title: Cystic thymoma.
abstract: Thymic cysts are rare lesions located along the anatomical course of the third pharyngeal pouch. While most of the cases represent congenital cysts, they may also be related to neoplasms. We report a case of a micronodular thymoma with lymphoid stroma, which was completely built of small cysts, discuss the pathologic features of this tumor type and review the etiology and other aspects of thymic cysts.
