lipoatrophy, localized after glucocorticosteroid injections. general view: 2.5 x 3.0 cm large, circular area with whitish atrophy of the skin and telangiectasia. clear loss of substance of subcutis and fatty tissue. distal of the atrophy a slight swelling in the sense of a lymphatic congestion is visible. the skin changes developed in the course of the last two years, after a single steroid injection into the left knee because of knee problems.
Purpura thrombocytopenic: line shaped (after scratching, as well as after application of a compression bandage) fresh and slightly older skin bleedings (cannot be pushed away diascopically).
Acrodermatitis chronica atrophicans. Clearly visible, flaccid skin atrophy and edematous redness on the right foot in a serologically proven infection with Borrelia bacteria. The patient spends several months every summer in the Black Forest.
Nevus flammeus: congenital, asymmetrically arranged, non-syndromal (no tissue hypertrophy, no orthopedic malposition) large-area (telangiectatic) vascular nevus; characteristic are the scattered borders of the red spots.
Lymphomatoid papulosis: chronic, relapsing, completely asymptomatic clinical picture with multiple, 0.3 - 1.2 cm large, flat, scaly papules and nodules as well as ulcers. 35-year-old otherwise healthy man.
Klippel-Trénaunay syndrome: extensive vascular malformation with extensive nevus flammeus affecting the trunk, the right arm and both legs. No evidence of soft tissue hypertrophy so far. No AV fistulas.
Pemphigoid, bullous. detail enlargement: multiple, originally tight blisters, which have largely emptied and are localized on flat erythema. in some blisters the bladder roof has already completely detached, therefore multiple small erosions and crusts are visible.
Erythema induratum. 52-year-old secretary has been suffering for 3 years from this moderately painful lesion running in relapses. Findings: Clinical examination o.B. Local findings: 10 cm in longitudinal diameter large, firm plaque, interspersed with cutaneous and subcutaneous nodules. In the centre scarring, on the edge deep, poorly healing ulcerations (here crusty evidence).
Necrobiosis lipoidica: different clinical sections. frontal, large, little indurated, slightly reddened plaque with atrophic surface. lateral a 3.5 cm diameter medal-shaped plaque with a slightly marginalized edge.
Pityriasis lichenoides et varioliformis acuta: acutely occurring "colorful" exanthema with papules of varying size, measuring 0.2-0.8 cm, erosions, and encrusted ulcers; linear arrangement of the lesions in places
