Abstract

Prostatic carcinosarcoma (PCS) is an extremely rare malignancy and is reported to have a very poor prognosis. A 77-year-old Japanese male was diagnosed as PCS containing two components, adenocarcinoma and leiomyosarcoma by the immunohistochemical analysis. Cytology was initially useful for the diagnosis. Treatments with androgen ablative and surgical therapies could not improve the patient's life, and he died at 12 months after the first visit.
