Arthritis in Melorheostosis-An Uncommon Feature in a Rare Disease

A 53-year-old male developed left knee and left ankle arthritis associated with marked induration of the skin and soft tissues distal to the knees. The left knee was swollen, tender, and with a non-reducible contracture and similarly the left ankle and the subtalar joint were stiff and moderately swollen. In addition, diffuse, bluish, small vascular ectasia, hypertrichosis and skin pigmentation of the affected sites were evident (fig1). These symptoms began 20 years before and the patient had been diagnosed with eosinophilic fasciitis and treated with daily prednisone leading to partial improvement of the symptoms, but not of the knee deformity and soft tissue induration.
