title: Malignant phyllodes tumor of the prostate.
abstract: We report a case of malignant phyllodes tumor of the prostate which is the eleventh reported case in the world. Phyllodes tumor of the prostate is extremely rare and histologically resembles mammary phyllodes tumor. Phyllodes tumor of the prostate is classified into benign, borderline and malignant, but health professionals should carefully follow up the borderline cases in case they take a malignant clinical course. This case was the first to be treated by pre- and postoperative radiation therapy. Although the patient had a slight response to radiation therapy, he eventually developed metastasis. Because malignant phyllodes tumor of the prostate is a very aggressive tumor, people with the condition should undergo systemic chemotherapy as adjuvant therapy.
