- * * *A rare disorder characterized by hamartomatous proliferation of cartilage in the metaphyses of several bones, most commonly of the hands and feet, causing distorted growth in length and pathological fractures; chondrosarcoma may develop. When e. is associated with hemangiomas in the cutaneous or visceral regions, the condition is called Maffucci syndrome. Most cases are sporadic but a few instances demonstrate autosomal dominant inheritance with reduced penetrance. SYN: asymmetric chondrodystrophy, dyschondroplasia, hereditary deforming chondrodystrophy (2), Ollier disease.
