An unusual case of bilateral kidney tumors with two histologically different tumors, one right-sided oncocytoma and one left-sided renal cell carcinoma is described. The morphological features of the two tumors are briefly delineated. The diagnostic dilemma between an oncocytoma and a renal cell carcinoma is discussed.
In a prospective randomized study, 25 recipients of primary cadaveric renal grafts with immediate onset of function were studied. Thirteen patients were submitted to a "base line" angiography of the graft on days 5 to 11 after transplantation, while 12 patients served as controls. HLA compatibility, pretransplant blood transfusions, and recipient age differed only slightly between the two groups. Six of 13 patients in the angiographed group showed clinical evidence of acute rejection within the first 14 days after grafting; of these rejections, two were diagnosed prior to angiography. In the control group, 9 of 12 patients rejected their grafts within the first 2 weeks. Thus, there was no indication that renal angiography in the early post-transplant period precipitated acute rejection crises, as has earlier been suggested.
A case of hemorrhage in a pancreatic pseudocyst presenting as massive gastrointestinal bleeding is reported. In the event of an unexplained GI-bleeding in an alcoholic this diagnosis should be considered. Selective angiography during bleeding may lead to correct diagnosis.
