What are the typical symptoms of benign melanoma?

Clinical manifestations:

Melanoma occurs in middle-aged and elderly people, more often in men than in women, and occurs in the lower limbs and feet, followed by the trunk, head, neck and upper limbs. The main symptoms are rapidly growing melanin nodules. Melanin deposition can occur on normal skin, or pigmented moles increase in pigmentation and deepen in black. Then the lesion damage expands and the hardness increases, accompanied by itching and pain. Some melanoma lesions are swollen, plaques and nodules, and some are mushroom or cauliflower-like. Subcutaneous nodules or lumps grow in the subcutaneous tissue, and star-shaped black spots or small nodules spread to the surrounding areas. Common manifestations are regional lymph node metastasis of melanoma, and even regional lymph node enlargement. In the late stage, it metastasizes from the bloodstream to the lungs, liver, bones, and brain organs.

Clinical classification:

1. Surface spread is the most common, accounting for about 70%; it occurs around the age of 50. Women mostly occur on the limbs, and men mostly occur on the trunk. The degree of malignancy is between freckles and nodules. It appears brown, brown, blue or black in the early stages. Most of them can be rose red or pink. Its edges are jagged, making the skin texture disappear. The radiation growth period lasts for 1 to 12 years. Lymph node metastasis occurs in less than 5% of cases within 12 years.

2 Freckles account for 100% to 15%; it is the least malignant of the four types and is prone to occur in exposed parts such as the head, neck, and back of the hands. It is more common in people aged 60 to 70 years old and more common in women. Clinically, it manifests as larger, flat or slightly higher than the skin surface brown or brown lesions. When radial growth is accompanied by vertical growth, the local area shows focal protrusions, and the color is still brown. The lymph node metastasis rate is about 25%.

3. Nodular type is the most malignant of the four types, accounting for 12%; around 50 years old, the male-female ratio is 2:1, and it is more likely to occur on the back. Clinically, it is a gray nodule with a pink color. When the lesion continues to grow, its color turns blue-black, and it appears like purple-black jam.
