Abstract
We report a case of 76-year-old man, with a past medical history of primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT), who presented with ureteral tumor diagnosed as urothelial carcinoma on imaging investigations. Histological examination showed an unusual finding. The tumor was a ureteral localization of the PCDLBCL-LT previously diagnosed. To the best of our knowledge, this is the first case of PCDLBCL-LT with ureteral spread described in the literature.
