I don't think it's a birthmark because I am pretty sure it has not always been there. But I have noticed it has been there for months now. It is about the size of a dime, and only seems to be a weirdly shaped spot with darker skin then the rest of my thigh. It does not burn or itch or feel any different. It kind of looks like a bruise. The area around it is a little red as I tried to shave the area quickly to get a clearer picture.
(see attached pic, others here [though they all look the same]: http://tinypic.com/r/w9xppu/5 http://tinypic.com/r/mwskyr/5 http://tinypic.com/r/mwskyr/5 http://tinypic.com/r/25jyqop/5)
Is the spot anything I should be worried about?
This kind of spot can be due to dermatitis skin or granuloma annulare. Granuloma annulare is a chronic disease consisting of a rash with reddish bumps arranged in a circle or ring. Usually it is asymptomatic but due to cosmetic disfigurement topical or oral steroids may be needed. Please discuss this with your dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
