Recently we have experienced a case of CRST syndrome. This syndrome has been defined by four clinical features: (Calcinosis, Raynaud's Phenomenon, Sclerodactylia and Telangiectasia). It has been first reported by Winterbauer in 1964.
The patient, 55 years old (female), was admitted with chief compliant of tumor in the bilateral elbows and knees.
On X-ray examination, there were abnormal calcifications in subcutaneous tissue of these areas. Histologically, the tumors were made from multiply calcified tissues and surrounded by inflammatory cells. In other respects, we recognized sclerodactylia and telangiectasia in the face and anterior chest wall.
On 11th, September, 1979, resection of the tumors was carried out. She is fine after this operation without recurrence for more than six months.
