Congenital infantile fibrosarcoma of the thigh in a newborn.

Congenital/infantile fibrosarcoma occurs frequently in the first year of life and differs from fibrosarcoma in adulthood. The clinical course of congenital/infantile fibrosarcoma is more favorable and metastatic spread is rare. While adult fibrosarcomas are common in the thigh, congenital/infantile fibrosarcomas affect chiefly the distal portions of the extremities. Standard treatment is primarily wide surgical excision. Chemotherapy may be given as neoadjuvant or adjuvant treatment in order to avoid the morbidity associated with wide excision. In this case report we present our experience of a newborn affected by congenital/infantile fibrosarcoma of the left thigh.
