Lichen planus follicularis L66.10

Variant of lichen planus linked to the hair follicles. The disease can occur ubiquitously, but manifests itself preferentially in the neck region and on the capillitium(lichen planus follicularis capillitii). In case of conically pointed follicular hyperkeratosis, it is also called lichen planus acuminatus (lichen ruber acuminatus) (see Fig.).

The occurrence of lichen planus follicularis on the trunk with lichen planus of the main hair (with pseuopelade condition) as well as dystrophic nail changes is also called Graham-Little syndrome.

Occurring in middle age, women are more frequently affected than men.

Occurs mainly on the capillitium. More rarely, the upper trunk, extremities in joint bends, neck, inner thighs or sacral region are affected. S.a.u. Lichen planus follicularis capillitii.

Diffusely distributed over a larger area, pinhead-sized, follicular, delicately to strongly red colored, ruffle-like erythema arranged around the hair follicle, which gives way in the course of months to 0.1-0.2 cm large, reddened papules with pointed hyperkeratosis without central hair. Older burnt areas show an atrophically scarred, smooth reflecting surface without erythema or follicular structures.

Dense adnexotropic perifollicular lymphocytic infiltrate. Vacuolar degeneration of the basal, adnexal keratinocytes. Acanthosis of the follicular epithelium with amphora-like widening of the excretory duct. In this case, hair structures are often no longer detectable, but only ortho- and parakeratotic horn masses.

Lichen planopilaris (LPP) as a partial symptom of keratosis pilaris

Tuberculosis cutis lichenoides: Very rare clinical picture; symmetrically arranged, disseminated or also grouped, always follicular or perifollicular, pointed conical, yellow-brown, reddish or skin-colored, lichenoid papules, sometimes solitary, sometimes confluent.

Pityriasis rubra pilaris (pityriasis rubra pilaris type 1/classical form): extensive, pityriasiform, often marginal, sharply defined, follicular erythema, also lichenified papules or plaques on the capillitium, face (especially eyebrows, nasolabial folds), also on the trunk.

Keratosis follicularis

Ulerythema ophryogenes.

Glucocorticoid ointments 1-2 times/day on the capillitium. S.u. Lichen planus follicularis capillitii.

According to the Lichen planus.

Quoad sanationem bad. Years of chronically creeping progress.

The lichen planus follicularis can be nosologically distinguished from the lichen planopilaris, which is etiopathogenetically more likely to be counted among the follicular cornification disorders (variant of keratosis follicularis). To what extent the Lassueur-Graham-Little syndrome can be classified as a variant of lichen planus remains unclear at present.
