The cause of melanoma is cell changes

The cause of melanoma is cell changes. So what kind of changes will occur in cells due to the cause of melanoma ? In fact, there are quite a lot of these changes. Let the experts answer these questions for us. I hope that reading this article will be helpful to you.

The lesions caused by the cause of melanoma often occur at the junction of the dermis and epidermis. The tumor cells are similar to nevus cells, but are obviously atypia. The intercellular matrix and cells are full of melanin. According to the differences in cell morphology and the amount of melanin, melanoma can be divided into 5 types according to the cause:

1. Large epithelioid cells are common and are polygonal in shape. This is a change caused by the etiology of melanoma.

2. Small epithelioid cells have large and atypical nuclei. This is a change caused by the cause of melanoma.

3. The cytoplasm of spindle cells is fibrillar and the nuclei are large and darkly stained.

4. The abnormal cells are mononuclear or multinuclear.

5. Dendritic cells are larger than normal melanocytes, with atypical nuclei. Tumor cells show a strong positive reaction to casein. When they contain little melanin, it is difficult to confirm in HE sections, so it is called "amelanotic melanoma". However, if silver staining is used, melanin can still be detected in a few cells.

The above is the knowledge about the cause of melanoma introduced by experts. I hope it can help you. If you still want to know what precautions to take, please consult experts online. They will give you a satisfactory explanation. Thank you for your support and trust in this website.
