This is mainly because its principal cellular constituents, lymphocytes, are intrinsically mobile and continuously recirculate in large number between the blood and the lymph by way of the secondary lymphoid tissues… where antigens and antigen-presenting cells are selectively localized.” -Masayuki, Nat Rev Immuno.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria. -

Diffuse Large B-Cell Lymphoma with Distinctive Patterns of Splenic and Bone Marrow Involvement: Clinicopathologic Features of Two Cases
Modern Pathology (2005) 18, 495–502 & 2005 USCAP, Inc All rights reserved 0893-3952/05 $30.00 www.modernpathology.org Diffuse large B-cell lymphoma with distinctive patterns of splenic and bone marrow involvement: clinicopathologic features of two cases William G Morice, Fausto J Rodriguez, James D Hoyer and Paul J Kurtin Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA Two unusual cases of large B-cell lymphoma with predominant splenic and bone marrow (BM) involvement and similar clinical and histopathologic features are described. Both patients presented with nonspecific constitutional symptoms, unexplained cytopenias, and splenomegaly. Splenectomy revealed diffuse red pulp involvement by large B-cell lymphoma. The perisplenic lymph nodes were also involved diffusely with effacement of normal nodal architecture, excluding a diagnosis of intravascular large B-cell lymphoma. BM biopsies revealed striking erythroid hyperplasia without overt morphologic evidence of involvement by lymphoma. Immunoperoxidase staining of the marrow biopsies with antibodies to CD20 and erythroid- associated antigens revealed involvement by large B-cell lymphoma morphologically resembling the early pronormoblasts. In both cases there was prominent, but not exclusive, intravascular/intrasinusoidal lymphomatous marrow infiltration. These cases represent an unusual variant of large B-cell lymphoma with distinctive patterns of splenic and BM involvement. Furthermore, they underscore the difficulties in identifying intrasinusoidal -
The Spleen ABOLARIN A.T BUTH, OGBOMOSO Outline
The Spleen ABOLARIN A.T BUTH, OGBOMOSO Outline Structure and physiology Functions Diseases associated with the spleen The major functions of the spleen are (i) filtration and ‘quality control’ of red cells within the circulation (ii) capture and destruction of blood-borne pathogens (iii) generation of adaptive immune responses. In order to achieve these aims the Spleen has evolved a unique anatomical structure that is based on the filtering of blood through two main systems. These consist of a white pulp, which is concerned mainly with immunological function, and a red pulp, which regulates the selection of red cells for re-entry into the circulation. Structure of the spleen The normal spleen weighsabout 150–250 g, but there is considerable variation between normal individuals and at various ages in the same individual. At puberty it weighs about 200–300 g but after the age of 65 years this decreases to 100–150 g or less. In the adult its length is 8–13cm, width 4.5–7.0 cm, surface area 45– 80 cm2 and volume less than 275 cm3. A spleen greater than 14 cm long is usually palpable. Blood flow It is enclosed by a connective tissue framework that extends inwards to form a fibrous network. Blood enters at the pelvis and the majority of vessels open into these open networks(the red pulp) before re-entering the closed venous system. There is no afferent lymphatic to the spleen and the efferent lymphatic system leaves along the route of the splenic vein. The spleen contains a large amount of lymphatic tissue that is mostly concentrated in concentric rings around the arterioles (white pulp).
