The cords of Billroth (also known as splenic cords or red pulp cords) are found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages.
Micrograph of the spleen showing darkly stained, spheroid Gamna-Gandy bodies (arrows) outside the vessel wall at the center. Also shown is diffusely scattered, brown, granular hemosiderin pigment (arrowheads), indicating previous hemorrhage (hematoxylin & eosin staining, 40x magnification).
Micrograph of hyaloserositis of the spleen (sugar-coated spleen). H&E stain. In pathology, hyaloserositis is the coating of an organ with a fibrous hyaline, [1] resulting from inflammation of the serous membrane covering the organ. [2] The spleen is commonly affected and often referred to as sugar-coated spleen. [3]
Spleens are also removed for therapeutic purposes in conditions like hereditary spherocytosis, trauma to the spleen, and autosplenectomy caused by sickle cell anemia. Other causes are radiation therapy involving the spleen, such as that used to treat Hodgkin lymphoma. Howell–Jolly bodies inside of two normoblasts (center) in bone marrow ...
White pulp is a histological designation for regions of the spleen (named because it appears whiter than the surrounding red pulp on cross section), that encompasses approximately 25% of splenic tissue. White pulp consists entirely of lymphoid tissue.
White pulp, splenic lymphoid nodules, or white nodules — follicles in the white pulp of the spleen, containing many lymphocytes; These structures are named after Marcello Malpighi (1628–1694), an Italian physician and biologist regarded as the father of microscopical anatomy and histology
Histology of a normal lymphoid follicle, with marginal zone annotated at bottom. It is composed of cells derived primarily from the myeloid compartment of bone marrow differentiation. More recently, a population of neutrophil-killers has been described to populate peripheral areas of the marginal zone. [ 4 ]
An image of the spleen in the human body. Also shows the red and white pulp regions. Splenocytes are spleen cells and consist of leukocytes like B and T cells, dendritic cells, and macrophages. [2] The spleen is split into red and white pulp regions with the marginal zone separating the two areas. The red pulp is involved with filtering blood ...
