Two Cases of 18F‐FDG‐PET/CT Positive Schloffer Tumor Following Curative Surgery of Colon Cancer

We report two cases of Schloffer tumor that required resection after radical colon cancer surgery because of suspected lymph node recurrence on contrast-enhanced (CE) CT and 18F-FDG-PET/CT. Case1 is a 69-year-old man with sigmoid colon cancer pStage IIA, and case2 is a 61-year-old man with descending colon cancer pStage IIIB.
