Among the many tumor diseases, melanoma is actually one of them. If melanoma is not treated in time, it will cause malignant transformation. So, what are the early symptoms of melanoma ? Next, let's learn about it from the following article. 1. 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 an early symptom of melanoma. 2. 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, sometimes a small number of paget-like melanocytes can be seen in the upper part of the epidermis as early symptoms of melanoma. 3. Nodular melanoma is 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, sometimes arranged in bundles. This is also an early symptom of melanoma. The above is a detailed description of the early symptoms of melanoma. I hope it can help everyone understand the knowledge of melanoma in this regard and cure melanoma in time.
