Osteochondromas Around the Ankle

Abstract

An osteochondroma or exostosis is the most common benign bone tumor, and it is commonly localized in the metaphyses of the long tubular bones. Lesions are rarely localized around the ankle. We present a case series with osteochondroma around the ankle. All of the patients presented with a mass around the ankle. In these three cases, the masses were symptomatic, and in one patient it caused a deformity. Osteochondroma was suspected after physical examination and radiologic evaluation. After preoperative work-up, diagnosis, and exhaustion of conservative care, a plan for surgical excision was presented to each patient. Histopathologic evaluations confirmed the diagnosis of osteochondroma. The patients have been discharged without any complications or symptoms during clinical follow-up.
