Periorificial facial dermatitis
Periorificial dermatitis is a term covering two erythematous
and papulopustular facial dermatoses that are strongly linked to prolonged
potent topical corticosteroid use, namely perioral dermatitis and periocular
dermatitis.
Epidemiology
It almost entirely
affects young
women of 15–25 years of age; perioral dermatitis is now recognized to occur in
children as well. The granulomatous form of perioral dermatitis has
been reported mostly in children of prepubertal age.
Pathophysiology
A relationship of perioral dermatitis to the misuse
of topical corticosteroids (fluorinated or nonfluorinated) has been well
established. Patients often reveal a history of an acute steroid-responsive
eruption around the mouth, nose, and/or eyes that worsens when the topical
corticosteroid is discontinued. Dependency on the use of the topical
corticosteroid may develop as the patient repeatedly treats the recurrent
eruption. Overuse of cosmetics and moisturizers has also been implicated in
exacerbating periorificial dermatitis, and intolerance of sunlight and hot
water are common symptoms. There
appear to be associations with atopic eczema and with the use of potentially
irritant products on the skin: impairment of the skin barrier has been
postulated as a further aetiological factor.
Clinical features
The preparation responsible may have been ‘borrowed’ for
treating trivial facial blemishes. Most medical practitioners are now fully
aware of the hazards of prolonged potent topical steroid use on the face.
The
most common presentation is clusters of monomorphous
superficial pinpoint pustules and/or pink papules, patches and thin plaques,
some of which have fine scale. The lesions are often symmetric
but may be unilateral and appear in the perioral, perinasal, and/or periocular
regions. Characteristically,
the eruption begins abruptly in the nasolabial areas spreading rapidly to the lower face and chin, usually leaving a 5-mm clear zone of unaffected skin around the mouth (mucocutaneous
junction) which then appears pale. Pustules on the cheeks adjacent to the
nostrils are highly characteristic, and sometimes the disease remains confined
to this area. There are no comedones. The
more potent the steroid, the more likely it is to result in perioral
dermatitis, although it has also been reported with hydrocortisone. Steroids
from asthma inhalers and nebulizers have also been implicated.
Periocular dermatitis is similar to perioral
dermatitis and affects the eyelids and periorbital skin. It usually results
from the use of steroid‐containing ophthalmic preparations.
In contrast to steroid-induced rosacea, periorificial dermatitis spares the
cheeks and forehead.
Granulomatous periorificial
dermatitis in children presents with monomorphous pink papules that have become
confluent around the mouth.
Disease
course and prognosis
Most patients
experience permanent remission after a fairly short course of broad-spectrum
antibiotics. Relapses occur in a small minority. However, if untreated and
especially if the provoking topical steroids are continued, perioral dermatitis
can persist for years.
Treatment
The
most important measure is to discontinue application of topical corticosteroids.
As with other corticosteroid‐induced
skin disorders, the substitution of a milder version of topical corticosteroid
will diminish the subsequent flare when the more potent preparation is stopped.
Other applications, including cosmetics, should be avoided. The patient must be
warned that an initial flare is to be expected. A 4‐8week
course of an oral doxycycline, minocycline or azithromycin
and topical
metronidazole is commonly used and is usually
effective in clearing the skin.
Unlike rosacea, clearance is
usually not followed by a subsequent relapse unless the patient is re-exposed
to the inciting trigger.
Granulomatous periorificial
dermatitis in children resolves with a 6-week course of azithromycin.
Steroid-induced
rosacea
Is a facial eruption in which
erythema, large papules and pustules, and sometimes
telangiectasias and atrophy, develop on the mid face,
including cheeks and forehead, from the repeated application of moderate to
high potent topical corticosteroid preparations to the face. Again, Demodex
mites are present in high numbers. Reducing the strength of the topical
corticosteroid application rather than its abrupt discontinuation is advisable
in order to avoid a rebound flare. Systemic antibiotics (doxycycline, minocycline
or azithromycin) are usually required for 4-8 weeks to allow the skin to
settle.
