Alsharif S

Background: Erythema ab igne (EAI) is a localized skin lesion characterized by areas of reticulated erythema and hyperpigmentation. It is caused by prolonged and repeated exposure to infrared radiation.
Methods: We conducted a structured search using online databases to collect case reports and short case series on laptop computer-induced erythema ab igne. We restricted search to those studies involving case reports publication type, but we did not restrict the search by country of publication or publication dates or language.
Results: Records screened were 116, and 94 were excluded through titles and abstract evaluation. Of 22 full-text articles assessed for eligibility, 22 were included in qualitative analysis. Eventually the number of cases analyzed was 22.
There are 22 case reports of laptop induced erythema ab igne from different countries. In these reports, 13 of the 22 patients were females (62%), while 8 of the 22 patients were males (38%). The average age is 23.5 years. The majority of the cases located on the thighs. The duration of laptop exposure ranged from two weeks to two years.
Conclusion: Laptop computer induced erythema ab igne is increasing in the last years. One of the important questions in evaluation erythema ab igne a patient is about the history of prolongs laptop exposure. We recommend awareness programs development in the future to laptop users about this condition and advise them to avoid placing laptops on their body for prolonged periods of time and direct them to place laptops on a solid barrier.
