A 59-year-old woman was diagnosed with primary intestinal lymphangiectasia (PIL), with characteristic findings on capsule enteroscopy and confirmation by histopathological examination of biopsy specimens. We viewed the abnormal jejunal mucosa using a newly developed magnifying single-balloon enteroscope (SIF-Y0007). Conventional observation showed leakage of chyle. However, using this new scope, we could see scattered white villi, representing dilated lymphatic vessels within the intestinal villi protruding from the dilated submucosal lymphoid vessels (D2-40 positive) within an edematous jejunal lesion. This report is the first to describe the white villi in a patient with PIL observed clearly using a newly developed magnifying enteroscope. Technological advancements and the accumulation of reported pathological data would further improve our understanding of the pathophysiological aspects of this disease entity, even in the jejunum.
