artifacts. few partially excoriated papules in the sense of scratch artifacts on the breasts of a 35-year-old woman. the patient denies the artifact component. rapid healing under bandages (diagnostically almost proving artificial mechanism).
Pemphigoid, bullous. not quite fresh episode in a 65-year-old patient with known bullous pemphigoid. reasons for the episode activity unclear (therapy errors?). maximum exacerbated clinical picture with multiple, 0.5-10 cm large, red itchy plaques and different sized marginal blisters.
psoriasis vulgaris. treated psoriasis vulgaris. the previously existing typical psoriatic plaques are replaced by red spots with marginal hyperpigmentation. the treatment was carried out locally with dithranol [cignolin]. scaling no longer present. the brewing discoloration of the lesional surroundings are reversible discolorations of the nromal skin by diathranol. the diagnosis "psoriasis" is doubtless due to the known anamnesis.
Lymphoma, cutaneous B-cell lymphoma, marginal zone lymphoma. Detailed picture: red, surface smooth papules and plaques in a 59-year-old patient. No scratch excoriations, no scaling, no pruritus.
tinea pedum. dyshidrosiform tinea pedum in a 48-year-old athlete, existing for about 12 months. multiple, itchy, cloudy blisters, healing under scaly crust formation, especially in the arch of the foot. the first interdigital space shows strong macerations, which are only partially visible here.
Acne papulopustulosa: Multiple, chronically dynamic, disseminated, follicle-bound, 2-8 mm large, inflammatory, red papules and papulopustules and comedones on the back of a 19-year-old man.
eczema atopic (overview): extensive reddening of the palm. hyperlinearity. disseminated erosions. lichenified eczema foci in the area of the wrist (DD psoriasis palmoplantaris). for further explanations see next figure.
Malasseziafolliculitis: Detail magnification: Disseminated, follicle-bound, inflammatory, 0.5-3 mm papules and papulopustules on the back of a 66-year-old female patient
Gingivostomatitis, chronic. chronic dynamic, variable, 1.4 cm large, dolent, bizarrely configured ulcer in a 64-year-old female patient with Huntington's disease. development due to ulcerative inflammation at the left lateral edge of the tongue. massive plaque accumulation and sharp-edged incisal and occlusal surfaces have promoted the inflammatory process.
Basal cell carcinoma nodular: Nodule existing for several years, completely without symptoms, size: 2.5 x 3.0 cm. sharply defined. 73-year-old patient. note the bizarre peripheral vessels.
