Rare (uro-)genital pathologies in young girls mimicking sexual abuse

Abstract

AbstractExaminations of young children for suspicions of sexual abuse are challenging for the involved medical specialists because the consequences of the interpretation of the findings can be severe and dramatic. A broad knowledge of differential diagnoses including rare pathologies like urethral prolapse and failure of the midline fusion of the perineum, known as perineal groove, is essential in order to avoid unnecessary diagnostics and treatment, prejudgment, and to reduce patient family’s anxiety. We report two independent cases of girls aged 7 months and 5 years suffering from these rare pathologies, one presenting with painless lower genital tract bleeding, the other showing a lesion of the perineum as random finding during a neuropediatrician’s consultation. In both cases, the pathologies were initially misdiagnosed as injuries due to sexual assault, and judicial investigation procedures were initiated. In this paper, the characteristic symptoms and morphology of urethral prolapse and perineal groove are presented to enhance the awareness of these pathologies among forensic experts and help to establish the correct diagnosis.
