Melanoma symptoms?
summary
Melanoma refers to the malignant change of pigmented nevus, which is developed from the borderline nevus or mixed nevus. Although it may not be malignant, chronic stimulation and inappropriate treatment are closely related to the transformation of nevus into melanoma. Heel is the most common site, followed by head, neck and extremities. Most cases metastasize to regional lymph nodes, and can also be hematogenous metastasis. The clinical diagnosis was based on pigmentation, clinical symptoms and whole specimen biopsy. The best treatment is surgical resection. Melanoma symptoms? Let's talk about it
Melanoma symptoms?
Melanoma is a malignant tumor originated from cells that can produce melanin. It is characterized by sudden appearance or rapid growth of nevus, deepening of color, cometary tumor or pigment ring around, local pain, infection, ulcer or bleeding, and swollen lymph nodes. Most of the tumors occurred in lower limbs, followed by head, neck, upper limbs, eyes, under nails and labia. In the early stage, it can be transferred to the liver, brain, bone, mucosa and so on. There is a close relationship between the disease and nevus. Moles on the palms, soles, eyes and at the junction of epidermis and dermis, which are often rubbed, are prone to malignant transformation and are considered to be the precursor of melanoma.
Melanoma is also called malignant melanoma. It is a skin tumor related to orthopedics and traumatology. Benign melanoma, also known as pigmented nevus, often does not attract attention. Melanoma can be malignant at the beginning, but usually from the junction nevus. This is a kind of tumor with high degree of malignancy, which is more common. The ratio of male to female is 2:1. The most common sites were lower limbs and feet,
The second is the upper limbs, head and neck, trunk and so on. The cause of the disease is still unknown, but some cases have a history of skin injury, burn and X-ray irradiation may be the inducement, a few cases are related to endocrine factors, and familial tendency has also been reported. The tumor was gray black, nodular, soft and sometimes ulcerated. Microscopically, the tumor cells were fusiform, round or polygonal in shape. There were different amounts of melanin granules in the cytoplasm. The appearance was black. The tumor cells were different in size and arranged in diffuse, nest, adenoid or trabecular shape. Whether the tumor has metastasis or not, it should be treated in time
