Distal tibial osteochondroma causing fibular deformity and deep peroneal nerve entrapment neuropathy: a case report.

Osteochondromas are the most common benign bone tumors, comprising 9% of all bone tumors and 35% of benign bone tumors. They are frequently diagnosed incidentally. Osteochondromas are mostly asymptomatic, but may cause mechanical findings depending on the location and size of the tumor. Rarely, they may originate from the interosseous surface of the tibia and affect the fibula. We report here a case of a rare osteochondroma originating from the distal tibial metaphysis and causing deep peroneal nerve entrapment syndrome with clinical and radiological findings. To our knowledge, this is the first case in the literature.
