Mycosis fungoides is a common gynecological condition caused by Candida albicans infection. Mycosis vaginalis is a gynecological inflammation caused by a conditionally pathogenic bacterium that can be triggered when there is an increase in acidity in the vagina or a decrease in resistance in the organism. The common causes of mycosis are: long-term application of antibiotics, the unique vaginal environment during pregnancy, diabetes, lack of change or drying of underwear, cross-infection in public places such as hot springs, swimming, sharing towels, mixing socks and underwear after a family member has foot odor, more sexual partners, lack of hygiene during sex, lack of hygiene during menstruation and decreased resistance. Mycosis fungoides can usually be manifested as bean curd-like leucorrhea, itchy and painful vulva. Because the acidic environment and humidity are the pathogenic conditions of mycobacteria, the treatment can be done by using alkaline lotion such as sodium bicarbonate to rinse the vulva, and intravaginal clotrimazole pessary or dacrynic acid pessary, etc. During the treatment period, the underwear should be washed and disinfected to kill Candida. It is important to keep the vulva dry and clean to avoid the recurrence of mycosis vaginalis. In conclusion, mycosis vaginalis is a gynecological inflammation caused by Candida infection. It is common in pregnancy, diabetic patients, decreased resistance, long-term application of antibiotics, cross-infection or wearing socks with foot odor and underwear in the same wash. During the treatment and onset of the disease, you should not have intercourse, pay attention to a light diet and do not eat spicy and irritating hair products, etc.
