title: Periosteal chondroma. A review of twenty cases.
abstract: We are reporting on the cases of twenty patients with periosteal chondroma to stress the importance of a proper clinical and radiographic diagnosis of this lesion. Awareness of the features of the lesion helps to prevent overtreatment of this benign condition, because the cytological findings may be ominous. Even the radiographic pattern may be suggestive of malignant disease. Periosteal chondromas apparently arise from under the periosteum of the diaphysis or metaphysis in adolescents and young adults. Close cooperation between the surgeon, the radiologist, and the pathologist is necessary to achieve proper diagnosis and treatment. Marginal excision is usually effective treatment.
