We report a rare case of primary choriocarcinoma of the colon. A 58-year-old woman underwent Hartmann’s procedure to remove a sigmoid colon tumor, and pathological examination confirmed choriocarcinoma that had originated from the colon. Radical surgery combined with chemotherapy gives the best chance of long-term survival.
