Eosinophilic Lung Disease Complicated by Kimura's Disease: A Case Report and Literature Review

Abstract

Kimura's disease (KD) or eosinophilic lymphogranuloma is a rare chronic inflammatory disorder of unknown etiology that occurs primarily in Asians. A 51-year-old man diagnosed three years earlier with KD of a left neck nodule was admitted to our hospital with a productive cough and pulmonary infiltration. Bronchoscopy was performed, and a diagnosis of eosinophilic lung disease (ELD) was made. The patient's condition improved after receiving corticosteroid treatment. Complications such as nephrotic syndrome have been reported in patients with KD; however, ELD has not been previously described. To the best of our knowledge, this is the first report of ELD related to KD.
