If sarcoma grows in the vaginal opening, the nature of the tumor should be judged first. If colposcopy and biopsy of the tumor are not malignant, observation can be done without abnormalities. If colposcopy finds that the tumor surface is protruding or even ulcerated or bleeding, it should be considered whether it is malignant, and it is suggested to remove the tumor directly locally and then do pathological examination. 1. Benign tumor 1. Vulvar papilloma: It is a tumor of epithelial origin and is a benign tumor of vulva. The etiology of this disease is unknown and may be related to viral infection and chronic inflammatory stimulation, manifesting as vulvar papillary masses, which are mainly treated by surgical excision and generally have a good prognosis. 2. vulvar fibroma: a benign tumor of vulva composed of fibroblasts, often solitary, mostly located in the labia majora, initially as subcutaneous hard nodules, which can then increase in size and form smooth, hard, band-like tumors. It starts as a subcutaneous hard nodule, and then can increase in size to form a smooth and hard mass with a tip. The main treatment is surgical excision. 3. Vulvar sweat gland tumor: Vulvar sweat gland tumor is a tumor formed by the proliferation of sweat gland epithelium, which is less common and is generally benign and rarely malignant. In principle, biopsy should be done first, and then local excision should be performed after diagnosis, which has a good prognosis. 4. Vulvar smooth muscle tumor: it is a benign tumor derived from smooth muscle of vulva, hair follicle standing hair muscle or vascular smooth muscle. Malignant tumors 1. Vulvar melanoma: manifesting as genital itching and bleeding, the scope of pigmentation gradually increases, the lesion is usually located in labia minora and clitoris, early looks like a mole-like nodule with pigmentation and accompanied by ulcers, treatment is mainly surgery and chemotherapy; 2. Vulvar basal cell carcinoma: the lesion is mostly local infiltration, easy to recur, slow growth, rarely metastasized, common site is labia majora, also can be in Patients feel local itching or burning sensation, or they may be asymptomatic, and surgery is the main treatment. In the middle and late stage, the vestibular adenocarcinoma is ulcerated and ulcers appear. Combined infection may appear, accompanied by abscess, exudate or bleeding, and surgery is the main treatment. Mostly seen in elderly patients, the treatment principle of this disease should be radical excision of vulva, and inguinal lymph node dissection of the same side can also be considered.
