There is a white spot on the back

People always have some minor skin problems, sometimes caused by allergies, and sometimes due to the body's own problems. For example, eating irritating foods or eating things that are allergic can cause skin diseases. Many people will have white spots on their backs. There are many reasons for this phenomenon. Let us take a look at the reasons for the white spots on the back.

Generally speaking, the white block and normal skin are clearly demarcated, but if it is in the progress stage, the edge of the white block may appear blurred. Sometimes a diffuse halo with a color between normal skin and the white block may appear around the white block. The hair in the white block can be white, normal, or black and white. The treatment effect is relatively poor if the hair turns white. After the white block disappears, the hair can also turn black.

Generally speaking, the surface of the white block is smooth, without scales or scabs, and the sensation and secretion function are normal. However, a small number of patients feel itchy in the white spots, and some even feel severe itching. In this case, the white spots can be seen as they develop and take effect. In addition, a small number of vitiligo patients secrete sweat with an odor in the white spot area.

You can observe whether the white spots on the back are depigmented spots, which are usually milky white or light pink, with a smooth surface and no rash. The boundaries of the white blocks are clear, the pigmentation at the edges is increased compared to normal skin, and the hair inside the white blocks is normal or whitened. The lesions often occur in areas exposed to sunlight and damaged by friction, and are often distributed symmetrically. If so, it may be vitiligo, but it is recommended that patients use a Wood's lamp to confirm whether they have vitiligo.

White spots on the back may be vitiligo, dermatitis, post-inflammatory depigmentation, tinea versicolor caused by fungal infection, etc. If the skin is itchy or has an inflammatory rash, it may be dermatitis. If white patches of skin appear with dandruff, it may be tinea versicolor caused by a fungal infection. If the surface of the white block is smooth and does not peel off, and the white block spreads to the periphery, it is generally more likely to be vitiligo. In terms of the specific situation, you need to go to a regular hospital for a doctor's examination and professional examination to make a clear diagnosis, and then carry out targeted treatment to cure the disease.

Whether the surface of the white block is smooth and free of dandruff, and the white block is light white or milky white, if the boundary is blurred or spreads towards the normal skin, it may be vitiligo. The specific situation needs to be diagnosed only after seeing the white block. Vitiligo is a difficult disease to treat. Its biggest feature is that it is easy to spread, especially affecting appearance and life.
