Iron deficiency anemia can be the first manifestation of colon cancer. However, iron deficiency anemia is also common in other benign conditions, which may cause a longer delay for referral decisions to get a definitive diagnosis. This is a case of 40-year-old male patient who had only iron deficiency anemia as a manifestation of colon cancer. Colonoscopy revealed intraluminal mass in transverse colon. After resection of the tumor, histopathology showed well-differentiated mucinous adenocarcinoma, invasion of sub-serous, and one node positive (pT3pN1pM0). After resection, we administered XELOX as adjuvant chemotherapy every 3 weeks for 8 cycles.
