Kimura disease: An unusual cause of head and neck masses. Report of 2 cases.

Kimura disease is an uncommon chronic, benign, inflammatory condition of unknown etiology. It occurs endemically in Asia and sporadically in the West. Because it often imitates neoplastic or inflammatory processes of the head and neck, otolaryngologists and head and neck surgeons should be aware of its clinical presentations. In this article, the author reports 2 cases of Kimura disease-1 that was characterized by an unusual bilateral presentation and 1 that was managed conservatively-and he briefly reviews the literature on this entity.
