Kimura's disease--report of four cases.

Kimura's disease is a rare benign condition that occurs predominantly in Oriental young people. The patients displayed a variety of manifestations such as painless, tumor-like masses in the head and neck regions, or in the salivary glands with associated lymphadenopathy. They are sometimes initially mistaken for malignant tumors, resulting in improper management. We present four cases of Kimura's disease and a comprehensive review of the literature to increase awareness and alert surgeons and pathologists to consider the possibilities of this disease, especially in Oriental patients having peripheral blood eosinophilia and/or elevated serum IgE.
