Hello doctor, I am a 40-year-old female, not taking any medications. I have a flat, round to oval new lip patch. I noticed this about two to three months ago, no other symptoms other than the appearance of it and it is about 8 mm. It is light purple or brown in color. Please advice.
Hello. I have gone through your case. In my opinion, there is two to three differential diagnosis of your lesion. 1. Lichen planus - This could result due to many reasons or sun exposure. Treatment is sunprotection by frequent application of any sunblock. Try to apply sunblock at least 20 minutes before going outside. And use it two to three times a day. 2. Fixed drug eruption (FDE) - Many drugs can cause it. Most common causes are NSAIDS or antibiotics like penicillin. But you have told that you do not take any medicines. Re-evaluate yourself if you have taken any few weeks ago. Treatment is never to retake it and apply Hydrocortisone cream two times a day.
