<原著>食道嚢腫の一例

Abstract

A Case of esophageal cyst was reported with literature of genesis and comparison with bronchogenic cyst. A 57 year old female consulted our hospital because of abnormal shadow on chest x-ray with no symptom. Tomography and chest CT revealed a clear defined mass attached to the wall of esophagus and it was treated surgically. The presence of well defined double layers of smooth muscle with no cartilage and stratified ciliated columnar epithelium, stratified sqamous epithelium was observed, and then, the tumor was diagnosed as esophageal cyst. Among many embryological theories, this type of cyst was mainly thought to arise as a result of persistent vacuoles in the wall of the foregut. Because the main purpose of the surgical treatment of esophageal cyst is exclusion of symptoms or diagnosis, operation should be limited within no residual complications such as esophageal stenosis and so on.
