Toasted skin syndrome

Laptops lead to 'toasted skin syndrome'
-----------------------------------------------
Erythema ab igne, also known as laptop thigh, and toasted skin syndrome, is a skin condition caused by long-term exposure to heat (infrared radiation). Overexposure to heat causes a mild red rash that might be described as "blotchy". Prolonged and repeated exposure causes a marked redness and colouring of the skin. Some people may complain of mild itchiness and a burning sensation, but often, unless a change in pigmentation is seen, it can go unnoticed.

Treatment:
-----------------
The source of heat must be removed. If the area is only mildly affected with slight redness, the condition may resolve itself in a few months. If the condition is severe and the skin pigmented and atrophic, resolution is unlikely. In this case, there is a possibility that squamous cell carcinomas may form. If there is a persistent sore that does not heal or a growing lump within the rash, a skin biopsy should be performed to rule out the possibility of skin cancer. Abnormally pigmented skin may persist for years. Treatment with topical tretinoin or laser may improve the appearance.
