Death from Hemophagocytic Lymphohistiocytosis Syndrome Due to Generalized Hemorrhage

Hemophagocytic lymphohistiocytosis (HLH) is the result of excessive cytokine release, leading to over-response by immune cells, such as macrophages and T lymphocytes. Here, we report a lethal case of HLH with a complete clinical course. The patient was a 45-year-old man with fever and chills since two months ago plus splenomegaly, hepatomegaly, and pancytopenia. The Anti-HBc IgM was positive, b...

Autoimmune Lymphoproliferative Syndrome Misdiagnosed as Hemophagocytic Lymphohistiocytosis A Case Report

Autoimmune lymphoproliferative Syndrome (ALPS) is a rare inherited disorder of apoptosis. It usually presents with chronic lymphadenopathy, splenomegaly, and symptomatic cytopenia in a child. Herein, we report a 14-year-old boy with symptoms misdiagnosed as hemophagocytic lymphohistiocytosis who was treated before ALPS was diagnosed for the patient. This case should alert pediatricians to consi...

Hemophagocytic lymphohistiocytosis secondary to T-cell Acute Lymphoblastic Leukemia with membranous tonsillitis

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome of excessive immune activation, which is characterized by fever, hepatosplenomegaly, cytopenias, hyperferritinemia, hypertriglyceridemia, and/or hypofibrinogenemia, and evidence of hemophagocytosis. Secondary HLH is often seen in adults and categorized based on autoimmune, infections-related, and malignancy-associated etiol...
