Palindromic Morphea: Multiple Recurrence of Morphea Lesions in a Case of Systemic Sclerosis

We report an unusual scleroderma case. A 45-year-old woman had recurrent morphea lesions over 10 times in 6 years. She had had preceding inactive systemic scleroderma. New morphea lesions developed cyclically on various portions of her body and improved within 2 years. Interestingly, new lesions have developed on once involved skin as well as uninvolved skin. No exacerbation of systemic scleroderma was induced by outbreaks of new morphea lesions. We could not find a similar case in the literature and named it "Palindromic morphea" because of its unique clinical course. D-penicillamine treatment had a limited effect. Minimal oral prednisolone (5 mg/day) completely suppressed the multiple recurrence of the morphea lesions and enhanced improvement of the sclerosis.
