Y1 - 2019 N1 - T2 - The Color Atlas and Synopsis of Family Medicine, 3e AB - A 50-year-old woman presented with bilateral erythematous lesions on the inner aspects of both of her lower extremities (Figures 209-1 and 209-2). The lesions had begun developing approximately 6 months ago. They became progressively more noticeable but remained localized in the inner aspects of the lower extremities. She mentioned using a hot-water bottle in the area to keep herself warm at night when 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 in the differential diagnosis. A skin biopsy confirmed the diagnosis of erythema ab igne. The patient was advised to discontinue use of the hot-water bottle on the skin. Over the course of 4 months, her skin lesions started to clear with no further intervention.
