[Abnormalities of external and internal genitalia].
The gynecologic examination of the female genitalia of children and young adults belongs in the hands of specialists and should be performed in the appropriate environment. The most important task of such an examination is the distinction between true developmental anomalies and anatomical findings mimicking such anomalies. Even newborn females can be successfully examined without any large effort expenditure. In most cases, the external inspection of the vestibule is enough to reach a diagnosis. In other case scenarios, vaginoscopy and gynecological speculum examination may be necessary. Additional imaging studies include abdominal sonography and magnetic resonance imaging. Normal variations of a child's hymenal membrane, fusion of the labia minora, hymenal polyps and hypertrophy of the preputium of the clitoris are the entities most likely to be mistaken for real developmental malformations. The most important asymptomatic developmental anomaly of the vagina and the uterus is the Mayer-Rokitansky-Kuster-Hauser syndrome (uterine and vaginal agenesis). Developmental malformations, such as hymenal atresia, vaginal septum formation and Millerian anomalies in general, tend to be symptomatic, presenting with hematometra, hematocolpos or dysmenorrhea. The treatment of genital developmental anomalies is generally not difficult but requires the appropriate clinical and surgical expertise.
