What reason is long mole caused?

summary

Many people don't know what causes a long mole. In fact, nevus is a large nevus cells continue to differentiate. Nevus is a more mature small nevus cells, these cells into the dermis and the surrounding connective tissue, and then continue to grow, and finally form a nevus. The types of nevus include borderline nevus, intradermal nevus and compound nevus.

What reason is long mole caused?

Intradermal nevus is a common kind of nevus. This kind of nevus is generated by the continuous differentiation of large nevus cells. In essence, it belongs to more mature small nevus cells. These small nevus cells can enter the dermis and the surrounding connective tissue, and then continue to differentiate and grow, and finally form intradermal nevus.

Borderline nevus is also a kind of common nevus. This kind of nevus is the continuous growth of nevus cells at the junction of the epidermis and dermis of patients. At the beginning, the nevus cells show a nest like shape, with clear boundary and uniform distribution on the skin. Each nevus has an epidermis layer inside, and the epidermis layer is embedded into the superficial dermis layer. Most of these nevus cells are developed from large cytoplasm cells, Its pigment content is more, so the color is deeper.

Compound nevus is another kind of nevus, this kind of nevus is nevus cells into the dermis of the skin, in this process often form intradermal nevus and a small number of residual border nevus. Therefore, compound nevus can be regarded as a mixture of intradermal nevus and borderline nevus.

matters needing attention

In fact, the growth of nevus is the result of the continuous differentiation of nevus cells. There are normal melanocytes inside the nevus, and the possibility of canceration is very low. However, if the nevus is subject to external stimulation, friction or other stimulation, it may become malignant. Therefore, we must pay attention to the nevus. People with nevus should not scratch and stimulate the skin, It's best to go to the hospital regularly for examination. If itching, pain, redness and other symptoms are found in the near future, they should seek medical examination at the first time. Once the signs of malignant transformation are found, they should be treated immediately.
