Perioral dermatitis - Perioral dermatitis Treatment, picture and cause
Perioral dermatitis is seen on the lower part of the face, mainly chin and around the mouth. Perioral dermatitis is a common rash found around the mouth, especially in young females. Erythema is more evident and is accompanied by slight crusting or scaling and itching; oozing is little.
Cause of Perioral dermatitis
Presumable cause are seborrhoea, emotional stress, gastrointestinal disturbances, photosensitivity, hormonal contraceptives and use of fluorinated steroids. Course is chronic, slow and insidious with occasional exacerbations. The exact cause is unknown but it often has an iatrogenic component as topical steroids often exacerbate the condition in the long term.
Clinical features of Perioral dermatitis
It presents with erythema, scaling, papules and occasionally pustules around the mouth. It usually spares a halo of skin immediately adjacent to the lips.
Treatment of Perioral dermatitis
Treatment involves stopping topical steroids, although they may have to be withdrawn slowly to prevent too severe a rebound after withdrawal. The mainstay of treatment is with a 3- to 4-month course of low-dose oxytetracycline or erythromycin (both 500 mg twice daily).
Treatment consists of correction of the underlying causes, local use of calamine lotion and a course of tetracycline 1 gm daily till the disease is controlled and then maintained on 250 mg biweekly for 6-8 weeks or so. Andropogan muricatus infusion is very beneficial.
