Multicentric carpotarsal osteolysis syndrome: long-term follow-up of three patients.

Multicentric carpotarsal osteolysis (MCTO) is a rare skeletal disorder characterized by progressive carpal and tarsal destruction. The upper and lower limbs may be involved, leading to deformities and joint limitation. These anatomic features may be associated with progressive renal failure. The radiographs obtained during childhood showed a carpal and tarsal osteolysis and an asymmetrical involvement. Here, we report on the long-term clinical and radiological findings of three patients with skeletal manifestations of MCTO.
