title: Pure primary prostatic osteosarcoma arising in a non-irradiated prostate.
abstract: A 68-year-old man who initially presented with hematuria was found on prostate biopsy to have sarcoma of the prostate with osteogenic features. Radiological examination revealed a locally advanced pelvic mass involving the prostate, seminal vesicles, and rectal wall without metastatic disease. The patient underwent total pelvic exenteration with intraoperative radiotherapy. The tumor was composed of two nodules measuring 7.5 and 4.5 cm involving the prostate, both seminal vesicles, the bladder, rectum, and perirectal fibroadipose tissue. The final diagnosis was osteogenic sarcoma of the prostate.
