We report two cases with long-standing systemic lupus erythematosus (SLE) who developed widespread calcification in subcutaneous tissue and peri-articular structures. To our knowledge only 26 case reports have appeared concerning this abnormality in SLE. However, there has been no report of calcification in an SLE patient in the literature of orthopaedic surgery. The calcifications of the forearm were marginally removed because of pain surrounding them. X-ray analysis revealed that the calcification was made of pure calcium phosphate.
