A Case Report of an Interesting Erythema

Abstract

Erythema ab igne (EAI) is a cutaneous condition characterized by reticular hyperpigmentation resulting from chronic low-grade heat exposure. This case report presents a 30-year-old female with map-like skin lesions on her legs, initially misdiagnosed as livedo reticularis and vasculitis. A detailed history revealed prolonged use of an electric heater, leading to the diagnosis of Erythema ab igne. The lesions resolved spontaneously after heat source elimination. This case highlights the importance of considering Erythema ab igne in the differential diagnosis of reticular skin lesions, especially in patients with a history of heat exposure. Early recognition can prevent unnecessary investigations and alleviate patient anxiety.
