A report of a rare phalangeal periosteal chondroma of the foot.

Abstract

Periosteal chondroma is a benign, slow-growing cartilaginous tumor that typically occurs at the metaphysis of long tubular bones beneath the periosteal membrane. A case is presented of a 42-year-old male who developed a firm, tender, uneven mass encircling the lateral, dorsal, and medial aspects of the right second proximal phalanx following a traumatic event. The mass was excised en toto and histopathologic findings are presented.
