Jeong, Kim, Jeong, Im, Park, and Lee: A Case of CPPD Crystal Deposition Disease in a Patient with Rheumatoid Arthritis and Systemic Sclerosis

Abstract

Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease is an inflammatory arthropathy that is defined by the deposition of CPPD crystals in articular and periarticular structures. CPPD crystal deposition disease has various clinical manifestation patterns ranging from an absence of symptoms to a severely destructive arthropathy. CPPD crystal deposition disease very rare with rheumatoid arthritis or systemic sclerosis. We report a case of CPPD crystal deposition disease combined in a patient with rheumatoid arthritis and systemic sclerosis.
