Abstract

Phyllodes tumor of the prostate is rare. We have recently experienced a case of phyllodes tumor of the prostate in a 57-year-old man who complained of urinary retention for 1 year. The epithelial components were positive reactivity for prostate specific antigen. The stromal cells showed nuclear atypia with increased mitotic activity. The tumor was diagnosed as a malignant phyllodes tumor as it invaded into the urinary bladder and rectum, and grew rapidly immediately after operation. We describe the morphological features and immunohistochemical findings of malignant phyllodes tumor and review the literature.
