CONGENITAL FIBROSARCOMA MASQUERADING AS LYMPHATIC MALFORMATION - REPORT OF 2 CASES

Two infants presented with a congenital cervicothoracic mass; both wer e initially diagnosed as having lymphatic malformation. A biopsy speci men for one child and excision for the other showed that both lesions were congenital fibrosarcomas. Postoperative chemotherapy was administ ered to both children. One died within 6 months of incisional biopsy f rom widespread metastatic disease; the other is still being treated. C ongenital fibrosarcoma can be confused in its clinical presentation, r adiographic findings, and histopathology with lymphatic malformation ( cystic hygroma). Copyright (C) 1995 by W.B.
