A 56-year-old woman was seen with an abnormal shadow on chest radiogram. Evaluation revealed an esophageal tumor, which was resected. The tumor was found in the muscular layers of the esophagus; esophageal schwannoma was diagnosed by light microscopic and immunohistochemical studies. There was no relationship between the tumor and vagus nerve. The tumor demonstrated partially invasive growth, and mitotic figures were occasionally observed.
