Splenic marginal zone lymphoma (SMZL) is a type of marginal zone lymphoma, a cancer made up of B-cells that replace the normal architecture of the white pulp of the spleen. The neoplastic cells are both small lymphocytes and larger, transformed lymphoblasts , and they invade the mantle zone of splenic follicles and erode the marginal zone ...
Extranodal marginal zone lymphomas (EMZLs) are a form of MZL [9] in which malignant marginal zone B-cells initially infiltrate MALT tissues of the stomach (50-70% of all EMZL) or, less frequently, the esophagus, small intestine, large intestine, rectum, conjunctiva of the eye, nasal passages, pharynx, lung bronchi, vulva, vagina, skin, breast, thymus gland, meninges (i.e. membranes) that ...
The spleen's marginal zone contains multiple subtypes of macrophages and dendritic cells interlaced with the MZ B cells; it is not fully formed until 2 to 3 weeks after birth in rodents and 1 to 2 years in humans. [6]
The marginal zone is the region at the interface between the non-lymphoid red pulp and the lymphoid white-pulp of the spleen. (Some sources consider it to be the part of red pulp which borders on the white pulp, while other sources consider it to be neither red pulp nor white pulp.)
Lymphoma is a group of blood and lymph tumors that develop from lymphocytes (a type of white blood cell). [7] The name typically refers to just the cancerous versions rather than all such tumours. [7]
DLBCL is an aggressive type of B-cell NHL that grows rapidly in the lymph nodes and frequently involves the spleen, ... Barta SK. 2021 update on diffuse large B cell lymphoma: a review of current ...
Marginal zone lymphoma (MZL) is a heterogeneous group of indolent B cell lymphomas that arise from the marginal zone of lymphoid tissues. [17] It accounts for 5–10% of all NHL cases, with an annual incidence of 0.4 to 1.0 per 100,000 in Western countries. [18]
Splenic marginal zone lymphoma (SMZL) (also known as well-differentiated lymphocytic lymphoma, small lymphocytic lymphoma, and splenic lymphoma with circulating villous lymphocytes) is a lymphoma made up of small B-cells that replace the normal architecture of the white pulp of the spleen.
