          Abstract

          Erythema ab igne (EAI) is a typical example of an environmental-induced dermatosis secondary to overexposure of a particular part of the skin to heat. Once a familiar entity in the precentral heating era, it seems to be making a comeback with prolonged usage of electronic devices close to the body surface as well as usage of alternative methods of pain relief being sought by patients. We describe a case of a 39-year-old female who presented to our clinic with a mottled reticulate rash on her back after five years of using heating pads for her chronic backache.

          Laptop computer-induced erythema ab igne in a child and review of the literature.

          Jason W. Arnold, Peter Itin (2010)
          We report here the case of a 12-year-old boy with erythema ab igne on his left thigh caused by the use of a laptop computer. This is the youngest of the 10 reported patients with this laptop-induced dermatosis since its first description in 2004. Erythema ab igne is a reticular, pigmented, sometimes telangiectatic dermatosis that is caused by prolonged exposure to a heat or infrared source. In laptop-induced erythema ab igne, the localization on the thighs and asymmetry are characteristic. The heat originates from the optical drive, the battery, or the ventilation fan of the computer.

            Laptop-induced erythema ab igne: Report and review of literature.

            Ryan R. Riahi, Philip R. Cohen (2012)
            Erythema ab igne is an erythematous, reticular hyperpigmentation that results from prolonged thermal radiation exposure insufficient to cause a burn. Historically, lesions were found on individuals exposed to open fires or stoves, but more recently, erythema ab igne has been described in patients using portable electronics devices including laptops. We report a 21-year-old woman who presented with net-like hyperpigmentation on her thighs caused by prolonged laptop use. We also review the literature that describes other individuals with laptop-induced erythema ab igne and discuss the features of this condition.

              Thermal keratoses and squamous cell carcinoma in situ associated with erythema ab igne.

              J Arrington, D Lockman (1979)
              A 60-year-old black woman had a large hyperkeratotic lesion and multiple smaller hyperkeratotic papules and plaques on the lower part of her legs in areas of erythema ab igne. Histologic examination of the largest lesion showed hyperplastic carcinoma in situ and the multiple smaller lesions showed varying degrees of squamous cell atypia and dermal elastosis. Histologically, these lesions were identical to solar-induced atypia, indicating that squamous cell carcinoma arising in erythema ab igne may be biologically similar to actinic carcinoma. Discussed here are clinical and histologic features of the thermal-induced lesions and other types of thermal-induced carcinomas.
