Malignant melanoma

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 is manifested as gradually increasing nodules with dense pigments, which can be surrounded by redness. Although its incidence is lower than that of basal cell carcinoma and squamous cell carcinoma, its malignancy is large, metastasis occurs early, and mortality is high. Therefore, early diagnosis and early treatment are important.
