Multifocal leiomyosarcoma of the small intestine in childhood.

We recently observed a 4-year-old Chinese boy with multifocal leiomyosarcoma of the small intestine with evidence of dissemination. Complete surgical excision was not possible and the response to postoperative chemotherapy was poor. The patient died 3 months after diagnosis. The prognosis for disseminated intestinal leiomyosarcoma in childhood appears to be poor.
