Cervical ectopic thymus: a case report and review of the literature

Abstract

Ectopic cervical thymic tissue is rarely reported in medical literature, but it should be included in the differential diagnosis of neck masses, especially in children. The authors present the case of a young male with a soft right mid-cervical mass. The patient underwent complete excision of the lesion and histological examination showed an ectopic thymic cyst. The embryological development, clinical presentation and management of ectopic thymic lesions are discussed together with a review of the literature.
