Vaginal melanoma should be differentiated from other rare melanin-containing tumors such as pigmented neurofibroma and malignant nerve sheath tumor. Vaginal melanoma has various cell types, especially non-pigmented vaginal melanoma, which is easily misdiagnosed as vaginal squamous cell carcinoma, vaginal adenocarcinoma and sarcoma, with a misdiagnosis rate of 20%. It is mainly differentiated from other diseases by immunohistochemical staining and electron microscopy. Electron microscopy is more accurate than HMB-45 staining. It should also be considered to differentiate it from the rare vaginal mucosal melanocytic nevus, and exclude metastatic tumors in other parts of the body and invasion of malignant melanoma in adjacent organs. Changes in the mucosal junction are the most reliable basis for proving primary.

Vaginal melanoma has typical clinical presentation. Vaginal lesions found during gynecological examinations are relatively easy to obtain clinical diagnosis. Suspicious cases can be pathologically examined by punch biopsy or resection of the full-thickness lesions. The resection margin includes 1 to 2 cm of normal vaginal mucosa to prevent the spread of the tumor during biopsy. After confirmation by rapid freezing examination of the excised tissue, the scope of surgery is expanded according to the situation. Vaginal cytology smear examination can help to quickly diagnose the disease. The smear may show non-epithelial malignant tumor cells.
