Prolonged friction and pressure on limited areas of the skin with other naked skin parts of the patient, occurring mostly from positional attitudes, as, for instance, resting the chin on the hands or knees while watching television, may cause peculiar cutaneous lesions. The occurrence of some cases of this dermatologic picture has led to the description of a dermatosis heretofore not reported that has been denominated traumatic anserine folliculosis (folliculosis anserina traumatica) — stressing the traumatic etiology, the goose skin (anserine) appearance and the follicular clinical aspect that may resemble keratosis follicularis. Up to now, 11 cases have been observed, occurring on the chin of 9 patients (also in both jaws of 1), on the right jaw of 1 and the neck of 1. The problem occurs mostly in children or young people; apparently delicate skin is an important factor. About 63.6% of the patients have an atopic background: On the points of friction and pressure ill limited patches of grouped, very small conical elevations are seen, either the same color as the patient's skin, or slightly hyperpigmented, with or without erythema and showing a goose skin (anserine) appearance. Tactilely, it resembles sand paper. The histopathology is characterized by varied but not intensive changes. In tissue sections may be seen: rudimentary follicles, follicular hyperkeratosis, focal increase of stratum lucidum, slight hypergranulosis, vasodilatation especially nearby the follicles, and small perivascular infiltration, predominantly lymphocytic.
