With reference to a new case of pancreatic cystadenoma, the authors review the literature on the subject. These tumors are a relatively uncommon form of cystic lesion of the pancreas. They find the origin from pancreatic acinar cells or from ductal epithelium. Histologically, there are two different forms: benign, serous, microcystic adenoma and potentially malignant, mucinous, macrocystic adenoma. The type of the tumor is demonstrated by ultrasonography and computed tomography. but these examinations could not make a difference between benign and malignant form. Treatment of choice is complete tumor resection. Internal or external drainage of these cysts should not be done.
The authors report two cases of peritoneal tuberculosis observed in Belgium: a 28-year-old black man, immigrant from Ghana and a 24-year-old caucasian woman. In both patients, tuberculosis was associated with another infection. The first patient had a retroperitoneal amoebic cyst and in the second patient Chlamydia trachomatis was found with Koch bacillus in the ascitic fluid. Both patients were successfully treated with appropriate antibiotics. Following the review of recent literature, it appears that the incidence of extrapulmonary tuberculosis is increasing in the industrialized part of the world, peritoneal tuberculosis now representing 0.5% of all cases of tuberculosis. Mortality approaches 7%. The diagnosis is difficult and should be evoked more often in order to be confirmed by appropriate means, such as ascitic fluid adenosine desaminase, bacteriology and peritoneoscopy.
Rupture of an infrarenal aortic aneurysm occurring in a 94- year old man is reported. Eight months after surgery the patient is still alive. Indications of elective surgery for asymptomatic abdominal aneurysm in the elderly are discussed.
