Osteochondromatosis: A rare clinical condition

Abstract

A case report of multiple hereditary exostosis / osteochondromatosis is presented. Exostosis is a benign cartilaginous lesion. Solitary lesions are called osteochondroma, while the presence of multiple lesions, an autosomal dominantly inherited genetic defect, is called osteochondromatosis. In extremely rare instances they may devolve into a chondrosarcoma, the chances of which are much higher in the presence of multiple lesions. We report a rare case of an eight-year-old girl who presented with multiple swellings arising from the metaphysial regions of the femur, tibia, fibula, and the radius. She was treated conservatively by us, and is currently being monitored regularly for any malignant change.
