Case report. - A five-year old girl suf fered from an abdominal mass associated with fever and alteration of t he general condition. An ileal turner, 8 cm in diameter was resected. Histological and immunohistochemical studies (anti-vimentin antibodies , anti-actin antibodies and PS100) confirmed the diagnosis of leiomyos arcoma. Uncomplete adjuvant chemotherapy failed to prevent relapse of the turner. Conclusion. - This case confirms the bad prognosis of such a tumor.
