What is the basis for diagnosing melanoma

What are the common diagnostic methods for melanoma? Many people are familiar with melanoma. Because its early symptoms are not obvious, many patients fail to discover the disease in time, delaying treatment and causing serious consequences. Therefore, it is very necessary to understand the diagnostic methods of melanoma. You can make a confident judgment first. If you want a more accurate diagnosis, you should go to the hospital for examination. The following is a detailed introduction for you.

1. Staining can show melanoma; melanosomes can be seen under electron microscopy; immunoenzyme labeling (S-100) is positive, which also belongs to the diagnosis of melanoma.

2. Junctional nevi should be closely observed. If a nevus grows rapidly in a short period of time, the pigmentation darkens significantly and spreads around, or the hair on the nevus suddenly falls off on its own, or the nevus feels itchy, or granular satellite nodules appear around the nevus, and the lymph nodes in the area are swollen, these are all basis for the diagnosis of melanoma.

3. Anyone with pigmented nodules or pigmented nodules showing ulcerous manifestations should be highly suspected of the possibility of this disease, which also helps in the diagnosis of melanoma.

4. Biopsy pathological examination shows that epithelioid tumor cells, spindle tumor cells, and melanin components are mixed under the microscope, with complex structure and diverse morphology. This is a good method for diagnosing melanoma.
