Congenital fibrosarcoma. Report of three cases.

Congenital/Infantile Fibrosarcomas are relatively rare soft tissue tumours. Only 238 cases have been reported till 1986 in the world literature of which 60 were truly congenital. A distinction must be made between them and their adult counterparts because of differences in their clinical behaviour. The authors report three cases and highlight their biological behaviour. Despite having an aggressive histological appearance they have a relatively benign course.
