Erythema ab igne (EAI) is a dermatosis characterised by reticulate red-brown pigmentation and telengiectasia resulting from long-term exposure to infrared radiation. It generally occurs in individuals using heating devices in the winter, those who frequently use hot compresses, and those who prefer hot environments. It generally occurs on the feet of women but may also occur on the hips and thighs. A 42-year-old male presented with red-brown spots and blisters on both thighs and behind the legs. He was diagnosed with EAI based on the clinical, historical, and histopathological features presented. Herein we present a case of bullous EAI associated with normochromic normocytic anemia and subclinical hypothyroidism.
