An alteration in the appearance of the skin may, of course, sometimes be caused by changes under, rather than in, the skin. The case reported herein is one in which a substantial change in the appearance of the cheek was produced by the presence of a band of hyperplastic fibrous tissue inside the mouth.
Report of a Case
A 27-year-old woman sought dermatologic care because of the gradual appearance of a deep dimple in her left cheek. The dimple developed, and gradually deepened, during several months. She also became aware of a "growth" in her mouth near her upper first molar on the left side. She was in good health otherwise. She had not had any recent dental procedures, and she was not aware of any trauma to the gingiva or buccal mucosa in the affected area.On physical examination, the deep dimple in her left cheek was clearly visible.
