A Practice Approach to Acne Fulminans in Adolescents.

Abstract

Acne fulminans (AF) is a severe form of inflammatory acne commonly associated with adolescents. It is characterized by an abrupt onset of painful nodules and plaques and can progress to suppurative, ulcerative, and hemorrhagic lesions. AF can be associated with systemic symptoms such as fever, arthralgia, and bone pain. The etiology of AF is unknown but it has been linked to the use of certain medications and has been rarely found in autoinflammatory syndromes. In previous years, there have been reports of <200 cases in the literature; however, AF may be more common in clinical practice than reported. The most common presentation of AF is seen in adolescents starting isotretinoin therapy. Diagnosis of AF is determined based on its clinical findings. The main purpose of this article is to provide clinicians with a practical approach to treating AF. Current evidence for its treatment is limited to case reports and case series. The mainstay treatment of AF is a combination of prednisone and isotretinoin. It is important to taper or discontinue any exacerbating or precipitating medications such as isotretinoin, antibiotics, or androgens when AF is identified. Along with treatment of AF, it is important to treat associated scarring. Early identification and treatment of AF in adolescents is crucial to minimize both acute symptoms and long-term scarring, and further research is needed to determine optimal management.
