Malignant degeneration of a lumbar osteochondroma into a chondrosarcoma which mimicked a large retropertioneal mass

We report a case of a lumbar spinal osteochondroma that transformed into a large chondrosarcoma in a 39-year-old male who presented with an abdominal mass and back pain. This mass was also associated with a fracture of the stalk, which on cross-sectional imaging mimicked a mass of retroperitoneal or...

Zusammenfassung:	We report a case of a lumbar spinal osteochondroma that transformed into a large chondrosarcoma in a 39-year-old male who presented with an abdominal mass and back pain. This mass was also associated with a fracture of the stalk, which on cross-sectional imaging mimicked a mass of retroperitoneal origin. The diagnosis of chondrosarcoma transforming from a lumbar osteochondroma became apparent when comparison was made with previous studies.
