Dark patch of skin on shin
by LuvMyBug, Jan 03, 2006 12:00AM
Hello,
Just prior to being dx with hypothyroidism I noticed a dark patch of skin on my shin. It has been about a year now and it has grown in size (approx. the size of a business card). It looks like a bruise, is shiny and warm to the touch. I thought it was pretibial myexedema, but my endo say PTM is usually raised and bumpy. He is referring me to a dermatologist.
Any ideas what this could be? It doesn't hurt, but is unsightly.
Thanks!

Does not sound like classic myxedema -- and usually myxedema is caused by Graves, not hypothyroidism (but it's possible). The dermatologist will likely do a biopsy -- hopefully that will determine the cause.
It may not be PCOS but it's good to rule out.
I am hypothyroid/PCOS and there seems to be some link between the two diseases.
I hope you find your answer soon.
