Primary signet-ring cell adenocarcinoma of the bladder-A case report and review of literature.

Cases of adenocarcinoma of the bladder are extremely low - 2%, respectively. Primary signet-ring cell carcinoma (SRCC) of the bladder accounts for 0.12-0.6% among the different histological subtypes of bladder carcinomas. We present a rare case of SRСС with clinical manifestations of hematuria (two times) treated with transurethral resection of the bladder (TURB). Primary ring cell carcinoma of the bladder is an extremely rare and aggressive tumor. In this case, presented by us, probably due to early diagnosis and radical resection, the prognosis is encouraging.
