Chondroblastoma in a metatarsal treated with autogenous fibular graft: a case report.

Chondroblastoma is a relatively rare tumor that mimics giant cell tumor and displays a predilection for long bones. In the present report, we describe the case of a benign chondroblastoma localized to the second metatarsal in a 20-year-old male who presented with a 2-year history of painless left foot swelling. Treatment of the tumor involved excision of the second metatarsal with use of an autologous structural fibular bone graft to stabilize the metatarsus and second toe. After 27 months of follow-up, the patient was ambulating well in regular shoes, with no clinical or radiographic evidence of tumor recurrence.
