Pyoderma faciale, also known as rosacea fulminans, is an acute, inflammatory eruption almost exclusively seen on the face of young women and characteristically sparing the trunk. This is an uncommon disorder manifested by the sudden onset of large, tender, inflammatory papules, pustules, and nodules on the face. Pyoderma faciale lacks systemic symptoms.

The etiology is unknown; however, the majority of patients report a history of rosacea or facial flushing. Triggers may include hormonal changes (ie, pregnancy, oral contraceptives, menopause) or emotional stressors. Pyoderma faciale has been noted in case reports to occur in association with inflammatory bowel disease (IBD) and small intestinal bacterial overgrowth (SIBO).
