ABSTRACT

Sarcomas of the prostate, especially those of stromal origin, are responsible for 0.1- 0.2% of all malignant prostate tumors. Rhabdomyosarcoma is a mesenchymatous tumor of the prostate that does not express CD34 or progesterone and is seen exclusively in infancy. Leiomyosarcomas are the sarcomas that more frequently involve prostate tissue in adults and they express actin and desmin in immunohistochemistry studies. The phyllodes subtype is a rare tumor that has an uncertain malignant potential, but it rapidly develops metastases in the majority of cases and tends to be recurrent.
We present the case of a 79-year-old man that developed a high-grade phyllodes-type prostate sarcoma with unusually rapid and extensive metastasis.
