[A case of malignant intestinal lymphoma following a successful kidney transplant]

A rare case (the first one described in Bulgaria) of malignant intestinal lymphoma, developing in a 50-year-old patient 9 years after transplantation of a normally functioning corpse kidney, is reported. Basic predisposing factor for the lymphoma was the long-term maintenance immunosuppressive therapy with azathioprine and corticosteroids. Apart from this finding, a dissecting aneurysm of the abdominal aorta with partially obliterating thrombus was found. The patient died in a state of severe toxemia of suppurative peritonitis after perforation of the intestines heavily affected by the lymphoma.
