very few sporadic cases of isolated biceps muscle involvement, but most of them are managed medically. We are reporting an isolated case of cysticercosis of biceps muscle managed surgically. CASE REPORT: A 32-year-old male, security personnel by occupation, comes with complaints of painful swelling of the right arm for past 1 week. There was no trauma to the limb and no similar swellings elsewhere in the body. On examination, there was an anteromedial tender swelling of mid-third of arm. X-ray was normal with soft tissue shadow on the anterior aspect. Ultrasound showed cystic lesion with central hyperechoic lesion. Magnetic resonance imaging of arm showed 7.7 mm × 4.8 mm lesion in anteromedial aspect of arm with surrounding edema s/o granuloma. The patient underwent excision of the cyst and biopsy was suggestive of cysticercosis and surrounding granuloma. CONCLUSION: Isolated cysticercosis of muscle is very rare, but when it is symptomatic and hindering in daily activities, surgical excision can be done for faster relief and early return to normal day-to-day activities.

The pitfalls in cytology diagnosis of poorly differentiated neuroendocrine carcinoma of lung and their treatment response.

CONTEXT: Lung is the most common site of small cell carcinoma (SCLC) - a poorly differentiated neuroendocrine carcinoma (PDNEC). SCLC comprises 15-20% of the invasive cancers of the lung. AIM: This study was conducted to appraise the accuracy and pitfalls of the diagnosis of PDNEC on cytology along with treatment responses if available. SETTINGS AND DESIGN: Retrospective study for 2 years yielded 21 cases on cytology. SUBJECTS AND METHODS: Slides of fine-needle aspiration of lymph nodes, the tumor, bronchial brush, and bronchoalveolar lavage specimens were used. The histological correlation was obtained as were treatment responses. RESULTS: Eighteen SCLCs were confirmed on review. Of these, 13 initial reports were concordant and five, discordant. The rest three cases which initially reported as SCLC were found to be negative (2) and combined SCLC (1). One SCLC with concordant initial and reviewed diagnoses failed to confirm on histopathology. The patients, all heavy smokers, were predominantly males in the seventh to eighth decade age group. The sensitivity and specificity of reviewed diagnoses were better than that of the original. The difference between histopathology and cytology diagnoses (reviewed and original) was statistically insignificant. All patients were categorized as "extensive stage" by positron emission tomography-computerized tomography, and five were treated with etoposide and cisplatin with/without radiotherapy. CONCLUSION: Age group (61-70) and gender (males) distribution were statistically significant. Intermediate variants of SCLC may be misdiagnosed as adenocarcinoma. Similarly, combined SCLC may be missed on cytology if the observer does not sustain a high index of suspicion. Unequivocal cytology diagnosis opposed to negative histopathology report demands repeat biopsy.

A Fortuitous Turn of Evidence in an Elderly Female - A Case of Pulmonary Fusariosis.

Pulmonary mycosis is seen infrequently in our country. It is more common in the immunocompromised. The infections caused by less known species like Fusarium have been found to be increasing in incidence in other parts of the world. We hereby report its occurrence in a 79-year-old, non-immunocompromised female who presented with pyrexia of unknown origin. Her Alanine Phosphatase (ALP) and Lactate Dehydrogenase (LHD) levels were raised. CT scan showed interstitial thickening in subpleural aspect of lungs and multiple enlarged lymph nodes in mediastinum. Liver showed multiple hypodense lesions. Metastasis was suspected for which Fine Needle Aspiration Cytology (FNAC) of liver was done which showed foci of regenerative hepatocytes with desmoplastic stromal tissue fragments and negative for tumour. Her Alpha Fetoprotein (AFP) was normal. The bronchial tree cytology showed endobronchial cells, dust-laden macrophages and chronic inflammatory cells along with fungi on Pap smear studies. This was confirmed by culture that grew Fusarium species. after one week of incubation. The acutely branching septate hyphae of Fusarium species are identical to those of Aspergillus species. In a patient who has a disseminated infection with a septate fungus, growth in culture is important to identify the specific organism and subsequently treatment with appropriate antifungals. In cases like ours, where the infection simulates malignancy, it is even more important to make the correct diagnosis to give the appropriate treatment.

O'Brien's Granuloma- A Case Report.

Actinic granuloma is a self-limiting chronic disorder with elastolytic granulomas, mainly of the sun exposed skin and unknown pathogenesis. We report a case of a middle aged woman with multiple annular erythematous lesions. Histopathology revealed degenerated elastic fibres with histiocyte aggregates surrounded by multiple giant cells suggestive of elastolytic granulomas. She also had associated dyslipidemia and hypothyroidism. Actinic granuloma is relatively rare in the Indian population and needs to be differentiated from conditions like sarcoidosis and granuloma annulare.

Morphological Spectrum of Basal Cell Carcinoma in Southern Karnataka.

