Perioral Dermatitis
Essentials
- A disease of unknown aetiology mostly affecting women
- Cosmetics and local glucocorticoids on the face have been suspected as causative agents.
- Mild symptoms may be treated with topical treatments. Antimicrobials of the tetracyclines group are used as systemic medication.
Clinical features
- Small erythematous papules and single small pustules, but no comedones or scars (pictures 1 2 34).
- Occurs in young or middle-aged women in the surroundings of the nose (picture 5) or mouth; sometimes also around the eyes (periocular dermatitis; (pictures 6 7 8)), which can become worse especially with glucocorticoid creams (picture 9).
Investigations
- No diagnostic tests are available.
Treatment
- If the patient is using topical glucocorticoids on the face, the drug is discontinued, gradually if possible. Too rapid discontinuation may cause exacerbation of symptoms.
- In mild cases, topical treatment may suffice.
- A metronidazole cream or gel 1-2 times daily for 3-4 months
- Pimecrolimus cream 1-2 times daily for 1-2 months (not an official indication)
- Azelaic acid twice daily for at least 4 weeks, and longer if required
- Ivermectin once daily for no longer than 4 months.
- Primarily drugs in the tetracyclines group are used as systemic medication. Treatment duration varies between 4 and 16 weeks.
- If tetracyclines cannot be used, erythromycin can be used as an alternative, 250 mg twice daily or 500 mg once daily, treatment duration as above.
