[Updating case studies of primary tumors of the mesentery: angiofibroma involving the superior mesenteric artery]. / Aggiornamento casistico sui tumori primitivi dei meso: angiofibroma coinvolgente l'arteria mesenterica superiore.

The authors describe a rare case of jejunal mesenteric angiofibroma involving the superior mesenteric artery, referred to them as a clinical finding of an abdominal mass with associated disorders of alimentary transit. A review of the literature reveals the controversies existing to date on the subject of mesenteric neoplasms. In addition to their rare incidence, also confirmed by our personal experience in two surgical centres, intraligamentous abdominal tumours arouse interest owing to the diagnostic difficulties which as a rule hinder a precise pre-operative orientation and to surgical problems of a tactical nature related to the frequent involvement of adjacent anatomical structures.
