CASE PRESENTATION: Patient 1 A 49-year-old man who had been admitted with intermittent cough for 16 years and recurrent enlargement of left submandibular mass for 6 years. He had undergone submandibular lymphatic nodes (SMLN) surgery for local excision in January 2008, and after short time intravenous drip of methylprednisolone the SMLN got shrinkage and eosinophil level was also dropped to normal. We re-evaluated the pathological section of excised specimens and confirm the diagnosis of Kimura's disease. To explore the reason of cough, bronchial provocation test was applied and the patient was diagnosed as airway hyper reactivity. The patient's cough symptoms and lung function is still on follow-up visit. Patient 2 An 68-year old woman complained with itchy erythematous papules for 3 years, edema of lower extremity for 2 years and pulmonary shadow for 1 year. She was diagnosed as eosinophilic dermitis and nephrotic and prescribed of oral steroid and ciclosporin for the several months. During that treatment, the patient got cough with little sputum and was found nodular shadow in the right upper lobe. Rifampicin and isoniazid could not improve the pulmonary shadow and enlarged lymph nodes. We carried out lymph node and lung biopsy and got the diagnosis of Kimura’s disease accompanied with pulmonary tuberculosis. Treatment of antituberculosis (HRSZ) and mycophenolate alleviated the patient's cough, albuminuria and yielded improved chest CT scan.
