Microscopy typically shows absent vaginal flora, numerous polymorphs and immature parabasal cells with no mature epithelia. The pathogenesis of DIV is currently unknown but may involve tissue kallikrein-related peptidases which are regulated by sex hormones and corticosteroids. Case-1: 35-year-old trans-man on testosterone for 18-months presenting with yellow vaginal discharge, vestibular pain and dyspareunia. Examination revealed vaginal inflammation and mucopurulent discharge. Microscopy was typical of DIV. He was treated with intravaginal clindamycin reporting a good response. Case-2: 26-year-old trans-man on testosterone for 7-years presenting with vaginal discharge, dyspareunia and post-coital bleeding. Examination revealed inflamed friable vaginal mucosa. Microscopy findings were typical of DIV and he started treatment with intravaginal clindamycin (partial-response) and switched to intravaginal prednisolone. Case 3: 20-year-old trans-man with vaginal discharge and post-coital bleeding who started testosterone 6-months earlier. Examination and microscopy findings were typical of DIV. He commenced treatment with intravaginal clindamycin (partial-response) and switched to intravaginal prednisolone. Case 4: 19-year-old trans-man on testosterone for 9-months presenting with vaginal pain and bleeding. Examination and microscopy were typical of DIV. He started treatment with intravaginal clindamycin (partial-response) and switched to intravaginal prednisolone. Discussion We present four cases of DIV in trans-men possibly associated with androgens responding to intravaginal clindamycin and steroids. As well as causing significant morbidity DIV may increase transmission of sexually-transmitted-infections in trans-men: we need to understand more about its aetiology, management and long term outcomes.
