What is Perioral dermatitis?

Perioral dermatitis is a type of dermatitis that occurs only around the mouth, nose and eyes. It does not have to be present in all of the areas at the same time.

Some dermatologists believe that Perioral dermatitis does really exist and that patients that fit the clinical picture of Perioral dermatitis has Rosacea. Rosacea and Perioral dermatitis can sometimes be present in the same patient. Because it is always more likely that a patient has 1 condition rather than two, the finding of both Rosacea and Perioral dermatitis in the same patient support to the thesis that the 2 conditions are in fact the same. Furthermore, when looking at a sample of skin under the microscope, both Rosacea and Perioral dermatitis displays the same type of inflammation, knows as a granulomatous peri-folliculitis. The word granulomatous refers to a collection of macrophages (a type of white blood cell). Peri-folliculitis means that the “collection of macrophages” is lying in close proximity to a hair follicle.

Whether or not Rosacea and Perioral dermatitis are the same disease or two separate diseases is an academic question and not very important from a treatment perspective. The fact is that the clinical picture known as Perioral dermatitis is quite classic and most often easily recognizable and treatable.

Classically young female patients are affected. The rash consists of small red bumps (knows as papules) and occasionally small pimples (knows a pustules) occurring around the mouth, nose and eyes. Interestingly, a small margin of skin around the edge of the lips are always unaffected. As mentioned before not all 3 of these areas has to be affected at the same time.

More than 80% of patients with Perioral dermatitis have been applying corticosteroid-containing creams to the face, before the rash started to appear. In the remaining cases the cause is unclear, but the excessive use of facial products seem to be another common factor.

The treatment of this condition involves the elimination of all (if possible) facial products. If topical corticosteroid-containing creams have been used they should be tapered off slowly and not stopped suddenly, because this will lead to a flare-up of the condition.

The treatment of Perioral dermatitis involves the use of oral tetracycline antibiotics for a few months. Sometimes this is combined with antibiotic creams, but in general it is better to avoid as many creams as possible. Most often this approach results in complete clearance of the skin condition in a few weeks.

    1. Dear Nubian. One possible diagnosis is Pruritic Papular Eruption of HIV. The primary treatment of this condition is ARV’s. Once the PPE is controlled the pigmentation should fade over months…. Come and show me, if you can, so that I can make a definite diagnosis.
