An unusual localization of localized colitis cystica profunda in a 31-year-old man is described. The patient presented as anal bleeding and a protruding mass at the descending colon; the mass was polypoid and was made up of papillary epithelial hyperplasia with downward herniation of glands into the submucosa. Only one similar case involving a descending colon has been reported in the world literature.

We report one such case which was diagnosed intraoperatively as left dorsal colon volvulus due to multiple mesenteric abnormalities. A 17-year-old castrated male horse was taken to the Tehran University Veterinary Hospital for treatment of metacarpal wound accompanied by severe abdominal distension and acute colic. The treatment and measurement were taken for a month, and the prepared biopsy indicated that the healing trend was obvious. Unfortunately, prior to discharge, the clinical colic manifestations emerged and the animal suddenly died. Dilated large intestine was palpated per rectum and a ventral midline exploratory laparotomy was performed, a complete volvulus of the ascending colon was identified with multiple mesenteric anomalies of unknown aetiology. The pathologic changes observed in this study accurately reflect those changes reported in horse with naturally occurring colonic volvulus and can serve as a reference for subsequent studies on attenuating bowel injury. The present study results can be used to make a scientific assessment of prognosis in the pre-operative, operative, and post-operative management of horses with large colon volvulus.

A 24-year-old lady with recurrent upper abdominal pain, underwent surgery for cholelithiasis based on imaging diagnosis by ultrasound scanning. At laparotomy, the gall bladder could not be found either in its normal or ectopic locations. The diagnosis of agenesis of the gall bladder was confirmed by operative cholangiography. Duplication cysts of the hepatic flexure were discovered in the position normally occupied by the gall bladder. The stony hard faeces in the cysts were probably interpreted as gallstones on ultrasound. This rare condition is discussed and the importance of intraoperative cholangiography is stressed.

Colonic hamartomas are rare polypoid lesions. We report an unusual case of multiple colonic hamartomatous polyps, including a giant hamartoma, unrelated to hereditary or familial polyposis syndromes, in a 48-year-old man. The diameter of the largest polyp was 9.5 cm, and endoscopy revealed that the lesion caused colonic obstruction. The clinical, endoscopic and histological aspects of this case are discussed.

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple gas filled cysts in the intestinal wall. The diagnosis of PCI is usually made by colonoscopy, histology, or radiologic findings. We report a case of PCI in a 35-year-old man. The patient initially complained of watery diarrhea and abdominal bloating for 2 weeks. Simple abdominal X-ray demonstrated numerous, small, round, air densities on the right upper abdomen along the ascending and proximal transverse colon. Colonoscopy revealed numerous, 5-20 mm sized, sessile polypoid, balloon-like distended, protruding subepithelial masses covered with normal colonic mucosa from cecum to proximal transverse colon. We performed a CT colonoscopy and confirmed PCI with multiple air-filled cystic masses along the colonic wall from cecum to proximal transverse colon. The patient was treated with antibiotics and oxygen inhalation for 2 weeks. Follow-up CT colonoscopy revealed marked regression in the number and size of the air-filled cystic masses. Herein, we report the first case of the PCI in Korea diagnosed by CT colonoscopy. Follow-up evaluation with CT colonoscopy was performed after the treatment of the PCI. CT colonoscopy is a useful non-invasive diagnostic tool for the diagnosis of pneumatosis cystoides intestinalis.

A 50-year-old Chinese man presented with abdominal pain associated with bloody mucoid stools, loss of appetite and weight loss. Contrast-enhanced computed tomography of the abdomen and pelvis revealed a colocolic intussusception secondary to a lipoma. The patient subsequently underwent a left hemicolectomy. Clinical and imaging findings of intussusception in adults are discussed in this article.

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.

We report a case of a 72-year-old woman with Churg-Strauss syndrome, who presented with intestinal perforation. She has had bronchial asthma with peripheral blood eosinophilia for 30 years. Gross findings of a resected colon showed multiple ulcers with perforation. Histologic findings demonstrated transmural inflammation infiltrated with large numbers of eosionophils, neutrophils and lymphoplasma cells, and characteristic extravascular granuloma in the subserosa. There were multifocally-distributed transmural vasculitis showing all stages of activity in medium and small-sized arteries and veins located in the submucosa, and proper muscle and subserosal layers of the colon, some of which revealed granulomatous inflammation. Histologic finding of liver showed chronic viral hepatitis B with mild inflammatory activity and macronodular cirrhosis. Immunohistochemical findings, acid fuschin orange G staining and electromicroscope found no evidence of hepatitis B virus infection contributing to the pathogenesis of this lesion.

Primary adenosquamous carcinoma of the liver is generally considered as an extremely rare subtype of cholangiocarcinoma. It has been reported mostly in a form of case studies. As far as we know, there was only one case report on tumor related with biliary fistula. Recently, we experienced a case of primary adenosquamous carcinoma of liver with a formation of tumor-colonic fistula. A 54-year-old man was transferred to our hospital due to liver mass detected by abdominal ultrasonogram. Dynamic computed tomogram of liver showed a large irregular hypodense mass without rim enhancement in right lobe of liver and also suggested a fistula formation between the tumor and hepatic flexure of right colon. Colonoscopic examination showed a large colonic wall defect in hepatic flexure and a friable, nodular mucosa around the defected colonic wall. Extended right lobectomy and right hemicolectomy were done. Microscopically, the tumor was composed of squamous cell carcinoma mainly with foci of the adenocarcinoma component.
