Questions raised by a case of adult-onset linear nodular scleroderma.

Morphea presenting clinically with nodular or keloidal skin changes is extremely rare. Nodular scleroderma or keloidal morphea presenting in a linear distribution is even more uncommon. We present an otherwise healthy young woman with unilateral, linear, nodular scleroderma and review the somewhat confounding earlier literature in this area. To date, this young woman's skin changes have proven refractory to oral hydroxychloroquine and ultraviolet A1 phototherapy. Several aspects of this case including the patient's family history of Raynaud disease, her nodular sclerodermatous skin lesions, and the presence of U1RNP autoantibodies raised concern about her management with respect to future risk of developing systemic sclerosis.
