[Carcinosarcomas of the bladder. Immunohistochemical study in 3 cases].
We present 3 cases of carcinosarcoma of the bladder. We discuss the value of histochemistry on their diagnosis. We compare them to similar tumors reported in the medical literature. Like fusocellular carcinoma, carcinosarcoma finally appear as a morphological variant of high grade urothelial carcinoma, often difficult to diagnose. With our present knowledge, it is not possible to propose for these tumors other therapeutic measures than those already in use for high grade urothelial malignancies, based on the level of infiltration in the bladder wall. The classic pejorative prognosis of these tumors is contradicted by the favorable evolution in some cases reported in medical literature.
