Acroangiodermatitis. detail from the above figure. 0.2-0.4 cm large, initially isolated, then aggregated, deep red to reddish-livid papules develop from the smallest red (haemorrhagic) spots with a smooth surface, which finally confluent to form large plaques.
Vasculitis, leukocytoclastic (non-IgA-associated). multiple, acute, symmetric, since 2 weeks existing, localized on both lower legs, irregularly distributed, 0.1-0.2 cm large, sharply defined, symptomless, hemorrhagic spots and blisters as well as beginning incrustations.
Larva migrans. linear plaque, subepidermally situated, tortuous, constantly itching gait on the right hollow foot. conspicuously in the area of the gait structures described blister formation.
Sarcoidosis, subcutaneous nodular form:known pulmonary sarcoidosis; skin findings: subcutaneously and cutaneously located nodules and plates which can be easily distinguished from the surrounding area and which slide on the support.
Necrobiosis lipoidica: Discrete finding with slightly hardened plaque and atrophic surface (parchment-like puckering of the skin surface in the centre).
Pyoderma gangraenosum. multiple, chronically progressive, painful, large-area, blue-reddish nodules, partly with polycyclic ulcerations. characteristic is the necrotic ulcer with a painful marginal zone with walllike, undermined margins and dark red, livid erythematous border.
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.
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).
Ulcus cruris arteriosum:Painful arterial leg ulcer of the lower leg and the back of the foot that has been present for 1 year and is continuously growing and sharply defined; proven PAVK in smokers' history and type 2 diabetes; destruction of tendons (arrow markings).
Pemphigoid, bullous. detail enlargement: Multiple, sometimes several cm wide, flaccid blisters with serous content and extensive erosions on the left foot back of a 78-year-old patient.
Angiokeratoma circumscriptum. localized vascular malformation with bizarre blue-black papular and nodular lesions. no symptoms. increasing prominence of the herd in recent years.
Multiple, round, "eczematous" flat, sharply defined ulcerations in an otherwise healthy 27-year-old female patient. CVI, AVK or immunological underlying diseases were not detectable.
