[Cervical thymic cysts are a rare cause of neck masses in children and adolescents].Ugeskr Laeger. 2014 Oct 06; 176(41)UL
Cervical thymic cysts are rare benign unilateral lesions of the neck most often diagnosed in male children less than ten years of age. To date, less than 200 cases have been described. We report a case with a typical presentation in an 8-year-old boy. To our knowledge this is the first reported case in Denmark for almost three decades. Cervical thymic cysts represent a clinical challenge as no diagnostic non-invasive test or imaging is available. The cyst was successfully removed by surgical excision and a final histological diagnosis obtained.
