Prenatal sonographic detection of congenital perineal lipoma in a newborn girl / 대한산부인과학회지

ABSTRACT

We report on a newborn girl presenting with a 2.0x1.5 cm sized pinkish, doughy lump arising between right labia majora and anus. We performed antenatal sonogram at 33 and 36th weeks gestation. A polypoid mass of 0.8x1.0 cm sized in size was noted on ultrasonography. After birth, we observed a skin-covered protruding mass not to detect other anatomic anomalies-spinal anomalies, anorectal malformations, etc. After 3 months, excision of the perineal mass was done at the Department of Pediatric Surgery of our hospital. Mature fat cells were noted on histopathological exam. To our knowledge, there are few studies in the English literatures about congenital perineal lipoma without combined structural anomalies.
