A barium granuloma of the colon and rectum is a rare complication of radiologic examination of the digestive tract using barium. This complication is exceptional. During the enema, the cannula may ulcerate the mucosa which is blown up secondarily by the barium. Clinically, the granuloma presents as a hard polyp like a malignant tumur. So, the recognition of this entity is important because it can mimic other lesions including a neoplastic process endoscopically. Moreover, hisological findings, though they may be characteristic, often go unnoticed with routine techniques only. The authors report a barium granuloma of the rectum which was diagnosed by endoscopic mucosal resection and radiographic study of the paraffin block.

A squamous cell papilloma of esophagus is regarded as a rare tumor, and one of the distal esophagus is known to be not changed into a malignant neoplasm although squamous papilloma of the larynx, cervix and the upper esophagus may be associated with squamous cell carcinoma. We report the first case of a squamous papilloma associated with hig grade dysplasia at the lower esophagus. We think this case may have an important implication in the surveillance and management of esophageal papilloma found at endoscopy.
