Abstract
CASE REPORT An 81-year-old woman with a medical history of tobacco use and family history of colon cancer was referred for colonoscopy because of a reported weight loss of 25 pounds over 10 months. Colonoscopy revealed a 15 mm flat polyp in the ascending colon with a mucus cap (Figure 1). A submucosal injection of ORISE gel revealed a large whitish discoloration of the mucosa encompassing the polyp and surrounding mucosa (Figure 2). The polyp was removed with a cold snare in a piecemeal manner. Biopsy specimens of the surrounding mucosa revealed dilated lymphatics (4× magnification, hematoxylin and eosin stain) (Figure 3), which were interpreted as isolated colonic lymphangiectasia secondary to submucosal injection.Figure 1.: Flat polyp in the ascending colon with a mucus cap.Figure 2.: Large whitish discoloration of the mucosa encompassing the polyp and surrounding mucosa after submucosal injection with ORISE gel.Figure 3.: Colonic specimen (4× magnification, hematoxylin and eosin stain) showing dilated lymphatics.Primary intestinal lymphangiectasia is a rare disease of an unknown worldwide incidence that primarily affects the small intestine in children younger than 3 years, usually with other congenital abnormalities.1 However, it is increasingly being recognized in adults because of direct visualization of the small bowel with imaging modalities, such as capsule endoscopy and double-balloon enteroscopy.2,3 Isolated colonic lymphangiectasias are even more rare, and their clinical significance in an asymptomatic patient is unclear.
