● Benign ovarian cysts arising from mesonephric (wolffian) or paramesonephric (mullerian) remnants
● Common in ovarian hilus
● With serous borderline tumor (Histopathology 1983;7:601)
● Excise if diagnosis is in question, the cyst persists, or patient is symptomatic (Semin Pediatr Surg 2005;14:78)
● Laparoscopy is favored treatment
● Goal is to spare functional ovary as much as technically possible
● Simple cysts are fenestrated
● Complex or functional cysts are excised with preservation of remaining ovary
● Cysts of mesonephric (wolffian) origin: cuboidal or low columnar, nonciliated epithelium, on well developed basement membrane; have smooth muscle coat
● Cysts of paramesonephric (mullerian) origin: resemble fallopian tube; taller, often ciliated epithelium with larger nuclei, inconspicuous basement membrane; have smooth muscle coat
