Acquired labial sinechiae and hydrocolpos secondary to Stevens-Johnson syndrome.

Stevens-Johnson syndrome frequently affects the genitalia. Vaginal problems have been recognized in female patients; however, reports about the problem and its treatment are rare. Labial sinechiae have not yet been reported as sequelae of Stevens-Johnson syndrome. Amenorrhea, cyclical abdominal pain, and a hypogastric mass in girls affected by Stevens-Johnson syndrome could indicate acquired vaginal obstruction. Extensive labial sinechiae in such patients can cause dysuria, urinary tract infection, and sexual dysfunction. After a diagnosis of Stevens-Johnson syndrome in girls, it is prudent to schedule a prepubertal genital examination to diagnose genital disease preemptively and avoid obstructed menstruation and future sexual problems.
