What is malignant melanoma

Malignant melanoma is a malignant tumor with a high mortality rate, which poses a serious threat to the life and health of patients. So what is malignant melanoma? Let's learn about it together.

Malignant melanoma is a tumor produced by melanocytes in the skin and other organs. Primary melanoma is caused by the proliferation of melanocytes in the epidermis, which manifests as a densely pigmented nodule that gradually increases and may be surrounded by a red halo. Although its incidence is lower than that of basal cell carcinoma and squamous cell carcinoma, it is more malignant, metastasizes early, and has a high mortality rate, so early diagnosis and early treatment are very important. Except for cases of secondary canceration caused by giant congenital nevus, which are more common in children, malignant melanoma mostly occurs.

Initially, malignant melanoma is a pigmented spot ranging from brown to black, and the color is often uneven, with different shades and irregular edges. Later, it may gradually expand and bulge into plaques, nodules or masses, and even ulcerate, bleed, and finally metastasize. Based on clinical manifestations, malignant melanoma can be divided into the following four types: melanoma in situ, superficial disseminated melanoma, nodular melanoma, and lentigo maligna melanoma.
