EP26.15: Labial fusion: a rare cause of hematocolpos in reproductive age normally menstruating woman

Labial fusion typically impacts prepubertal girls and postmenopausal women, but it can rarely occur during the reproductive years without predisposing factors such as vulvar infections, dermatitis, trauma, female circumcision, or lichen sclerosis. We present the case of a 26-year-old female with Down syndrome who experienced urinary retention and abdominal pain. Obtaining a comprehensive medical history was challenging, but her parents reported regular menstrual cycles. The patient refused physical examination. A urine culture revealed Klebsiella sensitive to ciprofloxacin. Ultrasound identified a large 8cm hematocolpos. To rule out congenital malformations, an MRI was conducted, revealing a triangular-shaped fluid collection draining the urethra in the vagina and above the major and minor labia (see figures 1,2). Under general anesthesia, a physical examination unveiled complete labial fusion, which was surgically corrected through blunt dissection. Simultaneously, cystoscopy returned normal results. The patient was discharged on the same day, and her postoperative recovery was uneventful.
