Vulvovaginal Epithelioid Mesenchymal Neoplasm With "Deciduoid" Morphology: Report of a Novel Entity Frequently Associated With Inactivating Germline BAP1 Variants.
A wide variety of mesenchymal lesions arise in the vulvovaginal region, some relatively site-specific. We report 4 cases of a novel vulvovaginal mesenchymal lesion, which we term vulvovaginal epithelioid mesenchymal neoplasm with "deciduoid" morphology, reflecting the predominant morphologic feature of epithelioid cell...
