An inverted hyperplastic polyp with a characteristic colonoscopic appearance.
A 65−year−old man was referred to our de− partment for polypectomy. A polyp, 20 mm in diameter, was found in the as− cending colon on colonoscopy (Figure1 a). The polyp surface was covered by charac− teristic multiple dimples, long thin ves− sels, and mucus. Chromoendoscopy with 0.4% indigo carmine enhanced the ap− pearance of the polyp surface dimples, and subsequent magnification revealed a t...
متن کاملIntramucosal Colon Cancer Developing in an Inverted Hyperplastic Polyp
Inverted hyperplastic polyps (IHPs) of the colon are unusual variant of exophytic hyperplastic polyps that are characterized by epithelial displacement or inversion of the epithelium into the submucosa. To date, only a few cases of IHPs associated with adenoma or adenocarcinoma have been reported. However, due to the rarity of these polyps, their malignant potential is poorly understood. A 56-y...
متن کاملInvasive cancer arising in a colonic inverted hyperplastic polyp.
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 کاملMultifocal 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...
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...
