Endometriosis is characterized by the presence of endometrial glands and stroma outside
the uterine cavity. The occurrence of endometriosis in the anterior abdominal wall
is often associated with previous cesarean section, once the spread of endometrial
cells during the surgical procedure is a biologically fact possible. A 43-year-old
patient, with cesarean section history and pelvic endometriosis diagnosed for over
10 years, presented with progressive abdominal pain. Tests showed cystic image with
1.6 cm of diameter and debris, located in mid-lower portion of the rectus abdominis
left, suggesting abdominal wall endometriosis. This abdominal wall lesion was not
identifiable in the clinical examination (impalpable), which is why we opted for the
use of preoperative marking technique with radioisotope called Radioguided Occult
Lesion Localization (ROLL™). The use of ROLL™ in this case allowed rapid surgical identification of endometriotic lesion and its
complete excision.
