Background: E-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. Loss of the adhesive function of E-cadherin seems to promote invasive and metastatic properties of neoplastic cells. Objectives: The present study is a retrospective study aiming to evaluate the loss of E-cadher...

although bladder leiomyoma is rare, this is the most frequent nonepithelial benign tumor of the bladder. symptoms and treatment depend on location and size of the lesion as well. the optional treatment is a total enucleation or partial cystectomy, although in biopsy proved cases watchful waiting is an option, surgery should be considered as the tumor grows or symptoms are observed. the etiology...

background: the current study investigated the possible role of the cell cycle regulator, cyclin-dependent kinases regulatory subunit-2; the angiogenic factor, plateletderived endothelial cell growth factor; and the cell adhesive molecule, neural cadherin, as prognostic factors in schistosomal and non-schistosomal-associated urothelial carcinomas. we also investigated the possible correlation b...

one of the rarest tumors involving the urinary bladder is the pheochromocytoma. a case of pheochromocytoma of the urinary bladder in a young female suffering from headache and cystitis for many years is reported. twenty-four hour urine vma was normal. the patient was never hypertensive except during surgical manipulation of the tumor. biopsy of the bladder resulted in massive hemorrhage.

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 ...

Hepatoid variant of yolk sac tumor of ovary is an unusual tumor with an aggressive behavior. It is usually observed in young females, presents with abdominal complaints and is associated with raised α-fetoprotein (AFP) levels. It should be differentiated from other hepatoid tumors involving the ovary. A complete patient evaluation with gross, microscopy, and immunohistochemistry can identify th...
