title: [Plasmacytoid carcinoma. Five case reports of a rare variant of urothelial carcinoma].
abstract: Plasmacytoid carcinoma is a rare variant of urothelial carcinoma and is characterised by distinct histopathological and clinical characteristics. The incidence varies between 2.7% and 3.1% of all muscle-invasive urothelial carcinoma. It is an aggressive, high-grade tumor with poor prognosis. Negative E-cadherin expression seems to be important for exact diagnosis. Systemic chemotherapy of plasmacytoid carcinoma could lead to prolonged patient survival.
