Nasal melanoma can be treated surgically, with radiotherapy, chemotherapy, and immunotherapy. Early detection should be based on surgical treatment to control the progression of the disease, reduce toxic side effects, and prevent metastasis and spread of the tumor. Nasal melanoma is a malignant tumor originating in the nasal cavity and derived from pigment cells. The disease is highly malignant, difficult to diagnose at an early stage, difficult to treat thoroughly, and has a poor prognosis, making it one of the clinically difficult diseases to treat. For malignant melanoma, preoperative biopsy is generally not advocated, because biopsy may promote the rapid spread of tumor cells. When encountering nasal neoplasm with dark color, black, purple-brown or light red, nodular, cauliflower or polyp-like appearance and easy bleeding when touched, the clinical diagnosis of nasal malignant melanoma can be made by excluding malignant melanoma of other tissues.
