L51.21: Toxic epidermal necrolysis [Lyell]: involving 30% or more of body surface

You have a severe skin condition where lesions form.

The immune system is normally supposed to fight and eliminate diseases and foreign substances in the body. This condition causes the immune system to react too strongly to various influences, damaging some cells in different areas of the body. These influences can include certain medicines, pathogens and other diseases.

Other symptoms occur some time before the first lesions appear. These symptoms can include fever and pain in the throat, head or in the muscles.

These are followed by painful sores in the mouth and at the genitals and anus, for example. The eyes can also be inflamed.

Meanwhile, reddish or bluish skin lesions form. Within a short time, the skin lesions spread to extensive redness, on which large blisters form. The blisters burst. The blisters make large areas of the skin peel away. Parts of the affected skin can die off. The skin changes are mainly found on the face and on areas of the skin where the body lies on the bed. However, they can also spread to other parts of the skin. In your case, 30 percent of the skin or more is affected. Internal organs, for example, can also be affected by the condition. This disease makes you severely ill.