INTRODUCTION: Basal Cell Carcinoma (BCC) is the most common skin cancer worldwide, which appears over sun-exposed skin as slow-growing, locally invasive lesion that rarely metastasizes. Many phenotypic presentations are possible. BCCs are more common in males and tend to occur in older people. Majority is found on the head and neck. Many histopathological subtypes have been defined including nodular, micronodular, cystic, superficial, pigmented, adenoid, infiltrating, sclerosing, keratotic, infundibulocystic, metatypical, basosquamous and fibroepitheliomatous. Mixed patterns are common. AIM: The aim was to study morphological spectrum of BCC in a tertiary care hospital in southern Karnataka. MATERIALS AND METHODS: This was a retrospective analysis of 100 cases of BCCs reported in the Department of Pathology over a 9-year period from 2006 to 2014. RESULTS: The mean age of presentation was 62 years. There was slight female preponderance (56%). The most common location was face (65%) and the most common presentation was ulceration (45%). Of the 100 BCCs, 50% were nodular, 13% infiltrating, 6% basosquamous, 4% superficial, 3% keratotic, 3% multinodular and 1% mixed. CONCLUSION: BCC, besides being the commonest cutaneous cancer, is also known for its numerous histological patterns which are shown to have prognostic implications. This study reveals the frequency of the various histological patterns of BCC in southern Karnataka, where it has been rarely studied before.

Type II endometrial cancers: A case series.

INTRODUCTION: Endometrial carcinoma ranks 3(rd) in India among gynecological malignancies. Endometrial cancer (EC) can be classified into two distinct groups - type I and type II, based on histology, which differs in molecular, clinical and histopathological profiles. Type II is nonestrogen dependent, nonendometrioid, more aggressive and carries poor prognosis. Although type II cancers contribute only about 10% of EC incidence, they present at advanced age and cause approximately 50% recurrence and deaths with a low 5-year, overall survival rate. Type II EC are also characterized by genetic alterations in p53, human epidermal growth factor-2/neu, p16 and E-cadherin. MATERIALS AND METHODS: Endometrial carcinomas diagnosed from endometrial biopsies and hysterectomy specimens received in the Department of Pathology, Kasturba Medical College, Mangalore, from January 2007 to June 2012 were included in the study. Clinicopathological analysis of the 84 cases of EC was done with emphasis on morphology. p53 immunostaining was performed in two cases of serous carcinoma. RESULTS: Out of a total of 84 cases of EC, ten cases were of type II (11.9%). Out of which, eight were serous carcinoma (9.5%) and two clear cell (2.4%). p53 immunostain was strongly positive in the serous papillary carcinomas. The age of the patients ranged from 45 to 75 years. Myometrial invasion was more than half. Treatment was hysterectomy followed by aggressive chemotherapy. CONCLUSION: Of the type II EC, serous carcinoma is the most common type. Clinical presentation and prognosis differs in comparison to type I EC, thus the recognition of this type of EC is pivotal.

A Histomorphological Pattern Analysis of Pulmonary Tuberculosis in Lung Autopsy and Surgically Resected Specimens.

Background. Tuberculosis (TB) is a major cause of morbidity and mortality globally. Many cases are diagnosed on autopsy and a subset of patients may require surgical intervention either due to the complication or sequelae of TB. Materials and Methods. 40 cases of resected lung specimens following surgery or autopsy in which a diagnosis of pulmonary tuberculosis was made were included. Histopathological pattern analysis of pulmonary tuberculosis along with associated nonneoplastic changes and identification of Mycobacterium tuberculosis bacilli was done. Results. The mean age of diagnosis was 41 years with male predominance (92.5%). Tuberculosis was suspected in only 12.1% of cases before death. Seven cases were operated upon due to associated complications or suspicion of malignancy. Tubercular consolidation was the most frequent pattern followed by miliary tuberculosis. The presence of necrotizing granulomas was seen in 33 cases (82.5%). Acid fast bacilli were seen in 57.5% cases on Ziehl-Neelsen stain. Conclusion. Histopathology remains one of the most important methods for diagnosing tuberculosis, especially in TB prevalent areas. It should be considered in the differential diagnosis of all respiratory diseases because of its varied clinical presentations and manifestations.

Primary clear cell carcinoma of the nasopharynx.

A 22-year-old female with epistaxis and nose block had a pink, smooth, mucosa covered lesion occupying the nasopharynx. The histopathology and immunohistochemistry of the lesion confirmed the diagnosis of clear cell carcinoma (CCC). Detailed evaluation ruled out a primary tumor elsewhere in the body. After complete excision of the tumor patient received radiotherapy (60 Gray in 30 fractions over 6 weeks). Patient is recurrence free on her 3-year follow-up. Primary CCC of the head and neck is rare. In the past 30 years, less than 100 cases have been reported in English literature. Out of these, only nine cases had nasopharyngeal origin. The literature review of those cases along with our case report suggest that complete excision of nasopharyngeal CCC along with radiotherapy leads to prolonged recurrence free interval. However, extensive tumors of nasopharynx exhibit poor prognosis with repeated local recurrences.

Coexistence of benign ovarian serous cystadenoma and tuberculosis in a young woman.

Genital tuberculosis involving the ovary in a non-immunocompromised individual is rare. We report a case of coexisting ovarian serous cystadenoma and tuberculosis in a 29-year-old Indian woman. Clinical examination revealed the presence of an abdominal mass suspicious for ovarian neoplasm. Histopathological evaluation revealed ovarian neoplasm and concomitant tuberculosis. To the best of our knowledge, and after an extensive search of the literature, the coexistence of benign ovarian neoplasm and tuberculosis has not been previously documented.
