Paraurethral cyst in a newborn.

Paraurethral cysts are rare and occur with obstruction of the Skene duct. In this case, we aimed to present a paraurethral cyst in a baby girl. A 4-day-old newborn was consulted for pediatric urology because of an interlabial mass. In genital examination, a noninvasive mass measuring 2 × 1.5 cm was observed in the interlabial region, and the introitus was completely closed. Ultrasonography showed a cystic lesion localized on the right side of the urethra with a smoothly contoured, thin-walled, hypoechoic structure. The patient underwent puncture under sterile conditions. The content of the mass was mucoid and clear fluid. Paraurethral cysts are often asymptomatic and benign. There is no definitive consensus on treatment.
