Infantile fibrosarcoma - an important differential diagnosis of congenital vascular tumors.

We present the case of a female newborn with life-threatening bleeding of a ruptured infantile fibrosarcoma (IFS) and consecutive multiorgan dysfunction syndrome shortly after birth. After stabilization, the tumor could be treated without amputation due to surgery, laser therapy, and chemotherapy. The patient is free of tumor and doing functionally well after 4 years of follow-up.
