title: [Lennert's lymphoma associated with the syndrome of inappropriate secretion of antidiuretic hormone and autoimmune hemolytic anemia].
abstract: We report a case of Lennert's lymphoma complicated by the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and autoimmune hemolytic anemia (AIHA). A 76-year-old female patient was admitted to our hospital because of cervical lymph node swelling. A diagnosis of Lennert's lymphoma was made by histological examination of the biopsied lymph node. She was also diagnosed as SIADH and AIHA. After the patient was treated with COP-BLAM therapy, lymph-adenopathy, SIADH and AIHA improved. However, lymph node swelling and hyponatremia became exacerbated again after the third course of COP-BLAM therapy. Then she was treated with IMV-triple P therapy. Eventually, she died of aspergillus pneumonia. The etiology of her SIADH was suggested to be an abnormal feedback mechanism of ADH secretion due to the infiltration of lymphoma cells into the diencephalic-hypophysial system.
