手提電腦引發一個兒童的大腿火激紅斑

最近一期的《兒科學》上報道了一個十二歲的男孩因用手提電腦而引起左大腿火激紅斑。

2004年第一次報道了手提電腦引發的皮炎，到目前為止共有10例報道，這位男孩是他們中最年輕的。

火激紅斑是一種有色素的，斑疹樣的，有時伴有毛細血管擴張的皮炎。它是由於長期接觸過多的熱能或紅外輻射源所致。

手提電腦引發的火激紅斑常常在大腿上，其特點是不對襯性。熱源是光碟驅動器，電池，和電腦的排熱風扇。

Abstract

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.
