[Congenital cysts and fistulas on the neck in adults]

Abstract

Cervical congenital malformations are relatively common in children. They can also be found in adults. The embryological development of the cervical region is closely related to the branchial clefts. This must be a diagnosis made by elimination; a cervical tumor must evoke the diagnosis of cancer. A cutaneous fistula or a cervical tumor, chronic or recent appearance in an inflammatory context, are the clinical signs. The thyroglossal duct cysts and the second branchial clefts cysts are the most common causes of median and lateral cervical cysts, respectively. Imaging contributes greatly to the orientation and diagnostic evaluation of the extent of the lesions. Treatment is initially based on antibiotic therapy and then on complete surgical excision, away from an infectious episode, the sole guarantee for the absence of local recurrence.
