Adenosarcoma in a patient with vaginal endometriosis

Adenosarcoma in a patient with extraovarian endometriosis is a rare event and can be easily overlooked.

A woman with a history of endometriosis underwent multiple resections of a vaginal mass and medical treatment for presumed recurrent endometriosis. Eventually, a vaginal adenosarcoma was diagnosed.

The possibility of adenosarcoma should be considered if an enlarging mass occurs at the site of extraovarian endometriosis.
