Acneiform Dermatoses

The document from 1998 discusses acneiform dermatoses, conditions that mimic acne vulgaris but have different causes, often beginning with inflammatory lesions and potentially developing comedones. It highlights that these eruptions are primarily drug-induced, with corticosteroids, anabolic steroids, and other medications being common culprits. Specific conditions such as bodybuilding acne, gram-negative folliculitis, acne necrotica, and acne aestivalis are described, each with unique features and treatments. For instance, bodybuilding acne is linked to anabolic-androgenic steroid use, gram-negative folliculitis arises from long-term antibiotic use and responds to isotretinoin, acne necrotica may respond to systemic antibiotics or isotretinoin with corticosteroids, and acne aestivalis (Mallorca acne) is triggered by sun exposure and may improve with reduced UV exposure or topical treatments like tretinoin. The document stresses the importance of considering patient history and clinical findings for diagnosis and notes that lesions typically resolve after discontinuing the offending drug.
