Case report reveals an incidental extraskeletal myxoid chondrosarcoma during hamstring injury, indicating risks of recurrence and need for local control.
A 61-year-old male presented with a left hamstring avulsion and an incidentally discovered gluteal mass on MRI. Surgical excision confirmed extraskeletal myxoid chondrosarcoma (EMC), managed with adjuvant radiation therapy. Serial imaging showed no recurrence or metastasis, though late wound complications required additional intervention. The patient remained free of recurrence or metastasis at 2.5 years postoperatively. This case underscores the importance of thorough imaging review and coordinated care. Recent large series highlight EMC’s indolent but persistent risk for recurrence, and demonstrate that chemotherapy has limited efficacy, emphasizing the need for aggressive local control and long-term management.
