摘　　要：The present study reports a rare primitive neuroectodermal tumor (PNET) of prostate.A 27-year-old male was admitted to Harbin Medical University Cancer Hospital (Harbin,China) for dysuria and dyschezia. Magnetic resonance imaging (MRI) revealed a large mass thatmay involve the bladder and rectum next to the prostate. Histopathological analysis of biopsyof prostate indicated mesenchymal origin tumor, and immunohistochemistric stainingconfirmed diagnosis of PNET of prostate. En bloc total pelvic exenteration and double barrelsigmoidostomy were performed. Double stomas in the skin incision were used for fecal andurinary diversion, respectively. Short-term outcome is satisfactory, while long-term efficacyremains to be poor. Clinical features of PNET of prostate should be paid much more attentionand radical surgery and adjuvant chemotherapy should be recommended.
