Symptoms of late-stage melanoma

Melanoma originates from melanocytes, which are evenly distributed under our skin. Melanoma has no obvious symptoms in the early stages, and is often diagnosed in the late stages. So what are the symptoms of late-stage melanoma ? The following is a detailed answer from relevant experts.

① Nodular type The nodular type is the most common in clinical practice. The tumor is nodular and protrudes from the skin surface. The color is relatively uniform, usually dark brown or gray-red, and rarely colorless. The surface of the tumor is mostly polyp-like, cauliflower-like or fungal, and ulcers often occur. The tumor can quickly increase by several centimeters in a very short period of time. This is a relatively obvious late-stage symptom of melanoma.

② The edges of spreading malignant melanoma are irregular, the surface is uneven, and it is grayish white, light red, grayish black and other mixed colors. This is a late symptom of melanoma.

③Special type: The lesions are small nodules with clear boundaries, no capsule, grayish white or grayish blue in color, and hard in texture.

④ Freckle type is mostly developed from malignant lentigo in situ. The epidermis near the tumor has freckle-like characteristics, the surface is flat, the edges are extremely irregular, and the color shows different degrees of brown, which is sometimes similar to the spreading type. This type usually occurs on the basis of facial freckles in the elderly and is relatively rare.
