DefinitionThis section has been translated automatically.
Extremely therapy-resistant, eminently chronic and (selectively) very itchy, mostly symmetrically localized, verrucous "variant" of the classic Lichen planus, which occurs particularly in the area of the lower extremities; less frequently on the back of the hand.
A verrucous transformation can also occur secondarily in the case of years of Lichen-planus efflorescence.
EtiopathogenesisThis section has been translated automatically.
S.u. Lichen planus. In most cases, the oversubscribed component is probably the expression of a special form of reaction due to an orthostatic factor.

Clinical featuresThis section has been translated automatically.
Localized or disseminated, rarely in linear arrangement, 0.2-3.0 cm in size, sometimes up to 10 cm in size, coarse, grey-white, also red or reddish-brown, sometimes dirty brown, sharply delimited, soiled papules, plaques, which can conglomerate into large, wart-like foci.
Leading clinical symptom is a very unpleasant, permanent itching, which is described as piercing or piercing. The constant reactive scratching of the lesions may be a triggering factor for the verrucous component of the lichen planus verrucosus. This mechanism is called the itch-scratch-cycle. Sometimes scarring areas are visible in the plaques.
Quite often, triggering factors can be held responsible for the verrucous transformation of the lichen planus. Thus, chronic venous insufficiency as well as constant scratching can be considered as an entertaining trigger factor for the lichen planus verrucosus of the lower leg.
HistologyThis section has been translated automatically.
Image of the lichen planus with striking compact orthohyperkeratosis, with massive irregular epidermal hyperplasia. The infiltrate is differently dense, tending to be rather sparse with a focus on the tips of the reteleases. In contrast to the non-verrucous lichen planus, the verrucous variant may have a relevant number of eosinophil granulocytes. Rarely also plasma cells.

External therapyThis section has been translated automatically.
potent glucocorticoids (e.g. class IV glucocorticoids) under occlusion (2 times/day 2-4 hours).
Alternatively: Vit D3 - analogues under occlusion.
Supplementary: Inject the foci with glucocorticoids such as triamcinolone crystal suspension 10-40 mg (e.g. Volon A): Draw up suspension with 2-4 ml 1% scandicain in a syringe and apply intrafocally.
Supplementary: Consistent wearing of compression bandages in the presence of chronic venous insufficiency.

Progression/forecastThis section has been translated automatically.
Eminently chronic course. The average duration of the disease is 6 years. Complications can develop after years of existence intralesional keratoacanthomas or squamous cell carcinomas (Campanati A et al. 2003).
