[Micropapillary urothelial carcinoma of the bladder: case report and review of the literature].

Micropapillary urothelial carcinoma (MCP) of the urinary bladder is an rare anatomopathology variant of aggressive behaviour. It is usually found as a high grade and stage carcinoma, and doesn't differ clinically from normal cell carcinoma of the bladder. Treatment should be early and aggressive, because radiotherapy and chemotherapy have shown limited results the therapy is surgically based. The diagnosis of this disease is required because its metastasic capacity is associate with a significantly increased mortality risk. In this study we report the case of a 64 years old man with a long development hematuria diagnosed of Micropapillary carcinoma infiltrating the bladder involving the ureter.
