RESUMO
A 24-year-old Japanese woman was admitted to our hospital in January 2000 with daily diarrhea, abdominal distention, and abdominal pain. Raynaud's phenomenon with erythroderma desquamativum eruptions had been found in 1992. In 1999, small intestinal transillumination showed dilation of the second and third portion of the duodenum. She was diagnosed as amyopathic dermatomyositis because of Gottron's sign despite not having symptoms of myositis, normal serum CPK levels and no histological abnormality by muscle biopsy. In addition, the patient was diagnosed as systemic sclerosis sine scleroderma because Raynaud's phenomenon, leukoma and gastrointestinal dilation were present. Also, antinuclear antibody and anti centromere antibody were positive and anti Scl-70 antibody was dull-positive, despite the absence of scleroderma, extreme edema, and bone resorption. Careful, long term observation will be required because of the splanchnopathy in youth and the complications of systemic sclerosis.
