For the judgment of melanoma as a malignant tumor, it cannot solely rely on clinical experience. Instead, the skin lesion should undergo surgical excision. During the surgery, freezing can be scheduled, and the results of the freezing report will determine the scope of the surgery.

The final diagnosis still depends on the paraffin section. The diagnostic gold standard is based on the pathological results, and only a pathology examination can determine whether the lesion is a malignant melanoma. Diagnosing such diseases requires extreme caution due to their high malignancy and ease of metastasis, which can endanger life. Standardized surgical excision is necessary, supplemented by chemotherapy and other methods.
