Primary mucosa-associated lymphoid tissue-type lymphoma arising in the kidney.
We report a case of primary low-grade lymphoma of mucosa-associated lymphoid tissue (MALT) arising from the kidney in a 30-year-old man with an abdominal mass in the right flank detected by ultrasonography. Radical nephrectomy was performed under a preliminary diagnosis of renal cell carcinoma. The final histological diagnosis was MALT-type lymphoma. To the best of our knowledge, only five reports of primary MALT-type lymphoma in the kidney have been published in the literature so far. All cases were surgically treated and only one case went on to chemotherapy postoperatively.
