Isotretinoin treatment for acne can lead to inflammatory flare-ups or an aggravation, occasionally leading to acne fulminans. The purpose of this work was to examine our cases and to propose a classification system for management. ⋯ Acne fuminans is exceptional in patients taking isotretinoin compared with the number of patients treated. Clinicians should nevertheless be aware of the risk in order to make the diagnosis and provide appropriate care.
