The histopathological morphology of early symptoms of malignant melanoma varies with different types. What are the early symptoms of malignant melanoma? The following is an expert's introduction to the early symptoms of malignant melanoma.

What are the common early symptoms of malignant melanoma ? Below is an introduction to the specific early symptoms of malignant melanoma.

1. Nodular melanoma is an early symptom of malignant melanoma in which atypical melanocytes proliferate vertically downward and invade the dermis without invading the epidermis. Epithelial cell-type melanocytes are often arranged in alveoli; spindle cell-type melanocytes are similar to fibroblasts, sometimes arranged in bundles.

2. In malignant lentigo melanoma, the epidermis atrophies, there are many atypical melanocytes in the basal layer, and the dermis is invaded downward. The early symptoms of malignant melanoma are that the phagocytes in the tumor cells or in the intercellular matrix contain a considerable amount of melanin.

3. Superficial spreading melanoma has irregular proliferation of the epidermis downward, 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 in the early stage of malignant melanoma.

4. The early symptoms of malignant melanoma include: acral freckles, melanoma, epidermal thickening, atypical melanocyte nests containing a large amount of pigment 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 papillae.
