Abstract:
Colorectal carcinoma arises from the epithelium of the colorectal mucosa, and so it displays various macroscopic appearances with abnormal mucosal changes. But submucosal tumor-like colorectal carcinoma is very rare. We report here on two such cases along with a review of the relevant literature. The first case was submucosal tumor-like colorectal carcinoma that was initially diagnosed as rectal submucosal tumor, but the follow-up endoscopic exam revealed ulceroinfiltrative type adenocarcinoma. The second case was an endoscopically determined polypoid lesion combined with submucosal tumor, but it was found to be tubular adenoma with high grade dysplasia combined with a mucin pool collection in the submucosa after surgical resection.
