Definition
Rare variant of urothelial carcinoma composed of cells having a morphological resemblance with plasma cells or monocytes.
Clinical Features
Incidence
It is a very rare variant, accounting only 3% of all invasive urothelial carcinomas.
Age
The age of presentation of the disease varies from 48 to 89 years, with a mean of 68.
Sex
Plasmacytoid urothelial carcinoma is more common in men than in women, with a male-to-female ratio of 2/3:1.
