There's a weird syndrome called PUPPP that affects some women in late pregnancy. It is thought to be caused by the overload of hormones, and the only thing that cures it is childbirth. It isn't related to ichthyosis, though. http://www.emedicine.com/derm/topic351.htm
Ichthyosis-en-Confetti Type 2
Husband, Nathan - 10, Elliot - 7, Oliver - 4, all affected.
I also have an unaffected daughter, age 8.
