By contrast, two cases were CDX2 negative, with a gastric mucin phenotype, and H. pylori infection was not observed in the tumor or the surrounding mucosa. In these cases, a v-raf murine sarcoma viral oncogene homolog B1 (BRAF) mutation (V600E) was detected. ...

Gastric Hyperplastic Polyp with Xanthoma Observed by Magnification Narrow-Band Imaging Endoscopy and Endoscopic Ultrasonography : Report of a Case.
Fukuda S, Akahoshi K, Fushimi F, Oya M. Fukuda S, et al. Fukuoka Igaku Zasshi. 2015 Apr;106(4):77-82. Fukuoka Igaku Zasshi. 2015. PMID: 26117951 Free article. Review.
We experienced an extremely rare case of gastric hyperplastic polyp with xanthoma. A 73-year-old Japanese man was transferred to our hospital from a referral hospital for further evaluation of a pedunculated gastric polyp and early gastric cancer. ...The back …

Cyclooxygenase-2 expression and angiogenesis in gastric hyperplastic polyp--association with polyp size.
Kawada M, Seno H, Wada M, Suzuki K, Kanda N, Kayahara T, Fukui H, Sawada M, Kajiyama T, Sakai M, Chiba T. Kawada M, et al. Digestion. 2003;67(1-2):20-4. doi: 10.1159/000069708. Digestion. 2003. PMID: 12743436
In the present study, we attempted to examine the COX-2 expression pattern in gastric hyperplastic polyp, a non-tumorous lesion. PATIENTS AND METHODS: Fifty-eight gastric hyperplastic polyps, obtained by endoscopic polypectomy, were immunostained with anti-CO …

A white opaque substance-positive gastric hyperplastic polyp with dysplasia.
Ueyama H, Matsumoto K, Nagahara A, Gushima R, Hayashi T, Yao T, Watanabe S. Ueyama H, et al. World J Gastroenterol. 2013 Jul 14;19(26):4262-6. doi: 10.3748/wjg.v19.i26.4262. World J Gastroenterol. 2013. PMID: 23864793 Free PMC article.
The presence of a WOS in a gastric HP may be considered an endoscopic finding that is predictive of the neoplastic transformation of a gastric HP. We suggest that a WOS-positive gastric HP should be resected endoscopically to investigate its neoplastic transformation....

Hyperplastic polyps arising in autoimmune metaplastic atrophic gastritis patients: is this a distinct clinicopathological entity?
Zhang H, Nie X, Song Z, Cui R, Jin Z. Zhang H, et al. Scand J Gastroenterol. 2018 Oct-Nov;53(10-11):1186-1193. doi: 10.1080/00365521.2018.1514420. Epub 2018 Oct 24. Scand J Gastroenterol. 2018. PMID: 30353753
OBJECTIVES: Gastric hyperplastic polyp (GHP) commonly arises in the abnormal surrounding mucosa, including autoimmune metaplastic atrophic gastritis (AMAG). ...Gastroscopically, A-GHPs showed less distal and more multiple-region distribution in the stomach (p …

A gastric hyperplastic polyp observed endoscopically before and after autoamputation.
Nakajima T, Kamano T, Watanabe K, Meguro H, Shibasaki K. Nakajima T, et al. Endoscopy. 2003 Dec;35(12):1069-71. doi: 10.1055/s-2003-44592. Endoscopy. 2003. PMID: 14648422
To learn more about the mechanism(s) involved, it is important to observe a polyp just before and just after its disappearance. We report a case of a gastric polyp that was observed endoscopically just before and then just after autoamputation. ...

Xanthelasmas of the upper gastrointestinal tract.
Gencosmanoglu R, Sen-Oran E, Kurtkaya-Yapicier O, Tozun N. Gencosmanoglu R, et al. J Gastroenterol. 2004;39(3):215-9. doi: 10.1007/s00535-003-1288-3. J Gastroenterol. 2004. PMID: 15064997
The most common location of xanthelasmas was the stomach (76%), followed by the esophagus (12%) and duodenum (12%). All lesions were observed as yellow-white colored plaques at endoscopy. Multiple xanthelasmas were detected in 4 patients (24%); in the duodenum in 2, esopha …

Hyperplastic polyps were suspected based on white light endoscopic findings. Magnified endoscopy with narrow band imaging could not predict the coexistence of cancer. However, histopathological examination of the resected specimen revealed focal cancer at the surface of th …
