From Sally Stokes
I read with interest Helen Pilcher’s report on different “identical” twins (31 August, p 44), and was surprised that she did not allude to the possibility that the twin born with two vaginas, two colons and a split spinal cord might have absorbed a third fetus.
Some form of fetal resorption is, according to Charles Boklage of East Carolina University in Greenville, North Carolina, not uncommon, and may occur in one in eight multifetus pregnancies.
