Steroid-sensitive anemia in a boy on dialysis - An association with Kimura disease

The cause of hypereosinophilia (EO) in hemodialysis (HD) patients is multifactorial and is felt to be a benign laboratory abnormality related to dialysis or uremia. Kimura disease (KD) is an angiolymphoid proliferative disorder of unknown etiology. Many cases are associated with nephrotic syndrome in children; however, it has seldom been reported in children on dialysis. We report here a 13-year-old boy who developed persistent EO and subsequent anemia after maintenance HD; he later developed KD. The atypical clinical manifestation of KD and its relationship to HD and erythropoietin hyposensitive anemia in this patient are discussed.
