Abstract Primary squamous cell carcinoma (SCC) of the colon is a rare malignancy. The most reported anatomic location is the rectosigmoid colon. In this paper, we report a case of a 74-year-old man with primary SCC of the descending colon treated by surgery and adjuvant chemotherapy. We diagnosed primary SCC of the descending colon because except in the colon, no malignant lesions were found by systemic CT. The role of chemoradiation regimen and duration remains unclear due to the rarity of this entity.
