HistoryThis section has been translated automatically.
DefinitionThis section has been translated automatically.
Rare, eminently chronic inflammatory skin disease of unclear etiology characterized by hyperkeratotic, considerably pruritic papules, plaques and excoriations. Variant of lichen planus verrucosus? The first describer Moritz Kaposi described the clinical picture under the names: Lichen ruber acuminatus and Lichen ruber planus and thus created more confusion than a clear definition of the clinical picture.

EtiopathogenesisThis section has been translated automatically.
Unclear, variant of Lichen planus or hyperkeratosis follicularis et parafollicularis in cutem penetrans is discussed. A coincidence with anaplastic lymphoma has been described (single case report). Furthermore, infections (hepatitides, glomerulonephritides, tuberculosis) were discussed as triggers.
ManifestationThis section has been translated automatically.
Usually occurring around the age of 20 or 50; but in principle always possible (two-peaked incidence maximum curve). The clinical picture is also described for children.
Men are slightly more frequently affected than women (2:1?).
LocalizationThis section has been translated automatically.
Usually spread, starting from a focal point, to large parts of the integument; trunk and extensor sides of the extremities are preferred.
Clinical featuresThis section has been translated automatically.
Generalized, hyperkeratotic, reddish-brown pruritic, lichenoid papules that confluence into linear and reticular formations, rarely into psoriasiform plaques.
Involvement of oral mucosa ( aphthae, laryngitis) and eyes (keratoconjunctivitis, synechiae formation) possible.
Not rare are palmoplantar keratoses. Furthermore, nail changes (distended hyperkeratotic nail fold, increased curvature of the nail plate).
HistologyThis section has been translated automatically.
Differential diagnosisThis section has been translated automatically.
External therapyThis section has been translated automatically.
Usually complete resistance to local therapeutic agents. Temporary improvement can be achieved with 5-10% urea-containing external agents (e.g. R102, basodexan ointment). Glucocorticoids lead to a temporary improvement.
Alternative: Vitamin A acid ointment/cream (e.g. Cordes VAS).
Alternative: Tacrolimus ointment.
Radiation therapyThis section has been translated automatically.
Internal therapyThis section has been translated automatically.
Retinoids: Acitretin (Neotigason) initial 0.5 mg/kg bw/day, maintenance therapy according to clinic. Possibly combination of PUVA therapy and retinoids according to RePUVA therapy. A combination of acitretin and methotrexate has also proved successful in one individual case (Li AW et al. 2017).
A positive response to an Efalizumab therapy was described as an individual case.
Note(s)This section has been translated automatically.
The entity of this disease described since 1895 by Kaposi is still controversial. Most authors assume that it is a variant of lichen planus, especially since neither histologically nor immunohistologically clear differences are recognizable.
