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.

A 53-year-old Japanese male noticed pigmented lesions on his right upper gingiva and hard palate in February of 1986. Histological examination revealed in situ malignant melanoma. Chemotherapy, beta-interferon, and oral BCG were given. However, tumors subsequently developed in the nasal cavity in March of 1989. The patient died in April of 1990 after developing Garcin's syndrome and the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Autopsy revealed aggressively infiltrating, whitish tumor masses invading the hard palate, the nasal cavity, the paranasal sinuses, the base of the skull, cranial nerves I-X, and the pituitary body, as well as severe necrosis of the soft palate. However, there was no evidence of malignant melanoma. Instead, these oval tumor cells had atypical nuclei and scanty cytoplasm. They contained no melanin granules, were negative for S-100 protein, and were also negative for various melanoma-associated antigens. They were positive for CD2, CD3, and CD8 by avidin-biotin-peroxidase complex immunohistochemistry. It was concluded that the patient had CD8+ non-Hodgkin's malignant lymphoma (diffuse, large cell type) of the nasopharyngeal region, which was preceded by in situ malignant melanoma of the palate.

Polyuria is usually the result of a water diuresis or an osmotic diuresis. Traditionally, the assessment of the extracellular fluid (ECF) volume and the concentration of Na+ in plasma is sufficient to differentiate between the two. We present a case and our approach, which is based on calculations and quantitation of osmoles, to demonstrate the utility of this approach. A patient with diabetes mellitus, human T-cell lymphocyte virus, type 1 (HTLV-1) associated lymphoma, and hypercalcemia presented with marked ECF volume contraction and polyuria. A spot urine osmolality was 567 mOsm/kg H2O in the face of urine output of approximately 6 L/d. The initial diagnosis was an osmotic diuresis. However, a quantitative analysis revealed the enormous number of osmoles could not be accounted for physiologically. Hence, we postulated a water diuresis to be the cause of the polyuria. To confirm this hypothesis, we found that at different times during his hospitalization, the urine specific gravity ranged from 1.005 to 1.022, and urine output varied markedly over 8-h periods. Despite a plasma sodium of 147 mmol/L, the patient did not complain of thirst. Taken together, this suggested the presence of a hypothalamic lesion which caused central diabetes insipidus with variable output of antidiuretic hormone together with a blunted thirst response. Illustration of the utility of a quantitative approach to polyuria is the focus of the discussion.

A patient with high fever, loss of weight and profound pancytopenia is reported. Peripheral T-cell lymphoma with hemophagocytosis was diagnosed. Bone marrow was the only localisation of the lymphoma. At presentation there were (i) a coagulopathy consistent with hemophagocytic histiocytosis (ii) the features of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). These different abnormalities disappeared after chemotherapy and reappeared during each of the 2 periods of disease progression. The patient died 6 months after diagnosis without ever achieving complete remission. As far as we are aware this is the first case report of T-cell lymphoma with hemophagocytic syndrome localised to the bone marrow and associated with SIADH.

We report a syndrome of inappropriate secretion of antidiuretic hormone (SIADH), neurotoxicity and facial erythema induced by several anti-cancer drugs in a case of malignant lymphoma of thyroid gland. A 68-year-old male was admitted, complaining of neck tumor and dyspnea. On admission, he was treated with vincristine (VCR) for bronchostenosis due to malignant lymphoma. Neck tumor and mediastinal lymph node swelling reduced. On the ninth day after chemotherapy of VCR, a consciousness disturbance was found and he was diagnosed as having SIADH. Following chemotherapy of cyclophosphamide, SIADH was also induced so he was treated with irradiation for neck and mediastinal field, instead of chemotherapy. During irradiation, however, enlargement of systemic lymph nodes appeared, and the chemotherapy was resumed. He achieved partial remission, but somnolence after ifosfamide and facial erythema after ranimustine were observed. In spite of the difference in the chemical structure of these anti-cancer drugs, several side effects occurred. It is suggested that the direct effects of drugs on the nervous system were SIADH and neurotoxicity.

