How to identify the characteristics of early symptoms of melanoma

Although the incidence of melanoma is increasing, many people still do not know the early symptoms of melanoma. Experts say that treatment of early symptoms of melanoma is very beneficial to patients. The following is an expert's introduction to the early symptoms of melanoma.

1. Superficial spreading melanoma is characterized by irregular proliferation of the epidermis, 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. Early symptoms of melanoma include obvious infiltration of dermal inflammatory cells.

2. Nodular melanoma is atypical melanocytes that proliferate vertically downward and invade the dermis, but not the epidermis. This is one of the early symptoms of melanoma. Epithelial cell-type melanocytes are often arranged in alveoli; spindle cell-type melanocytes are similar to fibroblasts, sometimes arranged in bundles.

3. Lentigo maligna melanoma has atrophy of the epidermis, with more atypical melanocytes in the basal layer, and invades the dermis downward. The pigment-eating cells in the tumor cells or in the interstitial matrix contain a considerable amount of melanin. This is one of the early symptoms of melanoma.

4. Acral lentigo melanoma is characterized by thickening of the epidermis, and nests of atypical melanocytes containing a large amount of pigment are located in the lower part of the epidermis. Spindle melanocytes are common in the early stages of melanoma.
