HepatosplenomegalyOverwhelming post-splenectomy infection: An overwhelming post-splenectomy infection (OPSI) is a rare but rapidly fatal infection occurring in individuals following removal of the spleen. The infections are typically characterized by either meningitis or sepsis, and are caused by encapsulated organisms including Streptococcus pneumoniae.MyelofibrosisPeriarteriolar lymphoid sheaths: Periarteriolar lymphoid sheaths (or periarterial lymphatic sheaths, or PALS) are a portion of the white pulp of the spleen. They are populated largely by T cells and surround central arteries within the spleen; the PALS T-cells are presented with blood borne antigens via myeloid dendritic cells.Littoral cell angioma: Littoral cell angioma, abbreviated LCA, and formally known as littoral cell angioma of the spleen, is a benign tumour of the spleen that arises from the cells that line the red pulp.SplenomegalyDermatopathic lymphadenopathyHeparin-induced thrombocytopeniaMyelodysplastic–myeloproliferative diseases: Myelodysplastic–myeloproliferative diseases are a category of hematological malignancies disorders created by the World Health Organization which have characteristics of both myelodysplastic and myeloproliferative conditions.Tulane University School of Public Health and Tropical Medicine: The Tulane School of Public Health and Tropical Medicine is part of Tulane University of the U.S.Bone marrow suppression: Bone marrow suppression or myelotoxicity (adjective myelotoxic) or myelosuppression is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine.Autoimmune progesterone dermatitis: Autoimmune progesterone dermatitis may appear as urticarial papules, deep gyrate lesions, papulovesicular lesions, an eczematous eruption, or as targetoid lesions.James, William; Berger, Timothy; Elston, Dirk (2005).Lymphoid leukemiaPortal hypertensionAnemiaBlueberry muffin baby: Blueberry muffin baby is the characteristic distributed purpura occurring as a result of extramedullary hematopoiesis found in infants. The purpura are often generalized, but occur more often on the trunk, head, and neck.LeukocytosisALPSSplenic vein: The splenic vein (formerly the lienal vein) is a blood vessel that drains blood from the spleen, the stomach fundus and part of the pancreas. It is part of the hepatic portal system.Lymphoproliferative disordersDiffuse infiltrative lymphocytosis syndrome: Diffuse infiltrative lymphocytosis syndrome occurs in HIV positive patients with low CD4 counts.Hairy cell leukemiaHistiocytic sarcoma: Histiocytic sarcoma is a tumor derived from histiocytes. The tumor is often positive for CD163 and can appear in the thyroid.Louis Henri Vaquez: Louis Henri Vaquez (27 August 1860 – 1936) was a French internist born in Paris. He is known for his work in the field of hematology and his research of heart disease.Perforin: Perforin-1 is a protein that in humans is encoded by the PRF1 gene and the Prf1 gene in mice.ProguanilThrombocytosisPancytopeniaMicroangiopathic hemolytic anemiaJanus kinase 2: Janus kinase 2 (commonly called JAK2) is a non-receptor tyrosine kinase. It is a member of the Janus kinase family and has been implicated in signaling by members of the type II cytokine receptor family (e.Reticular fiber: Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue composed of type III collagen secreted by reticular cells. Reticular fibers crosslink to form a fine meshwork (reticulin).Hyper-IgM syndrome type 1United States House Committee on Mines and Mining: The United States House Committee on Mines and Mining is a defunct a committee of the U.S.Post-kala-azar dermal leishmaniasis: Post-kala-azar dermal leishmaniasis (also known as "Post-kala-azar dermatosis") is a cutaneous condition that is characterized by a macular, depigmented eruption found mainly on the face, arms, and upper part of the trunk. It occurs years(in the Indian variation)or a few months(in the African strain) after the successful treatment of visceral leishmaniasisChronic neutrophilic leukemiaOrnithinaemia: Ornithinaemia is a blood disorder characterized by high levels of ornithine. Also known as hyperornithinemia, it may be associated with psychomotor retardation or epileptic episodes.Roll Back Malaria Partnership: The Roll Back Malaria Partnership (RBM Partnership) is the global framework for coordinated action against malaria. It forges consensus among key actors in malaria control, harmonises action and mobilises resources to fight malaria in endemic countries.Polyclonal B cell response: Polyclonal B cell response is a natural mode of immune response exhibited by the adaptive immune system of mammals. It ensures that a single antigen is recognized and attacked through its overlapping parts, called epitopes, by multiple clones of B cell.Blood cell: A blood cell, also called a hemocyte, hematocyte, or hematopoietic cell, is a cell produced through hematopoiesis and is normally found in blood. In mammals, these fall into three general categories:
