Clinical presentation of index patient. A photograph of the index patient’s left hand is shown (a). Numerous palpable nodules were evident, which had been present since childhood. Multiple hemangiomas spread throughout his body were found, including his right buttock (inset). A radiograph of the left hand showed calcific nodules and lytic lesions of the phalanges, characteristic of enchondromas (b). 3D anterior (upper panel) and posterior (lower panel) reconstruction of a chest CT showed additional osseous lytic lesions (c). Whole-body bone scintigraphy revealed multiple areas of increased radiotracer uptake, suggestive of enchondromatosis (d). Figure is available in color online only.
