手提电脑引发一个儿童的大腿火激红斑
JoshuaChow (2010-10-15 14:44:30) 评论 (1)最近一期的《儿科学》上报道了一个十二岁的男孩因用手提电脑而引起左大腿火激红斑。
2004年第一次报道了手提电脑引发的皮炎，到目前为止共有10例报道，这位男孩是他们中最年轻的。
火激红斑是一种有色素的，斑疹样的，有时伴有毛细血管扩张的皮炎。它是由于长期接触过多的热能或红外辐射源所致。
手提电脑引发的火激红斑常常在大腿上，其特点是不对衬性。热源是光碟驱动器，电池，和电脑的排热风扇。

Laptop Computer-Induced Erythema ab Igne in a Child and Review of the Literature.
Department of Dermatology, University Hospital Basel, Basel, Switzerland.
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.
