title: [Bladder carcinosarcoma: case report with immunohistologic study].
abstract: We present a new case of carcinosarcoma of the bladder. This tumor is generally considered to be a rare one, has an uncertain aetiology and very poor prognosis, composed by mesenchymal and epithelial elements. It is an aggressive tumor with a short clinical course. At present radical cystectomy is the treatment of choice.
