Sarcoidosis presenting as cutaneous ulceration, subcutaneous nodules and chronic arthritis.

Subcutaneous nodules and cutaneous ulceration are rare accompaniments of chronic sarcoid arthritis. We report a patient with sarcoidosis who presented with the uncommon combination of chronic arthropathy, subcutaneous nodules and cutaneous ulceration who was initially diagnosed as rheumatoid arthritis (RA). Sarcoidosis should be included in the differential diagnosis of articular disorders that may mimic RA.
