Erythema ab igne (EAI) is a cutaneous reaction to heat environment. EAI is a classic example of environmental and occupational dermatosis. Recently, we encountered a case of EAI and share our experience with a brief review of the causes.A 36-year-old woman from rural Karnataka (south India) presented with asymptomatic lesions over the legs since two months. On examination, reticulate hyperpigmented net-like pattern was observed on the lateral aspect of the right and medial aspect of the left leg [ Figure 1]. Lesions were absent over the medial aspect of the right leg and lateral aspect of the left leg. She recalled history of prolonged exposure to heat while cooking in front of an earthen oven with a wood-burning fire on the ground since several years. She used to tie her sari higher up and below the knees was not covered by clothes, a practice often followed by rural Indian women while cooking to avoid soot and fire particles that could damage her clothing. History and clinical examination revealed the diagnosis of EAI.EAI is caused by repeated and prolonged exposure to infrared radiation insufficient to produce a burn.
