An Intramucosal Mucinous Adenocarcinoma Arising From A Gastric Hyperplastic Polyp
نویسندگان
چکیده
Hyperplastic polyps are lesions that are mostly smaller than 1 cm; they are sessile and innocuous. They develop as a result of tissue damage and an exaggerated mucosal regeneration. Intestinal metaplasia and dysplasia at a rate of 1–20% may be seen in hyperplastic polyps. However, the risk of carcinoma development is less than 2%. The risk increases in multiple polyps (1). Here we present a case of an intramucosal mucinous adenocarcinoma that developed in a solitary hyperplastic polyp localized in the stomach antrum. There were extensive atrophic gastritis, intestinal metaplasia, and, interestingly, gastritis cystica profunda areas in the non-tumorous stomach.

Focal Intramucosal Adenocarcinoma Occurring in Gastric Hyperplastic Polyps: Two Case Reports
Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Two cases of intramucosal adenocarcinoma originating from gastric hyperplastic polyps that were successfully removed by endoscopic mucosal resection or endoscopic submucosal dissection are reported. On pathological examination, adenocarcinoma limited to the hyperplastic...

Here we report the first case of carbohydrate antigen (CA) 19-9-producing early gastric adenocarcinoma arising in polyp. A solitary pedunculated polyp lesion of the stomach, measuring 26 × 20 × 20 mm, was noticed in a 76-year-old Japanese woman due to an abdominal disorder, associated with a markedly high serum CA19-9 level (2,172.6 U/ml). After endoscopic mucosal resection was performed, the C...

We present herein the occurrence of multifocal adenocarcinomas with a minute signet ring cell carcinoma that arose within a gastric inverted hyperplastic polyp (IHP) in a 40-year-old woman. Endoscopic ultrasonography demonstrated a heterogeneous hypoechoic mass in the third layer of the gastric wall. The endoscopic submucosal dissection specimen measuring 3.5×3.2×1.8 cm was a well-circumscribed...

BACKGROUND Heterotopic gastric mucosa (HGM) is commonly seen in the upper esophagus during endoscopyand is generally considered a benign disease. A hyperplastic polyp and an adenocarcinoma arising in heterotopic gastric mucosa are quite rare occurences. CASE PRESENTATIONS We present two cases: The first is a patient who suffered from dysphagia because of a large hyperplastic polyp that arose ...
متن کاملA case of early gastric cancer coexisting with a hyperplastic polyp
A 52-year-old woman consulted a local physician because of epigastric pain. Upper gastrointestinal endoscopy showed a slightly elevated polyp, about 10 mm in diameter, in the anterior wall of the upper gastric body. The patient was therefore referred to the Department of Gastroenterology, Kitasato University East Hospital. Helicobacter pylori was negative, and there was no atrophy of the gastri...
