A 63-year-old man reported a 5-year history of skin thickening of the trunk and a 3-week history of dyspnea. Echocardiography revealed diffuse hypokinesis. Skin biopsies obtained from the waist showed thickened dermis with mucin. Myocardial biopsies showed alcian blue-stained tissue between the muscle fibers. The patient was referred to a dermatologist for phototherapy. Cardiomyopathy should be considered in patients with scleredema. Scleredema usually has a good prognosis; however, the mortality risk could be high when accompanied by cardiomyopathy.
