From white points to yellow plaques: magnifying endoscopic features of duodenal lymphangiectasia

Polypoid Lymphangiectasia in the Sigmoid Colon: A Case Report of a Rare Entity

Intestinal polypoid lymphangiectasia is an uncommon disorder involving an improperly formed enteric lymphatic system. It is characterized by lymphatic vessel dilatation with impaired drainage or obstruction of the lymph from the intestine. In this report, we present a case of a 73-year-old male patient with chronic intermittent left lower quadrant abdominal pain for one year who was found to have a sigmoid colon polyp on a colonoscopy. Upon microscopic examination, the polyp revealed dilated lymphatic vessels staining strongly for D2-40 (lymphatic vessel marker), supporting the diagnosis of polypoid lymphangiectasia. Intestinal lymphangiectasia has a broad differential diagnosis, warranting histopathological examination for a definitive diagnosis.--------------.

Diagnostic value of intraoperative endoscopic examination in patients with intestinal lymphangiectasia: an analysis of 6 cases

AIM: To assess the diagnostic value of intraoperative endoscopic examination in patients with intestinal lymphangiectasia (IL).

METHODS: Six patients with IL and protein-losing enteropathy underwent intraoperative endoscopic examination during the study. Intraoperative endoscopic examination was performed via an intestinal incision to locate the site of lymph fluid leakage.

RESULTS: Endoscopic findings included white fluid in the intestinal lumen, multiple scattered white spots, and white and swollen villi in all the 6 patients, polyps in 3 patients, and mucosal erosion in 2 patients. After subserosal injection of methylene blue, the sites of lymph fluid leakage were successfully located in 5 patients (83.3%).

CONCLUSION: Endoscopic examination is a very important diagnostic test for patients with IL, especially for locating the site of lymph fluid leakage.
