Vulvar ulcers may be related to trauma, syphilis, genital herpes, vulvar tumors and other factors. Patients with recurrent vulvar ulcers need to alleviate the condition through general treatment, medication and surgery according to the cause of their illness. 1. Trauma: For vulvar ulcers caused by trauma, patients need to keep the vulva clean and dry, and can use iodine povidone to disinfect the affected area, or apply mupirocin ointment for anti-infection treatment. 2. Syphilis: For patients with syphilis-induced vulvar ulcers, penicillin can be used as prescribed by the doctor, and erythromycin and fusidic acid ointment can be applied to the ulcerated surface. Patients need to use iodine to disinfect the skin of the vulva at regular intervals, keep the local skin clean and dry, and prohibit coitus during the treatment period. 3. Genital herpes: For vulvar ulcers caused by genital herpes, patients can take acyclovir, vasiclovir, famciclovir and other medications as prescribed by the doctor for systemic treatment. Patients can also use physiological sodium chloride solution for cleaning, or wet application of 3% boric acid solution, but also can be applied locally acyclovir cream or 1% Penciclovir cream for treatment, to alleviate the recurrence of vulvar ulcers. 4. Vulvar tumor: For the recurrence of vulvar ulcers caused by vulvar tumors, patients can be treated with surgery and then supplemented with chemotherapy and radiotherapy according to their own conditions. It is recommended that patients strictly follow the doctor’s instructions to use medication, do not change the dose of drugs without authorization or abuse drugs privately, pay attention to monitoring the condition in life, and follow the doctor’s instructions for regular review.
