[Leiomyosarcoma of the Small Intestine in the Young Adult: Unusual Diagnostic Approach]

The authors report the case of a 40-year-old woman with fever and diarrhoea in whom a tumour of the small intestine was discovered by computerized tomography (CT), the barium meal being not contributory. Transcutaneous fine needle aspiration biopsies under CT guiding revealed a grade II leiomyosarcoma. Twenty months after radical resection, the patient is alive and asymptomatic. The authors review the literature about the histological grading and the immunocytochemical characteristics of leiomyosarcoma, its treatment and prognosis.
