Dyskeratosis follicularis (Darier's disease).

Acne inversa. Severe clinical, refractory findings in a 52-year-old female patient. Present since the age of 20. Perianal involvement here.

Verrucae vulgares: linearly arranged, broad-based, white-grey, symptomatic papules (Remark: in a moist mucosal environment all cornification processes - whether inflammatory or neoplastic - turn grey-white, the cause is relatively simple: the horny layer stores a lot of water - as can be seen when bathing the palms of the hands for a longer period of time - and thus obtains this opalescent colouring, which is not transparent for the "colour red"; the normal cheek mucosa does not cornify, so it remains transparent, the red colour of the mucosa shimmers through).

Adenoma sebaceum: diffuse distribution of skin-coloured, shiny papules and plaques. conspicuously bizarre telangiectasias, partly present in the papules and in the surrounding area. no folliculitis, no comedones.

Granuloma anulare, classic type . borderline, in the centre skin-coloured, smooth, painless, firm plaque with the formation of an indicated ring shape without scaling over the middle joint of the left middle finger (fingers are predilection sites). no itching.

Verrucae planae juveniles. slightly reddish, partly also brownish and skin-coloured, densely and in places linearly arranged small papules with a matte surface in the face of a 9-year-old female patient. autoinoculation by scratching (Koebner phenomenon). despite extensive findings, a sudden (inexplicable) spontaneous healing occurred after a long-term treatment with a mild keratolytic external therapy (unsuccessful).

Varicella: generalized exanthema; beside an older, already dried vesicle (below) a fresh pustule.

Collagenosis, reactive perforating. detail enlargement: solitary, 0.3-1.3 cm large, red papules with a coarse central horn plug. the smaller papules correspond to an early stage of the disease.

Hirsuties papillaris penis. 45-year-old man has rows of chronically stationary papillary or filiform whitish nodules at the proximal edge of the glans penis at the transition to the sulcus coronarius.

type i neurofibromatosis, peripheral type or classic cutaneous form. since puberty slowly increasing formation of these soft, skin-coloured or slightly brownish, painless papules and nodules. characteristic for neurofibromas are consistency and the bell-button phenomenon (the papules can be pressed into the skin under pressure). on the flanks on both sides large café-au-lait spots up to 8 cm in diameter. the simultaneous detection of several café-au-lait spots secured the clinical diagnosis here.

angiokeratoma of the glans penis. overview image: bluish-livid, hyperkeratotic papules in a linear arrangement at the glans penis near the sulcus coronarius in a 53-year-old, circumcised patient. sporadically there are also smaller, non-keratotic papules at the shaft of the penis. apart from intermittent itching there are no further symptoms. the angiokeratomas have already been lasered once.

Angiokeratoma of the glans penis. multiple, chronically stationary, 0.2-0.4 cm large, blue-red to brownish papules with partly smooth, partly scaly surface in the area of the corona glandis. these are congenital, circumscribed vascular ectasias.
