A 66-year-old female with follicular lymphoma developed severe liver dysfunction and nonallergic bronchitis after 1 cycle of treatment with bendamustine and rituximab (BR) therapy. Simultaneously, eosinophilia was observed. Further examination revealed negative results for both hepatitis virus-induced liver damage and lymphoma cell invasion into the liver. No bacterial, fungal, or cytomegaloviral infections of the respiratory tract were observed. The patient was treated with steroid pulse therapy followed by prednisolone with complete resolution of her symptoms. This suggests that eosinophilia induced by the treatment with BR may result in liver dysfunction and nonallergic bronchitis.
