Acro-osteolysis occurring in a patient with idiopathic multicentric osteolysis.

The first report of acro-osteolysis occurring in a patient with idiopathic multicentric osteolysis is presented. In addition to lysis of the shafts and tufts of thd distal phalanges, erosions developed in the interphalangeal, metacarpophalangeal, wrist, hip, knee, ankle, and metatarsophalangeal joints. Acroosteolysis can be part of the spectrum of bony erosions present with idiopathic multicentric osteolysis. A modification of a previous classification of idiopathic multicentric osteolysis is presented based upon a review of the literature.
