Endosalpingiosis is, like endometriosis, the presence of cystic masses outside of the salpinx which contains fallopian tube epithelium. Endosalpingiosis can be seen on the surface of ovaries, tubal serosa, uterine serosa, myometrium, and also in the bladder. The main clinical features of endosalpingiosis are pelvic pain, adnexal mass which mimics cancer, and urinary symptoms. Herein, we present a surgical video of endosalpingiosis in a woman with endometriosis and a dermoid cyst.
