A CASE IN WHICH VIDEO CAPSULE ENDOSCOPY WAS USEFUL FOR DIAGNOSIS OF ADVANCED JEJUNAL MUCINOUS CARCINOMA ASSOCIATED WITH PEUTZ-JEGHERS SYNDROME BEFORE SURGERY

Abstract

The patient was a 49-year-old. She had been diagnosed with Peutz-Jeghers syndrome during childhood. We diagnosed mucinous adenocarcinoma of the small intestine by several modalities including video capsule endoscopy and resected it surgically. Pathological examination showed that most of the tumor was composed of mucinous adenocarcinoma which was seen as a submucosal tumor on endoscopy. By video capsule endoscopy, we could see a papillary structure on part of the surface of the tumor and it was composed of papillary adenocarcinoma pathologically. Video capsule endoscopy may be useful for distinguishing histological types if the surface pattern of the tumor can be seen.
