[Primary angiosarcoma of the spleen].

Primary spleen angiosarcoma is a malignant neoplasia based on vascular tissue and it is a rare tumor (65 cases published). The clinical aspects are obscure and the specific diagnosis is made by laparotomy. The prognosis is very poor in any case and survival isn't more than two years, whenever the spleen undergoes spontaneous rupture in which case the survival should be less than six months. The splenectomy before rupture could increase survival. Patients with or without metastatic disease may be treated by chemotherapy but with poor results. Radiotherapy is used for relief the pain produced for bone metastasis.

[The extraintestinal manifestations of Crohn's disease: our experience].

During a period of sixteen years we have treated 120 patients with Crohn's disease, 41 of them with extraintestinal lesions besides of it's main intestinal pathology. These patients represented the 34.1% of all attended in this service. We describe the clinical and epidemiological aspects and the incidence of extraintestinal manifestations of the disease. Joint manifestations were prominent (90.2%), followed by cutaneous-mucosal lesions (47.8%) and cholelithiasis (24.3%). Urinary symptoms secondary to fistula or invasion from the adjoining inflammatory process came in fourth place. Other rare localizations are described. The literature is reviewed.

[Acute abdomen caused by rupture of aneurysms of the pancreatico-duodenal arteries. Apropos of a clinical case].

A case of acute abdominal hemorrhage caused by the rupture of several aneurysms of the pancreatoduodenal artery is presented. We discuss the difficulties of the diagnosis and point out the importance of the arteriographic study, as always in vascular lesions. We emphasize the difficulties of the treatment; most cases require surgical approach, going from suture of the aneurysm to cephalic duodenopancreatectomy.

[Biliary lithiasis].

We have reviewed our experience with 2,430 cases of lithiasis of the biliary tract, 500 of them located in the common bile duct and 104 corresponding to residual lithiasis. We have made a general reflexion on the problems aroused by this very common al condition, which has an imprevisible, some times severe, outcome. The recent acquisition of new conservative methods, as disolvents and lithotrix, and the diagnostic and therapeutic role of endoscopy have revolutionated the state of the art and have introduced controversial points still unsolved. As it is common in clinical practice, biliary lithiasis should be approached in a multidisciplinary fashion, employing the most convenient diagnostic procedure for the clinical situation of the patient; a priori no accredited procedure should be disregarded.
