Skene Duct Cyst
Introduction
Skene duct cysts develop adjacent to the distal urethra, sometimes causing perineal discharge, dyspareunia, or abscess formation. Skene glands (periurethral or paraurethral glands) are located adjacent to the distal urethra. At the center of this image is the vagina, a canal composed of smooth muscle. The small opening directly above it is the urethra, which is the opening from the bladder. Below the vagina is the anus. Above the urethra is the clitoris, a body of erectile tissue that is homologous to the penis. The vagina is surrounded by the labia minora, which are surrounded by the labia majora. The pubic bone is at top. The purple tissue is a continuation of the clitoris, the crus of clitoris. The bulb of the vestibule (blue) also consists of erectile tissue. Below the bulb is a Bartholin gland, which secretes mucus to lubricate the vagina. BO VEISLAND/SCIENCE PHOTO LIBRARY Skene duct cysts form if the duct is obstructed, usually because the gland is infected. They occur mainly in adults. Cysts may become infected, leading to recurrent urinary tract infections (UTIs) and abscesses. Rarely, Skene duct cysts (if large enough) obstruct the urethra. Most Skene duct cysts are<1 cm and asymptomatic. Some are larger and cause dyspareunia. The first symptoms may be similar to those of UTIs (eg, dysuria). Abscesses are painful, swollen, tender, and erythematous but usually do not cause fever.
