Condylomata acuminata: in the 20-year-old patient, these brownish, partly isolated, partly aggregated to large beds of verrucous papules and plaques have existed for about 1/2 year (?).
Melanoma malignant superficially spreading: Exceptionally large, 6.0x4.0 cm in diameter, malignant melanoma of the SSM type with nodular part. No bleeding, no oozing. The patient carefully clothed the melanoma-bearing area when exposed to the sun.
Circumscriptal scleroderma (plaque-type/variant: Atrophodermia idiopathica et progressiva) Survey picture of the trunk: 2 years ago for the first time appeared, since then size progressive, large-area, erythematous-livid to brown, confluent, discreetly indurated spots and plaques in the region of the trunk in a 68-year-old female patient. In the region of the lower abdomen on the right side clearly sclerosed plaques of whitish color with partly distinctly atrophic surface and partly livid margins are found.
Chloasma gravidarum perstans: Chronic stationary, no longer increasing, periorally localized, smooth, brown spots in a 29-year-old woman 14 months after delivery.
Hyperpigmentation, postinflammatory. overview image: Chronic stationary, multiple, disseminated or confluent, brown-red or brownish smooth spots on the lower legs of a 26-year-old patient. The spots developed over a longer period of time from brown-red, verrucous plaques that had developed in the context of a lichen planus verrucosus.
Acanthosis nigricans benigna: blurred brown-black spots and plaques. the plaques are characterized by a slightly sooted, leathery surface. no subjective symptoms.
Auricular appendix: chronically stationary, existing since birth, not growing for many years, without symptoms, sharply defined, firm, smooth, skin-coloured to brownish nodules.
Dermatoliposclerosis. 64-year-old patient with Z.n. fracture of the distal lower leg after skiing accident 10 years ago and consecutive CVI. For years increasing discoloration and hardening of the distal US third. Extensive hyperpigmentation of the skin with coarse increase in consistency. Flat scaly crusts in the center of the skin change. Small fatty tissue proliferations (piezo nodules) on the heel.
Lentigo solaris: multiple, disseminated, a few millimetres to 1.5 cm in size, oval, roundish or bizarrely configured, sharply defined, yellow-brown to dark brown spots on the back of the hand of a 75-year-old man (convertible driver).

Urticaria pigmentosa: about 0.5-1.0cm large, disseminated, oval or round, brownish-red spots. only when rubbed, increased reddening of the spots with accompanying itching. also during warm showers or baths increased reddening and clearly palpable elevation of the lesions.
