Histopathological Spectrum of Non-neoplastic and Neoplastic Lesions of Urinary Bladder

Introduction: Urinary bladder is a site of various non-neoplastic and neoplastic lesions, both of which can present with hematuria. Cystoscopy allows for direct visualization of the bladder mucosa and also obtaining tissue for histopathologic evaluation. The most common non-neoplastic and neoplastic lesion of the urinary bladder is non-specific cystitis and urothelial carcinoma respectively. Materials and methods: This study is a 4-year retrospective study conducted in the Department of Pathology at Patan Hospital, Nepal. All cases from the urinary bladder i.e., both cystoscopic and cystectomy samples were included in the study. Hematoxylin and eosin-stained slides were re-evaluated whenever required. Results: A total of 145 cases were included which consisted of 17 cystectomy specimens and 128 cystoscopic biopsies. There was a male predominance. The non-neoplastic and neoplastic cases consisted of 32% and 68% respectively. Chronic non-specific cystitis and high-grade infiltrating urothelial carcinoma were the most common non-neoplastic and neoplastic lesions respectively. 56.1% of cystoscopic biopsies had the presence of detrusor muscle with 21.7% showing its invasion. Conclusions: Urinary bladder lesions have a wide spectrum ranging from non-neoplastic to neoplastic conditions. The presence of detrusor muscle in a cystoscopic biopsy, and its evaluation for invasion helps in diagnosis and further planning of patient management.

Neoplastic Lesions

Introduction: Non-neoplastic urinary bladder lesions are not life threatening, but are an important source to cause clinical symptoms and signs. However, neoplasms of the bladder are a source of morbidity, mortality, and exhibit more clinical challenges. Cystoscopy provides overall information about an anatomical/pathological condition of the urinary bladder which will be helpful for patients' management. A cystoscopic biopsy is a primary diagnostic tool for diagnosing urinary bladder cancer. Objectives: The objective of the study was to find the frequency and histomorphological characteristics of urinary bladder lesions in Dhulikhel Hospital, to find the clinical presentation of urinary bladder lesions and to grade the urothelial tumors based on the World Health Organization (WHO)/ International Society of Urological Pathology (ISUP) classification 2004. Methodology: This was a retrospective, cross-sectional, observational study carried out in the Department of Pathology, Dhulikhel Hospital-Kathmandu University Hospital. Convenient sampling was done. All cystoscopy biopsies received from January 2014 to December 2018 were studied. All tissue blocks were retrieved, cut, and stained with Hematoxylin and Eosin. The stained slides were examined under a light microscope by the primary investigator. Result: A total of 70 cystoscopic biopsies were analyzed. The majority of patients 20 (28.6%) were in the age group between 60 and 69 years and males were predominant 43 (61.4%). The neoplastic lesions constituted 40 (57.1%) of all bladder lesions, among them urothelial carcinoma accounted for 38 (54.2%). Similarly, chronic cystitis 27(38.6%) was the most common non-neoplastic lesion. Conclusion: The study found that the neoplastic lesions were commonly encountered in urinary bladder lesions. Among them, lowgrade urothelial carcinoma was the most common bladder tumor. However, most of the non-neoplastic lesions were inflammatory in origin. Cystoscopy combined with histomorphological examination helps in the early detection of bladder lesions.

A wide spectrum of normal, benign, premalignant, and malignant lesions may occur on the vulva. Symptoms of vulvar disorders may be non-specific. Empiric treatment of vulvovaginal symptoms is common but usually not helpful. Though the varied clinical presentation and diverse histopathological spectrum of vulvar lesions have amazed Pathologists, only a few studies have been reported in the literature. The present study consists of a histopathological spectrum of vulvar lesions. 1.To evaluate the histopathological spectrum of vulvar lesions. 2. To compare the incidences of non-neoplastic and neoplastic lesions of the vulva. Present study includes all types of vulvar lesion specimens received in the Department of pathology over a period of four years. All thirty-nine vulvar biopsies received in the Department of Pathology were studied for histomorphologic features. The lesions were categorized as non-neoplastic, neoplastic. The neoplastic ones were further divided into benign, malignant, and premalignant. The age of the women ranged from 15 to 69 years (mean 36.18±12.71) with the maximum number of patients between 30 to 40 years of age. Non neoplastic lesions were more common (22; 56.4%) than the (17; 43.6%) neoplastic lesions. There were 15(38.5%) benign lesions while 2 cases (5.13%) were malignant. Among the non-neoplastic lesions, Bartholin's duct cyst was the most common histopathologic diagnosis (35.9%). The fibroepithelial polyp was the most common benign neoplastic lesion constituting 15.3%. In the present study nonneoplastic lesions were more common than neoplastic lesions. Among the neoplastic lesions, benign neoplasms were more frequent than malignant lesions.

