Candidoses: Female, 62 J. Candida submammary under long-term steroid-containing local therapy of an inverse psoriasis; note the marginal satellite nodules.
Nummular Dermatitis: Multiple, reddened, confluent, roundish or bizarrely configured plaques with weeping yellowish crusts on the back of a 76-year-old female patient.
basal cell carcinoma (overview): basal cell carcinoma pigmented. superficial (superficial), multi-segmental, symptomless, partly smooth, partly scaly plaque. arrows mark the pigmented nodular structure in the marginal area. encircles the prominent marginal structure in the "depigmented" part of the tumor. differential diagnosis excludes a malignant melanoma of the SSM type.
Generalized cGVHD: generalized, lichenoid, only moderately itchy, exanthema with hyperpigmentation, occurring about 2 years after stem cell transplantation.
parapsoriasis en plaques, benign small hereditary form. 55-year-old patient with small spotted parapsoriasis en plaques (also called chronic superficial dermatitis). the distribution pattern (fingerprint dermatosis) in the longitudinal direction of the skin tension lines is almost diagnostic. occasionally slight itching (mostly in the winter months). in summer (after sea vacation) almost healed. histology is often not conclusive.
Scabies:explanatory presentation; chronic (existing for months) generalized, "eczematous", enormously itchy disease pattern with rough papules in the shape of a duct (here marked by black lines), encircling a chronically eczematized skin area without detectable duct structures.)

Special form: Mycosis fungoides follikulotrope: 10-year-old girl with generalized folliculotropic Mycosis fungoides. foudroyant course of the disease which made a stem cell transplantation necessary.
Erythema gyratum repens: Detail of the rim area of the ring structure. clearly palpable (like a wet wool thread) rim area with raised, inwardly directed ruffle. striking "multizonality" with a second only discretely visible inner ring formation.
Basal cell carcinoma superficial: Slowly growing, symptom-free plaque with adherent white scales that has been present for several years; a shiny marginal structure is visible on the left margin.
Graft-versus-Host-Disease, chronic. 56 years old patient with z.n. bone marrow transplantation 2 years ago. since 1 year increasing hardening of the skin. poikilodermatic picture with extensive whitish irritations, reticular hyperpigmentation and bizarre red spots. atrophic (parchment-like) surface epithelium with fine desquamation.
