Late-onset intestinal perforation in the setting of posttransplantation microangiopathy: a case report.

Intestinal perforation in the setting of posttransplantation microangiopathy (TMA) is a very rare event and might be considered a terminal event of intestinal microangiopathy (i-TMA), a rather rarely recognized posttransplantation complication, as it overlaps with the more common intestinal graft-versus-host disease (GVHD). Cases of i-TMA described in literature occurred within with first 100 days posttransplantation or shortly thereafter. In this report, we describe a case of late-onset intestinal perforation that occurred in the setting of systemic microangiopathy more than a year after allogeneic transplantation. In our case, the patient poorly responded to treatment secondary to refractory mircoangiopathy. Published by Elsevier Inc.
