[Osteochondroma. Report of a case with atypical localization and symptomatology].

Abstract

Osteochondroma, the most common benign bone tumor, represents 10-15% of all bone tumors. It can occur frequently as solitary osteocartilagineous exostosis or rarely as hereditary multiple lesions. The most common sites of occurrence are long bones of the lower arm (50%), usually the lower end of the femur and upper end of the tibia. However, involvement of the small hand and foot bones occurs in 10% of cases, pelvis in 5%, scapulae in 4%, and spine in 2%. Symptoms are not very specific. The authors present an atypical case of osteochondroma.
