Newborn With Vaginal Cyst

Abstract

A full-term newborn female was born with a 0.5 × 0.5 cm golden-colored fluid filled sac at the posterior aspect of the vaginal introitus. Physical examination revealed a patent introitus without additional cysts, a normal positioned urethral meatus, and a patent anus. Stool and voiding occurred in the first 24 hours of life. Hymenal cysts are rare and spontaneously resolve in the first few weeks of life without intervention. Physical examination is important to distinguish hymenal cysts from other interlabial cysts that may require treatment.
