The most common pathological types of vulvar cancer are as follows: 1. The most common type of vulvar cancer is mainly squamous cell carcinoma, which accounts for 80-90% of vulvar cancer and is mostly seen in older women, and it mainly manifests as ulcers and nodules on the outside. Melanoma: It is more common, but is located in the second place of tumors, and comes from the malignant transformation of vulvar nevus pigmentosa. The appearance is tan or blue-black elevated flat nodules, which may appear as polyp-like or papillary nodules, and advanced tumors may appear as ulcers. In 10% of patients, the lesions do not contain melanocytes, and the appearance is similar to squamous epithelial carcinoma in situ of vulvar cancer, this part of patients is non-pigmented malignant melanoma of vulva; 3.basal cell carcinoma: basal cell carcinoma is a very rare type of vulvar cancer, accounting for 2%-3% of vulvar malignant tumors, its clinical manifestations are similar to squamous carcinoma, but because the malignant rate of basal cell carcinoma is low, its growth is slow and its course is long. 4.Vestibular adenocarcinoma: The age of onset of vulvar vestibular adenocarcinoma is small, the median age is 45-55 years old, it mainly presents as a smooth swelling in the vulvar vestibular gland, a few of them can be secondary to infection or have ulcers on the surface of the tumor, the size of the tumor is 2-5 cm, especially the vestibular gland cysts that have been growing for many years continue to increase, it is necessary to 5.Vulvar cystic adenocarcinoma of the vestibular gland: the tumor grows slowly and has a long course, mainly from local infiltration, often along the perineural and lymphatic infiltration, inguinal metastasis is rare, only 10% of patients have metastasis; 6.Paget’s disease of vulva, vulvar cancer is mainly squamous cell carcinoma: squamous cell carcinoma accounts for 80%-90% of vulvar cancer, mostly seen in older women. It mainly manifests as ulcers and nodules on the exterior.
