Acne comedonica: massive formation of comedones in papulopustular acne vulgaris.

Pigmented spindle cell tumor, nevus reed: dark brown to black pigmented plaque, preferably located on the lower leg. The lesion is usually excised under the suspected diagnosis of melanoma. Illustration from the collection of Dr. Michael Hambardzumyan.

Ink spot lentigo: characteristic criteria are sharp demarcation, dark brown-black reticular lines (pigment network), which are interrupted in places within the lesion (dermatoscopic image)

Argyria: localized argyria of the lip region and the oral mucosa.

argyria (detail): localized argyria of the lip region and the oral mucosa. at higher magnification, the irregular, dark metal deposits in the area of the red of the lips are clearly visible (circle). on "normal" lip skin, this color tone is not produced by the horny layer of the skin.

Ulcer of the skin: complete necrosis of the end phalanx in previously known psoriatic systemic scleroderma.

Ecthyma: on both lower legs, disseminated, 0.4-1.0 cm large, painful, sharply defined ulcers covered with black crusts
