Vaginal tumors, whether benign or malignant, are
rare. They include fibroepithelial polyps (FEPs), which are benign lesions
originating in mesenchymal cells, comprised of a core of connective tissue
covered by squamous epithelium. They are usually small and asymptomatic. When
symptomatic or very large, they may cause bleeding, genital discomfort or the
presence of a bulge in the vagina. In the last case, they may be mistaken for a
genital prolapse. Although their physiopathology is still not clearly
understood, the presence of hormonal receptors and the occurrence of FEPs
during the use of hormone therapy or pregnancy suggest that changes in the
stroma of these lesions may be induced by hormones. We report on the case of a
patient who presented with a vaginal bulge and was referred to the
urogynecology outpatient ward with a diagnosis of genital prolapse, which had actually a large fibroepithelial polyp on the posterior vaginal
wall.
