Symptoms of toenail melanoma

Toenail melanoma is a serious disease. This type of disease is very harmful to the body and is complicated to treat. Most patients with this disease are caused by working or living under high radiation for a long time. Because a healthy living environment is very important, what are the symptoms of toenail melanoma? It has many symptoms, and the body will also feel obvious discomfort after having this disease. The following is a detailed introduction to toenail melanoma.

The symptoms of nail melanoma must be taken seriously. Terminal maculoid melanoma mainly occurs on the palms, soles and subungual areas. The lesions in the radiation growth phase are brown, brown or black and do not protrude above the skin surface. If irregular brown or brown stripes can be seen under the nail, they extend from the nail bed to the proximal end. The radiation growth phase lasts for about 1 year. If not treated in time, it will enter the vertical growth phase. The lesions are nodular and the lymph node metastasis rate also increases, and the prognosis is also poor.

What you really need to worry about with nail melanoma is that a black streak appears on only one nail, which may be a benign melanoma, subungual bleeding or malignant melanoma, or the result of repeated local trauma, friction irritation or even onychomycosis. It can be seen from this that patients with nail melanoma should always pay attention to their physical health. When they find any of the above phenomena, they must go to a regular dermatology hospital for examination and treatment in time to avoid causing chronic renal failure, which in turn threatens the life and health of patients.

The differential diagnosis includes basal cell carcinoma, seborrheic keratosis, dysplastic nevus, blue nevus, dermatofibroma, various nevus types, hemangioma (especially of the hands and feet), venous lakes, pyogenic granulomas, and warts. If in doubt, a full-thickness skin biopsy slightly beyond the lesion must be performed. Excisional biopsy is done for small lesions, and incisional biopsy is done for larger lesions. Serial biopsy sections can determine the depth of melanoma invasion, and thorough radical surgery must be performed only after a clear histological diagnosis.
