Multifocal Adenocarcinomas Arising within a Gastric Inverted Hyperplastic Polyp
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...

py for the investigation of lower abdominal pain. Colonoscopy showed a whitish, flat, elevated polyp, 10mm in diameter, in the ascending colon (l" Fig. 1). Endoscopic mucosal resection (EMR) was carried out, and the resected specimen histologically revealed both invasive cancer and serrated adenomatous glands coexisting in an inverted hyperplastic polyp (IHP) (l" Fig. 2a–c). A follow-up colonos...
متن کاملAn Intramucosal Mucinous Adenocarcinoma Arising From A Gastric Hyperplastic Polyp
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 cas...
متن کاملA Case of Gastric Inverted Hyperplastic Polyp Found with Gastritis Cystica Profunda and Early Gastric Cancer
A gastric inverted hyperplastic polyp is a rare type of gastric polyp and is characterized by downward growth of a variety of mucosal components into the submucosa. The polyp consists of columnar cells resembling foveolar epithelium and pyloric gland epithelium and can coexist with gastritis cystica profunda. Frequently, adenocarcinoma can coexist, but the relation is not clear. A 77-year-old m...
متن کاملA Rare Complication of Hyperplastic Gastric Polyp
Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric pol...
