A Rare Case of Inverted Lymphoglandular Colonic Polyp

Nodular hyperplasia of lymphoglandular complexes in dogs: A potential diagnostic pitfall for rectal masses

“…Similar masses containing varying proportions of epithelial and lymphoid components have been reported rarely in the human literature, 9,15,19 though some of these cases are more consistent with inverted adenomatous polyps or submucosal herniation of colonic glands than primary proliferation of the lymphoglandular complexes. The case documented by Zhou et al, designated an inverted lymphoglandular polyp, bears closest resemblance to the lesions described here, but the arrangement of the epithelial component was slightly different, comprising sparse, irregular ectatic glandular structures rather than the small, contorted tubuloacinar foci observed in these dogs.…”
