Abstract
This chapter reviews both superficial and deep forms of folliculitis as well as disorders of follicular keratinization and the follicular occlusion tetrad (acne conglobata, hidradenitis suppurativa, dissecting cellulitis, and pilonidal sinus). Examples of superficial folliculitis include those due to Staphylococcus aureus or Pseudomonas aeruginosa infections, whereas acne keloidalis and pseudofolliculitis barbae are examples of deep forms. The disorders of follicular keratinization represent a varied group of dermatoses that have in common prominent keratotic follicular plugs. Some of these disorders are reviewed in other chapters, e.g. lichen planopilaris, pityriasis rubra pilaris and keratosis pilaris, while others are discussed here, e.g. lichen spinulosus and erythromelanosis follicularis faciei. Lastly, there are inflammatory disorders that can have a follicular predilection such as GVHD or, in darkly pigmented skin, papular eczema and pityriasis rosea.
