[Surgery without boundaries].

Surgery at the turn of the century and at the millennium is characterised by an extremely rapid development. There are no boundaries anymore among the different branches of medicine, in different anatomical regions of the human body, between the living human and the artificial tissues, between the reality and the virtual reality. Nanotechnology and robotics offer new possibilities for minimally invasive procedures.

Giant adrenal myelolipoma.

Authors present a case of giant adrenal myelolipoma, where the tumor was hormonally inactive but caused abdominal and flank pain. The huge tumor, a 20x18x10 cm mass, was surgically removed. The ipsilateral kidney was preserved.
