Role of elevated alpha-fetoprotein in prenatal diagnosis of junctional epidermolysis bullosa and pyloric atresia.
A case of junctional epidermolysis bullosa, Herlitz variant, and pyloric atresia in a 33 weeks' gestation male infant is reported. The second trimester amniotic fluid exhibited elevated concentrations of alpha-fetoprotein and presence of acetylcholinesterase; however, the fetus appeared anatomically normal by multiple high-resolution ultrasound examinations. This case, as well as others previously reported, shows that serious fetal skin disease should be considered as part of the differential diagnosis whenever persistent elevation of alpha-fetoprotein and presence of acetylcholinesterase are found in the amniotic fluid of a fetus that appears anatomically normal by ultrasound. Prenatal diagnosis may be established by fetal skin biopsy and extensive prenatal counseling should be offered to families on the basis of the prognosis and severity of this disease.
