(2023). A MALT LYMPHOMA PRESENTING WITH PRIMARY DIFFUSE RENAL INVOLVEMENT. Eskisehir Medical Journal, 4(Ek Sayı), 248-250.2718-0948https://hdl.handle.net/20.500.12713/6493The involvement of kidney in marginal zone lymphoma (MZL) is not a frequent condition. Seventy-seven year old female presented with renal failure. Renal biopsy revealed diffuse lymphoid infiltration replacing the normal renal tissue. Immunohistochemical staining was CD20, CD38, kappa, IgD positive and CD3, lamda, cyclin D1, CD5, CD23, CD43, lambda negative. Ki-67 was 10% positive. The patient was diagnosed as MALT type MZL. Body 18Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) performed for staging revealed diffuse FDG uptake in both kidneys and no lymphadenopathy was detected. Bone marrow aspiration and biopsy were normal. Rituximab-bendamustin chemotherpy regimen was started. In conclusion, this is the first case of MALT lymphoma involving kidney diffusely which requires rapid diagnosis and treatment to prevent irreversible loss of renal functions.eninfo:eu-repo/semantics/openAccessLymphomaMALT lymphomakidneyrenal involvementArticle4Ek Sayı24825010.48176/esmj.2023.142
