ABSTRACT
Acneiform eruptions are skin conditions that resemble acne. The extent to which
an eruption resembles acne depends on the clinician’s aptitude and experience.
Misclassification of distinct clinical entities such as gram-negative folliculitis,
pseudofolliculitis barbae, acne fulminans, and rosacea fulminans, renamed so by
Plewig et al. in 1992 (1), is reviewed in other chapters.
