Sacrococcygeal Teratoma Presenting with Vaginal Discharge and Polyp in an Infant

Abstract Background Sacrococcygeal teratoma accounts for the most common solid tumor in neonates. Because of improved technology, 50%-70% of cases can be diagnosed antenatally during routine ultrasound screenings. If not diagnosed antenatally, clinical findings at birth are distinct in most cases including a palpable or visible mass. Case We report an unusual case of a 1-year-old girl who presented with persistent vaginal discharge leading to diagnosis of a mucosal polypoid lesion of the vagina, ultimately revealing a hidden sacrococcygeal teratoma. Summary and Conclusion We suggest thorough investigation of all infants who present with purulent discharge and recurrent vaginal mass; sacrococcygeal teratoma should routinely be considered as a differential diagnosis.
