Erythema Ab Igne Caused By Laptop Computer

Abstract

Erythema ab igne (EAI) represents the stereotype of a modern technology induced disease. Originally produced by repeated exposure of the skin to a heat source, more often because of habits related to the job or personal activities, this condition now tends to occur more frequently, being associated with a variety of modern instruments. The aim of our report is to discuss this strange medical condition with a focus on clinical features, possible confounding differential diagnoses and recommendations for prevention.

Clinical features and etiology of patients with erythema ab igne: A retrospective multicenter study

“…Electric heater, automobile seat heater, open fires, heating pads, steam radiators, laptop computer, hot water bottles, hot water heaters, hot stove, microwave popcorn, and infrared lamps‐like agents had been shown to cause EAI . In our study, the lesions were most frequently seen in the lower legs.…”

“…Although the pathophysiology of EAI is not fully understood, recurrent heat exposure is thought to cause damage to superficial blood vessels, resulting in hemosiderin accumulation and subsequent hyperpigmentation. 1,3,6 Changes in the microscopic level in the skin typically occur due to cumulative and long-term exposure to infrared radiation. Microscopic changes also depend on the type of heat source.…”

“…Generally, nonspecific histopathological findings are detected and skin biopsy is frequently used to exclude other diagnoses. 1,4,5,16,18 In our study, the diagnosis of EAI was made based on the clinical history of the patients, the appearance of the lesions, and the localization of the sites. Histopathological examination was performed to exclude the diseases in the differential diagnosis only in a patient with bullous EAI.…”

“…The most important approach in the treatment of EAI is the elimination of the cause. Occurring abnormal pigmentation of the affected areas can be resolved within months or years; however, hyperpigmentation or scarring may persist . Topical tretinoin and hydroquinone therapy are generally recommended to avoid persistent hyperpigmentation, although no medical treatment is required.…”

“…Erythema ab igne (EAI) is a skin disease characterized by reticular hyperpigmentation due to prolonged and repeated heat exposure. It is frequently seen in the lower extremities and middle‐aged women . Erythema ab igne may be caused by the use of various heat sources such as electric stoves (heater), laptops, and hot water bottles .…”
