The margin includes a normal vaginal mucosa of 1 to 2 cm to prevent the tumor from spreading during biopsy. The rapid frozen examination of the resected tissue confirms the scope of the operation according to the situation. The cytological smear examination of the vagina can contribute to the rapid diagnosis of the disease. Non-epithelial malignant cells can be seen on the smear.

Differential diagnosis

Vaginal drainage is a black water-like confusing symptom differential diagnosis:

Vaginal melanoma should be distinguished from other rare melanoma-containing tumors such as pigmented neurofibromas and malignant schwannomas. The types of vaginal melanoma cells are diverse, especially the non-pigmented vaginal melanoma is easily misdiagnosed with squamous cell carcinoma, vaginal adenocarcinoma and sarcoma. The rate of misdiagnosis is 20%. It was mainly identified by immunohistochemical staining and electron microscopy and other diseases. Electron microscopy was more accurate than HMB-45 staining. It should also be thought of distinguishing from the rare vaginal mucosa melanin, and excluding metastasis of other sites and malignant melanoma of adjacent organs. The change of mucosal junction is the most reliable basis for proving the primary.
