title: Thymoma within a giant congenital thymic cyst.
abstract: Congenital thymic cysts are very rare and mostly asymptomatic mediastinal lesions. Thymoma within such cysts is even more uncommon and has so far hardly been described. We report on a 41-year-old male with a World Health Organization type B1 thymoma within the wall of a huge unilocular thymic cyst. Because of the possible coexistence of typical congenital thymic cyst and thymoma, we recommend surgical resection both for establishing the diagnosis and for definite treatment.
