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.
十二指肠中孤立的黑斑息肉病样错构瘤性息肉很罕见，很少有报告描述其特征性的内镜表现。我们详细描述了3例孤立的黑斑息肉病样错构瘤性息肉及其内镜检查结果。我们3例患者的息肉均表现为表面不规则分叶状或结节状，而腺瘤通常表现为表面规则的结节状或颗粒状。我们所有病例中息肉的颜色均为白色。在本病例中，内镜密切观察发现，孤立的黑斑息肉病样错构瘤性息肉呈白色是因为息肉表面有散在的白色斑点。表现出上述内镜特征的十二指肠息肉可被诊断为黑斑息肉病样错构瘤性息肉，因其有恶变潜能，可行息肉切除术治疗。
