summary

Psoriasis is a common skin disease in our daily life, but it is difficult to treat psoriasis. Patients with psoriasis should be treated as soon as possible. My cousin suffers from psoriasis. Now I will tell you how to identify psoriasis and anemia nevus.

How to distinguish psoriasis from anemia nevus

First of all: psoriasis is a depigmentation disease of skin, mucosa and hair caused by the obvious reduction or loss of melanocytes. Psoriasis lesions are generally pure white, while anemia nevus lesions are pale white.

Second: psoriasis and anemia nevus are fundamentally different. Due to the normal function of blood vessels in the lesion area of psoriasis, local congestion will be caused by rubbing or patting, which will make the lesion red. On the contrary, anemia nevus can not cause congestion reaction after rubbing.

Finally: the pigmentation in the lesion area of anemic nevus is normal, so the normal skin around the lesion is difficult to distinguish from the lesion because of the same color after being pressed and bled by the slide, so that the lesion disappears, and psoriasis will not have this phenomenon.

matters needing attention

Patients should be treated as early as possible to avoid the occurrence of complications. Anemia nevus is a congenital localized vascular developmental defect. The structure of blood vessels in the affected area is normal, but the function is defective. The sensitivity of blood vessels to catecholamine is enhanced and the skin is in a state of contraction, which makes the skin pale.
