Vaginal dermoid cyst

Published:March 10, 2021DOI:https://doi.org/10.1016/j.ajog.2021.03.010
      A 27-year-old gravida 1 para 1 presented with a painless, left anterolateral vaginal wall mass, measuring 10 cm in diameter, which had been slowly growing over several years. Pelvic magnetic resonance images were concerning for a large Gartner’s duct cyst based on the location and appearance of the mass (Figure 1). After an uncomplicated vaginal cystectomy, the mass grossly revealed spillage of sebaceous material and the presence of hair (Figure 2). Further pathohistologic evaluation confirmed the diagnosis of a rare vaginal dermoid cyst (mature cystic teratoma) given the presence of squamous epithelium, sebaceous glands, hair follicles, capillaries, and adipose tissue, representing all 3 embryonic layers (Figures 3 and 4). Vaginal dermoid cysts are extremely rare, with (to the best of our knowledge) fewer than 10 cases documented in the literature. This patient subsequently healed well with no postoperative complications immediately or at her 2-week follow-up appointment.

      The cyst measured 8×5×5 cm and on opening revealed both hair and sebaceous material consistent with a dermoid cyst.
