Thymic derivatives should be included in the differential diagnosis of cystic masses in the neck. A classification of thymic cysts is proposed; namely, true, mixed, or false. Thymic cyst may contain cholesterol crystals in the luminal fluid, cholesterol clefts, granulomas, and lymphocytic follicles as well as Hassall corpuscles in the wall. Treatment consists of simple excision of the cyst and its accompanying tract. The 34th case of cervical thymic cyst in the English literature is reported.
