title: [Ischemic stenosis of the ileum with reactive parietal and lymph-nodal angioendotheliomatous hyperplasia].
abstract: Ischemic stenosis of ileum with reactive parietal and lymph node angioendotheliomatous hyperplasia. The case subject of this study represents a form of segmentary chronic ischemic enteritis with intramural haematoma, intestinal stenosis and neighbouring mesenteric venous thrombosis. In the histopathologic picture it is of great interest a peculiar lesion of the intestinal wall which has been interpreted like reactive nodular angioendotheliomatous hyperplasia, associated to diffuse parietal granulation tissue formation and marked transmural neoangiogenesis. This lesion also interests a small locoregional mesenteric lymph node, where it appears to be included in a morphological picture of nodal angiomatosis (also known as vascular transformation of lymph node sinus). The last pathological entity has been thought to take rise from a local perinodal venous obstruction. This aetiopathogenetic interpretation has been also referred to the lesion of the intestinal wall which for the Author's knowledge is not accompanied by similar examples in the literature. The patient is a 28 years old man who after a six years follow up presents perfect health.
