title: Intravascular extension of an osteosarcoma of the pubic bone into periprostatic venous plexus.
abstract: Pelvic osteosarcomas are uncommon but aggressive tumors that can invade the vascular system. We report a case of a 33-year-old man who presented with groin pain and was found to have a chondroblastic osteosarcoma invading the periprostatic venous plexus. Meticulous intraoperative exploration of the pelvis is necessary in such cases to resect tumor completely, thereby maximizing local control and preventing embolic complications.
