Cardiac transplantation is most effective method for treatment of patients with end-stage heart disease. We present the experience of our institution with 1,564 biopsies and 11 autopsies of 105 orthotopic heart transplants. This report describes the morphological features and the grading systems of acute rejection. Also, we present the morphological characteristics of other complications of heart transplants such as chronic rejection, "Quilty" effect, interstitial fibrosis, heart hypertrophy, previous biopsy sites, calcification, cytomegalovirus infections, toxoplasmosis, and the appearance of malignancies, mainly, lymphomas. Actuarial survival of patients is 91% and 88% at 1 and 5 years' posttransplant, respectively.

Brunner's glands adenomas represent the 10% of the benign duodenal tumours. The most frequent site is the first portion of the duodenum, and they are extremely rare distally to the ampulla of Vater. We present two cases, one of them associated with an adenocarcinoma of the ampulla. This association has not been previously described in the literature. The transformation of an adenoma into an adenocarcinoma has neither been reported. We believe that the term hyperplasia should be used only for diffuse proliferations.
