I've never seen them but when my daughter (Caucasian) was born she had a red mark on her head that they said is very common for Caucasians. My husband asked what other races would have and they mentioned the large blue marks for Asians....and I can't remember what other's there are.

Kind of interesting. The family likely is just so used to it as it's the norm for them and their culture they didn't realize to give a heads up!
