A Case of Ulcerative Colitis Complicated with Gonococcal Proctitis

A 35-year-old woman visited our hospital because of bloody diarrhea. At the other hospital she was diagnosed as ulcerative colitis (UC) 4 years earlier. She had been medicated SASP for 4 months until skin eruption was present. Since then she was followed by no medications. Two months before her consultation she noticed bloody diarrhea. A stool culture was positive for gonococcus. Colonoscopic examination disclosed reddish and granular mucosa from rectum to sigmoid colon and multiple ulcerative lesions in the rectum. Findings of much creamy pus in the rectum and ulcerative lesions near the anal canal may be particular features of gonococcal proctitis. A stool culture changed negative by taking antibiotics, but bloody diarrhea continued. She was improved with 5-ASA and topical steroid. We emphasize it is necessary to be ruled out infectious colitis even when considered exacerbation of UC.
