Aplasia cutis congenita in a setting of fetus papyraceus associated with small fetal abdominal circumference and high alpha-fetoprotein and amniotic acetylcholinesterase.

Fetus papyraceus is the fetal death of one or more fetuses in a multiparous pregnancy. The surviving infants can experience extensive aplasia cutis in an H-shaped distribution over the flanks and abdomen as a consequence of the loss of their fetal sibling. We report the case of a monochorionic, diamniotic pregnancy complicated by a single fetal death at 13 weeks of gestational age.
