Psoriasis pustulosa generalisata: severe clinical picture with fever, arthralgias and considerable disturbance of the general condition; generalized large-area, confluent erythema and plaques with pustules, the shear rate of which is already declining; coarse lamellar, "corneolytic", fatty, scaling (explanation: only the uppermost epidermal layers with the stratum corneum come loose, so that the scale consists only of an extremely thin, translucent, tearable foil; this type of foil-like honing layer detachment is also found in scarlet fever - also called "scarlatiniform scaling").
Psoriasis pustulosa generalisata: in the case of known, previously only discreetly developed psoriasis, suddenly occurring pustular exanthema with fever, arthralgias and severe disturbance of the AZ.
Acne, oil acne. reflected light microscopy: follicular hyperkeratosis, partially with central vellus hair in the area of the lateral lower thorax in a 20-year-old car mechanic.
In a 62-year-old patient with known CLL (chronic lymphocytic leukemia) a sudden eruption of several, slightly painfulpustules occurred. Findings: On erythematous ground grouped and solitary follicular pustules are visible. In the smear of the pustule aureus staphylococcus aureus can be detected in large numbers.
Pustulose, subcorneal. 6-year-old boy with infantile form of the disease. Craniocaudal erupted pustules after fever attack, disseminated over the whole integument. Whole integument almost completely reddened, flat flat infiltrations of the skin with fine lamellar scaling.
Eccema herpeticatum: Sudden appearance of grouped, partially umbilical papules and vesicles on the trunk of a female patient with previously known atopic eczema.
Acne, steroid acne. reflected light microscopy without contact medium (section: jaw angle region in a 30-year-old bodybuilder): multiple, hypertrophic sebaceous gland follicles with central, keratotic plugs within the ostia, hypertrichosis, transparent horny layer due to corticosteroid-induced hypokeratosis, parallel striated distortion of the skin field lines due to increased transepidermal water loss as well as an ectatic subepidermal vascular network without point capillaries (years of abusus of corticosteroids and anabolic steroids).
Psoriasis pustulosa generalisata. eruption of sterile pustules on extensive erythema in the area of the trunk. multiple, partly extensive erosions and whitish macerations. secondary findings are high temperatures, reduced general condition, leucocytosis.
