Adenocarcinoma of the small bowel revealing celiac disease in an adult: case report.

Cancer of the small bowel is a rare malignancy. With an incidence of less than one per 100 000 people, it makes up only 5% of all gastrointestinal tract cancers. Celiac disease is a relatively common pathology and is often associated with the development of small bowel lymphoma. However, it is also a known risk factor for small bowel adenocarcinoma. The authors are reporting a case of a patient with recurrent bowel obstruction found to have a small bowel adenocarcinoma and an underlying celiac disease.

Overlap syndrome of primary biliary cholangitis and primary sclerosing cholangitis: two case reports.

BACKGROUND: Overlap syndrome between primary biliary cholangitis and primary sclerosing cholangitis is an extremely rare condition that has been reported in only few published cases so far in the literature. We highlight here the rarity of this condition and indicate the importance of its recognition. CASE PRESENTATION: We report two cases showing the manifestations of both primary biliary cholangitis and primary sclerosing cholangitis in two Tunisian female patients aged 74 and 42 years, respectively. The first case is a woman who was initially diagnosed with decompensated cirrhosis. Magnetic resonance cholangiopancreatography showed multiple strictures of the common bile duct, and histological findings led to the diagnosis of primary biliary cholangitis/primary sclerosing cholangitis. She was successfully treated with ursodeoxycholic acid. The second case is a middle-aged woman, suffering from primary biliary cholangitis and who was treated with ursodeoxycholic acid. At her 12 month follow-up appointment, she presented with a partial clinical and biochemical response. Tests showed normal thyroid function, liver autoimmune tests for autoimmune hepatitis were negative, and celiac disease markers were also negative. The diagnosis of overlap syndrome of primary biliary cholangitis/primary sclerosing cholangitis was finally made on the results of magnetic resonance cholangiopancreatography that showed multiple strictures of the common as well as intrahepatic bile ducts. The patient was put on ursodeoxycholic acid at a higher dose. CONCLUSIONS: Our cases raise awareness for this rare condition and indicate the importance of recognizing a possible overlap syndrome, especially in patients with primary biliary cholangitis, to optimize treatment. We suggest considering the overlap syndrome of primary biliary cholangitis/primary sclerosing cholangitis when a patient presents with the diagnostic criteria of both diseases.

Gastrojejunocolic fistula: a rare complication of peptic ulcer surgery.

Gastrojejunocolic fistula (GJF) is a very rare complication of peptic ulcer surgery. Patients with this condition often present with diarrhea, fecal vomiting as well as weight loss. Here, we report a case of 62-year-old male with a GJF complicating upper gastrointestinal surgery.

Peritoneal mesothelioma associated with bladder cancer and occupational exposure to asbestos: A case report.

Mesothelioma is a rare tumor usually located on the pleura. In this typical location, it is closely linked to asbestos exposure. However, in other locations such as in peritoneal mesothelioma, the association to asbestos remains unusual.

Hepatocellular carcinoma arising from hepatic adenoma in a young woman.

Hepatocellular carcinoma (HCC) arising from hepatic adenoma is an infrequent situation. Only a few cases were reported in the literature. We present a rare case of hepatocellular carcinoma arising from HA in a young woman with no medication history of oral contraceptives. Surgical resection is the only available treatment.

Rheumatologic manifestations during chronic viral hepatitis C.

INTRODUCTION: Chronic hepatitis C (CHC) is assimilated to a systemic disease because of its multiple extrahepatic manifestations particularly rheumatological. AIM: To determine the prevalence and the characteristics of rheumatological manifestations (RM) associated with CHC. METHODS: a retrospective study including all patients suffering from CHC followed over a period of 11 years (2002 - 2012) at the department of gastroenterology B at La Rabta hospital. Were excluded all patients co-infected by hepatitis B virus or by human immunodefficiency virus and those having decompensated cirrhosis. Different RM were collected and analyzed according to the epidemiological, clinico-biological, immunological, virological and histological data of the CHC. RESULTS: two hundred and four patients affected by CHC were included, meanly aged by 52 years [22- 66 years]. The sex-ratio was 0,46. RM were noted in 76 patients (37,25%) dominated by inflammatory polyarthralgia of big joints (88,15%). Non erosive arthritis was observed in a woman, myalgia was noted in 11 cases (14,47%) among them, 2 appeared under antiviral treatment. Dryness syndrome was observed in 17 cases (22,36%). RM were associated to other extrahepatic manifestations of CHC in 69,7% of cases, notably to mixed cryoglobulinemia (MC) (60%) and to non specific antinuclear antibodies (21,6%). A partial to total amelioration of RM was noted in most patients under antiviral treatment often associated to symptomatic measures. In univariate analysis, only female sex and presence of MC were significantly correlated to the presence of RM. CONCLUSION: RM occur frequently inCHC and are dominated by arthralgia, myalgia and dryness syndrome. Authentic arthritis are uncommon and constitute a diagnostic problem particularly when they inaugurate the disease. MC is the immunological factor the most associated with RM. MR treatment remains mainly antiviral.
