Sometimes early melanoma symptoms are arranged in bundles

As the incidence of melanoma continues to rise, many people have begun to pay attention to the early symptoms of melanoma. So, what are the common early symptoms of melanoma ? The following is a detailed introduction by experts on 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 characterized by atypical melanocytes that 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, and sometimes arranged in bundles.

3. 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.

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.
