Classification and introduction of clinical symptoms of malignant melanoma

The clinical symptoms of malignant melanoma are quite complicated, so experts have classified them into many types, which is conducive to the diagnosis and treatment of malignant melanoma. Now, let the experts introduce the clinical symptoms of malignant melanoma to us.

Different types of malignant melanoma have different clinical symptoms:

1. Spreading type. This type has a superficial eczematous appearance and is mostly developed from the infiltration of in situ melanoma. The skin around the tumor has eczematous changes. The edges of spreading eczematous malignant melanoma are irregular, the surface is uneven, and it is gray-black, gray-white, light red and other messy colors.

2. Freckle type. This type is mostly developed from lentigo maligna in situ. The epidermis near the tumor has freckle-like characteristics. Its edges become extremely irregular, but the surface is flat, and the color is mostly brown to varying degrees, which can also be similar to the spreading type. This type often occurs on the basis of facial freckles in the elderly, but it is less common in my country.

3. Special type: The tumor is located deep in the dermis and subcutaneous tissue, is in the form of small nodules, has clear boundaries, but has no capsule, is grayish white or grayish blue, is hard, and is often accompanied by local lymph node metastasis.

4. Nodular type. This type is the most common clinically. The clinical symptoms of malignant melanoma are that the tumor is nodular and protrudes from the skin surface. The color is relatively consistent, dark brown or gray-red, and occasionally colorless. The surface of the tumor is mostly regular, or cauliflower-like, or polyp-like, or fungus-like. Ulcers often occur on the surface. The tumor often increases rapidly in a short period of time, ranging from several centimeters.
