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.

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).
