title: What is the clinicopathological characteristic of cloacogenic carcinoma outside the anorectal zone?
abstract: This study aimed to examine English-language publications on cloacogenic carcinoma which has developed outside the anorectal zone. Studies published in English literature on cloacogenic carcinoma developing in the colorectal area were accessed via Pubmed and Google scholar databases. Within these articles, studies in which there were developments in the other segments of the colon outside the anorectal zone were examined. We retrieved seven studies matching our selection criteria from the research. The studies were published between 1977 and 2009. Four of the patients were female and three were male; patient age ranged from 23 to 69 years. The anatomic tumors were in the sigmoid colon in four patients, and splenic flexure, descending colon and proximal rectum in one patient each. Four patients developed liver metastases. Basaloid carcinoma above the rectum is difficult to diagnose clinically. When suspected, the diagnosis can be made by immunohistochemical staining.
