Background: Also known as papulopustular dermatitis (chronic form), rosacea-like dermatitis, periorificial dermatitis, or airhostess’ dermatitis, perioral dermatitis is a commonly encountered dermatological disease, especially in adult women and less frequently in children. Its diagnosis and treatment are a challenge especially in small children.
Case report: We present the case of a 2-year-old girl referred to the dermatologist for widespread erythematous papules, vesicles, and pustules on the perioral area, nasolabial folds, and on the outer region of the lower eyelids. Several diagnoses had been established during the previous months: impetigo, atopic dermatitis, seborrheic dermatitis, allergic contact dermatitis, childhood rosacea, demodecidosis, infantile acne, and variable therapeutic approaches had been tried, with no clinical improvement. Clarithromycin 250 mg/day orally associated with the application of 2% erythromycin solution were successfully used.
Conclusion: This case highlights the importance of the clinical diagnosis of perioral dermatitis in young children, of excluding other diagnoses and worthless treatments, and also the chronic evolution of the disease and its individualized treatment.
