Labial fusion (LF) is a rare condition defined by a complete or a partial adhesion of the labia minora in the midline. It has been reported at different stages of life and is divided into primary and secondary LF [1]. Primary LF usually occurs in young girls before the age of 2 (incidence ≈ 1% [2]) and at any age before puberty [1].

Secondary LF occurs after puberty. It is extremely rare, both in the reproductive and postmenopausal population, with only a few documented cases in the literature [1, 3]. It is usually caused by estrogen deficiency, particularly in nonsexually active postmenopausal women affected by advanced lichen sclerosus et atrophicus [1].

Complete LF can result in a very poor urinary flow and a reflux of urine filling the vagina causing urocolpos, dribbling, and a predisposition to ascending infections [1].
