[Leiomyosarcoma of the jejunum associated with severe enterorrhagia. Clinical case].

The paper describes a cases of jejunal leiomyosarcoma associated with severe enterorrhagia. The rarity of this lesion and its difficult diagnosis are underlined. Having discussed the different anatomo-pathological aspects, the most appropriate diagnostic methods for a early diagnosis are examined. Moreover, the utility of carrying out a regular clinical and diagnostic follow-up of patients who have undergone surgery is stressed so that possible relapses or metastases, which are fatal in the majority of subjects affected by this form of neoplasia, can be treated as quickly as possible.
