Acne Conglobata and Rarer Forms of Acne

Acne conglobata: very severe form of nodulocystic acne in which inflammatory lesions predominate and run together and often form exudates or bleed. Acne conglobata may cause extensive scarring. Acne fulminans: sudden, severe inflammatory reaction which causes deep ulcerations and erosions; may be associated with fever and arthralgia. Acne excoriée: mainly affects young women and is characterised by self-inflicted wounds associated with a psychological or emotional problem. Acne mechanica: caused by pressure, friction or rubbing from clothing. [2] Acne cosmetica: caused by contact comedogenic products with the skin. One study found the link between acne and cosmetics was weak but conceded that it was possible with some products. [3] Chloracne: caused by occupational exposure or military exposure to halogenated hydrocarbons. It presents with many large comedones. [4]
