Presentation, treatment, and outcomes of chondrosarcoma in young adult patients less than age 50: A case series of ten patients.

Abstract: Chondrosarcoma is an aggressive bone tumor typically affecting older adults in the 6th and 7th decade. These tumors often present as painful masses in the pelvis, ribs, and long bones and have certain characteristic features on the imaging leading to the diagnosis. The occurrence of these tumors in the young adult population is a rare condition that is not well described. Often, they may be confused with benign counterparts, enchondroma or osteochondroma, which does not require any treatment and are very common. The aim of this case series was to analyze the patient presentation and radiographic image findings as well as surgical treatment and outcomes of ten young adults with chondrosarcoma over a three-year period. Overall, imaging of these tumors in young adults did not necessarily demonstrate all typical features of chondrosarcomas such as endosteal scalloping, calcifications, lobular growth, and high uptake on whole-body bone scans. One patient in the case series passed away from complications from dedifferentiated chondrosarcoma, and nine patients have recovered with no local recurrence.
