When fibromas are located on the vulva, they often affect the labia majora and less frequently in the labia minora, clitoris, vestibule, and posterior commissure [2]. In our case, it affected the labia majora. Vulvar fibromas are usually small but can become pedunculated as they grow larger [7]. There are rare reports in the literature of giant fibromas developing without seeking medical help [8]. However, our patient took only four months before asking for medical help because her tumor developed very quickly, even though fibromas are characterized by slow expansion and growth [9]. But in our case, its size increased remarkably over 4 months until it became a pedunculate oval mass with (15*7*17cm) size, meanwhile, Najam et al, reported that their case took 7 years to get(15*8*18cm) [9], as Isoda et al, mentioned that his case took 5 years to be only 7 cm sized [1]. Başbuğ et al, reported that one of the largest vulvar fibromas measured 550 g, and it took 2 years to reach this weight [3], but in our case, the tumor reached 1.7 Kg in only four months.
