Fibromyxoid sarcoma in a 4-year-old boy: case report and review of the literature

The authors report on the case of a low-grade fibromyxoid sarcoma (LGFMS) with giant rosettes in a 4-year-old boy. The tumor arose in the paravertebral region and had infiltrated the vertebral canal between L2 and S1. A review of the literature indicates that this is one of the youngest patients diagnosed with a tumor of this type, and spinal involvement had never been reported with LGFMS.
