title: Unusual prenatal sonographic findings without an elevated maternal serum alpha-fetoprotein level in a fetus with epidermolysis bullosa.
abstract: A 31-year-old pregnant woman was referred to us at 34.6 weeks' menstrual age for sonographic evaluation of a fetal left lower limb abnormality. Sonographic findings revealed shortening of the left tibia and dorsal hyperflexion of the left foot. There was no family history of genetic disease, and the maternal serum alpha-fetoprotein concentration was normal. A male infant was born with extensive skin peeling, mainly on his left leg, associated with muscular dystrophy. Epidermolysis bullosa was confirmed on a skin biopsy; the neonate died 53 days after birth as a result of severe sepsis. Although cutaneous epidermolysis bullosa is difficult to diagnose prenatally, shortening and deformity of extremities may provide a clue to the diagnosis, even when the maternal alpha-fetoprotein concentration is normal. © 2015 Wiley Periodicals, Inc.
