A female infant was born at the 38th week of pregnancy after an uncomplicated gestation of a 31-year-old mother. The birth weight was 2,550gr. and the APGAR score was 10. The child had a large solid tumor on the left-auricle. The mass was excised five days after the delivery. Microscopically, it was composed of spindle-shaped cells arranged in bundles, immature tumor cells, prominent vascular spaces with focal endothelial proliferation. The diagnosis was a congenital fibrosarcoma. Seven days after the 1st excision, radiotherapy followed by a wide local excision was performed. The patient was well and without recurrence 1 year after these treatment. A review of the medical literature indicates that wide local excision appears to be the treatment of choice for the congenital fibrosarcoma.
