Extranodal NK/T-cell lymphoma nasal type is a rare disease that mainly affects the nasal cavity and paranasal sinuses of males in the fifth decade of life. It has aggressive and locally destructive behaviour, and can be complicated by the hemophagocytic syndrome, conferring high lethality to the disease. This article describes a case of NK/T-cell lymphoma nasal type in a previously healthy patient, exemplifying its rapid and fulminant course.

Hemophagocytic lymphohistiocytosis (HLH) is a rare syndrome of widespread inflammation due to massive amounts of cytokines released from activated macrophages. The most common trigger for HLH is infection from a virus, most commonly Epstein-Barr virus. Here we report an adult case of this rare and life-threatening syndrome.

BACKGROUND: Hemophagocytic Lymphohistiocytosis (HLH), a rare but potentially fatal syndrome of immune hyperactivation, may be an under-recognized immune-related adverse event (irAE). Unlike other irAEs, HLH triggered by immune checkpoint blockade is not well described; no particular diagnostic guidelines and treatment regimens exist. The HLH-2004 criteria remain as the common diagnostic guide. For the treatment of HLH, various combinations of chemotherapeutic, immunosuppressive and glucocorticoid agents are used...

Autoimmune lymphoproliferative syndrome (ALPS) usually presents in childhood with fever, nonmalignant splenomegaly and lymphadenopathy along with hemocytopenia. This case report describes a 10-year-old boy presenting with signs of autoimmune disease, splenomegaly, hepatomegaly and resistant hemocytopenia. Sirolimus controlled the relapsed thrombocytopenia after splenectomy. Sequencing of the FAS gene identified two spontaneous heterozygous mutations (c.234 T > G, p.D78E) (c.236dupA, p.P80Tfs*26). The boy's homozygous missense variation (c...

Background . Brucellosis has a wide spectrum of clinical manifestations and it may last several days or even several years; however, it is often misdiagnosed and therefore may cause inadequate therapy and prolonged illness. Previous studies about meta-analysis of manifestations of brucellosis reported in English lacked the data published in Chinese, which did not provide details about the contact history, laboratory tests, and misdiagnosis. We undertake a meta-analysis of clinical manifestations of human brucellosis in China to identify those gaps in the literature...

This study aims to investigate the clinical significance of serum soluble CD163 (sCD163) levels as a predictor of the disease activity of systemic juvenile idiopathic arthritis (s-JIA). In this study, we examined 63 patients with s-JIA, four with Epstein-Barr virus-induced hemophagocytic lymphohistiocytosis (EBV-HLH), and seven with Kawasaki disease (KD), along with 14 healthy controls. We quantified serum cytokine levels (sCD163, neopterin, IL-18, IL-6) by enzyme-linked immunosorbent assay and compared the results with the clinical features of s-JIA...

Hemophagocytic lymphohistiocytosis (HLH) is a severe inflammatory disorder characterized by the uncontrolled proliferation of lymphocytes and histiocytes with hemophagocytic activity in the bone marrow. To our knowledge, there have been a few reported cases of pregnancy-related HLH. This case highlights the importance of considering HLH in a pregnant woman along with other diagnoses, such as HELLP (which stands for hemolysis, elevated liver enzyme levels, and low platelet levels) syndrome and hemolytic anemias...

Intravascular large B cell lymphoma (IVLBCL) is a rare and aggressive subtype of diffuse large B cell lymphoma, of which clinical presentations are highly variable among geographical areas. A case series of IVLBCL patients from Asian countries reported the disease to be more aggressive and associated with hemophagocytic syndrome than in cases from Western countries. Although published articles recently revealed hypoxemia as a presentation in IVLBCL patients, orthodeoxia has never been documented. A 71-year-old man presented with prolonged fever, cough, exertional dyspnoea, and orthodeoxia, later developing hypoxemic respiratory failure and refractory septic shock...

Familial hemophagocytic lymphohistiocytosis 2 (FHL2) is a cytokine storm syndrome characterized by immune hyperactivation with viral infection due to a CD8 T cell cytotoxic killing defect secondary to a perforin deficiency. As most studies of FHL2 mice have used pathogen naïve animals, the effects of immune memory on FHL2 are understudied. We utilized an immunization model of the perforin-deficient mouse to study the effects of immune memory on FHL2. Prior CD8 T cell specific antigen exposure leads to enhanced HLH disease with increased morbidity and decreased time to mortality...

Hemophagocytic syndrome (HPS) associated with systemic lupus erythematosus (SLE), dubbed acute lupus hemophagocytic syndrome (ALHS), is an intractable complication of SLE. A 24-year-old man who had been diagnosed with SLE three months previously, presented with fever, rash, hallucination, and pancytopenia accompanied with hyperferritinemia and bone marrow hemophagocytosis. He was diagnosed with ALHS and neuropsychiatric (NP)-SLE. Although 4 courses of methylprednisolone pulse therapy and 1 course of intravenous cyclophosphamide (IVCY) improved his NP-SLE, his ALHS did not respond...

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome that occurs as a complication in many clinical settings. Malignancy-associated HLH develops in patients with hematopoietic neoplasms, particularly in those with lymphoma, and its development in those with myelodysplastic syndrome (MDS) is uncommon. We herein report a case of HLH in a patient with low-risk MDS that was successfully treated with azacitidine. The prevalence of immune abnormalities among MDS patients and the immune effects of azacitidine have recently been elucidated, suggesting that MDS-associated HLH occurs as a result of immune impairment, and azacitidine improves this condition by restoring the immune system...

Hemophagocytic lymfohistiocytosis (HLH) is rare, life-threatening condition, characterized by excessive activation of immune system with subsequent proinflammatory state resulting in multiorgan failure. Most frequently, it appears in infancy as a primary disorder caused by mutation of immune-regulatory genes. Increasingly, HLH is being diagnosed as a secondary - adult - form, which occurs as a result of aberrant immune response. Viral or bacterial systemic infections, malignancy with a predominance of lymphoproliferative disorders and autoimmune diseases are the most common triggers...
