Brief Report

Abstract: We report a case of a 65-year-old man who developed an asymptomatic bluish spot that affected the flank and left lumbar region with the onset 10 years prior. He had a history of diffuse systemic sclerosis with anti-Scl-70–positive antibodies. The appearance of the skin lesion coincided with the onset of his disease. The skin biopsy was consistent with the diagnosis of acquired dermal melanocytosis. The relationship between the appearance of acquired pigmented macules and spots and systemic sclerosis has been known for years, although it is an infrequent finding.
