Parietal cell hyperplasia with deep cystic dilations: a lesion closely mimicking fundic gland polyps.

TO THE EDITOR: Fundic gland polyps (FGPs) are multiple, small (2–5-mm), sessile polyps of the acid secreting gastric mucosa, described both in a sporadic form, prevalently in middle aged women (1) and associated with genetic familiar syndromes of the colon (2, 3). To date, their etiology remains unknown.
