[Pseudosarcomatous variant of a genital fibroepithelial stromal polyp in a pregnancy].

Fibroepithelial stromal polyps are benign neoplasms of the lower genital tract occurring mostly in young to middle-aged women in their reproductive years. Clinically they appear as tender, skin-colored, sack-like tumors and usually have a bland microscopic appearance. Sometimes, especially during pregnancy or with hormone therapy, a worrisome hypercellular and pseudosarcomatous pattern can be seen in the dermis. Awareness of this neoplasm with a possibly high degree of atypia is of crucial importance in order to avoid unnecessary radical surgery.
