Anemic leukoplakia, also known as anemic nevus, is a hereditary disease associated with chromosomal inheritance as well as other hereditary disorders, and can appear as light white patches.
Catecholamines in the body cause capillary constriction, which can cause localized ischemia of the skin to whiten, and when this occurs over a long period of time, white patches can form.
The condition is a congenital genetic disorder, and current research suggests that it is autosomal dominant. Other hereditary diseases, such as tuberous sclerosis and hyperpigmented vascular trichotillomania, can co-occur with anemic nevi.
Anemic nevi occur in areas other than the limbs, especially on the face and chest, and may appear as densely distributed small macules with a pale white color, similar to the white color of fingertips appearing from ischemia.
If you suspect that you have an anemic nevus, it is recommended that you go to the hospital in time to get a clear picture of the cause of the disease, so as not to delay your condition.
