[Neck bronchogenic cyst. Case report and review of the literature].
BACKGROUND
Bronchogenic cyst is a malformation of the ventral portion of the intestine, which is limited by bronchial epithelium and produces alterations in the development of the tracheobronchial tree. They may be single or multiple, and are usually confined to one lung or to the mediastinum, rarely to the neck, which is a subcutaneous tissue.


OBJECTIVE
The case of a 9 year old girl is reported, who presented with a clinical picture characterized by a slow-growing, asymptomatic tumour on the left side of the neck of 4 years onset. Chest X-ray, neck ultrasound and computed tomography of the neck and chest ruled out any other injury. A complete resection was performed, and the histopathological study confirmed the diagnosis of bronchogenic cyst.


CONCLUSIONS
The symptomatology of a bronchogenic cyst is due to the compression of the vascular, digestive or air structures, as well as its size, infection and location. The treatment of choice is a surgical resection, even when asymptomatic.
