[A Case of Late Recurrence in the Mesentery 25 Years after Surgery for Renal Cell Carcinoma]

An 81-year-old man was admitted with heart failure and severe anemia. He had undergone a right nephrectomy for renal cell carcinoma 25 years earlier. Abdominal CT revealed a transverse colon tumor. Colonoscopy showed a nearly circumferential lesion with submucosal tumor-like features. Laparoscopic transverse colectomy was performed, and the tumor was completely resected. Histopathological examination revealed a clear cell carcinoma consistent with recurrence of renal cell carcinoma. We report this rare case of late mesenteric recurrence 25 years after nephrectomy, along with a brief literature review.
