A case of mixed connective tissue disease

Abstract

We report a case of mixed connective tissue disease. A patient, 25-year-old woman, presented Raynaud phenomenon, proximal muscle weakness, sclerodactyly, fever, and diffuse alopeeia. In the serologic examination, antinuclear antibody and anti-RNP antibody were positiv but anti-native DNA antibody was negative. In direct immunofluorescent study of biopsy specimen of the skin, speckled epidermal nuclear staining of IgG and granular deposits of IgM at the dermoepidermal junction were seen: Electromyographic finding of the right deltoid and right gastrocinemius muscle was consistent with myopathy.