The syndrome of inappropriate antidiuretic hormone (SIADH) has been described in patients suffering from leukemia or lymphoma involving the central nervous system. Several alkylating agents have also been associated with this syndrome. We describe a patient with chronic lymphocytic leukemia, without evidence of central nervous system involvement, who suffered from SIADH presumably caused by small doses of chlorambucil.

A 37-year-old male patient with a diffuse pleomorphic B-cell-lymphoma, which has been diagnosed two month earlier with the primary site at the pterygopalatine fossa on both sides with infiltration of the clivus and cavernous sinus was referred to our hospital for continuation of the third course of CHOP chemotherapy. At admission he reported about a recent history of painful swallowing and intermittent substernal chest pain. Alleviation of the pain on swallowing and the chest pain was apparently only possible by drinking 10 to 15 l of cold coca cola throughout the day and night, a regimen that resulted in polyuria. Physical examination revealed extensive thrush stomatitis and soor esophagitis. Despite successful treatment with fluconazole, polydipsia continued unabated. The classic osmotic test of dehydration and exogenous vasopressin revealed hypothalamic diabetes insipidus (DI). Basal hormones and stimulated endocrine function tests of the adenohypophysis were found to be normal. MRI-scan revealed lymphoma infiltration of the neurohypophysis. After the third course of CHOP chemotherapy the patient surprisingly recovered completely from his excessive thirst. The present report shows that clinical disorders such as thrush stomatitis can mask diabetes insipidus caused by an early relapsing lymphoma.

A case of angiotropic B-cell lymphoma associated with hemophagocytic syndrome (HPS) has been reported. In addition to fever, pancytopenia, hepatosplenomegaly, and lack of lymphadenopathy, unique clinical features, such as syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and pulmonary infarction, were manifested. Both soluble interleukin-2 receptor (sIL-2R) and IL-6 were elevated in the patient's sera in addition to an increase of serum lactate dehydrogenase and ferritin. In contrast, tumor necrosis factor-alpha and interferon-gamma were within normal ranges. Serum antibodies against Epstein-Barr virus and cytomegalovirus showed a past infection pattern. An autopsy examination revealed systemic intravascular proliferation of lymphoma cells with a B-cell phenotype, confirming the diagnosis of angiotropic B-cell lymphoma. Moreover, SIADH was suggested to result from the infiltration of tumor cells into the pituitary gland. Triple association of angiotropic B-cell lymphoma, HPS and SIADH is quite rare. Therefore, the present case seems to be helpful for clarifying the mechanism for HPS of non-Hodgkin's lymphoma with B-cell origin.

Tumor types expressing a neuroendocrine phenotype secrete neuropeptides with paracrine or autocrine growth factor activity. The efficacy of these paracrine or autocrine loops depends on the expression of specific receptors on tumor cells. Once specific receptors are identified, specific neuropeptide antagonists disrupting paracrine and autocrine loops could be potential treatments in neuropeptide-secreting tumors. In the present study, 11 human tumor cell lines representing astrocytoma, lymphoma, and pancreatic, prostate, lung and colon carcinomas were examined for expression of five different neuropeptide receptors (cholecystokinin, neurotensin, vasopressin, tachykinine substance P and cannabinoid) using RT-PCR and radioligand binding. The presence of various neuropeptide receptors in different human cancer cell lines supports development of new antitumor treatments based on disruption of neuropeptide autocrine growth pathways.

Central diabetes insipidus (DI) can be the outcome of a number of diseases that affect the hypothalamic-neurohypophyseal axis. The causes of the condition can be classified as traumatic, inflammatory, or neoplastic. Traumatic causes include postoperative sella or transection of the pituitary stalk, while infectious or inflammatory causes include meningitis, lymphocytic hypophysitis, and granulomatous inflammations such as sarcoidosis and Wegener's granulomatosis. Various neoplastic conditions such as germinoma, Langerhans cell histiocytosis, metastasis, leukemic infiltration, lymphoma, teratoma, pituitary adenoma, craniopharyngioma, Rathke cleft cyst, hypothalamic glioma, and meningioma are also causes of central DI. In affected patients, careful analysis of these MR imaging features and correlation with the clinical manifestations can allow a more specific diagnosis, which is essential for treatment.
