Spontaneous Regression of a Large Gastric Adenoma Following Gynecologic Surgery.

Gastric adenomas are defined as polypoid lesions of neoplastic epithelium in the stomach. They are rare, occurring much less frequently than fundic gland polyps and hyperplastic polyps, and are typically associated with mucosal atrophy and intestinal metaplasia. Gastric adenomas also carry a risk of malignant transformation. We report a case of a 66-year-old woman with a gastric adenoma of the corpus found during a preoperative esophagogastroduodenoscopy before abdominal surgery for an ovarian tumor. The patient demonstrated spontaneous regression of her gastric adenoma 14 months after her initial endoscopy and subsequent hysterectomy with salpingo-oophorectomy without undergoing endoscopic resection or any other intervention. To our knowledge, this is the first well-documented case of spontaneous regression of a gastric adenoma.