Introduction: The lesions of urinary bladder both non-neoplastic and neoplastic pose a common source of both morbidity and mortality. An accurate diagnosis of these lesions requires cystoscopy which allows a direct visualization of the bladder mucosa and biopsies of suspected lesions. Urinary bladder cancer is sixth most common cancer worldwide and represents a heterogeneous group of neoplasms. The current study aimed to study the different bladder lesions and its clinical features to detect it in early stage and as a mainstay option in the diagnosis and follow up. Materials and methods: This was a retrospective analysis of biopsies of urinary bladder submitted to the department of pathology over a period of 12 months. The study was approved by the institutional review board of the Universal College of Medical Sciences (UCMS-TH). All the urinary bladder biopsies received in the department were included in the study whereas autolysis of specimen and inadequate biopsies were excluded. Results: Among the 36 cases of urinary bladder lesions, the majority (35.36%) were in age group 61-70 years (22.33%). The patients had combination of lower urinary tract symptoms, the commonest being hematuria. 30.55% had non-neoplastic lesions and 69.55% had neoplastic lesion. Among non- neoplastic cases, 5.55% had chronic granulomatous inflammation. Most common neoplastic lesions was infiltrating urothelial carcinoma (n=6) followed by non- invasive urothelial neoplasia (n=5). Conclusion: A variety of lesions occur in urinary bladder and is commonly encountered by pathologist. Hematuria was commonest symptom and the clinicians investigated these patients further, which led to discovery of the urothelial tumors. Identification of these patients has an important impact on prognosis as well as on therapeutic approach.

BACKGROUND: Urinary bladder cancer is second most common cancer after prostate cancer in the genitourinary system. Urothelial Carcinoma is the commonest tumour type accounting for 90% of all primary tumours of the bladder Histopathological analysis of cystoscopic bladder biopsy and Transurethral resection of the bladder tumour (TURBT) material are the mainstay for cancer diagnosis. This study was aimed to determine the frequency of different types of neoplastic lesions of the urinary bladder and to determine the grade and stage of urothelial tumours. MATERIAL METHOD: The study was carried out in the Department of Pathology, Rajendra Institute of Medical Sciences (RIMS), Ranchi from January 2018 to June 2020 and included 30 cases of cystoscopic biopsies and TURBT specimens. RESULTS: Out of 30 cases of neoplastic lesions, majority were of high grade papillary urothelial carcinoma (n=14, 46.67%) followed by low grade papillary urothelial carcinoma (n=9, 30%), 3 cases (10%) were of PUNLMP, 2 cases (6.66%) of papilloma and 1 (3.33%) case each of moderately differentiated squamous cell carcinoma and extra nodal NHL. The most common age group was 41-50 years and 51-60 years with 9 (30%) cases each. Muscle invasion was seen only in high grade papillary urothelial carcinomas. CONCLUSION: High-grade urothelial carcinomas with lamina propria and muscle invasion are the most common neoplastic lesion of urinary bladder with significant morbidity and mortality. Muscle invasion and grading, as per TNM staging, are valuable prognostic factors.

Background: A variety of mass lesions occur within the paranasal sinus (PNS) and nasal cavity and thus it becomes mandatory for otorhinolaryngologist to elicit detailed history and thorough examination before reaching a final diagnosis. This is retrospective study of all sinonasal masses who were undergone surgical management in the institute of rural India and so in the environment.Methods: This is a retrospective observational study of 70 patients with sinonasal masses treated at a rural tertiary care hospital in rural western Maharashtra from period of Jan 2016 to May 2018. History, clinical assessment and histopathological examination (HPE) was done in all cases as per hospital record supplemented by radiological investigation as per requirement. The patients were grouped as per their histopathological diagnosis as non-neoplastic/inflammatory and neoplastic.Results: A total of 70 patients were analysed age ranging (11-70 years). Majority of the patients were in the age groups 21-40 years (47%). There were 43 (61%) male and 27 (39%) female with M:F ratio 1.6:1. On HPE, 50 (71%) cases were non neoplastic/inflammatory and 20 (29%) cases were neoplastic lesions. HPE revealed that 50 (71%) cases were non neoplastic and 20 (29%) cases were neoplastic lesions.Conclusions: Sinonasal masses have various differential diagnoses. They are fairly common with male predominance. Benign conditions show a peak during 2nd to 4th decade of life while malignancy increasing with the age after 4th decade. In non-neoplastic lesion, Allergic nasal polyp is the commonest histological pattern seen while in malignant lesions squamous cell carcinoma is noted with 100% male predominance.

