The difference between pityriasis versicolor and leukoplakia is that the onset sites are different

Pityriasis versicolor and vitiligo look quite similar. If you don't look carefully, it is really difficult to tell the difference between pityriasis versicolor and vitiligo. Let's take a look at the difference between pityriasis versicolor and vitiligo.

Speaking of pityriasis versicolor and leukoplakia, these two spots look quite similar. If you don't look carefully, it is really difficult to tell them apart. What is the difference between pityriasis versicolor and leukoplakia?

The difference between pityriasis versicolor and leukoplakia

Concept difference:

Pityriasis versicolor

Tinea versicolor, commonly known as tinea versicolor, is a superficial fungal disease caused by Malassezia furfur infecting the stratum corneum of the epidermis. It is generally more likely to occur in young men due to frequent activities and sweating, and failure to change clothes and dry the skin in time.

In addition, people who use corticosteroids, people who are weak, malnourished, have diabetes, and are pregnant can all induce this disease.

White spots

Vitiligo can be congenital or acquired. The occurrence of vitiligo may be caused by both internal causes and external environmental factors, such as sun exposure, chemicals, fungal infections, etc.

Difference in the site of disease onset:

The scope of leukoplakia can be localized or generalized. Congenital leukoplakia can be localized, such as anemic nevus, apigmented nevus and apigmented incontinence pigmenti, etc., or it can be systemic, such as albinism and mottled disease. The distribution of acquired leukoplakia varies depending on its cause.

Most of the areas where pityriasis versicolor occurs are round or oval spots with inconspicuous surroundings. The key point is that there are usually a lot of fine scales on the surface of pityriasis versicolor. Pityriasis versicolor mainly appears in areas where sebaceous glands are well developed, such as the neck, upper chest, back and arms. The colors range from gray, brown to yellow-brown, and sometimes multiple colors coexist, resembling spots.

The differences between tinea versicolor and vitiligo are mainly manifested in the following points

The surface of tinea versicolor often has many fine scales, which are refractive, while the epidermis of the white spots is relatively smooth.

Pityriasis versicolor is most common in areas with well-developed sebaceous glands, such as the neck, upper chest, back and upper limbs, but white spots may spread all over the body.

Pityriasis versicolor will be aggravated by excessive sweating, and leukoplakia will be affected by exposure to sunlight.

Fungi can be found in tinea versicolor under a microscope, but not in leukoplakia.

Vitiligo is caused by the loss of melanin, while pityriasis versicolor is a skin disease caused by fungi, and the skin lesions are mainly pale white.

Warm reminder: Friends suffering from these two diseases must seek treatment as early as possible to avoid delaying treatment and causing the disease to spread throughout the body, making treatment more difficult.

Note: white spots on the body are not necessarily tinea versicolor. There are many types of vitiligo. The important thing to be cautious about is the possibility of vitiligo.

This is the end of the introduction to the difference between pityriasis versicolor and leukoplakia. Come and check whether you have leukoplakia or pityriasis versicolor.
