Synchronous early primary adenocarcinoma of both rectum and gallbladder. Report of a case.
BACKGROUND
Synchronous early primary cancers are rare and in addition synchronous adenocarcinoma of both rectum and gallbladder is extremely rare.


METHODS
We report an unusual case of synchronous early primary adenocarcinoma of rectum and gallbladder. The patient was a 72-year-old woman with complaints of bloody stools and constipation. An endoscopy revealed adenocarcinoma of the lower rectum. A through preoperative investigation showed also cholelithiasis. The patient underwent abdominoperineal resection and cholecystectomy. The histopathological diagnosis was well to middle differentiate adenocarcinoma of the gallbladder (T2, N0, M0; stage II) and middle differentiate adenocarcinoma of the rectum (T2, N0, M0; stage II).


CONCLUSIONS
For the cases of extracolonic primary cancer associated with colorectal primary carcinoma, Warren and Gates' diagnostic criteria are used. All patients with colorectal carcinoma, should undergo a throughout preoperative examination to exclude the possibility of synchronous early primary cancers.