Background: Neoplastic and non-neoplastic urinary bladder lesions are the main reasons for morbidity and mortality throughout the world. Amongst these, urothelial carcinoma is a common primary tumor of urinary bladder (90%). The objective of this study is to determine the profile of various urothelial lesions received in Army Hospital within 5 years of period.Materials and methods: Five years retrospective study of cystoscopic biopsies and radical cystectomy specimens were carried out in Department of Pathology, Army hospital.Results: Out of 53 cystoscopic biopsies and radical cystectomy specimens, 42 were neoplastic and 11 were non neoplastic lesions. Thirty six urothelial carcinomas were observed out of which 20 were high grade urothelial carcinoma and 16 were low grade. Out of 20 high grade urothelial carcinoma, 17 had muscle invasion and 3 had invasion upto lamina propria. Of 16 low grade urothelial carcinoma, 12 were noninvasive, 2 had invasion upto lamina propria and 2 had muscle invasion. Papilloma was the commonest benign lesions found (7.1%) followed by papillary urothelial neoplasms of low malignant potential (PUNLMP) (2.4%) and hemangioma (2.4%).Conclusion: This article have highlighted upon the importance of histopathological study in evaluating urinary bladder lesions. Also, it has helped in determining that neoplastic lesions were more common than non-neoplastic lesions as seen in our study. A great majority of neoplastic lesions were of urothelial origin. Cystoscopic studies and biopsies help in early detection of bladder neoplasms and they form the mainstay of the diagnosis and follow up.

Rule Out

Villous morphology in urinary bladder biopsy is a relatively uncommon finding. Villi are slender, finger-like structures that are commonly seen in the small intestine or in neoplastic lesions of gastrointestinal lineage/differentiation. Importantly, placenta also exhibits villi that are morphologically and functionally different from the intestinal one. Majority of the neoplastic lesions of urinary bladder are urothelial in origin with a minor subset showing glandular differentiation. While the presence of benign villi in urinary bladder biopsy necessitates a search for an occult perforation, provided a sample mismatch is ruled out, cytoarchitecturally abnormal/dysplastic villi indicate a neoplastic lesion of the urinary bladder encompassing villous adenoma and adenocarcinoma and urothelial carcinoma with villoglandular differentiation. The dysplastic villi in urinary bladder also imply a lower gastrointestinal endoscopy to rule out a colorectal primary. The development of the villous lesions in the urinary bladder and the colorectum are embryologically related and pose a major diagnostic challenge to the clinicians and surgical pathologists due to identical histomorphology and immunohistochemistry. We tend to discuss the morphological differentials and diagnostic approach to the villous lesions in the urinary bladder biopsy.

Urinary bladder tumors were one of the most common entities of urological pathology. Neoplastic & nonneoplastic lesions of urinary bladder were the common reasons for morbidity and mortality throughout world. Among neoplastic lesions, urothelial carcinoma is a common primary tumor of urinary bladder. The aim of this retrospective study was to determine the spectrum of various urothelial lesions from cystoscopic bladder biopsies received over a period of 3 years. All the urinary bladder biopsies received with two inadequate biopsies were included in this study. Out of 54 biopsies received, 12 were non neoplastic & 40 were neoplastic cases and two were inadequate biopsies. Majority of the cases were in 60-79 years age group. Males were affected more than females ( 2.85:1 ratio). Majority of the neoplastic lesions were urothelial carcinomas. Conclusion : Among the bladder tumors ,urothelial carcinoma was the most common type, among these, high grade urothelial carcinoma was common in our study. Non invasive were more common than invasive carcinoma.Identification of grade &invasion into muscle layer has an impact on prognosis as well as on therapeutic approach.
