What abnormal clinical symptoms do melanoma patients have?

Melanoma is a rare malignant tumor that mainly originates from epidermal melanocytes or pigmented nevi. So, what are the common clinical symptoms of melanoma? Today, let the experts tell us in detail about the clinical symptoms of melanoma .

The main clinical symptoms of melanoma are:

1. Ulceration is a clinical symptom of melanoma that is different from moles, and it also has prognostic significance. The ulcerated type has a worse prognosis than the non-ulcerated type.

2. Patients with malignant melanoma are generally older, and melanoma is rare in young people or children. For general tumors, age is only statistically significant, but in melanoma cases, age sometimes becomes one of the important bases for diagnosis.

3. The surface of a mole is generally smooth, while the surface of a melanoma is relatively rough. If a mole that was originally smooth suddenly becomes rough or nodular, you should be careful. Moles can be very dark in color, while melanoma can be very light in color or contain no pigment. If the pigment is unevenly distributed, and the lesion area is rich in blood vessels, and there are satellite nodules or pigment diffusion on the periphery, you should be vigilant.

In terms of texture, moles are soft and tough, while melanomas are hard and brittle. Since the epidermal cells of melanomas can dissolve and rupture on their own, the presence of cracks or ulcers on the surface is a manifestation of its malignant nature. Even if ulcers have not yet formed, bleeding without reason is also a dangerous signal.

Hairy moles are intradermal moles, which rarely become malignant. However, if a hairy mole sheds hair on its own, it indicates that there is an active lesion at the junction of the epithelium and dermis of the hair follicles. This type of mole may become malignant, so you should be alert. Follow-up observation or excision and biopsy should be performed.
