EtiopathogenesisThis section has been translated automatically.
ManifestationThis section has been translated automatically.
Mainly in children and adolescents; less frequently in early adulthood.
LocalizationThis section has been translated automatically.
Clinical featuresThis section has been translated automatically.
Flat, raised, asymptomatic, roundish or polygonal, light brown or somewhat reddish, slightly consistent, solitary papules, which also merge into small plaques, with a dull surface. The small, non-follicular elevations with their frosted surface are prominent, especially in laterally incident light. They are predominantly irregularly scattered. Inflammatory reddening of the warts often signals immunologic rejection reactions in the wart parenchyma.
Often, however, a linear arrangement (induced by inoculating scratching effects - Köbner phenomenon) can be found. Caused by the same type of virus, plane warts are found on the back of the hand of adolescents or adults (so-called intermediate warts).
HistologyThis section has been translated automatically.
Differential diagnosisThis section has been translated automatically.
Lichen planus: polygonal structure, itching, surface shiny, rarely in the facial area
Lichen nitidus: comparable with Lichen planus
Verruca seborrhoica: no eruptive occurrence, surface matt brown, never shiny
Milia: whitish, small globular, firm consistency, deep set.
Syringomas: in principle syringomas can occur on all parts of the body surface, especially when they are eruptive. Preferably they are found on the lower eyelids, less frequently on the upper eyelids (eyelid syringoma). Further on the neck, chest, axillary folds, groin, vulva/scrotum rarely on the extremities. Especially in adults.
General therapyThis section has been translated automatically.
External therapyThis section has been translated automatically.
- Apply keratolysis with ointment containing vitamin A acid (e.g. Cordes VAS, Isotrex, Aknemycin plus) 1-2 times/day lesionally. In case of burning and reddening of the facial skin reduce to 1 time a day. Cave! Do not use during pregnancy or while breastfeeding.
- Possibly in combination with UV-radiation. Cave! Reduced average erythema dose. Further keratolysis e.g. with 1-5% salicylic acid.
- Successes with 5% Imiquimod cream (e.g. Aldara) applied 3-4 times/week overnight (therapy duration: 3-4 weeks) are described (off-label use!).
- In individual cases the use of photodynamic therapy is just as successful.

Case report(s)This section has been translated automatically.
- A sixteen-year-old girl presented with extensive flat juvenile warts on her forehead and cheeks. She was informed about her clinical picture. Subsequently, a local therapy with a combination preparation (erythromycin/tretinoin) followed. The therapy was indicated as follows: dab the lesions with the solution 3 times a week. The patient initially noticed an inflammatory reaction with a slight burning sensation of the treated skin areas. Within three weeks the warts healed completely. The patient remained recurrence-free in the following period.
- A 35-year-old patient reported surprisingly developed brownish spots on the right cheek. They were limited to the right cheek only, about 20-30, disseminated brown and red, 0.2-0.4 cm large spots and flat plaques with a slightly rough surface. No itching. The treatment was performed as before. After a mild inflammatory treatment reaction with a slight burning sensation, the flat warts healed completely within 4 weeks. The patient remained recurrence-free in the following period.
