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. Although the Schloffer tumor is rare, it can be misdiagnosed as a solitary metastatic cancer recurrence. We should be aware of the presence of this tumor and be cautious to avoid futile chemotherapy.
