Pigless nevus and vitiligo are two relatively similar skin white diseases. Many patients will confuse pigmentless nevus and vitiligo in the early stage. So, what is the difference between pigment-free moles and vitiligo? Let me give you a detailed introduction to , Director Wang of , Shijiazhuang Yuanda Vitiligo Hospital.
The difference between pigment-free nevus and vitiligo
Picture-free nevus: This disease occurs shortly after birth or occurs. The color is often not very white, the edges are blurry, and usually jagged, and the surface is not very smooth when touched. It is usually fixed to a certain part for life and will not grow any longer in other parts.
Vitiligo: This disease is caused by acquired loss of skin pigment and will not occur at birth, but infants can develop the disease. The color is light in the early stage, and it will become whiter as the disease develops, and it will easily develop and spread. The surface is smooth without dander and atrophy.
The difference between pigment-free mole and vitiligo: the surface of pigment-free mole is not very smooth, and the surface of vitiligo is smooth. Pigmentless nevus will not spread, vitiligo can spread easily; pigmentless nevus may be born, vitiligo is an acquired disease. These are the obvious differences between pigmented moles and vitiligo.
The pigment-free mole and vitiligo are difficult to distinguish between
Although pigment-free mole and vitiligo are certainly different, it is difficult to distinguish between vitiligo only through the naked eye. It usually requires the diagnosis with the help of equipment examination. For example, Wood lamp irradiation examination can distinguish pigment-free moles from vitiligo. Our hospital uses a Wood lamp imported from Germany, which directly irradiates white spots. The pigmented mole will be off-white or yellow-white, and vitiligo is pure white and fluorescent.
Warm reminder: If the patient is vitiligo, he must be treated as soon as possible, because the disease is prone to spread and has great harm. Usually, comprehensive examinations such as American 3D skin CT and blood test are required before treatment. Only after you have a clear understanding of the causes and conditions of vitiligo can you provide targeted treatment.
