ADAMANTINOMA ARISING IN THE DISTAL FIBULA TREATED WITH DISTAL FIBULECTOMY - A CASE-REPORT AND REVIEW OF THE LITERATURE

Adamantinoma is a rare primary bone tumor occurring in the mandible an d the long tubular bones. The diaphysis of the tibia is the most commo n site of extragnathic presentation. Fibular involvement is rare and u sually has coexisting tibial involvement. Adamantinoma arising in the distal fibular metaphysis has not been previously reported. This is a case of a teenage boy presenting with a cystic lesion of the distal fi bula, initially diagnosed and treated as a unicameral bone cyst. Aggre ssive behavior ultimately led to a diagnosis of adamantinoma. He was t reated with distal fibulectomy without surgical reconstruction with go od functional outcome.
