Marginal zone lymphomas are a heterogeneous subtype of indolent B-non-Hodgkin Lymphoma that includes three distinct diseases: Extranodal mucosa associated lymphoid tissue lymphoma, nodal marginal zone lymphoma and splenic marginal zone lymphoma lymphocytes +/- villous lymphocytes.
Nodal marginal zone lymphoma designates a group of lymphomas, possibly heterogeneous, that appear to originate in the marginal zone that surrounds the

In recent years, there have been several scientific advances that have helped improve the diagnosis of these conditions. Features in Children / Young Adults. 67% of marginal zone B cell lymphomas in children / young adults (up to age 29 years) are nodal, usually involving head and neck nodes. 80% male, usually no underlying disease. Excellent prognosis with low risk of recurrence.
Marginal zone B-cell lymphomas, also known as marginal zone lymphomas (MZLs), are a heterogeneous group of lymphomas that derive from the malignant transformation of marginal zone B-cells. Marginal zone B cells are innate lymphoid cells that normally function by rapidly mounting IgM antibody immune responses to antigens such as those presented by infectious agents and damaged tissues.

Marginal zone lymphomas are indolent B-cell lymphomas that putatively originate from the marginal zone of B-cell follicles, which can be found in the spleen, lymph node, and mucosal lymphoid tissues. The follicle consists of a germinal center surrounded by a corona that is divided into the mantle zone and the marginal zone. 2020-12-30 Splenic marginal zone lymphoma (SMZL) is a type of cancer (specifically a lymphoma) 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, ultimately invading the red pulp of the spleen. The multiple faces of marginal zone lymphomas.

The patient was diagnosed with marginal zone lymphoma (MZL) on histopathology of an extirpated lymph node. This report demonstrates an unusual case of a pleomorphic neoplastic population documented on cytologic evaluation that had moncytoid features and peripheral blood involvement; a previously undocumented IgG1 monoclonal gammopathy was also an interesting feature of this canine MZL.
Marginal Zone lymphoma (MZL) arises from defective b-cell lymphocytes. B-cells arise from the bone marrow and mature (differentiate) into many cell types that tend to migrate to different areas of the body in order to defend against pathogens (viruses, bacteria, etc.). BACKGROUND.: Prognostic factors and outcomes in patients with marginal zone lymphoma (MZL) have been studied in small cohort studies, which may not reflect the population at large. METHODS.: Clinical characteristics and survival outcomes of adult patients with MZL who were diagnosed between 1995 and 2009 were evaluated using the Surveillance, Epidemiology, and End Results (SEER) database.
