Abstract
Extraskeletal chondromas are benign soft tissue tumor of hyaline cartilage. These tumors are rare and the pathogenesis is unclear. They are usually involves the hand or feet. We report the case of extraskeletal chondroma arising from subungual region of the finger with nail deformity and review of the literature.
