follicular: when lesions are very evenly or regularly spaced, it implies that they correspond to some anatomic unit e.g. hair follicles, thought this is not always the case (e.g. lichen nitidus is very evenly spaced and yet it is in no way follicular)
Spiny follicular papules:
| • | keratosis pilaris/ lichen spinulosus |
| • | lichen planopilaris (follicular LP) |
| • | perforating folliculitis |
|
More "follicular" entities:
| • | folliculitis (bacterial, pityrosporum, hot tub) |
| • | disseminate and recurrent infundibular folliculitis (not hyperkeratotic) |
| • | juxtaclavicular beaded lines |
