Acne fulminans

Overview
Course & target group: Acne fulminans is the most severe variant of acne conglobata with an acute systemic inflammatory course and predominantly affects male adolescents.
Clinical features: ulcerating, necrotizing lesions are present, accompanied by fever + polyarthralgia and hepatosplenomegaly.
Associations: Particularly with SAPHO syndrome as well as chronic inflammatory bowel diseases.
Therapy: Initial systemic glucocorticoid therapy, followed by cautious introduction of isotretinoin over several months, with a low starting dose.
- Bodybuilder acne fulminans / Doping-associated form: Anabolic steroids (testosterone derivatives, high protein supplement doses) are classic triggers of acne fulminans in muscular young men. What to look out for? CK levels + only moderate physical activity — under isotretinoin + intensive strength training, there is a risk of rhabdomyolysis. Discontinue anabolic steroids immediately.
