Prenatal sonographic appearance of congenital fibrosarcoma

Abstract

Congenital fibrosarcoma is a rare soft tissue sarcoma. A 22‐year‐old woman in the 22nd week of her first pregnancy underwent sonographic examination, which revealed a soft tissue swelling of the fetus's left thigh. The pregnancy was terminated, and congenital fibrosarcoma was diagnosed by pathologic examination. To our knowledge, this is the first published report of the intrauterine sonographic observation of this tumor in a fetal extremity. © 1998 John Wiley & Sons, Inc.

Primary colonic congenital infantile fibrosarcoma presenting as meconium peritonitis

“…This is the only paraneoplastic condition associated with CIF noted in the literature [13]. There have been a few cases diagnosed prenatally by ultrasound as well-one a thigh lesion at 22 weeks gestation and another had a neck mass [13,14]. In addition, in one case a needle biopsy was obtained from a fetus, which helped to diagnose CIF in a 26-week fetus-this tumor was later found to be metastatic at autopsy [15].…”

Congenital infantile fibrosarcoma in a very low-birth-weight infant

“…With the widespread use of routine antenatal ultrasonography, reported cases with fibrosarcoma detected prenatally have increased (Table 1) [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Unlike postnatally diagnosed cases, prenatal CIFs are located in various sites, and only 3 of 14 cases occurred in limbs.…”
