Urinary bladder paraganglioma is a rare neuroendocrine tumor and nonfunctional bladder paraganglioma is extremely rare and difficult to diagnose due to their non-secreting nature. We report a rare female case of nonfunctional bladder paraganglioma with detailed clinicopathological data and follow-up information. The patient presented with supra-pubic pain. Computed tomography (CT) revealed a 11...

Cyclooxygenase (COX)-inhibiting drugs have antitumor activity in canine and rodent models of urinary bladder cancer. Two isoenzymes of COX have been identified, COX-1 and COX-2. The purpose of this study was to characterize COX-1 and COX-2 expression in human invasive transitional cell carcinoma of the urinary bladder by immunohistochemistry and Western blot analysis. COX-2 was not expressed in...

To understand functions and diseases of urinary bladder, it is important to define its molecular constituents and their roles in urinary bladder biology. Here, we performed genome-wide deep RNA sequencing analysis of human urinary bladder samples and identified genes up-regulated in the urinary bladder by comparing the transcriptome data to those of all other major human tissue types. 90 protei...

Inflammatory myofibroblastic tumors (IMTs) rarely occur in the urinary bladder. It is apparently difficult to distinguish these tumors from other malignant spindle cell proliferations. Herein, we report a case of IMT of the urinary bladder with enlarged pelvic lymph nodes. The definitive pathological diagnosis could not be established by biopsy. Instead, the diagnosis of IMT of the urinary blad...

The primary mucinous adenocarcinoma of the bladder is an extremely rare urologic entity, which is less than 2% of all urinary bladder tumours and often presents in advanced stage. A 68-year old gentleman was diagnosed with a primary mucinous adenocarcinoma of the bladder from biopsy of anterior abdominal wall ulcer. Immunohistochemistry was done to rule out metastasis from colon and prostate an...

BACKGROUND The primary mucinous adenocarcinoma of the bladder is an extremely rare urologic entity, which is found in less than 2% of all urinary bladder tumours and is often presented as metastatic. CASE PRESENTATION A 69-year old male patient was diagnosed with a primary mucinous adenocarcinoma of the bladder after undergoing a transurethral resection of a bladder tumour and complete examin...

opium use is one of the most common forms of substance abuse in iran and there are some evidence indicating it is a risk factor of transitional cell carcinoma (tcc) of the urinary bladder. the majority of opium users are also cigarette smokers, so consideration of the high prevalence of smoking which is the most important risk factor of tcc of the urinary bladder among opium users is essential ...

Regulation of the VEGF-VEGF receptor system was examined in the urinary bladder after acute (2-48 h) and chronic (10 days) cyclophosphamide (CYP)-induced cystitis. ELISAs demonstrated significant (P < or = 0.01) upregulation of VEGF in whole urinary bladder with acute and chronic CYP-induced cystitis; however, the magnitude of increase was greater after acute (2-4 h) cystitis. Immunohistochemis...

cystoscopy and urinary cytology are currently the basis for diagnosis and ‎follow-up of bladder tumors. research to find a sensitive and specific tumor ‎marker for diagnosis of bladder tumor is actively underway, however, due to low sensitivity ‎and high cost of cytology. this cross-sectional study was performed in 65 patients to evaluate whether urinary bladder ‎cancer (ubc) antigen level can ...

Embryonal rhabdomyosarcoma (ERMS) of the adult urinary bladder is a rare malignant tumour. Inflammatory myofibroblastic tumour (IMT) of the bladder is a benign genitourinary tumour that may appear variable histologically but usually lacks unequivocal malignant traits. Techniques like flow cytometry and immunohistochemistry may be used to differentiate these two tumours. Our patient, a 46-year-o...
