White spots at the corners of mouth

The symptoms of white spots at the corners of the mouth are highly consistent with the characteristics of vitiligo, and should be taken seriously once they occur. Vitiligo is a very harmful skin disease that currently cannot be cured. However, early detection of vitiligo helps us control the disease and prevent it from spreading too quickly to other parts of the body. Let’s learn more about vitiligo and see if our condition is caused by this disease.

Vitiligo is usually first seen on the face and neck, with a small area, smooth surface, and no pain or itching. These are considered early symptoms of vitiligo. The white spots that appear on your face now should be considered as early symptoms. You should seize the opportunity to go to the hospital for examination and treatment. The earlier the treatment, the better the effect, which can control the spread and increase in the number of white spots. Otherwise, the area will expand, the spots will increase, local redness will occur, itching will be unbearable, and peeling will occur, affecting normal life. Vitiligo is hereditary. If there are vitiligo patients within three generations of direct or collateral relatives, the chances of other members getting the disease are higher than those of the normal population.

Differential diagnosis 1. Anemic nevus occurs in childhood and is mostly seen on the face. It is a light-colored spot that does not turn red when stimulated or rubbed, but the surrounding skin turns red. 2. Pityriasis alba may be related to dry skin and sun exposure, and manifests as hypopigmented spots with unclear edges and a small amount of white scales on the surface. 3. Non-pigmented nevus occurs at birth or shortly after birth. The skin lesions are localized pale white spots with jagged edges. 4. Tinea versicolor lesions occur on the trunk and upper limbs. They are pale white round or oval spots with unclear boundaries and fine scales on the surface. Fungal tests are positive. 5. Albinism is a congenital non-progressive disease, often with a family history. The skin and hair all over the body lack pigmentation, the irises of both eyes are transparent, and the choroidal pigment disappears, making it easy to distinguish from vitiligo. 6. Leprosy leukoplakia is an incomplete hypopigmented macules with unclear borders, loss of surface sensation, and other symptoms of leprosy. 7. The leukoplakia of secondary syphilis occurs on the neck, is not pure white, and the syphilis serum reaction is positive. 8. Other diseases should also be differentiated from discoid lupus erythematosus, mucosal leukoplakia, etc.
