Yellowish-green purulent leucorrhea is most often seen in trichomoniasis, which is caused by Trichomonas vaginalis and is a common vaginal inflammatory disease that is characterized by increased vaginal discharge, which may be accompanied by painful vulvar itching and a foul odor. The main symptoms are increased vaginal discharge, painful itching, and foul odor. The gynecological examination and vaginal discharge examination should be done. The internal examination shows congestion of the vaginal mucosa and in severe cases, scattered bleeding spots and bleeding spots on the cervix, resulting in a strawberry-like cervix, which are characteristic changes of trichomoniasis. Treatment is either systemic or topical with metronidazole, with systemic medication being more effective. Since the infection is transmitted through sexual intercourse, it is important to treat the sexual partner as well. During the treatment period, it is important to boil and disinfect your clothing, pay attention to personal hygiene, avoid going to public baths and swimming pools, and pay attention to intercourse hygiene.
