Acne fulminans is a rare severest acne mainly affected with teenage boys with sudden onset of fulminant necrotizing acne presenting simultaneously with synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome-like bone lesions and systemic symptoms. Histopathologically, massive inflammatory process around the sebaceous glands is observed. We present a case of face predominant acne fulminans without back and chest lesion.
