title: [Angiodysplasia of the duodenum with arteriovenous shunts, sub-serosal prevalence and interstitial elastosis; peritonitis and rupture of sub-serous dysplasic vessels and hemoperitoneum. Description of a case and review of the literature].
abstract: We present a case report of a 74 year old man, affected by angiodysplasia of the duodenum, which developed in peritonitis and hemoperitoneum. After undergoing two surgical interventions, it is 14 days since he died. First of all, the importance of this case is due to the extreme rarity of the angiodysplasia of the duodenum, specially when it becomes worse in peritonitis and hemoperitoneum, this case having been described only one time till now, then the localization mainly sub-serousal and lastly the presence of a component, characterized by an elastotic nature, disposed in islets and interstitial widespread also among the glands, which we have first described in literature.
