Top ten conditions for diagnosing malignant melanoma

Malignant melanoma and mole are easily confused by us, so we need to understand the conditions for diagnosing malignant melanoma so that we can do the earliest diagnosis work ourselves. Now let the experts tell us in detail the conditions for diagnosing malignant melanoma .

The conditions for diagnosing malignant melanoma are usually:

1. Atypical tumor cells break through the basement membrane and enter the dermis;

2. The anaplastic changes of tumor cells may be heterogeneous, mainly characterized by enlarged and darkly stained nuclei and cells of varying sizes;

3. Atypical proliferation of tumor cells at the junction of active epidermis and dermis. The cells are scattered and not in nests, or the nests are fused. There is continuous proliferation of atypical melanocytes in the basal layer between the epidermal protrusions.

4. Except for Spitz nevus, all nevus cell tumors have no nuclear division phase in the dermis. If there is nuclear division phase, it is often a sign of malignant melanoma.

5. Tumor cells spread throughout the entire epidermis;

6. Immature cells, that is, the tumor cells do not gradually become smaller or longer from the dermis to the deep layer;

7. In the deep layer of intradermal nevus, dense reticular fibers can be seen surrounding single scattered nevus cells, while the stromal reaction of malignant lesions is milder;

8. Increased melanin formation;

9. Leather belt-like inflammatory infiltration;

10. Surface ulcers form.
