Proposed novel nomenclature of vulvar smooth muscle tumors; a case of Smooth Muscle Tumor of Uncertain Malignant Potential (STUMP) of the vulva

Mathieu Viau et al. Gynecol Oncol Rep. .

Abstract

•Clinical experience with smooth muscle tumors of the vulva is limited.•Some tumors present ambiguous histological features concerning for malignancy.•These include infiltration, mitotic activity, size, atypia and tumor cell necrosis.•A case of smooth muscle tumor of the vulva with cellular atypia is presented.•"Smooth Muscle Tumor of Uncertain Malignant Potential" of the vulva is advocated.

Keywords: Cytologic atypia; Leiomyoma; Leiomyosarcoma; Smooth Muscle Tumor of Uncertain Malignant Potential; Smooth muscle tumor; Vulva.
