ABSTRACT
Tubular duplication of the cervical portion of the esophagus was diagnosed in a 10-day-old female Quarter Horse. The foal was examined because of the development of a 12- to 15-cm diameter mass at the caudal aspect of the mandible after suckling. The foal was dyspneic when in lateral recumbency. Radiography and ultrasonography revealed a fluid- and gas-filled mass. Endoscopy revealed a normal-appearing upper airway and esophagus. Complete surgical resection of the mass was successful. The mass had a 3-mm diameter communication with the esophageal lumen at the pharyngoesophageal oriface. Histologic examination revealed stratified squamous epithelium lining the cyst-like cavity. The wall of the mass had circumferential and longitudinal layers of smooth muscle with few submucosal glands. The clinical, gross pathologic, and histopathologic findings were consistent with tubular duplication of the cervical portion of the esophagus.
