case_images: A gynecologic examination and cervical biopsy were performed, which showed positive acetic acid and negative iodine staining tests (Figure 2A, D). A histopathologic examination of the biopsy indicated grade I cervical intraepithelial neoplasia (Figure 2G). To better evaluate the patient's cervical condition and due to the remaining HPV type 6 positivity, colposcopy and biopsy were performed, which revealed a mostly smooth cervix with a cluster of acrocyanotic warts in the 3-5 o'clock position (Figure 2B, E). Biopsy of the deeper cervical canal area was performed, indicating persistent grade I cervical intraepithelial neoplasia (Figure 2H).
