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.
