Erika Tsuchiyose, Michael Talanian, Erik Holzwanger
TL;DR
The paper discusses a rare case where endoscopic ultrasound was used to diagnose lymphoma in the kidney.
Contribution
It presents a novel application of endoscopic ultrasound for renal tissue sampling in a complex patient case.
Findings
Endoscopic ultrasound can overcome limitations of traditional imaging for renal mass evaluation.
A case of renal lymphoma was successfully diagnosed using endoscopic ultrasound-guided tissue acquisition.
Abstract
Mucosa-associated lymphoid tissue lymphoma is a subtype of non-Hodgkin lymphoma, exceedingly rare when originating in the kidney. Most renal masses are percutaneously sampled with ultrasound or computed tomography guidance; however, limitations can include location, size, and body habitus, which may be resolved using endoscopic ultrasound–guided approaches. We present an unusual case of a 77-year-old man with history of systemic lupus erythematosus, duodenal mucosa–associated lymphoid tissue lymphoma in remission, and rectal adenocarcinoma who presented for evaluation of a right renal mass, which highlights the novelty of endoscopic ultrasound–guided renal evaluation and tissue acquisition.
