Dermatosis IgA-lineare: fresh onset of a previously known linear IgA dermatosis, where disseminated, itchy and painful papules and papulo vesicles are present.
Toxic epidermal necrolysis. 2 weeks after taking Allopurinol in recurrent attacks of gout, itching and redness on the back for the first time, within a few days dramatic worsening of the general condition with several acute, flat, generalized, randomly distributed, sharply defined, red, weeping and painful erosions. Additional findings were multiple, acute, asymmetrically arranged, disseminated, skin-coloured blisters on a flat erythema on the remaining integument.
Herpes simplex recidivans: recurrent, in this case very extensive, multilocular herpes simplex infection in an HIV-infected person at intervals of 6-8 months

Toxic epidermal necrolysis. detailed view of a solitary, acutely occurring, perimamillary, sharply defined, slightly weeping, extensive, erosive detachment of the skin. the sample biopsies showed a vacuum-associated interfacial dermatitis with epidermal keratinocyte necroses.
Dermatitis medusica: In this general view, 3 weeks after the contact event, a solitary, linearly shaped, rough, strongly increased in consistency, flatly elevated, finely lamellar scaling plaque with scabbing in a 50-year-old man is shown. During a Mediterranean holiday, painful punctures on the back caused by contact with a jellyfish were first shown. The tentacles of the cnidarian could only be removed from the back with difficulty, then formation of bleeding at the adhesion sites. Immediately after contact, formation of streaky, pale erythema.
Erythema multiforme: 35-year-old female patient with Z.n. herpes simplex virus infection 4 weeks ago. multiple, acutely occurring, itchy, exanthema, existing for a few days. 0.2-0.7 cm large, sharply defined, firm, red, smooth papules and partly confluent plaques with partly cocardium-shaped aspect and central blister formation.
