title: Carcinosarcoma of bladder. Evaluation by electron microscopy and immunohistochemistry.
abstract: A case of carcinosarcoma of the urinary bladder characterized by electron microscopy and immunohistochemistry is described. The use of these studies in poorly differentiated bladder neoplasms and in suspected cases of carcinosarcoma is encouraged. Increased accuracy in characterizing these tumors will permit a better understanding of their natural history and response to therapy.
