Acne keloidalis nuchae. 7-year-old patient with multiple erythematous papules and nodules in the neck of a 31-year-old patient.

Pilomatrixoma: Slowly growing, flat, protruding, painless lump that has been observed for 1 year.

Lymphogranuloma inguinale: Abscessing lymphadenitis of the groin (Bubo). 32-year-old patient (stage II of lymphogranuloma inguinale).

Keratosis seborrhoic (papillomatous type)

Boils: painful, highly inflammatory, bulging elastic lump.

Folliculitis profunda. solitary, acute, since 4 weeks existing, 1.2 cm large, sharply definable, firm, moderately pressure dolent, red, smooth lump.

Complicative basal cell carcinoma with complete destruction of the auricle and the external auditory canal. Here, it is impressive as a crater-shaped ulcer. Typical is the raised, shiny rim.

type i neurofibromatosis, peripheral type or classic cutaneous form. numerous smaller and larger soft, predominantly pigmented, practical nodules and nodules. in the larger nodules the so-called "bell-button phenomenon" can be detected. the palpating finger penetrates the deep dermis as if through a fascial gap. few café-au-lait spots. papules and nodules. only isolated rather discreet café-au-lait spots.

blue nevus. blue-black, coarse, sharply defined, calotte-shaped node with a smooth, like polished, shiny surface. in addition, hairs run through the node. follicle ostia funnel-like indented. especially the detection of hairs in the node area speaks against malignancy (DD: nodular malignant melanoma), because the tumor growth does not infiltrate and destroy the hair follicles.

Hidradenitis suppurativa. Severe acne conglobata with hidradenitis suppurativa.

Blue nevus. reflected light microscopy, deep black pigmentation, preserved surface relief.

Acne, keloid acne. Acne vulgaris cured with scar keloids.

Keloids in dark skin: Training on pre-existing folliculitis.

Melanoma, malignant, superficially spreading. 2.0 x 1.4 cm large, brown-black to black plaque with nodular parts and irregular borders on clearly sun-tanned skin. Within the plaque two smaller, reddish-brown areas are also impressive. The lesion has occasionally bled in the history (trace of blood when drying).

Erythroplasia. erythroplasia existing for years with transition to an invasive penis carcinoma. clearly recognizable "cloverleaf-like" progression zones of the carcinoma.

basal cell carcinoma nodular: centrally ulcerated basal cell carcinoma. the diagnosis is recognizable by the marginal, glassy nodular structures. the centre of the nodule is overlaid by an adherent haemorrhagic crust and thus cannot be assessed diagnostically.

Prurigo nodularis: Condition before and after 8 months of Dupilumab therapy (image varied and taken from: Wieser JK et al. 2020)
