    ABSTRACT: Hemosuccus pancreaticus, particularly that caused by a primary aneurysm, is rarely encountered. Thus, its clinical characteristics are not well known. We report the case of a 53-year old man, who presented with hemosuccus pancreaticus caused by the rupture of an atherosclerotic aneurysm of the splenic artery and underwent distal pancreatectomy with splenectomy. Only 16 cases of hemosuccus pancreaticus due to primary aneurysm have previously been reported in the English-language literature between 1970 and 2003. The relevant literature was also reviewed. The review of the literature showed that because diagnosis is difficult to establish due to intermittent hemorrhage, a long time was often taken before definitive treatment was instituted. Treatment based on a definitive or suspected diagnosis reached a satisfactory result; however, the condition can cause a life-threatening situation. When upper gastrointestinal bleeding from an obscure source is encountered, hemosuccus pancreaticus should be considered. We suggest that when an aneurysm of peripancreatic vessels is present, adequate treatment for the aneurysm should be immediately undertaken, even though the site of the bleeding has not been confirmed.

    ABSTRACT: The case of a 71-year-old man with aneurysms of bilateral profunda femoris arteries associated with so-called “arteriomegaly” is presented. Both aneurysms were resected and only the left lateral femoral circumflex artery was reconstructed. Atherosclerotic aneurysms of the profunda femoris artery are rarely encountered, but once diagnosed, surgical repair is generally recommended to avoid complications. However, there are no cases presenting with complications of diameters less than 2 cm; therefore, we suggest that a profunda femoris aneurysm over 2 cm in diameter is an indication for surgical treatment. If the superficial femoral artery is patent, ligation without reconstruction of the profunda femoris artery does not cause severe leg ischemia; so that in such cases, reconstruction of the profunda femoris artery is not necessary.

    ABSTRACT: We report a case of primary choriocarcinoma of the jejunum in a 45-year-old man, which was finally diagnosed by immunohistochemical analysis of a surgically resected specimen. Despite combined systemic chemotherapy, the patient died of progressive liver metastases 5 months after surgery. The serum human chorionic gonadotropin (HCG) level increased dramatically as the liver tumor progressed. According to our review of the 13 cases of primary or secondary choriocarcinoma of the small intestine reported in the English-language literature up until 2001, the characteristic symptoms are massive gastrointestinal bleeding and elevation of the serum HCG. Early diagnosis and prompt initiation of chemotherapy provide the only chance of improving the extremely poor prognosis associated with this rare neoplasm.
