Abstract

Chondromas are benign cartilaginous tumors that are common lesions of the hand. Most chondromas are enchondromas, meaning that they develop within the bone marrow. Periosteal chondroma, in contrast, is a less common, slow-growing, sharply demarcated tumor composed of hyaline cartilage and developed in contact with the periosteum, either within the periosteal membrane or between the periosteum and the bone. We present a case of a periosteal chondroma that involved the metacarpal of the right thumb for 13 years and was associated with pain after blunt trauma. The tumor was successfully treated by marginal resection.
