Kimura's disease is a rare, idiopathic condition that usually affects young men of Asian descent. The decrease is characterized by swelling and lesions in the head and neck region, with involvement of the subcutaneous soft tissue, major salivary glands, and lymph nodes. Patients almost always have eosinophilia and elevated serum immunoglobulin E levels. The diagnosis is established by biopsy. Kimura's disease is usually self-limiting. Its etiology is unknown but is thought to be a manifestation of an aberrant allergic response. In this paper, we describe the case of a 30-year-old patient who was diagnosed with Kimura's disease at our institution.
