Malignant lymphoma occurring simultaneously in the urinary bladder wall and bilateral renal parenchyma: A case report

Abstract

Abstract.A 67-year-old man was admitted to hospital with acid regurgitation, acute right lower abdominal pain and mild fever. Multiple suspicious mass lesions were detected in the patient's kidneys, the right side wall of his bladder and the right lower ureter, using CT urography and PET-CT. He underwent palliative surgery of the bladder and percutaneous renal biopsy. Postoperative histopathological examination and immunohistochemical staining indicated that the tumor was consistent with diffuse large B-cell lymphoma (DLBCL). Although DLBCL is by far the most common type of non-Hodgkin's lymphoma, it is rare for DLBCL to simultaneously involve the kidneys, bladder and the lower ureteric tract.

EBV-positive diffuse large B-cell lymphoma presenting as symptomatic masses in the bladder trigone and unilateral kidney

“…A case report by Min et al reports the occurrence DLBCL arising in the kidneys, ureteral tract, and urinary bladder. 4 Therefore, our patient's presentation with DLBCL simultaneously in the urinary bladder and left kidney is unique given the rarity of disease and multifocal growth.…”
