[Primary leiomyosarcoma of the small intestine in a child].
BACKGROUND
Leiomyosarcomas of the digestive tract are very rare in children. They must be differentiated from benign tumors (leiomyoma, schwannoma...) and from other malignant tumors, sometimes with the aid of immuno-histochemical study.


METHODS
A five-year old girl suffered from an abdominal mass associated with fever and alteration of the general condition. An ileal tumor, 8 cm in diameter, was resected. Histological and immunohistochemical studies (anti-vimentin antibodies, anti-actin antibodies and PS100) confirmed the diagnosis of leiomyosarcoma. Uncomplete adjuvant chemotherapy failed to prevent relapse of the tumor.


CONCLUSIONS
This case confirms the bad prognosis of such a tumor.
