title: Efferent ductule cyst of tunica albuginea.
abstract: A cyst of the tunica albuginea is reported. For this cyst, anatomic arguments favor an efferent ductule origin over an origin from mesothelial rests. This cyst is an important benign differential diagnosis of a testicular mass and requires only local excision.
