This chapter discusses the epidemiology, pathogenesis, etiology, differential diagnosis, and laboratory investigations of pseudofolliculitis barbae and acne keloidalis nuchae. Pseudofolliculitis barbae (PFB) is an inflammatory disorder characterized by papules and pustules in the beard area. It represents a foreign-body inflammatory response to ingrown hairs, and the prevalence is reported to be between 45% and 83% in black men. Acne keloidalis nuchae (AKN) is a chronic inflammatory follicular disorder of the occipital scalp and posterior neck that primarily affects men of African descent. It was first described by Kaposi in 1869 and has since been referred to by various names including dermatitis papillaris capillitii and folliculitis keloidalis. Especially in severe cases, AKN is associated with considerable psychological effects and impaired quality of life.
