A 73-year-old woman presented with chronic watery diarrhea and abdominal cramping of six weeks\u2019 duration. Biopsies of the colon revealed findings of collagenous colitis involving the endoscopically normal right colon, and superimposed collagenous and pseudomembranous colitis involving the rectosigmoid colon. Endoscopically, the left colon revealed discrete ulcerative plaques, and<jats:italic>Clostridium difficile<\/jats:italic>toxin A assay was positive. The patient partially responded to a three-week regimen of metronidazole, and symptoms resolved completely with subsequent steroid therapy. At follow-up endoscopy four months later, colon biopsies demonstrated persistence of subepithelial collagen but no pseudomembranes. The patient remained asymptomatic during this interval. Collagenous colitis has been reported in association with other inflammatory bowel diseases, including lymphocytic colitis, sprue and idiopathic inflammatory bowel disease. This unique association of collagenous colitis with an endotoxigenic inflammatory bowel disease is presented with a review of related disease features.<\/jats:p>","DOI":"10.1155\/2000\/350453","type":"journal-article","created":{"date-parts":[[2016,4,14]],"date-time":"2016-04-14T16:57:01Z","timestamp":1460653021000},"page":"353-358","source":"Crossref","is-referenced-by-count":26,"title":["Synchronous Occurrence of Collagenous and Pseudomembranous Colitis"],"prefix":"10.1155","volume":"14","author":[{"given":"Z","family":"Vesoulis","sequence":"first","affiliation":[{"name":"Department of Pathology, Summa Health System, Akron, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G","family":"Lozanski","sequence":"additional","affiliation":[{"name":"Department of Pathology, Summa Health System, Akron, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Loiudice","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Summa Health System, Akron, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","container-title":["Canadian Journal of Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2000\/350453.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2000\/350453.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,23]],"date-time":"2016-08-23T07:59:45Z","timestamp":1471939185000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cjgh\/2000\/350453\/abs\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2000]]}},"alternative-id":["350453"],"URL":"https:\/\/doi.org\/10.1155\/2000\/350453","relation":{},"ISSN":["0835-7900"],"issn-type":[{"value":"0835-7900","type":"print"}],"subject":[],"published":{"date-parts":[[2000]]}}}
