Basal cell carcinoma, cystic. solitary, chronically stationary, growing imperceptibly for 3 years, 0.6 cm in size, sharply defined, bulging, symptomless, brown, smooth lump with bizarre pattern and central vasectasia.

Melanoma, malignant, lentigo-maligna melanoma. asymmetric, multicoloured, reddish-brownish to black, irregularly limited plaque with nodular parts. The diagnosis was confirmed histologically from the nodular black part.

Keratoakanthoma, a coarse node with a central horn plug, growing within 4 weeks.

Keratoacanthoma: Rapidly growing red lump on normal skin with a wall-like raised edge enclosing a central keratotic plug.

Leprosy. leprosy lepromatosa (-LL-): disease pattern with papules and nodules in diffuse distribution that has been continuously developing for many years; loss of eyebrows, partial loss of eyelashes (Alopecia lepromatosa)

Type I leprosy reaction "upgrading reaction": in a patient with Boderline lepromatous leprosy, characterized by an inflammatory flare-up of facial plaques.

Keratoacanthoma: Solitary, 1.5 cm in diameter, spherically bulging, hard, reddish, centrally dented, strongly keratinizing node on the forehead of an 82-year-old patient; the peripheral, wall-like areas of the node are interspersed with telangiectasias and enclose a central, gray-yellow, keratotic plug.

Merkel cell carcinoma: typical smooth red (pigment-free) painless, firm lump with a calotte-shaped growth form and smooth, reflective surface.

Nevus melanocytic common: melanocytic nevus existingsince earliest childhood. No symptoms. No growth.

Leprosy lepromatosa: advanced findings with numerous, almost symmetrically distributed, asymptomatic papules and nodules, no accompanying inflammatory reaction.

Detailed view: The diagnosis "pigmented basal cell carcinoma" is visible at the left margin, where the spatter-like hyperpigmentation is found (accumulation of melanin clods in the tumor parenchyma, caused by the "accompanying proliferation" of melanocytes). At the upper pole local tumor decay and ulceration.

Basal cell carcinoma, nodular. solitary, 1.0 x 1.2 cm large, broad-based, firm, painless nodule, with a shiny, smooth parchment-like surface covered by ectatic, bizarre vessels. Note: There is no follicular structure on the surface of the nodule (compare surrounding skin of the bridge of the nose with the protruding follicles).

Verruca seborrhoica: General view: On the left side of the picture a 10 x 7 mm large, brown-black, broadly basal knot with a verrucous, fissured surface on the forehead of an 81-year-old female patient.

Type I Neurofibromatosis, peripheral type or classic cutaneous form, numerous smaller and larger soft papules and nodules.

Merkel cell carcinoma: Red, painless lump that grows quickly in 2 months and has a smooth, reflective surface.

Merkel cell carcinoma, rough, shifting, non-painful tumour in the cheek area of an elderly patient, growth within 4 months.

Keratoacanthoma: A few months old, initially flat, in the last 2 months strongly progressive in size, coarse knot with a rough edge wall and a blackish (obviously bled into) central horn plug in a 76-year-old man.

Verruca seborrhoica. detail magnification: 10 x 7 mm, non-itching, greyish-brown, broad-based plaque with a verrucous, fissured surface. above the tumour there is an artificially caused erythema.

Leprosy. leprosy lepromatosa (-LL-). papules and nodes in diffuse distribution.
