Can Fundic Gland Polyps Occur in the Gastric Body?
Yes, fundic gland polyps (FGPs) characteristically occur in both the gastric fundus AND the gastric body (corpus)—this is their typical anatomic distribution. 1
Typical Location of FGPs
According to the British Society of Gastroenterology guidelines, FGPs are typically multiple, small (<1 cm) and located in the fundus and corpus 1. The guidelines explicitly state that "fundic glandular polyps seen in the corpus and body" are characteristic of this polyp type 1.
Recent research confirms this distribution pattern, noting that FGPs are primarily found in the gastric fundus and body 2. Multiple studies consistently document that these polyps develop in an area limited to the body and fundus of the stomach 3.
Key Clinical Points
When FGPs Are NOT in the Body/Fundus
Antral location should raise suspicion and prompt excision, as this is atypical for FGPs 1. The guidelines specifically state that "size of >1 cm, antral location, ulceration or an unusual appearance should question the diagnosis of FGP and lead to excision" 1.
Endoscopic Appearance in the Body/Fundus
When found in their typical location (body and fundus), FGPs appear:
- Pale, smooth, glassy, and transparent or translucent
- Either lighter or the same color as surrounding mucosa
- With lacy blood vessels visible through the translucent surface
- Surface pattern of fine grey dots 1
Clinical Significance
- Most FGPs are benign and not associated with increased cancer risk (except in FAP syndrome) 1
- Associated with long-term PPI use and can spontaneously regress when PPIs are stopped 1, 2, 4
- No association with H. pylori infection or gastritis 1
- FGPs >1 cm have been shown to be dysplastic in 1.9% and contain focal cancer in 1.9% 1
Management Implications
FGPs do not require excision unless they have atypical features 1. However, excision is warranted when polyps demonstrate:
- Size >1 cm
- Antral location (atypical)
- Ulceration
- Unusual appearance 1
There is no role for surveillance gastroscopy for FGPs, except in the setting of FAP 1.
