A 52-year-old man presented with general fatigue and body weight loss. Chest X-ray and computed tomography showed bilateral, mediastinal and hilar lymphadenopathy. Laboratory tests revealed that peripheral eosinophils (1,850/microL) and serum IgE levels (1,610 U/L) were markedly increased. Cervical lymph node biopsy was performed for a definitive diagnosis. Histopathological analysis, using conventional H&E staining, showed mild infiltration of eosinophils into lymphoid follicules in the cervical lymph node. Immunohistopathological analysis, using an anti-human IgE antibody, showed mesh-like IgE positive staining in lymphoid follicles. These clinical and pathological findings are compatible with a diagnosis of Kimura's disease.
