Tubulosquamous Polyp of the Vagina: Misplaced Skene’s Glands Analogous to the Male Prostate

Abstract

Tubulosquamous polyp (TSP) of the vagina is a rare and benign lesion, best considered along the spectrum of lesions derived from Skene’s glands, the female counterpart of male prostatic glands. It is likely underdiagnosed and represents a challenging diagnosis if one is unfamiliar with this entity. We present an illustrative case of TSP occurring as an upper vaginal wall nodule of a 75-year-old woman, with characteristic morphology and broad immunophenotype. It should be suspected in postmenopausal women with a polyp that demonstrates biphasic squamous and glandular components, which show a prostatic immunophenotype.
