[Tumor in the small intestine in Peutz-Jeghers syndrome].
Epithelial misplacement can be present in small bowel polyps of patients with Peutz-Jeghers syndrome and can mimic invasive malignancy. For recognizing epithelial misplacement, which can also have dysplastic changes, it is helpful to demonstrate the associated lamina propria and the lack of desmoplastic response. Intramural mucinous cysts are frequently seen in the setting of epithelial misplacement.
