Kimura disease

Kimura disease is a benign rare chronic inflammatory disorder of unknown etiology that involves the lymph nodes and subcutaneous tissue of the head and neck regions. Elevated serum immunoglobulin E levels and peripheral blood eosinophilia are also common. This disease is most common in middle-aged Asian men. Although the etiology is unknown, it most probably represents an aberrant chronic immune response. Treatment for Kimura disease includes surgical resection and regional or systemic steroid therapy. Cytotoxic therapy and radiation have also been utilized. The disease has an excellent prognosis, although it may recur locally.
