It is necessary to recognize the early symptoms of melanoma

I believe that most people don’t know much about melanoma. It is also a type of tumor with a relatively high mortality rate. Knowing the early symptoms of melanoma can help detect melanoma in time. So what are the early symptoms of melanoma ? The following is a detailed answer from relevant experts.

1. The epidermis of malignant lentigo melanoma atrophies, and there are many atypical melanocytes in the basal layer, which invade the dermis downward. The chromatophores in the tumor cells or in the intercellular matrix contain a considerable amount of melanin.

2. Superficial spreading melanoma: The epidermis protrudes irregularly downwards, and atypical nevus cell nests can be seen at the dermal-epidermal junction and in the dermis. In addition to epithelial cell-type and spindle cell-type melanocytes, a few paget-like melanocytes can sometimes be seen in the upper part of the epidermis. These are all early symptoms of melanoma.

3. Nodular melanoma: atypical melanocytes proliferate vertically downward and invade the dermis, but not the epidermis. Epithelial cell-type melanocytes are often arranged in alveoli; spindle cell-type melanocytes are similar to fibroblasts, sometimes arranged in bundles.

4. Acral lentiginous nevus melanoma has thickened epidermis, atypical melanocyte nests containing a large amount of pigment are located in the lower part of the epidermis, spindle-shaped melanocytes are common, paget-like melanocytes can also be seen in the upper part of the epidermis, and chromatophagocytes can be seen in the dermal papilla.

The above is an introduction to the early symptoms of melanoma. If you experience the above symptoms, you must go to the hospital for treatment in time. If you want to know more about melanoma, please consult an online expert.
