Abstract
We have interestedly read the article written by Thalia Wong BS in July 2015, which is about Pediatric Blood Cancer, including clinical findings and results of infants <1 year of age with Ewing sarcoma. We report a case with congenital Ewing's sarcoma that easily interfered with rabdomyosarcoma in a pregnant woman. A 32-year-old multigravida with a big neck mass at 35 weeks was referred to our clinic. The final diagnosis of extraskeletal Ewing's sarcoma was made. Hepatic metastasis was detected and treatment by chemotherapy was initiated. Ewing's sarcoma is usually noted among adolescents or young adults and more rarely than among newborns. This case is important because of its rarity.
