A case of scleroderma spectrum disorder with anticentriole antibody and pulmonary hypertension.
We describe the case of a patient with anticentriole antibody-positive scleroderma spectrum disorder (SSD) who developed pulmonary hypertension. A 54-year-old woman had noticed Raynaud's phenomenon and digital ulcers during the winter for the past 10 years. Although sclerodactyly was not present, digital ulcers, swelling of her hands, and phalangeal contracture were observed. An indirect immunofluorescence test revealed anticentriole antibody. Other SSc-specific antoantibodies were negative. An echocardiogram demonstrated that the estimated right ventricular systolic pressure was increased to 51 mmHg. She was diagnosed as SSD with pulmonary hypertension. This is the first case of SSD with anticentriole antibody to develop pulmonary hypertension.
