title: Leiomyosarcoma arising from the inferior mesenteric vein.
abstract: Leyomiosarcomas arising from the portal/mesenteric venous system are very rare tumours, and only a few cases have been reported in the global literature. As the other leyomiosarcomas of vascular origin, they are associated with a poor prognosis. The present report describes the case of a 66-year-old woman with a leyomiosarcoma of the inferior mesenteric vein, unexpectedly found during a CT scan performed for another indication. A brief review of the literature is also given. The patient underwent radical surgical excision and enjoys a good health, without radiological signs of recurrence, 24 months after surgery. In this case, an early incidental diagnosis determined an early treatment and, probably, a favourable prognosis. This is the second case of leyomiosarcoma of the inferior mesenteric vein reported in the literature.
