Primary renal lymphoma (PRL) is uncommon and a controversial manner due to lack of the lymphatic tissue in the kidneys. Less than 1% of the kidney lesions are PRL. We reported a 61-year-old female with abdominal and left flank pain. She had a large renal mass measured 19cm. The imaging, histopathology, and immunohistochemistry diagnosed the large mass as primary renal lymphoma, diffuse large B-cell type.
