Cervical thymic cyst: A rare cause of neck mass in a female adolescent

Cervical thymic cysts are an uncommon cause of a neck mass in children. Most cervical thymic cysts undergo surgical excision for diagnostic purposes; therefore, the natural progression of these lesions is not known. While these lesions are more predominant in males, we present a 15-year-old female who underwent an uneventful surgical excision of a cervical thymic cyst.
