An infantile leiomyosarcoma that metastasized from the small intestine to the adrenal gland.

In the literature, there is no reported pediatric leiomyosarcoma case that has metastasized from the small intestine to the adrenal gland. A 10-year-old boy who had anemia and weight loss over 2 years presented with abdominal pain that began 1 week previously. Radiologic examination revealed bilateral adrenal tumors. At the time of surgery, the terminal ileum was resected and a tru-cut biopsy was done from the right adrenal mass. The pathology report was leiomyosarcoma for both of the resection and tru-cut specimens. We present an intestinal leiomyosarcoma that metastasized from the small intestine to both adrenal glands with clinical, morphologic, and immunohistochemical studies with a literature review.
