The tumor arose from the right lateral vaginal fornix and it was a large, well-circumscribed, pedunculated mass (Figure 1(a)). The patient was submitted to a complete surgical excision of the mass during the 13th week of gestation (Figures 1(b)-1(d)), which revealed its solid nature and the extension to the right paravaginal tissues.
