[Clinical report of a case of CREST syndrome]

A case of CREST syndrome presenting with marked diffuse calcinosis and prevailing joint involvement is presented by the authors. Diffractometry revealed the presence of calcified hydroxy-apatite crystals within subcutaneous nodules. Scleroderma-like microcirculatory changes with blood flow alterations typical of Raynaud's syndrome were present on capillaroscopy. The authors feel the case to be of interest not only in view of the rare occurrence of the condition but also of the particular extent and severity of the signs and symptoms presented by this patient.
