Patients with pigmented skin diseases should be alert to melanoma

Pigmented skin diseases often develop into melanoma. As a skin cancer with high malignancy, easy blood metastasis and high mortality rate, it is crucial to understand the symptoms of melanoma, detect it early and treat it early. Here, we specially invite relevant experts to introduce the symptoms of melanoma to you in detail.

One is the asymmetry of the rash. One side of the rash is relatively stable, while the other side expands outward and becomes irregular and rough on the surface, which is often a symptom of melanoma.

Second, the rash pigmentation deepens or decreases. It can be light brown, dark brown, black, dark red, red, purple, gray-green, cyan, gray-blue, or even disappear.

3. Another symptom of melanoma is that the border around the rash is unclear, or one side is clear and the other side is blurry, giving people a vague feeling.

Fourth, the rash grows rapidly in a short period of time. It doubles in size within 1 to 2 months. If the diameter of the congenital nevus rash is greater than 6 mm, especially if it occurs on the palms and soles, if the diameter of the nevus exceeds 15 mm, it indicates the possibility of malignancy.

5. A relatively rare symptom of melanoma is a raised rash. The rash is not raised at first, but then slightly raised and gradually forms nodules. Or there may be erosion, scabs, pus, or water on the surface, especially blood.

6. Some subjective symptoms are also danger signals, such as itching, pain, burning sensation, redness and swelling, or the appearance of new small black spots (satellite lesions) within 2 cm around the mole. Especially moles growing on friction sites such as palms, soles, fingernails (toenails), waist, shoulders, etc. should not be ignored.

The symptoms of melanoma vary depending on the living and working environment of patients with pigmented skin diseases. In order to effectively prevent melanoma, we must know both ourselves and the enemy.
