Please help me regarding this issue, I will be very thankful to you.
Freckles and irregularly shaped brownish areas (melanotic macules) are common around the lips and may last for many years. These marks are not cause for concern. Multiple, small, scattered brownish black spots may be a sign of a hereditary disease called Peutz-Jeghers syndrome, in which polyps form in the stomach and intestines.
Sun damage may make the lips, especially the lower lip, hard and dry. Red speckles or a white filmy look signal damage that increases the chance of subsequent cancer. This type of damage can be reduced by covering the lips with a lip balm containing sunscreen or by shielding the face from the sun's harmful rays with a wide-brimmed hat.
The tongue's villi may become discolored if a person smokes or chews tobacco, eats certain foods, or has colored bacteria growing on the tongue.
The top of the tongue may look black if a person takes bismuth preparations for an upset stomach. Brushing the tongue with a toothbrush or scraping it with a tongue scraper can remove such discoloration.
Iron deficiency anemia may make the tongue look pale and smooth. Pernicious anemia, which is caused by a deficiency of vitamin B12, may also make the tongue look pale and smooth. The first sign of scarlet fever may be a change from the tongue's normal color to a strawberry, and then raspberry, color. A strawberry-red tongue in a young child may also be a sign of Kawasaki disease. A smooth red tongue and painful mouth may indicate pellagra, a type of malnutrition caused by a deficiency of niacin (vitamin B3) in the diet. A red tongue may also be inflamed (glossitis)—the tongue is red, painful, and swollen.
Whitish patches, similar to those sometimes found inside the cheeks, may accompany fever, dehydration, the second stage of syphilis, thrush, lichen planus, leukoplakia, or mouth breathing.
In geographic tongue, some areas of the tongue are white or yellow and rough, whereas others are red and smooth. The areas of discoloration move around over a period of weeks to years. The condition is usually painless, and no treatment is needed.
