Abstract

Localized scleroderma (Morphea) is a rare fibrosing disorder of the skin. There are several subtypes. In adult, the circumscribed and generalized subtypes are predominant. The skin lesions present as the plaque on the trunk and extremities. Differential diagnosis includes atrophoderma of Pasini and Perini and systemic sclerosis. We report a case of  57 year-old-woman who initially presents with multiple asymptomatic sclerotic plaques on the trunk, abdomen, both forearms and legs without systemic symptoms. The clinical presentation and histopathologic findings support the diagnosis of morphea. The histopathology shows unusal dense inflammatory reaction with many plasma cells infiltrating the nerve. Therefore, the patient is diagnosed as “Morphea with plasma cell neuritis.”
