HistoryThis section has been translated automatically.

Unna, 1894; Kocsard and Ofner, 1966

DefinitionThis section has been translated automatically.

(Frequent) occurring in light-damaged skin, usually little noticed, single or multiple, asymptomatic, harmless, flat or also wart-like elevated, benign neoplasms. People of advanced age. Stukkokeratoses can be scraped off without difficulty and painlessly with the fingernail, whereby only in the case of deeper scratching out a punctiform bleeding area remains. However, they recur in loco. No tendency to malignant degeneration. Note: This is probably a poorly pigmented or non-pigmented variant of verruca seborrhoica.

ManifestationThis section has been translated automatically.

Occurring at the age of 50 and older. No clear gender preference.

LocalizationThis section has been translated automatically.

Extremities, especially distal lower extremities (extensor sides of the lower legs, back and ankles) as well as the back of the hand and forearm extensor sides. The face and trunk are left out.

Clinical featuresThis section has been translated automatically.

Predominantly multiple, 0.3 - 1.5 cm, roundish or oval, flat raised, sharply defined, white, grey or light brown papules and/or plaques.

Rough, dry, whitish or dusty surface.

No subjective symptoms

A flaky leaf can be removed by scratching. Scratch marks in the lesions become whitish in colour.

HistologyThis section has been translated automatically.

The fine tissue structure is identical to the hyperkeratotic type of Verruca seborrhoica with sawtooth papillomatosis and an often massive lamellar hyperkeratosis.

Differential diagnosisThis section has been translated automatically.

Acrokeratosis verruciformis; epidermodysplasia verruciformis; hyperkeratosis lenticularis perstans.

TherapyThis section has been translated automatically.

In case of cosmetic disorder removal with curettage or by desiccation. If necessary, an experiment with vaporization by laser (CO2 or Erbium-YAG laser).

Note(s)This section has been translated automatically.

The term "stucco keratosis" was chosen as a pictorial term because the keratoses sit on the skin like stucco.
