Extrapelvic endometriosis often presents as an atypical, painful abdominal mass often referred to the surgeon for diagnosis and treatment. The majority of extrapelvic endometriosis is found in surgical scars. We present a patient with an abdominal wall endometrioma that occurred in a laparoscopy trocar tract. To our knowledge, this is the first such case reported in the surgery or gynecology literature. With the increasing use of laparoscopy for gynecologic and general surgery procedures, this problem will likely become more common. The general surgeon should know how to diagnose and treat endometriomas arising in laparoscopic trocar tracts.
