title: New phenotype of accessory scrotum with perineal lipoblastoma: coexistence of midperineal and lateral accessory scrotums.
abstract: We present the extremely rare phenotype of an accessory scrotum with an associated lipoblastoma. There was a coexistence of midperineal and lateral types. To our knowledge, this phenotype has never been reported. The lipoblastoma, which arose in the perineum, divided the moving labioscrotal swelling into three parts during early fetal life. This resulted in the specific anomaly in this patient.
