===Micro=== | |||
The sections show fibrous tissue consistent with a cyst wall lined by a simple columnar to flat epithelium, focally with cilia. | |||
Cautery is present imparting a pseudostratified appearance focally. No definite papillae or definite tufting is apparent. No significant nuclear atypia is seen. Mitotic activity is not apparent. | |||
