[Gastric bronchogenic cysts. An unusual location].

Bronchogenic cysts are rare benign lesions that arise during embryogenesis of the primitive proximal intestine and are located primarily in the lung. They are lined with cuboid or columnar pseudostratified and ciliated epithelium and have elastic fibers, smooth muscle, bronchial glands and cartilage in their walls. Gastric bronchogenic cysts are extremely rare with very few reported cases. Symptoms are usually caused by compression. GIST is the main differential diagnosis and the treatment is surgical resection.
