[Histopathologic aspects of hyperacute graft rejection in human cardiac transplantation. A case report].
The first case of a hyperacute rejection of a human cardiac allograft in Brazil is reported. The histopathological aspects of hyperacute cardiac rejection in its earlier moments are described when degenerative and necrotic features of the cardiac fibers are not totally developed. The authors believe that neutrophilic exudation and lesion of the vessel wall are good signs for a correct diagnosis of hyperacute rejection. Furthermore, they observed that the process is diffuse enough to justify the indication of endomyocardial biopsy when there are reasons to suspect this diagnosis. Presence of IgM and complement (C3) are also useful.
