Pyloric Gland Adenoma of the Esophagus Treated by Endoscopic Submucosal Dissection: A Case Report

Pyloric Gastric Adenoma: Endoscopic Detection, Removal, and Echoendosonographic Characterization

Pyloric gland adenomas (PGAs) are rare neoplasms found not only in the gastrointestinal tract but also in other extragastrointestinal organs. They have potential for malignant conversion, and early detection and removal is imperative to prevent invasive disease. PGAs prove difficult in management and surveillance given their rarity. However, increasing familiarity with histological appearance and use of advanced tools such as echoendosonography can bring greater understanding of their clinical history. We describe a unique case of a PGA detected within a hiatal hernia sac characterized with echoendosonography and highlight the need to develop surveillance protocols for these types of lesions.

Multifocal Pyloric Gland Adenoma of the Esophagus Treated by Circumferential Endoscopic Submucosal Dissection

Pyloric gland adenoma is a rare neoplasm of the gastrointestinal tract typically observed in the stomach with a substantial malignant potential warranting its resection. While isolated esophageal pyloric gland adenoma has been reported, there is no literature on the encounter of diffuse, multifocal esophageal pyloric gland adenoma or its management. We present a unique case of multifocal pyloric gland adenoma of the esophagus treated by circumferential endoscopic submucosal dissection. We demonstrate endoscopic submucosal dissection to be a feasible management option.
