Ureteral metastasis as the first and sole manifestation of gastric cancer dissemination
Background. Isolated ureteral metastasis from gastric cancer is extremely rare.
Case report. We describe a 50 year old man with a history of subtotal gastrectomy who presented 4 years later with an ureteral metastasis. He was asymptomatic and diagnostic tests were performed due to the elevated creatinine level disclosed incidentally. The partial resection of distal right ureter as well as the resection of the right ureterovesical junction was performed with the implantation of double J stent. Histopathology revealed a metastasis of the adenocarcinoma that matched perfectly a tumour specimen from the gastric cancer surgery. It was first and isolated manifestation of gastric cancer dissemination.
Conclusions. Although rare, the ureteral metastasis from gastric cancer can be the first, sole and asymptomatic manifestation of gastric cancer dissemination after a period of time.
