Our pathologist spoke to the ordering physician and told him he
thought it was an early form of a crab louse.  The physician did not
seem surprised and said he would treat her with the appropriate
shampoo.  I'm sorry I didn't have a picture to post, but that's where
the case has ended up.  

Thank you everyone for your postings.  I appreciate it.
