Gynecological inflammatory diseases can be divided into several specific types of vaginal inflammation depending on their pathogenic microorganisms. Among them, tofu-like discharge can suggest the possibility of mycotic vaginitis. Mycobacterium is a conditionally pathogenic bacteria in the human body. It is called a conditional pathogen because mycobacteria are present in the normal vaginal flora of the vagina. However, in general, mycobacteria in the resident vaginal flora are not pathogenic. It is only when the body’s resistance is weakened or when antibiotics are used for a long time that mycobacteria can multiply in a short period of time, leading to the formation of vaginal mycobacterial inflammation. When there is vaginal mycosis, due to the influence of mycobacteria, can cause vaginal tofu-like discharge, accompanied by symptoms of vulvovaginal itching. Therefore, when a patient has a tofu slag-like discharge, it is indicative of mycosis fungoides and requires prompt medical attention and a routine test of the discharge to clarify the diagnosis. Once the diagnosis of mycosis vaginalis is confirmed, there is no need to be overly alarmed, as most patients will improve with topical vaginal medication.
