Acrokeratosis paraneoplastic: the thoracic view shows disseminated, yellowish-brownish keratotic plaques, which condense in the area of the Areolae mamillae as well as centrothoracally in the sternal region; in the sternal region aspect of the seborrhoeic eczema (but the inflammatory component is missing).
Eczema atopic (overview): severe, universal (erythrodermic) atopic eczema. exacerbation phase since about 3 months. patient with rhinitis and conjunctivitis with pollinosis. total IgE >1.000IU.
ILVEN: 5-year-old girl in whom flat and linear plaques in a characteristic arrangement along the Blaschko lines were noticed since the first year of life (not detectable at birth). This bizarre pattern marks the changes as a cutaneous mosaic and thus as a harmlessoma of the skin. For half a year the inflammatory character has been increasing.
dermatitis, seborrhoeic: 58-year-old patient with negative self- and family history of psoriasis. recurrent HV in the seboohoeic zones of the trunk for years. no itching. improvement in summer. multiple, chronically inpatient, figured, borderline, temporarily itching, moderately scaly, clearly borderline hardly elevated plaques.
Urticarial vasculitis. 33-year-old female patient with distinct reduction of the az. 3 weeks of recurrent febrile attacks (CRP and SPA massively increased) and a distinct feeling of illness accompanied by a maculo-papular, moderately itchy exanthema. Histological: Evidence of a leukocytoclastic "small vessel vasculitis". The clinical differentiation from urticaria is possible by marking a persistent efflorescence for several days (marking test). Recurrent and changing arthritis.
Common melanocytic nevus:Symmetrically structured melanocytic compound nevus of junctional and dermal cell nests with basal maturation coveredby papillomatous squamousepithelium. The nests are superficially discontinuously pigmented, accompanied by melanophages. The squamous epithelium is narrowed and with elongated reticules, covered by lamellar hyperkeratosis.
Extension along the hair follicles in strands, here partly neuroid cytomorphology of melanocytes.
Melanoma malignes superficially spreading: pigmentation mark known and growing for years. No subjective complaints. The melanoma grows asymmetrically (no axial symmetry) with irregular pigmentation and depigmentation zones.
