Abstract
A boy aged eleven with a solitary chondroma of the right tibia, and angiomata of the skeletal muscle, subcutaneous tissues, and periarticular tissues of the same limb, is considered to be a case of Maffucci's syndrome (dyschondroplasia with angiomata), although there was not the severe deformity encountered in the previously reported cases. There was a secondary atrophy and adiposity of skeletal muscle, and this was attributed to anoxic effects produced by the angiomata.
