[|Human|] I got a pinkish spot on lower lip ,but when i stretch my lower lip, it appears white. I got no pain or not but I am concerned about it. I am from the Caribbean and I spend allot of time in the sun all my life to present. Went to a doctor before and he said it could or is sun exposure and I started to use my saliva to keep it moist and it disappeared for a little while.
[|AI|]  HelloWelcome to ChatDoctorI would like to tell you that there are few possibilities & to rule out it's important to know the sign & symptom like:- -if it occurs at corner of mouth & causes itching then it can be angular cheilitis-it can be Angola if it is painless & disappears on stretching, you can get blanching test done to rule out. For more detailed diagnosis need to go for biopsy. Take Disregards Chat Doctor.
