[Three cases of eosinophilichyperplastic lymphogranuloma in children's parotid area]

From March 2009 to October 2009, three pediatric patients with parotid tumor were cured. Preoperative physical examination showed regional swelling in parotid area, the surface skin was in moderate reddish purple, the border was vague, and the swelling was inactive. The patients' IgE were significantly increased. B ultrasound examination demonstrated the focus was an isoecho with ringlike dark band around, which was concluded as bull's-eye sign. Magnetic resonance imaging (MRI) examination indicated a cystic mass between the skin and parotid. Preoperative diagnosis was eosinophilichyperplastic lymphogranuloma (Kimura's disease) and the granuloma was excised by operation. Pathological examination revealed the capillary vessel hyperplasia in local tissue with a plenty of eosinophils and lymphocytes infiltrating. The disease was confirmed. Although the disease is rare, the diagnosis still could be made by preoperative physical examination, laboratory and imaging examinations.
