Pre-term cesarean delivery was performed due to breech labor and perinatal death. The autopsy confirmed hydrometrocolpos secondary to vaginal atresia and imperforate hymen, associated with cryptophthalmos, syndactyly, nasal and pinna malformations, confirming the diagnosis of Fraser syndrome.Fraser syndrome is usually a postnatal diagnosis. The association with genital abnormalities explains the finding of hydrometrocolpos, which could be considered a diagnostic criterion for this syndrome.
