Clinical Course:

Follow-up EGD showed that mucosa of bulb and second portion was fragile and easily bleeding. Several polypoid lesion with ulcers were noted at post bulbar area s/p biopsy. After EGD, we changed to side-view endoscope. The papilla was invisible. Elevated lesion with fragile mucosa was noted at the ampular portion s/p biopsy.

Pathology:

The section shows duodenal mucosa with deposits of hyalinized material in lamina propria and mucosa muscularis.

Masson-Trichrome Stain





This case is consulted. Professor Shun in NTUH think this hyalinized material is amyloidosis as evidenced by positive Congo red stain. The case is unlike collagenous duodenitis, usually deposite in basement memberane area. So he suggestd to check the rectum or oral mucosa to rule out primary amyloidosis.

Small bowel enteroscopy and EUS





Follow-up evaluation :

Oral ulcer(-), arthritis(-),rash(-),photosensitivity(-),leg edema(-),Raynaud phenomenon(-),dry month or eye(-),back stiffness(-)

Intestine amyloidosis
