Abstract
Periorificial dermatitis is a common eczematous eruption on the face. Clusters of follicular papules, vesicles, and pustules on an erythematous base are usually found in a perioral distribution. Other common locations include the nasolabial folds and periocular area. An underlying cause may not be found in all cases, but the use of topical corticosteroids on the face may precede onset of symptoms. Periorificial dermatitis is diagnosed clinically and no specific investigation is required. Topical anti-inflammatory therapies (such as metronidazole and erythromycin) are appropriate in mild cases. In severe cases, systemic treatments such as tetracycline or one of its derivatives are beneficial. Patients should be warned that symptoms might worsen before improvement is apparent. This complication is more commonly seen when topical corticosteroids are withdrawn.
