Congenital bronchogenic sac cysts result from primitive foregut maldevelopment. Although they occur predominantly in the chest, they have been reported as extrathoracic lesions. Bronchogenic cyst diagnosis relies on lesion histology and location. We review our experience on the diagnosis and management of a 39-year-old man with pathologically proven bronchogenic cyst.
The cyst was surgically resected. Histologically, the cyst consisted of ciliated columnar epithelium, smooth muscle, and mucus glands, yielding a definitive diagnosis of bronchogenic cyst. This is the 18th case reported in the Japanese literature of a cervical bronchogenic cyst. In conclusion, congenital bronchogenic cysts may occur in the adult necks and should be considered in the differential diagnosis of cystic cervical masses.
