Intestinal tuberculosis is a common disease of extrapulmonary tuberculosis and should be differentiated from the inflammatory bowel diseases and malignancy such as Crohn's disease, ulcerative colitis, amebic colitis, and colon cancer. Most frequently involved sites (75% of cases) are the terminal ileum and cecum. Other sites of involvement, in order of frequency, are ascending colon, jejunum, appendix, duodenum, stomach, esophagus, sigmoid colon, and rectum. Intestinal tuberculosis simultaneously involving the stomach and colon has been very rarely reported. Recently, we experienced a case of synchronous gastric and colonic ulcers with granulomatous inflammation. Although we did not find acid fast bacilli and the culture test was negative, empirical anti-tuberculosis therapy resulted in dramatic clinical and endoscopic improvement. We report a rare case of multifocal gastrointestinal tuberculosis with a review of literature.

Lower gastrointestinal complications often develop in end stage renal disease patients, and among the more problematic is recurrent colon ulcer. The exact pathogenesis of this condition is not known and there were no specific therapeutic modalities concerning this type of disease entity. We report, with a literature review, a case of recurrent colon ulcer with intermittent hematochezia in an end stage renal disease patient on long term hemodialysis that improved after conversion to peritoneal dialysis.

We experienced a rare case of colonic cryptococcosis in an apparently immunocompetent individual. A 27-year- old woman admitted our hospital for intermittent melena. Initial abdominal CT scan revealed a mass lesion obstructing most of the lumen in ascending colon. Colonoscopy showed huge ulcerofungating mass in proximal ascending colon. Colonoscopic biopsy was performed and pathologic diagnosis was made as colonic cryptococcosis with positive PAS stain. Laboratory test evaluating immune status and bone marrow examination was normal. The patient was treated with intravenous amphotericin B for four weeks and six months of oral fluconazole afterwards. Follow-up abdominal CT scan and colonoscopy were taken at four weeks and seven months after the beginning of treatment. On completion of intravenous amphotericin B treatment, the mass lesion was decreased in abdominal CT and colonoscopy. After seven months, abdominal CT and colonoscopy showed near-complete resolution of the colonic lesion so the treatment ended. Cryptococcosis in a healthy individual is a rare disease and there have been only several sporadic case reports on pulmonary or central nervous system involvement. Hence, we report a case of colonic cryptococcosis in an apparently immunocompetent individual.

Malakoplakia is a rare granulomatous disease that occurs commonly in the urinary tract and secondarily in the gastrointestinal tract. Most reported cases of malakoplakia are associated with immunosuppressive diseases or chronic prolonged illness. Here, we report a rare case of malakoplakia in a young healthy adolescent without any underlying disease. A 19-year-old female was referred to our hospital following the discovery of multiple rectal polyps with sigmoidoscopy. She had no specific past medical history but complained of recurrent abdominal pain and diarrhea for 3 months. A colonoscopy revealed diverse mucosal lesions including plaques, polyps, nodules, and mass-like lesions. Histological examination revealed a sheet of histiocytes with pathognomonic Michaelis-Gutmann bodies. We treated the patient with ciprofloxacin, the cholinergic agonist bethanechol, and a multivitamin for 6 months. A follow-up colonoscopy revealed that her condition was resolved with this course of treatment.
