Study objective: This case report is written to describe a new and unusual presentation of retroperitoneal cavernous lymphangioma.
Interventions: A large cystic abdominal mass was discovered during an examination under anesthesia to evaluate a vaginal discharge in a 6-year-old girl. The mass was diagnosed by computed tomography (CT) and removed via laparotomy with argon beam coagulation of smaller cystic lesions.
Results: Six months postoperatively, the patient had a negligible amount of vaginal discharge.
Conclusions: Cavernous lymphangioma should be considered as a rare cause of vaginal discharge in young females.
