Abstract
Pyoderma faciale was originally described by O'Leary and Kierland in 1940. It is characterized by the sudden onset of monstrous coalescent nodules and confluent draining sinuses confined to the face of young women in their early 20s. This report summarizes our results in 20 cases. The women were 15 to 46 years old (mean, 25 years). All women were flushers and blushers. Histopathologic examination revealed a dense perivascular and periadnexial infiltrate, including granulocytes, eosinophils with epithelioid granulomas, and septal and lobular panniculitis. No consistent laboratory abnormalities were found. After much therapeutic experimentation, we developed an effective treatment plan, based on a combination of oral isotretinoin and corticosteroids. We regard it as an extreme form of rosacea and suggest it be renamed rosacea fulminans in analogy with its counterpart, acne fulminans.
