Abdominal Wall Endometrioma after Laparoscopic Operation of Uterine Endometriosis

Cyclically bleeding trocar-site endometrioma without known history of endometriosis: case report and literature review

Endometriosis occurrence at a laparoscopic trocar-site incision is extremely rare with only 30 previous cases published. We present a 43-year-old female with surgical history of two cesarean sections and a laparoscopic Roux-en-Y gastric bypass who presented with history of cyclical bleeding from an umbilical mass coinciding with her menstrual cycle. Ultrasound demonstrated a complex solid and cystic lesion measuring 2.5 x 1.4 x 1.4 cm. This umbilical mass was surgically resected and gross examination perioperatively demonstrated dark-colored cystic implants consistent with endometrioma. Pathology confirmed the suspected diagnosis of endometriosis. There are several noteworthy characteristics in this unique case of laparoscopic trocar-site endometrioma. Umbilical bleeding is an unusual presenting symptom that has not been previously reported. This endometrioma occurred at the umbilical laparoscopic site rather than her Pfannenstiel incision. Laparoscopic Roux-en-Y gastric bypass has not been previously associated with trocar-site endometrioma. Of note, this patient had no known history of endometriosis.

Rectus Abdominis Endometrioma after Caesarean Section

Isolated rectus abdominis muscle endometriosis is very uncommon with less than 20 case reports being published to date since its first description in 1984 by Amato and Levitt. We report another case of isolated rectus abdominis endometriosis in a 37-year-old patient with a previous caesarian section. We also discuss the diagnostic and treatment particularities in these patients. In our case, the treatment was only surgical and currently the patient is disease-free during the 24-month follow-up.
