Infantile fibrosarcoma: report of cases

Infantile "fibrosarcoma" occurred in a newborn male infant and in a 2-month-old female infant. In both cases, the tumors grew rapidly and showed the histological features of malignancy. However, they were treated successfully with simple resections. Review of the literature shows that infantile fibrosarcoma has a relatively favorable prognosis. Simple local excision is the initial treatment of choice for lesions occurring in infants and children less than 5 years old.
