[A case of eosinophilic granuloma of the cervical lymph nodes associated with pulmonary cystic lesions].

A 33-year-old man was referred to our department because of left cervical lymphadenopathy for one month which did not respond to antibiotics. Histological examination of the lymph node biopsy revealed eosinophilic granuloma. However, repeated bronchoscopic examinations performed to evaluate the pulmonary lesions appearing on chest roentgenograms and chest CT scans revealed no evidence of eosinophilic granuloma. Steroid therapy resulted in resolution of the cervical lymphadenopathy, but the pulmonary lesions showed no response. The possible relationship between eosinophilic granuloma and pulmonary cystic lesions in our patient is discussed.
