Acne fulminans is a severe and rare form of inflammatory acne. Lesion severity and subsequent scarring has a negative impact on the patient's quality of life. We conducted a narrative review of the literature on acne fulminans based on a search for relevant English- and Spanish-language articles published in Medline. We included case reports and case series. The main aim was to describe the clinical and demographic characteristics of patients with acne fulminans. A secondary aim was to determine whether quality of life was affected by the site or extent of lesions. We reviewed 91 articles describing 212 cases of acne fulminans. The mean age of the patients (91.94% male) was 16.6 years. A personal and family history of acne vulgaris was reported for 97.63% and 54.90% of patients, respectively. A trigger was identified in 44.79% of cases. The main cause was pharmacologic (96.63%) and the main drug isotretinoin (65.28%). The sites most often affected were the face (89.31%), the posterior trunk (77.86%), and the anterior trunk (74.81%). The predominant disease subtype was acne fulminans with systemic symptoms (59.12%), which were mostly general (97.06%). Systemic corticosteroids were the most widely used treatment (81.03%). The impact of the disease on quality of life was reported for two patients. In conclusion, acne fulminans mainly affects the face and trunk of male adolescents with a history of acne vulgaris. The main subtype was acne fulminans with systemic symptoms, and most patients were treated with systemic corticosteroids. The effect of acne fulminans on quality of life is under-reported.
