A young black man with sickle cell disease with recurrent painful vasoocclusive crises developed at 16 years of age a rapid disabling polyarticular chondrolysis leading to a bilateral hip arthroplasty in 1 year. Light microscopy showed erosion and chondrocyte loss with deep clones in the cartilage and congested vessels with extravasation of red blood cells and mononuclear cells in the synovium. Electron microscopy of the synovium disclosed partially occluded blood vessels and phagocytic cells containing red blood cell debris and crystalline hemoglobin-like material. These observations suggest a role for the phagocytic cells in the joint destruction.
