  • Title: Gastric hamartomatous polyp without polyposis coli: radiologic diagnosis.
    Author: Sato T, Sakai Y, Ishiguro S, Fujita M, Kuriyama K, Narumi Y.
    Journal: Gastrointest Radiol; 1988; 13(1):19-23. PubMed ID: 3350263.
    Abstract:
    Gastric hamartomatous polyps were found in 25 patients over a period of 4 1/2 years, for an incidence of 11% in all endoscopically biopsied polyps. The number of polyps was fewer than 5 in most patients. All polyps were sessile, sharply demarcated, hemispheric protrusions, measuring up to 10 mm in diameter but most were less than 5 mm. The most characteristic finding differing from hyperplastic polyps, adenoma, and polypoid carcinoma was that hamartomatous polyps were located in the fundic gland mucosa, which was demonstrated as a rugal area on moderately distended double-contrast radiographs.
