Mycosis fungoides, medically called vulvovaginal pseudomycosis, is an inflammation of the vulva and vagina caused by Pseudomonas albicans. Pseudomonas albicans is a fungus, so treatment of mycosis vaginalis is mainly with antifungal drugs, mainly azoles, such as clotrimazole, miconazole, fluconazole, etc. For mild symptoms or first attacks, topical medication is the main treatment, i.e. medication is placed deep in the vagina. For unmarried women and patients for whom topical medication is not appropriate, oral fluconazole, etc. can be given. For patients with severe or recurrent symptoms, the same medications and usage are used as described above, but a longer course of medication is required. The efficacy of the medication needs to be reviewed regularly during the period of administration, and those with poor results need to change the medication. It is also necessary to actively search for the cause of the disease and prevent it in advance. Pregnant patients should be treated with small doses, long courses of topical medication, and oral azole antifungal drugs are prohibited. Patients with mycosis fungoides commonly use azole antifungal drugs. In addition to the application of drugs, patients need to stop using broad-spectrum antibiotics and estrogens; actively treat diabetes in diabetic patients; wear cotton and loose underwear; pay attention to personal and sexual hygiene; keep the vulva clean and dry; and change and disinfect intimate clothing regularly.
