Low-Grade Extranodal Marginal Zone B Cell Lymphoma of Malt in the Kidney
نویسندگان
چکیده
Primary renal lymphomas are very rare since renal involvement by the disease is most often a manifestation of disseminated disease. We report an 88-year-old man with low-grade extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT) (MALT lymphoma) arising in the kidney. After the workup, the patient was thought to have renal cell carcinoma and underwent partial nephrectomy. The pathologic evaluation showed a MALT lymphoma. No additional treatment was given, and the patient was disease free during the follow-up.

Extranodal marginal zone lymphoma of MALT involving the lungs, the stomach, and the colon.
Extranodal marginal zone lymphoma of MALT, previously known as MALT lymphoma, is a low grade B-cell Non-Hodgkin's lymphoma (NHL). Its most frequent locations are the gastrointestinal tract and the lungs while that of the colon is rare. Involvement of multiple mucosal sites is not a frequent finding but it does occur. We describe a case of a 70-year-old man who presented with extranodal marginal...

We describe a rare case of extranodal marginal zone/low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) combined with areas of well-differentiated adenocarcinoma. In addition, the MALT lymphoma was synchronously systemic, with involvement of the lung, stomach and duodenum.
متن کاملMucosa-Associated Lymphoid Tissue (MALT) Lymphoma
Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is an extranodal lymphoma composed of morphologically heterogeneous small B-cells including marginal zone (centrocyte-like) cells, cells resembling monocytoid cells, small lymphocytes, and scattered immunoblasts and centroblast-like cells. There is plasma cell differentiation in a proportion of the cases. The...
متن کاملCD40 Ligand and Autoantigen Are Involved in the Pathogenesis of Low-Grade B-Cell Lymphomas of Mucosa-Associated Lymphoid Tissue
Low-grade MALT-type lymphomas are malignancies of mucosal marginal-zone B cells and preceded by reactive inflammatory lymphoid tissue. Experimental observations suggest that antigen and CD40 Ligand act during cognate T/B cell interaction and are crucial for germinal center B-cell maturation generating marginal-zone B cells. To investigate the mechanisms underlying the development of extranodal ...

Extranodal marginal zone B-cell lymphoma is a discrete clinicopathological entity arising in mucosa-associated lymphoid tissue (MALT) that has commanded increasing attention in recent years because of its unique pathogenetic, histologic, and clinical features.1-3 Two types of MALT can be identified in disparate organs that do not correspond to peripheral sites of the immune system. The native t...
