“…Recently new endoscopic findings have been added: red spots [13] , aphthoid ulcer [14] , ulcer [6] , mucosal tears [15,16] , hemorrhagic lacerations [17] , and longitudinal ulcers [18] . In our case, distinct diffuse cloudiness of the mucosa was observed on two occasions in this patient with collagenous colitis.…”

There have only been a few reports on lansoprazoleassociated collagenous colitis. Colonic mucosa of collagenous colitis is known to be endoscopically normal. We present a case of collagenous colitis where the mucosa showed diffuse cloudiness mimicking ulcerative colitis. A 70-year-old woman developed watery diarrhea four to nine times a day. She had interstitial pneumonia at 67 and reflux esophagitis at 70 years. Lansoprazole 30 mg/d had been prescribed for reflux esophagitis for nearly 6 mo. Lansoprazole was withdrawn due to its possible side effect of diarrhea. Colonoscopy disclosed diffuse cloudiness of the mucosa which suggested ulcerative colitis. Consequently sulfasalazine 2 g/d was started. The patient's diarrhea dramatically disappeared on the following day. However, biopsy specimens showed subepithelial collagenous thickening and infiltration of inflammatory cells in the lamina propria, confirming the diagnosis of collagenous colitis. One month after sulfasalazine therapy was initiated, colonoscopic and histological abnormalities resolved completely. Five months later the diarrhea recurred. The findings on colonoscopy and histology were the same as before, confirming a diagnosis of collagenous colitis relapse. We found that the patient had begun to take lansoprazole again 3 mo ahead of the recent diarrhea. Withdrawal of lansoprazole promptly resolved the diarrhea. Endoscopic and histological abnormalities were also completely resolved, similar to the first episode. Retrospectively, the date of commencement of sulfasalazine and discontinuation of lansoprazole in the first episode was found to be the same. We conclude that this patient had lansoprazole-associated collagenous colitis.

“…[1][2][3][4][5] We report here a case of depressed-type, early duodenal carcinoma treated successfully by endoscopic mucosal resection (EMR). A depressed-type tumor, approximately 4 mm in diameter, was detected endoscopically in the descending duodenum of a 53-year-old man during routine physical examination.…”

“…The endoscopic findings of CC are thought to be normal or nonspecific, 1,3 but several case reports have demonstrated unusual endoscopic findings, such as edema, 3,4 diminished vascular transparency, 2,3 multiple red spots, 5 and hemorrhagic mucosal disruptions. 6 All of these findings were considered to be uncommon.…”

“…Most patients with CC have a benign clinical course . Endoscopically, the colorectal mucosa usually appears normal in patients with CC, although non‐specific findings such as erythema, edema, or an abnormal vascular pattern have been reported in up to 30% of cases . Some patients with CC may be misdiagnosed with irritable bowel syndrome because of normal endoscopic findings .…”
