Hi Maatson, you've been great so far at suggesting possible causes. I'm working on a list of possible causes to present to my internist. I was wondering what you think of pemphigus. It can have some strange effects on the oral cavity, including symptoms that mimic geographic tongue, as seen here from this photo found on the internet:

Pemphigus is also closely associated with beau's lines. I did indeed have beau's lines on my thumb and several fingers:

However, I believe Pemphigus is an auto-immune condition and so it should present with a positive ANA? My ANA test result was < 1:40 (negative). But I have been re-tested for ANA and should know the results by the end of this week.
Any thoughts about my beau's lines (which I forgot to mention up until now) and my ideas about pemphigus? Thanks again Maatson. I owe you one.
