Histologic variants of prostatic carcinoma are readily recognized. In this report, we describe a rare variant, adenoid cystic carcinoma, in a 75-year-old man previously diagnosed to have transitional cell carcinoma of the urinary bladder. The diagnosis of adenoid cystic carcinoma was made by the characteristic microscopic features of the tumor morphologically and immunohistochemically. Two mont...

The occurrence of primary carcinoma of the ureteral stump following radical nephrectomy for renal cell carcinoma is extremely rare; 7 patients with the disease have been reported previously. All these patients were males with transitional cell carcinoma. The current study reports the case of a 61-year-old woman, who presented with gross hematuria following a radical nephrectomy for local clear ...

Bladder cancer is one of the most common urological malignancies. Ninety percent of the bladder tumors are transitional cell carcinomas. The most important molecular mechanism in the development of carcinogenesis is the Deletions or inactivation of the cancer suppressor genes. Several suppressor gene loci have been closely associated with bladder cancer. These include p53 on chromosome 17p, ret...
