[Agenesis of the gallbladder].

The agenesis of the gall bladder is a rare congenital abnormality that usually is diagnosed as cholecystolithiasis. Therefore it is an intraoperative discovery. In this work two new cases are added to casuistry; both them have received laparotomic treatment. As those cases were symptomatic patients, the most common clinical manifestations are described. We insist in tactics to discard ectopic locations and the different options for the intraoperative and postoperative study; this last situation seems to be the most used behavior on patients approached laparoscopically.

[Liver leiomyosarcoma].

Hepatic tumors are infrequent. Sarcomas represent less than 2% of them, and Leiomyosarcoma (LMS) is a certain rarity. The frequency grows from primitive tumors to metastatic tumors and in the last years, in relation with different immunodeficiencies. A case of a patient diagnosed in the postoperative and assisted in two relapses until her death, is reported. The possible aetiologies are analyzed in the hepatic gland that does not have muscle of its own, as well as in diagnostic and therapeutic modalities, insisting in the lack of rules, because of the low number of publications. Morphologic variations between the primitive tumor and its relapses are also shown.
