Y1 - 2013 N1 - T2 - The Color Atlas of Family Medicine, 2e AB - A 50-year-old woman presented to the office with bilateral erythematous lesions on the inner aspects of both of her lower extremities (Figures 200-1 and 200-2). The lesions started developing for the past 6 months. They became progressively more noticeable but stayed localized in the inner aspects of the lower extremities. She mentioned that she was using a hot-water bottle in the area involved to keep her warm at night when she was sleeping in bed. Although our working clinical diagnosis was erythema ab igne, clinical entities such as livedo reticularis, poikiloderma atrophicans vasculare, and acanthosis nigricans were also considered in the differential diagnosis. A skin biopsy was performed and confirmed the diagnosis of erythema ab igne. The patient was advised to abandon the hot-water bottle application to the skin. Over the course of 4 months her skin lesions started to clear with no further intervention.
