Metacarpal solitary osteochondroma—case report of a rare condition
نویسندگان
چکیده
Histologically, osteochondromas are hamartomas developed from endochondral ossification which are coated with a thin cartilage layer [1]. Epidemiologically, these are the most frequent benign tumor, after nonossifying fibromas and metaphyseal lacunae, representing, in the Unni series [2], about 40 % of all benign tumors, and they are located preferentially at the metaphyseal level of long bones. Their location in the hand is extremely rare, except in cases of multiple hereditary exostoses. The following differential diagnoses should be considered: bizarre parosteal osteochondromatous proliferation (Nora's lesion) [3], florid reactive periostitis [4], and turret exostosis [5].
