Extraskeletal osteosarcoma: an unusual presentation as tarsal tunnel syndrome.
Tarsal tunnel syndrome is a compressive neuropathy caused by intrinsic or extrinsic pressure on the posterior tibial nerve or one of its terminal branches. A mass in association with tarsal tunnel syndrome is most likely a benign tumor or tumor-like condition, although a more malignant tumor must be in the differential diagnosis. We report an unusual case of an extraskeletal osteosarcoma causing tarsal tunnel syndrome.
