Primary adenoid cystic carcinoma of the esophagus: a case report.

We report on the case of a 61-year-old woman with a pedunculated esophageal tumor that had a central ulceration. Histology of the resected tumor revealed adenoid cystic carcinoma which was localized entirely in the submucosal layer. The tumor was composed predominantly of solid nests of tumor cells, with some areas showing a cribriform pattern.
