Advanced chondrosarcoma of the pelvis: A rare case of urinary obstruction

Abstract

Chondrosarcoma is the second most common malignant tumor of the bone with an incidence of 1 in 200.000 per year. Axial skeleton is frequently involved showing poorer oncological outcomes than appendicular one: human pelvis is a site predilection. It is rarely associated to urinary obstruction but according to its localization, it can be frequently linked to compression of pelvic organs as bladder, prostate or bowel. We describe the case of a 52 years old caucasian male with history of advanced pelvic chondrosarcoma and severe hydronephrosis due to total bladder dislocation.
