Adolescents With Labial Enlargement Misdiagnosed as Labial Masses on Imaging.

Abstract

Background: Literature describing radiologic imaging of the adolescent labia is lacking and may lead to misdiagnoses and unnecessary medical care. Cases: Two adolescent patients presented with sudden-onset unilateral labia minora enlargement and underwent multiple imaging modalities which identified a discrete mass. One patient was diagnosed with aphthous ulcers after a prolonged emergency department stay, and the other underwent an exam under anesthesia for mass removal and was found to have an elongated labia minora rolled into itself. Conclusion: Labia minora enlargement in adolescents can be significant and may be mistaken for a discrete mass on radiologic imaging given a lack of literature on expected findings. Clinical correlation and understanding of age-appropriate etiologies of noninfectious labial swelling is crucial to avoid unnecessary medical therapies and procedures.
