### input:
I have had strep throat too many times to count but about 5 years ago I had the worst strep infection yet (throat so swollen that I was having difficulty breathing and took 3 types of antibiotics to get rid of...) after that infection I was referred to a specialist to follow the infections to see if my tonsils should be removed (b/c of repetitive infections) however they just said if I had one more infection they would remove but since then I have not had any.  It is so weird b/c since I was young I had 2-5 strep ouinfections a year but since that last crazy infection - NONE!  Also about a month or so after the last infection I noticed somewhat of a whitish/grey spot (about a 1/2 inch in size) on my right tonsil, not concerned I just thought it was maybe scar tissue or something.  Recently, I noticed the whitish area has turned a purplish/black color.  Any thoughts?  I have a history of smoking - should I be worried or no.   There is no pain surrounding the area, just an abnormal color.

### output:

Hi I did review your concerns would advise you to consult a ENT doctor and get the lesion evaluated. The purple lesion which is localized can be anything from a blood vessel problem to that of melanocytes. Common lesions that can present like this include smokers Melanesia (since you have smoking habit) and also hematoma(blood vessel proliferation) or nevus. The doctor will examine it clinically and if required will take a tiny biopsy to rule out anything worrisome. I would meanwhile recommend you to quite smoking as good as you can. I hope this yellowish you all the best. Thank you for using Chat Doctor.
