Abstract:
Primitive neuroectodermal tumor (PNET) is a rare and highly malignant neoplasm composed of small round cells, which frequently occurs in children and adolescents. PNET originating from the prostate is even rarer. We report a case of PNET of the prostate with notalgia and paraplegia as the initial symptoms. Positron emission tomography-computed tomography scanning showed hypodense and hypermetabolism on the prostate; subsequently, we ascertained the diagnosis by transrectal ultrasound-guided biopsy. The patient underwent local vertebral radiotherapy combined with five courses of systematic chemotherapy. Disease progressed after 11 months, and the overall survival was 17 months.
