[Leiomyosarcoma of the small intestine].

Leiomyosarcomas of the small bowel are quite rare. These tumors are mostly located in the jejunum distal of the duodeno-jejunal flexure. The non-metastasizing leiomyosarcomas have a good prognosis, according to the literature. The adequate surgical treatment is the resection of the small bowel. Chemotherapy is discussed if there is evidence of metastatic disease. For the diagnosis of leiomyosarcomas tumor markers have no significance. We report the case of a 79 years old patient with a leiomyosarcoma of the jejunum who was admitted as an emergency with an acute abdomen and underlying chronic anaemia. This case demonstrates the often unspecific symptoms and characteristics of leiomyosarcomas.
