Acrodermatitis continua suppurativa. moderate infestation of the feet. grouped blisters and isolated pustules (Note: in case of so-called dyshidrotic clinical pictures on hands and feet with regular and intermittent pustules, the diagnosis "dyshidrotic eczema" is unlikely. inflammatory plaques aggregated on individual toes.
Black heel. asymptomatic, self-limited, trauma-induced bleeding into the skin in the heel area, which impressed as a black spot for many weeks. this finding could be completely eliminated by flat ablation of the horny layer with a scalpel (proving an old hematoma).

Furthermore, reddish-brown, partly encrusted, punctiform, older erosions appear in places where water clear vesicles were previously present. Occasionally pinhead-sized, bulging water clear vesicles as well as fine-lamellar scaly deposits. Similar skin lesions are also present on both plantae and the edges of the toes.
Epidermolysis bullosa simplex, Weber-Cockayne. acute, large blister occurring in the area of the heel after light walking. frequent occurrence of blistering after minor trauma within the family. mild form of epidermolysis simplex with blistering as a consequence of relatively minor traumatic stress on hands and feet.
Keratosis palmoplantaris papulosa seu maculosa: Multiple verruciform horn cones persisting since early childhood and partly funnel-shaped defects at the foot of a 52-year-old woman.
Keratosis palmoplantaris papulosa seu maculosa. since childhood persistent, chronically stationary, strong keratinization of the planta pedum with multiple, few millimeters large, wart-like horny cones with rough, scaly surface. central rejection with funnel-shaped defect.
keratosis palmoplantaris papulosa seu maculosa. severe keratosis of the planta pedum in a 26-year-old woman. since early childhood multiple, small, isolated, wart-like horny cones with a rough, scaly surface are visible. a melanocytic nevus is also present on digitus III.
melanoma, malignant, acrolentiginous. irregularly limited, brown-black to black spot localized at the right planta pedum. according to the medical history the asymptomatic skin change has existed for several years. partly regression zones and nodular parts exist.
Melanoma, malignant, amelanotic. 1.5 x 1.6 cm measuring, sharply defined, non-pigmented, white-red tumor with whitish to yellowish, verrucous, partly erosive changed surface on the lower leg of a 70-year-old patient.
Nodular malignant melanoma (amelanotic). 5 months ago first noticed, cherry-sized, slowly size-progressive, superficially completely eroded, moderately shifting, sharply defined nodule with a reddish to skin-colored coloration (right outer ankle of the foot) in an 83-year-old female patient (TD: 5 mm; Clark level IV, pT4b N0 M0; AJCC IIC).
Melanoma, malignant, amelanotic. detail enlargement: Cherry-sized tumor, completely eroded on the surface, with yellowish crusts on the edges, sharply defined.
Melanoma, malignant, amelanotic. sharply defined, largely amelanotic flat knot. on the right side still distinct melanotic pigmentation. also at the upper rim delicate pigmentation.
Plantar fibromatosis: Chronic stationary, subcutaneously located, skin-coloured to brown, approx. 5 x 4 cm large, coarse knot of a 60-year-old man, localised at the Arcus plantaris. 10 years of pressure pain and difficulties in rolling.
Psoriasis palmaris et plantaris. sharply defined plaque with blisters (lower left), rhagades and coarse lamellar scaling on an erythematous ground in the area of the planta. further foci on the lower leg.
psoriasis palmaris et plantaris. hyperkeratotic changes in a 50-year-old office worker, existing for 5-6 years. painful rhaghades persisting for weeks at the edge of the heel, especially after jogging. never blisters or pustules. the inflammatory fringe at the edge of the keratosis is typical (but not proving) for psoriasis. clinical diagnosis "psoriasis plantaris" from this (mono)finding difficult. securing the diagnosis by clinical evidence of psoriasis at the contralateral heel, elbows and palms.
psoriasis palmaris et plantaris. sharply defined, clearly infiltrated, rough plaques with coarsening of the skin field. redness accentuated in the marginal area. extensive (parakeratotic) scaling. this finding is typical of non-pretreated psoriasis plantaris.
psoriasis palmaris et plantaris. dry keratotic plaque type. chronically inpatient psoriasis palmaris et plantaris known for years. massive, flat, extremely horny, rough, yellow-brown plaques in the area of the mechanically stressed areas of the sole of the foot. horn plates already detached at the edges. essential inflammatory phenomena are missing.
