An overlooked diagnosis in an adolescent who was admitted with abdominal pain: Imperforate hymen

Abstract

Imperforate hymen is a rare anomaly of the female genital system. Patients are usually admitted with an absence of menarche and accompanying cyclic abdominal pain, despite the presence of secondary sex characteristics during puberty. Diagnosis is usually delayed; however, keeping this condition in mind may facilitate earlier diagnosis. The observation of purplish swelling at the vestibular opening site on genital examination may guide diagnosis.
