BACKGROUND: The relatively site-specific mesenchymal lesions of the vulvovaginal region can exhibit superficially overlapping histological features and can be diagnostically challenging. Fibroepithelial stromal polyp is generally an easily recognizable entity, but certain cases cause differential diagnostic problems. CASE: We present a case of a 16-year-old girl with a 10-cm polypoid lesion localized to the left labium. The patient has therapy resistant congenital lymphedema localized to the left arm and leg. The labial lesion was resected and recurred after 12 months and 6 years following the initial treatment. Histologically, it exhibited characteristics of a fibroepithelial stromal polyp with scattered bizarre multinucleated giant cells and ectatic tortuous lymphatic spaces. CONCLUSION: This vulvar lesion represents a unique example of giant fibroepithelial stromal polyp developed in association with Nonne-Milroy-Meiges syndrome.
