Background: Primary clear cell adenocarcinoma of the colon is a rare oncological entity. We report a case of such a tumor in the left colonic flexure of an 89-year-old patient who was treated surgically in our Department. We also review published cases which include primary colonic clear cell formations.
Case presentation: The patient sustained a segmental resection of the region [pT2 N0 (0/12) M0]. Histochemical examination indicated a primary clear cell colonic adenocarcinoma. The patient was discharged in good health but died from his disease 2 years later.
Results: Primary clear cell colonic adenocarcinoma is found exclusively in the left colon and generally in elderly men. From the few cases that have been published it is not possible to estimate the oncological impact of this tissue.
Conclusion: Even in advanced age surgical resection is the mainstay of the recommended treatment.
