Povidon suppositories can cure mycosis fungoides. Povidon suppositories are a proprietary Chinese medicine preparation used for dampness and heat stagnation caused by hypochondriasis, such as increased leucorrhea, yellow color, vaginal itching and mycosis fungoides, seen in the above symptoms. When using the medicine, wash the vulva, insert the pessary into the deep vagina and use the medicine for one course of treatment. At the end of the treatment, it is necessary to have a routine review of the leucorrhoea to know the treatment status of mycosis fungoides. Mycotic vaginitis is prone to recurrence. Even if the test is negative for mycobacterial spores after a course of treatment, it is recommended to consolidate the treatment for another course to prevent recurrence. During the treatment period, sexual intercourse should be prohibited to prevent cross-infection, and the underwear worn by the patient and the used utensils should be disinfected.
