[Secondary primary, bilocal sigmoid colon adenocarcinoma in a patient previously treated for testicular cancer].

Frequency of neoplastic diseases among patients cured successfully from testicular cancer is higher than in normal population. Synchronous occurrence of neoplasms in those patients is a rarity. The case of simultaneous adenocarcinoma of ascending and sigmoid colon in a man effectively treated before for testicular cancer is presented. The patient underwent nearly total colectomy and resection of the rectal polyp. Six months after operation patient did not present any features of neoplastic disease. This case is an illustration of the problem of cancerogenesis within polyps of the large bowel in patients treated before by chemotherapy because of testicular cancer.
