    Author: Nozoe T, Mori E, Iguchi T, Kohno M, Maeda T, Matsukuma A, Sueishi K, Ezaki T.
    Journal: Surg Today; 2013 Feb; 43(2):191-3. PubMed ID: 22610489.
    Abstract:
    We experienced a rare case of a pedunculated polyp of the appendix, which had been incidentally found by preventive appendectomy performed when providing surgical treatment for rectal carcinoma. A pathological investigation of this polypoid lesion demonstrated branches of fibro-muscular stalks connecting with the lamina muscularis covered by a hyperplastic mucosa, which proved to be consistent with the features of hamartoma. The patient had no external characteristics of Peutz-Jeghers syndrome, including mucocutaneous pigmentation and gastrointestinal polyposis, observed by endoscopy. This case is considered to be a Peutz-Jeghers type polyp of the appendix with a pedunculated form, which is very rare.
