The main symptoms of melanoma are itching, bleeding, ulcers, and tenderness, and the onset of the disease is age-related. The mortality rate of malignant melanoma in particular is very high, so early detection is very important. This is the only way to get timely treatment, but many friends don’t know how to check it. In fact, there are many ways to check, so how should we check it? 1. Benign junctional nevus. Microscopically, benign large nevus cells are seen, with no atypical cells, growing only in the dermis, and no obvious inflammatory reaction. 2. Juvenile melanoma. It appears as a slowly growing round nodule on the face of a child. Microscopically, the cells are pleomorphic and have nuclear divisions. The tumor cells do not infiltrate the epidermis, and no ulcers form on the surface of the tumor. 3. Cellular blue nevus. It is common in the buttocks, coccyx, and waist. It appears as light blue nodules with a smooth and irregular surface. Under the microscope, dark black cells with dendritic processes and large prismatic cells can be seen, which are aggregated into cell islands. When there are nuclear division phases or necrotic areas, the possibility of malignancy should be considered. 4. Basal cell carcinoma. It is a malignant tumor of epithelial cells, which infiltrates from the basal layer of the epidermis to the deep layer. The cancer nest is surrounded by a layer of columnar or cubic cells. The cancer cells are darkly stained and have no fixed arrangement. The cancer cells may contain melanin. 5. Sclerosing hemangioma. The epidermis is hyperkeratotic, the dermis is papillary, and the dilated capillaries are often surrounded by downward-extending epidermal processes, resembling an intraepidermal hematoma. 6. Age mole. It is seen in the elderly as a wart-like nevus with hyperkeratosis of the epidermis, thickening or atrophy of the granular layer, hypertrophy of the spinous layer, and an intact basal layer. There may also be increased pigmentation and proliferation of dermal papillae, giving the appearance of papilloma-like hyperplasia. 7. Seborrheic keratosis. The lesions also show papilloma-like hyperplasia, with clear subepidermal boundaries, incomplete keratinization, and the granular layer first thickens and then thins or even disappears. The proliferating epidermal cells may contain a small amount or a large amount of melanin. 8. Subnail bed hematoma. Most cases have a history of trauma, and microscopy shows dried blood cells and possible proliferation of epithelial fibroblasts. The above introduces how to examine people with black tumors who have internal heat and toxicity syndrome and liver and kidney yin deficiency syndrome. Doctors remind everyone that the cause of this disease is relatively complicated, so it is recommended that you go to the hospital for examination before treatment. Do not blindly use drug treatment, otherwise the harm will be very great! |
