EtiopathogenesisThis section has been translated automatically.
The genesis of lichen striatus is still a matter of debate. Obviously, only single keratinocyte clones become diseased. Frequently, the first manifestation occurs after a viral infection.
Intrafamilial clustering has also been reported.
Currently, it is assumed that a new antigen is expressed on the keratinocytes of a clone in the course of the infection, which then leads to a local inflammatory reaction.
ManifestationThis section has been translated automatically.
Occurs mainly in children and young people.
LocalizationThis section has been translated automatically.
Asymmetrical: mainly arms, legs (less often: neck or trunk).
Clinical featuresThis section has been translated automatically.
Small reddish, usually less symptomatic, lichenoid, psoriasiform or eczematous flat papules confluent to a reddish, 0.5 - 2.0 cm wide, possibly extending over the entire length of the limb (see also ILVEN). After regression (experience shows that skin changes persist for years), long-term post-inflammatory hypo- and hyperpigmentation may be detectable. Sometimes several stripes are affected in the sense of a systematization. If the stripes end at fingers or toes, nail dystrophy may also be present.
HistologyThis section has been translated automatically.
The hsitological picture is non-specific. Evidence includes images of interface dermatitis with epidermal hyperplasia, circumscribed parakeratosis, single dyskeratotic cells scattered throughout the epithelial band. Mild perivascular lymphocytic infiltrate with minor exocytosis as well as mild spongiosis.
Differential diagnosisThis section has been translated automatically.
ILVEN: ILVEN is not seen as a differential diagnosis, since lichen striatus is considered by many to be a variant of ILVEN, or both clinical pictures are to be subsumed under the designation"Blaschko-linear inflammatory dermatoses".
Note: The term "Blaschkitis" (Grosshans) is probably synonymous with lichens striatus in adults.
Nevus verrucosus unius lateralis: The inflammatory component is absent in this clinical picture, which is also aligned in the Blaschko lines.
Lichen planus linearis (histologic workup).
Linear psoriasis (histological clarification).
TherapyThis section has been translated automatically.
Progression/forecastThis section has been translated automatically.
Formation in 2 to 4 weeks, regression in a period of about 3 months, possibly up to a year, but persistence for years is also possible. Recurrences after healing can occur (as with ILVEN) (see also comments on Blaschko-linear inflammatory dermatoses).
