Abstract:
:Peutz-Jeghers syndrome is a malignancy-associated polyposis syndrome. We describe a histopathologic phenomenon easily encountered when examining the nature of Peutz-Jeghers polyps but that is underreported in the literature. This phenomenon of "pseudo-invasion" may mimic invasive carcinoma due to epithelial displacement and erroneously give the impression, both macroscopically and microscopically, that a malignancy is involved. This potential pitfall is illustrated by the case of a patient with Peutz-Jeghers syndrome who was thought to harbor a metastasizing adenocarcinoma in his small bowel with peritoneal metastasis as a perioperative finding. Histologic examination, however, revealed pseudo-invasion.
