“…Few of these reports have described the endoscopic characteristics of these polyps in detail. The polyp in each of our three cases showed an irregularly lobular or nodular surface, whereas adenomas often show a regularly nodular or granular surface; this finding was compatible with previous reports [2,[5][6][7][8][9] . The color of the polyp was whitish in all of our cases, whereas previous reports have described the polyps to be red to normal color [6,7,9] .…”

“…A MEDLINE search of the English language literature revealed only nine well-documented cases of a solitary Peutz-Jeghers-type hamar tomatous polyp of the duodenum (Table 1) [2,[4][5][6][7][8][9] . Few of these reports have described the endoscopic characteristics of these polyps in detail.…”

“…A solitary Peutz-Jegherstype hamartomatous polyp is histologically characterized by tree-like branching of smooth muscle fibers, with a core of smooth muscle, covered by mucosal tissue of near-normal appearance [3] . A solitary Peutz-Jeghers-type hamartomatous polyp in the duodenum is rare, and few reports have described its characteristic endoscopic features [2,[4][5][6][7][8][9][10] . We describe three cases of solitary Peutz-Jeghers-type hamartomatous polyp and their endoscopic findings in detail.…”

A solitary Peutz-Jeghers-type hamartomatous polyp in the duodenum is rare, and few reports have described its characteristic endoscopic features. We describe three cases of solitary Peutz-Jeghers-type hamartomatous polyp and their endoscopic findings in detail. The polyp in all of our three cases showed an irregularly lobular or nodular surface, whereas adenomas often show a regularly nodular or granular surface. The color of the polyp was whitish in all of our cases. In the present cases, close observation by endoscopy revealed that the solitary Peutz-Jeghers-type hamartomatous polyps looked whitish because of the presence of diffusely scattered white spots on the surface of the polyps. Duodenal polyps that exhibit the aforementioned endoscopic characteristics may be diagnosed as Peutz-Jeghers-type hamartomatous polyps and treated by polypectomy because of the malignant potential.

“…A search of case reports on the MEDLINE database up to 2014 using the terms "solitary", "duodenum", and "hamartomatous polyp", but without PJS, identified 19 patients in 13 studies published in English with solitary-PJ type polyps in the duodenum, including the patient described here [2,[5][6][7][8][9][10][11][12][13][14][15] (Table 1). Age at onset ranged from 23-89 years (mean ± SD: 60.3 ± 20.1 years).…”

Solitary duodenal Peutz-Jeghers (PJ)-type hamartomatous polyps are rare and considered a different disease entity than classic PJ syndrome. We describe the case of an 89-year-old man admitted to our emergency department with symptoms of acute cholangitis, liver dysfunction, and slight jaundice. Magnetic resonance imaging showed multiple signal voids, reflecting choledocholithiasis, and an ovalshaped tumor in the common bile duct (CBD). Following endoscopic retrograde cholangiopancreatography, the patient was diagnosed with a lower CBD tumor 20 mm in diameter. Endoscopic sphincterotomy was performed for choledocholithotomy, resulting in the expulsion of a large tumor with a stalk connected to the papilla of Vater. The tumor was successfully excised en bloc by endoscopic snare papillectomy. Histopathologic examination showed that the tumor was a PJ-type hamartomatous polyp. No mucocutaneous pigmentation of the skin was evident and the patient's family history was negative. Solitary duodenal PJ-type hamartomatous polyps are usually diagnosed incidentally during endoscopy for other indications because most of these tumors are asymptomatic or have nonspecific presentations. To our knowledge, this is the first reported solitary PJ-type polyp with intra-CBD growth treated by endoscopic snare papillectomy.

Solitary duodenal hamartomatous polyp with malignant transformation: Report of a case

et al. 2009

A solitary duodenal hamartomatous polyp is rare and it is considered to be either a variant of Peutz-Jeghers syndrome (PJS) or a separate entity. Patients do not have cutaneous manifestations and have only one hamartomatous polyp. The presentation is nonspecific and it resembles common conditions, such as a peptic ulcer disease. Most are incidentally diagnosed during endoscopy for other indications. Malignant transformation has been reported. This report describes the case of a 46-year-old man who presented with chronic intermittent abdominal pain. The initial endoscopy showed an abnormal twisting of the duodenum with a dilated duodenum. He was later diagnosed to have a solitary duodenal hamartomatous polyp with malignant transformation, which was treated by surgery. A review of the literature on the pertinent cases of this type of lesion is also presented.
