[Three cases of vaginal adenosis after topical 5-fluorouracil therapy for vaginal HPV-associated lesions]

Three cases of vaginal adenosis after topical 5-fluorouracil therapy for vaginal HPV-associated lesions are reported. Three patients with colposcopic, histologic and viral evidences for subclinical papillomavirus infection (in combination with low-grade vaginal intraepithelial neoplasia in of them) are treated with 5-FU. In follow-up control examinations persistent ulcerations were found without regression after applied therapy. By colposcopic and histologic examinations vaginal adenosis was proved without histories of intrautering DES exposure. After the destructive therapy the reported lesions were regressed without appearance of new lesions in follow-up control examinations. The application of 5-fluorouracil has to be used only in cases of recurrent vaginal warts and in cases of high-grade vaginal intraepithelial neoplasia with strict folow-up cytological and colposcopic control examinations.
