Abstract

Fibrosarcoma in newborns and infants, designated as congenital, infantile, or juvenile fibrosarcoma is an uncommon soft tissue neoplasm occurring most frequently during the first year of life. Infantile fibrosarcoma is associated with favorable clinical behavior that is markedly different from that of adult fibrosarcoma., We report a case of infantile fibrosarcoma occured in a 3-year-old boy presenting as a palpable mass in the left lower extremity since 3 months of life. Histologic findings of the tumor are similar to those of f ibrosarcomas in adult.
