[Pancreatic cystadenocarcinoma revealed by an acute pancreatitis and exploratory surgery. A rare case report].

Cystadenocarcinoma of the pancreas is a rare malignant tumor. It may appear as a typical pseudocyst on ultrasonography or CT scan. It is exceptionally revealed by an acute pancreatitis.

[Primary pneumococcal peritonitis in children].

Since the advent of antibiotics primary pneumococcal peritonitis rarely occurs except in association with immunodepression and a detectable port of entry involving the lung, upper airways, or female genital tract. This clinical picture was observed in an 8-year-old girl who underwent surgery after an initial diagnosis of appendicitis-related peritonitis. Surgical exploration revealed a macroscopically and microscopically normal appendix and purulent peritoneal effusion.

[Rupture of the bile ducts in closed abdominal injuries].

A further case of rupture of the biliary pathways from a closed injury to the abdomen is reported. The exceptional nature of the lesion was further evidenced by the delay in diagnosis of this rupture: on the 45th day after the injury. Reports in the literature describe the most frequent characteristics of such lesions: affecting young adults they are usually the result of road accidents, they are diagnosed at a late stage due to lack of information from complementary examinations, and they raise problems related to the choice of therapy.
