TLDR Perforating folliculitis is a skin condition with small bumps that may be linked to other diseases and is hard to treat.

A 20-year-old male presented with a continual papular eruption on the abdomen, flanks, and buttocks, diagnosed as perforating folliculitis, a condition characterized by small pigmented papules with keratotic plugs. Histological examination revealed features such as granuloma formation and pseudo-epitheliomatous hyperplasia. The study suggested that perforating folliculitis should be classified among perforating dermatoses, with potential primary forms existing alongside secondary forms associated with other diseases. Various keratolytic treatments were ineffective, and retinoids were not tested. The condition's specificity was debated, with some considering it a major form of Kyrle's disease, which is associated with pruritus and underlying illness. Dyskeratosis was proposed as a potential cause of follicular perforation.
