What symptom does inside skin mole canceration have?

summary

Intradermal nevus is the most common type of pigmented nevus in adults, because the disease often has complications. It is named because the nevus cells are located under the epidermis and the superficial layer of dermis. This kind of nevus can occur in any part of the body, but the most common is in the head and neck, not in the palm, plantar and genital parts. Now let's understand with you, what are the symptoms of malignant transformation of intradermal nevus? It's a matter of time.

What symptom does inside skin mole canceration have?

First, according to the growth site, it can be divided into junction nevus, endothelial nevus and compound nevus. Early nevus or childhood nevus are mostly borderline nevus, flat nevus is often borderline nevus. After the nevus cells gradually separated from the epithelial basal layer and completely into the dermis, that is intradermal nevus. When part or most of the junctional nevus has entered the endothelium, it is called compound nevus. In adults, the vulva is often borderline nevus or compound nevus. This kind of nevus is located in the vulva which is easy to rub and stimulate. It is easy to become malignant melanoma.

Second, it is differentiated from large nevus cells, which are more mature small nevus cells and enter the dermis and its surrounding connective tissue.

Third, if there is no evidence of malignant transformation of large facial nevus, partial excision by stages can be considered. The appearance and function are well preserved, but it is not suitable for those with malignant transformation tendency. Total excision, transfer of adjacent skin flap or free skin grafting can also be used. If malignant transformation is suspected, surgical resection should be performed at one time; The incision should be made on the normal skin outside the boundary of the nevus. After the removal of the small nevus, the skin can be peeled off and sutured directly.

matters needing attention

1. Non operative therapy includes liquid nitrogen freezing, laser, electrolysis, electrocautery, high-frequency electrotome, trichloroacetic acid, carbolic acid and other chemical corrosion methods. Its principle is to use various methods to destroy the local tissue of the lesion, gradually fall off, and rely on the regeneration and repair of the surrounding tissue. Although the operation can be avoided, it is difficult to master the depth of tissue destruction, too shallow treatment is not complete and the formation of stimulating factors, too deep will leave depressed scars, and the local skin color is different from the surrounding tissue after treatment. 2. Surgical treatment of any type of nevus, regardless of size, can be applied. The curative effect is stable and reliable, and further pathological examination can be done after cutting the tissue.
