A 15 year old girl presented with excessive thirst and hypertension (170/110 mm Hg). Biochemical investigations revealed serum sodium 118 meq/liter, serum osmolality 238 mosmol/liter, urine sodium 90 meq/liter, urine osmolality 700 mosmol/liter, persistenly elevated serum antidiuretic hormone (ADH) levels (5.8 to 11.9 pg/ml) and no obvious cause for the hypertension. The hypertension is, at least in part, volume-related, diminishing with fluid restriction. Features of gross water intoxication (e.g., confusion, coma) have not occurred. The etiology of the inappropriate secretion of ADH is not obvious but is not thought to be due to "resetting of osmoreceptors" as evidenced by failure to maximally dilute urine following a water load test and persistently elevated serum ADH levels. A similar patient described by Epstein and associates in 1962 is presently well with persistent features of inappropriate secretion of ADH.

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.

Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe drug hypersensitivity reaction characterized by rash, fever and multi-organ failure. Limbic encephalitis (LE) is a rare disorder characterized by cognitive dysfunction with memory disturbance, seizures and psychiatric symptoms. We herein present an unusual case of DRESS syndrome due to lamotrigine with reactivation of Epstein-Barr virus, which developed autoimmune LE and syndrome of inappropriate antidiuretic hormone secretion. Discontinuation of lamotrigine, administration of methylprednisolone and intravenous immunoglobulin led to improvement. The LE in this case might have been caused by an autoimmune inflammatory mechanism associated with DRESS syndrome.

We report a case of natural killer (NK)/T-cell lymphoma with concomitant syndrome of inappropriate antidiuretic hormone secretion (SIADH). The patient was a 64-year-old woman with a history of nasopharyngeal carcinoma of over 30 years. She was admitted with a chief complaint of intermittent fever for 2 mo. Palpation after admission indicated a swollen lymph node below the left jaw. Multiple imaging examinations on admission indicated multiple enlarged lymph nodes throughout the body. We performed a left submandibular lymph node biopsy, and the results revealed NK/T-cell lymphoma. A biochemical examination indicated Epstein-Barr virus positivity. At the same time, the patient developed hyponatremia. Based on her laboratory examination and clinical manifestation, decreased plasma osmolality, urine osmolality greater than plasma osmolality, lack of skin swelling, normal blood pressure, normal renal function, no adrenal function detected on serology, and no abnormalities in imaging examination of the adrenal glands, the likelihood of SIADH in the patient was high. After fluid restriction and administration of sodium chloride, the patient's blood sodium level gradually increased. Subsequently, the immune function of the patient declined, there were severe symptoms of infection, and she died of respiratory failure. NK/T-cell lymphoma associated with SIADH has not, to our knowledge, been previously reported in PubMed. This case emphasizes the importance of monitoring serum ion levels, especially serum sodium, in patients with NK/T-cell lymphoma.

Intravascular lymphomatosis (IVL) is a rare type of B-cell non-Hodgkin lymphoma (BCNHL), which can mimic many other diseases. Fever, neurological symptoms, and skin findings are the most frequent clinical findings. Intravascular lymphomatosis may be associated with genetic factors and infection with human immunodeficiency virus (HIV), human herpesvirus 8 (HHV-8), human T-lymphotropic virus 1 (HTLV1), Epstein-Barr virus (EBV), and hepatitis B virus (HBV). A 50-year-old man was hospitalized with recalcitrant hyponatremia of unknown cause. He had also telangiectatic, indurated, slightly erythematous plaques on his trunk for the last 10 days. His past medical history was unremarkable, although he was a carrier of hepatitis B. Multiple skin biopsies were performed and were considered to be diagnostic of IVL. The hyponatremia was unresponsive to water restriction and hypertonic solution support but it resolved with B cell directed chemotherapy. A final diagnosis was made as syndrome of inappropriate antidiuretic hormone (SIADH) in the setting of IVL. This case had a relatively early diagnosis with just 10-days of skin lesions. Intravascular lymphomatosis is a very rare disease and is usually difficult to diagnose. An even more uncommon presentation is IVL complicated by a paraneoplastic syndrome. There are prior reported cases of SIADH in the setting of IVL. However, this case underscores the importance of evaluating patients with SIADH for potential IVL.

Hemophagocytic lymphohistiocytosis (HLH) is also known as hemophagocytic syndrome. It is a lethal hematologic condition due to a dysregulated immune response which results in inappropriately activated macrophages damaging host tissues. Based on the etiology, HLH can be primary (genetic) or secondary (acquired). The most common cause of a secondary HLH is an infection. Viral infections are the most common cause of secondary HLH. Among the viral causes of secondary HLH, Epstein-Barr virus is the most common etiologic agent. Cytomegalovirus (CMV) is a common causative pathogen in the immunocompromised host but is rare in an immunocompetent adult. In infection- associated secondary HLH, treatment includes antimicrobial therapy. HLH carries a high mortality and morbidity rate as it is an underdiagnosed clinical condition. Successful early diagnosis allows for adequate time for curative therapy. Treatment for HLH includes chemotherapy, immunomodulators, and a hematopoietic stem-cell transplant. The 2004 diagnostic criteria set by the Histiocyte Society serves as a guide to make an earlier clinical diagnosis. A review of PubMed literature revealed only five reported cases of CMV-induced HLH. We describe the sixth case of CMV pneumonitis-induced HLH and syndrome of inappropriate antidiuretic hormone secretion in a 72-year-old White male. He was treated successfully with oral valganciclovir and corticosteroids.
