The erythema ab igne ( give a wiki. - lat. For, redness of Fire '), also known as Buschke-Hitzemelanose or caloric hyperpigmentation called, is a net-like colored skin redness ( erythema ) caused by a prolonged heat treatment of the skin is caused. Chronic erythema ab igne can develop into a malignant tumor after many years .

description

When erythema ab igne it is not a burning of the skin. The temperatures involved in the range of 43 to 47 ° C are not high enough for this. You are below the threshold of burns. The warmth is perceived as "pleasant" to "barely bearable". In acute cases, the reddening lasts for hours and then usually disappears completely. The erythema ab igne is usually completely painless. Some patients speak of a mild itching or burning sensation. When exposed to chronic heat, the erythema turns brownish. It then becomes irreversible. Telangiectasias , changes in skin pigmentation , superficial flaking and atrophy develop . After several years, chronically irritated skin can be the starting point for skin cancer, squamous cell carcinoma (spinaloma) or Merkel cell carcinoma .

causes

A laptop on your lap can trigger erythema ab igne . Because the heat sources of a laptop are usually arranged on the left, the left leg is typically affected.

Formerly a was erythema ab igne especially in forging , glass blowers and heaters of steam locomotives observed. In bakers and cooks , the underside of the arm is a common occupational disease . This picture has largely changed in modern times. The main causes are hot water bottles , heating pads or electric blankets, notebooks on the lap and incorrectly tempered or regulated seat heating in motor vehicles. In general English literature, erythema ab igne is often referred to as toasted skin syndrome .

The pathophysiology of erythema ab igne is largely unclear. It is believed that infrared radiation causes changes in the elastic fibers of the skin that are similar to those of skin damaged by radiation.

diagnosis

The erythema ab igne can based on the characteristic appearance and matching history are diagnosed. Chemical and toxic hyperpigmentation as well as allergic contact eczema are to be excluded in the differential diagnosis .

treatment

By avoiding the heat source, the pigmentation disorders of the skin can slowly recede again. In many cases, however, this regression is not complete. There have been reports of successful topical treatment with 5-fluorouracil in which the epithelial changes in the skin could be removed.

Medical history

Abraham Buschke (1907)

The erythema ab igne has been known since time immemorial. The first reports from modern times come from Great Britain. The cause here were peat ovens. The German dermatologist Abraham Buschke named the erythema ab igne in 1911 in a work on the influence of light on syphilitic leukodermic heat melanosis . In his honor, the erythema ab igne is also called Buschke heat melanosis today.
