Pseudoleukoderma

Pseudo-leucoderma (pseudoleucoderma; pseudo- + leucoderma; synonym: secondary leucoderma, false leucoderma) is a condition in which depigmented spots appear on the skin, reminiscent of manifestations of leucoderma, but having a different nature.

Unlike true leukoderma, in pseudoleukoderma, skin depigmentation is not caused by a dysfunction of melanocytes and their lack of production of the melanin pigment, but is a consequence of damage to the basal layer of the epidermis.

The causes of pseudoleukoderma can be different: injuries, burns, fungal and bacterial infections, prolonged use of irritants, etc.

To make a diagnosis of pseudoleukoderma, it is necessary to exclude true leukoderma. Treatment is aimed at eliminating the factor that caused depigmentation and stimulating skin regeneration.

Pseudo-leukemia: what is it?

Experts call pseudoleukemia a condition in which a person notices redness on his body. They can be very similar to the manifestations of true leukoderma (usually red spots on the skin with mild pigmentation). **These lesions are not always painful and itchy like other types of leukoderma.**

The most common cause of such pigmentation changes is external exposure to the sun or ultraviolet rays. This happens when they get on the skin and affect the melanin pigment. Thus, at the very beginning we can only talk about the manifestation of the harmful effects of external factors on the skin.

But under the sun, a person can get a disease called true leukoderma. In such a situation, redness and pigmentation of the skin is a clearly visible symptom.

The process of the appearance of such pigmentation causes pigment-triggering receptors, which are responsible for accelerating the process. The acceleration process naturally affects the process of removing excess pigment from the skin. Based on this, it is worth understanding that pseudoleukemia cannot be equated with classical leukoderma.
