This variant was first described by O’Leary and Kierland under the designation pyoderma faciale. It has been a matter of controversy ever since. One can say with certainty that it is neither a variant of acne nor a pyoderma. We interpret it to be an extreme form of rosacea conglobata. In analogy to its acne counterpart, acne fulminans, we opt to call it rosacea fulminans.
