Poikilodermatomyositis
Abstract
- The authors observed 2 cases of poikilcdermatomyositis who were 16 and l0 years old female. The former visited our dept. due to rashes on the anterior portion of right thigh with 3 months duration. The skin lesion revealed mottled skin pigmentation, telangiectasia, atrophy, and cigarrette paper like wrinklings. On the palpation, hardness and tenderness in the lesion were felt. The latter visited our dept. due to weakness of the right lower extremity for 3years. The skin lesion revealed the same feature as the former but more prominent. Histophthologically, P.V.A. patterns are seen in the both skin lesions. The epidermis shows moderate atrophy of St. malphigi and flattening of reteridges. The dermis is edematous, vascular dilatations, and cellular infiltrations, most of lymphocytes, around the blood vessels. The muscle biopsies for the Quardriceps Femoris sbow Dermatomyositis patterns which the muscle bundles are degenerative changes and many cellular infiltrations, chiefly of lymphocytes, are seen between the muscle bundles. Diagnosis was confirmed by the clinical and histological pictures. These patients were markedly improved by the prednisolone therapy.
