A Case of Leiomysarcoma

This paper presents a case of leiomyosarcoma which developed in the retroperitoneal cavity. On admission, this 4 months old male infant disclosed a adult fist sized mass with abdominal distention and scattered nevus lesions on the left sided abdomen on physical examination. IVU examination revealed urinary collecting system to be unremarkable, but right kidney and ureter were displaced to upward and posterior respectively. On 6th hospital day, we performed explorative laparotomy and removed the tumor mass measured 15X11cm in size. Histologic finding revealed leiomyosarcoma. Review of literature was also made breifly.
