Kimura's disease: clinical, histological and immunohistochemical studies

Kimura's disease--an unusual cause of lymphadenopathy in children

Kimura's disease is a rare inflammatory disorder of unknown cause primarily seen in young Asian males. The disease is characterized by a triad of painless subcutaneous masses in the head or neck region, blood and tissue eosinophilia, and markedly elevated serum immunoglobulin E levels. We describe a 3-year-old Indian boy with Kimura's disease who presented with generalized lymphadenopathy. The diagnosis was based on the characteristic histopathologic findings after surgical excision in conjunction with peripheral eosinophilia and elevated serum immunoglobulin E levels.

Kimura's disease: an unusual cause of cervical tumour

An 11 year old Chinese boy developed a unilateral cervical mass associated with pronounced eosinophilia and a marked increase in IgE concentrations. A biopsy sample showed massive eosinophilic tissue infiltration consistent with Kimura's disease. This disorder should be suspected when the clinical triad of painless unilateral cervical adenopathy, hypereosinophilia, and hyper-IgE is present, particularly in male Asian patients.
