It may be a local nodular cyst caused by inflammation or allergy, or it may be a mass, usually seen in vestibular gland cysts, submucosal fibroids and other diseases, which need to be treated after clarifying the cause. 1. Vestibular gland cysts: When inflammation of the vulva or vagina is not given anti-inflammatory treatment in time, it causes blockage of the vestibular gland ducts, which accumulate in the cystic cavity and form cysts. The cysts are hard and can cause severe pain and even localized suppuration when infected. If a hard mass is found clinically and is relatively small, it can be left untreated for the time being and attention should be paid to keeping the vulva clean in daily life. If the cyst is large, surgery is recommended. 2. submucosal fibroids: the fibroids are large in size and prolapse downward into the vagina or even to the vaginal opening, depending on the situation, the fibroids can be removed or hysterectomized. 3. vaginal masses: benign and malignant vaginal tumors located near the vaginal opening, such as vulvar papilloma, depending on the pathological stage and the size of the tumor, the surgery can be removed. 4. other: e.g. vulvovaginitis, vulvar eczema, folliculitis, etc. can also be treated. 4. Other: for example, vulvodynia, vulvar eczema, folliculitis, etc., there can also be hard lumps in the vaginal opening, which can be treated with appropriate medication after consultation.
