Extraskeletal Osteochondroma Arising on the Plantar Region

Abstract

Extraskeletal osteochondroma is a variant of extraskeletal chondromas that are uncommon soft-tissue cartilaginous tumors. These tumors may undergo extensive enchondral ossification to form an extraskeletal osteochondroma. This report describes the case of a 39-year-old Japanese man with an extraskeletal osteochondroma arising on the plantar aspect of the foot.
