Tailgut cyst initially misdiagnosed as ovarian tumor.

INTRODUCTION: Tailgut cyst (retrorectal cystic hamartoma) is an uncommon congenital lesion that arises from remnants of the embryonic post-anal gut. It is usually benign and located in the retrorectal/presacral space. CASE REPORT: A 45-year-old woman presented with lower abdominal discomfort, urinary frequency and right-sided pelvic mass. Digital rectal examination and computerized tomography scan demonstrated a multicystic complex mass occupying the region of the right ovary and extending into the retrorectal/presacral space. The initial diagnosis was neoplasm of the right ovary. At laparotomy, the mass was lying free from apparently normal internal genital organs. Excision of the mass from the right pelvis and retrorectal/presacral space and total abdominal hysterectomy were performed. Microscopic examination revealed that the wall of the cystic mass consists of a lining epithelium composed of columnar and squamous epithelium and a stroma composed of fibrous tissue containing scattered discontinuous bundles of smooth muscle fibers. Based on these histological findings, the final diagnosis was tailgut cyst. CONCLUSION: Tailgut cyst is an uncommon entity that should be included in the differential diagnosis of retrorectal/presacral mass. The treatment of choice is complete surgical excision.

Primary aortoduodenal fistula: Pitfalls and success in the endoscopic diagnosis.

Primary aortoenteric fistula is a rare but catastrophic cause of gastrointestinal bleeding. The diagnosis of primary aortoenteric fistula is difficult to make and is usually accompanied by a very high level of clinical suspicion. It should be considered in any elderly patient presenting with upper gastrointestinal bleeding in the context of a known abdominal aortic aneurysm. Prompt surgical intervention is necessary. We present the case of a 78-year-old man with a history of atherosclerotic abdominal aortic aneurysm which is presented with massive upper gastrointestinal bleeding due to a primary aortoduodenal fistula. Initial misdiagnosis led to a delay in treatment and the patient succumbed to the illness.

The epidemiology of primary biliary cirrhosis in southern Israel.

BACKGROUND: The epidemiology of primary biliary cirrhosis has changed significantly over the last decade, with a trend towards increasing prevalence in many places around the world. OBJECTIVES: To determine the overall prevalence of PBC in southern Israel and the specific rates for different immigrant groups between January 1993 and October 2004. METHODS: Multiple case-finding methods were used to identify all cases of PBC in the study region. Age-adjusted prevalence rates were compared among the different immigrant groups. RESULTS: A total of 47 cases of PBC were identified with an overall prevalence of 55 cases per million. All patients were women, and all except for a Bedouin Arab were Jewish. Foreign-born patients comprised 70% of our PBC cohort even though they represent only 45.4% of the regional population. This predominance of immigrants did not change when the rates were adjusted for age (P < 0.001). The prevalence rates were 40, 177, and 58 cases per million for those born in Israel, North Africa or Asia, and Eastern Europe, respectively. The age-specific prevalence rate for women older than 40 years varied from 135 cases per million among those born in Israel to 450 among immigrants from Eastern Europe and the former USSR to 700 cases per million among immigrants from North Africa and Asia. CONCLUSIONS: The prevalence of PBC in southern Israel is similar to that reported from some European countries. The rate is much higher among Jews than Arabs and among immigrants to Israel compared to native Israelis.

Microscopic colitis.

Microscopic colitis is an idiopathic chronic inflammatory bowel disease presenting with watery diarrhea. While colonoscopy and radiology findings are normal, the colon shows striking pathologic findings, including lymphocytic colitis and collagenous colitis. The clinical course is usually benign with sustained remission. Recent medical evidence shows that bismuth and budesonide are effective treatments.
