Cervical bronchogenic cysts in head and neck region.

Congenital cysts of the neck are not uncommon. Most of these are thyroglossal, branchial cleft and thymic cysts. Bronchogenic cysts are uncommon developmental anomalies of the tracheobronchial tree and rarely occur in the neck. More than 70 cases of bronchogenic cysts in the head and neck region have been reported in the literature. We report three cases presenting with neck swelling in the hyoid region that were diagnosed as bronchogenic cysts based on clinical and histopathological findings.
