Paraurethral Cyst in Newborn

A girl was born at term. Four days old, an interlabial cyst appeared, located anterior to the vaginal introitus. The urethral meatus was normally positioned and there was no voiding difficulty. Interlabial cysts in newborn girls are rare and may have different origins. This girl had a so-called paraurethral cyst, which is often possible to recognize by clinical examination. This sort of cyst is generally completely asymptomatic and has a high rate of spontaneous involution. Without any treatment, the cyst had disappeared at examination two months later.
