Melanoma, malignant, nodular. 26-year-old woman was diagnosed with an incidental finding on the back of a solitary, coarse, asymmetrical, pearl-like bordered plaque, measuring 8 x 8 mm and increasing for more than one year. The plaque was pigmented brown-black especially at the edges with a whitish-grey centre and central scaly ruffs. Strong grey-blue streaks and massive pigment network break-offs were visible peripherally under reflected light microscopy.

Primary cutaneous anaplastic large cell (CD 30+) lymphoma. Painless, slowly progressive skin ulcer (62-year-old, otherwise healthy woman) which has been present for several months and treated as "pyoderma". Conspicuously raised wall of the ulcer and distinct induration of the reddened edges.

Boils: highly painful, inflammatory, centrally ulcerated, fluctuating lumps.

Keratosis seborhoeic: A slow-growing, broad-based, brown-black nodule that has been present for years; a lateral view shows the knot's sloppy growth pattern particularly well.

Circumscribed rhinophyma: localized phymogenesis of the nose in moderately severe rosacea. Chronic course for several years; 48-year-old woman.

basal cell carcinoma nodular: detail enlargement. nodule with smooth shiny surface. bizarre vascular architecture.

Neurofibroma in Type I Neurofibromatosis: Multiple Neurofibromas

Central-peripheral neurofibromatosis (palmo-plantar neurofibromatosis or type III neurofibromatosis) Chronic inpatient palmo-plantar neurofibromatosis, progressive in childhood; now no longer progressive, soft, skin-colored, painless palmo-plantar nodules and plaques.

Melanoma, malignant, acrolentiginous. Here: amelanotic malignant melanoma: Chronic inpatient tumor in an 80-year-old patient, existing since 2 years, localized at a pressure-exposed site, flat, sharply defined, slightly painful, similar to an ulcer, slightly raised, flat, ulcerated. The diagnosis as primary tumor was made by finding a metastasis. Note: The diagnosis of malignant melanoma in the presented case can only be made histologically. Clinically, at best, a suspected malignant tumor can be made, which must be clarified histologically.

Sebaceous nevus: Formation of a pigmented hidradenoma within the clearly defined, hairless sebaceous nevus.

Merkel cell carcinoma: rapidly growing non-symptomatic nodule, in a 73-year-old female patient

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.

Comedo (giant comedo): approx. 2.0 cm large, firm knot with a black, keratotic centre about 0.3 cm in size.

Hemangioma of the infant. 6-month-old girl (premature birth): Swelling of the left lower lid of a 6-month-old girl (premature birth) existing since the 2nd month of life, progressive in size, flat, blue, soft, not painful, encompassing the whole lower lid.

Cornu cutaneum: Cornu cutaneum that has been in existence for many years, broadly seated, and has been in painful pressure for some time. close-up

lymphoma, cutaneous T-cell lymphoma, large-cell, CD30-positive. detailed view: multiple, chronically dynamic, increasing, non-displaceable, confluent, hemispherical nodules covering a total area of 6 x 6 cm with hard, central, red part and deep, crater-shaped ulceration in a 64-year-old patient. the ulceration is covered with thick, yellowish coatings. the surrounding area of the ulceration is raised, livid-red and partly erosive weeping.

Dermatofibrosarcoma protuberans. solitary, chronically dynamic, continuously growing for 4-5 years, poorly delimitable to the side and depth, woody solid, smooth, bumpy, red node. the lateral depth extension clearly exceeds the protuberant part (iceberg phenomenon).
