signet ring cell urothelial carcinoma

Tuesday 2 November 2010

signet ring cell variant of urothelial carcinoma; ring cell urothelial carcinoma

Primary signet ring cell carcinoma of the urinary bladder is a rare and aggressive histologic subtype of adenocarcinoma.

In general, this tumor occurs in the middle age, and clinical presentation does not differ from transitional cell carcinomas. The prognosis is often poor, given the advanced stage at diagnosis.
