Tongue Image Challenge

It has been awhile since we have had an image challenge for you to solve.  This is a fairly common condition that we see.  What do you think the diagnosis is?

1.  Geographic tongue

2.  Oral candidiasis

3.  Lichen planus

4.  Oral hairy leukoplakia

5.  Pemphigus vulgaris

Make your diagnosis in the comments section and check back tomorrow for the answer.
