A case of aplasia cutis after exposure to methimazole (Tapazole) in early pregnancy is described. Elevated maternal serum alpha-fetoprotein (MSAFP) and amniotic fluid alpha-fetoprotein (AFP) were found. Elevated MSAFP and amniotic fluid AFP in women exposed to methimazole may suggest this rare fetal condition.
