Micropapular sarcoidal facial eruption in a child: Gianotti-type perioral dermatitis.

The case is described of a boy aged 13 years reported with a diffuse facial micropapular eruption which had a granulomatous histology. The diagnosis is consistent with perioral dermatitis of the Gianotti type (4, 5). It is postulated that bubble gum was the cause of the condition, the most likely ingredient being the essential oils in the gum, which may actually be selectively absorbed by the follicle to produce a perifollicular granulomatous reaction. In this article we have added yet another possible cause for perioral dermatitis.
