Primary bladder tumor is a frequent urological malignancy, whereas the incidence of secondary bladder tumor from a distant organ is quite rare. Secondary bladder neoplasms represent 1% of all malignant bladder tumors, of which distant metastases from stomach account for about 4% of cases. We present the case of a 30-year-old male who underwent partial gastrectomy for Signet-ring cell carcinoma ...

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 ...

Neuroendocrine tumors (NETs) can be found in most organs, as well as in the urinary bladder. Some of the clinical and pathologic features of these tumors may be characteristic of the organ of origin, but most of the properties are shared by neuroendocrine neoplasms regardless of their anatomic site. In the bladder, NETs comprise less than 1% of all bladder tumors and can be found in a pure form...

Aims. Metastatic malignant melanoma of the urinary bladder is a rare clinical entity, with only twenty-three published cases to date. We present a case of this rare entity, a thorough review of the literature, and differential diagnosis of melanoma in the bladder. Methods and Results. A 55-year-old woman with a history of malignant melanoma of the right thigh, excised eight years ago, presented...

Primary ureteral neoplasms are very rare and its prevalence is less than 1% of all genitourinary neoplasms. We report a symptomatic giant ureteral fibro epithelial polyp in adult women presenting as a bladder mass which was resected ureteroscopically and reported at the first time from Iran. Cystoscopy is growing use in the treatment of urinary tract lesions Cystoscopy can be used in large lesi...

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 ...

INTRODUCTION Loss of heterozygosity (LOH) is frequently observed in urinary bladder neoplasms. In the reported study, an attempt was undertaken to determine the loss of heterozygosity of TP53(17p13), RB1(13q14), CDKN2A/ ARF(9p21) genes in DNA from neoplastic tissue, collected from patients with diagnosed urinary bladder carcinoma, and to compare the results with those of LOH evaluation in DNA i...

conclusions the intervention bundle prompted increased administration of psdivc and documentation. similar centres may benefit from an intervention to improve compliance. results sixty-four patients in group a underwent turbt prior to introduction of the intervention bundle. fifty-four patients had non-muscle invasive bladder cancer (nmibc), which would have been eligible for psdivc. fifteen (2...
