Abstract

Abdominal wall endometriosis is atypical localization of the extra-pelvic endometriosis with non-specific symptoms and is difficult for diagnosis. Cesarean scar endometriosis (CSE) is the most common type of abdominal wall endometriosis, which usually develops after obstetric operations. We report a case of a 33-year-old woman who had two previous cesarean sections presented with a mass in the subcutaneous tissue of the abdominal wall, approximately 4 cm superior to the Pfannenstiel incision, 5 years after her second lower segment caesarean section. The classic clinical presentation, imaging findings on ultrasonography and computed tomography are analyzed. Treatment with local surgical excision of the mass is discussed. The diagnosis was confirmed with histopathological analysis of the surgical sample. When it comes to the limited painful lesion in the subcutaneous tissue at the cesarean scar, with a pain intensifying during menstruation, the physician should consider cesarean scar endometriosis in women of reproductive age with a history of cesarean section.

TL;DR

This case report describes a 33-year-old woman with cesarean scar endometriosis presenting 5 years after her second cesarean section as a painful abdominal wall mass that worsened during menstruation. Diagnosis was confirmed by histopathology after wide surgical excision, and she was discharged 4 days postoperatively in good condition.

Key findings

  • A 33-year-old woman with two previous cesarean sections presented with a painful subcutaneous mass at the cesarean scar; symptoms began 4 years after her second lower-segment cesarean section and worsened cyclically with menses.
  • Imaging showed a heterogeneous hypoechoic subcutaneous right paramedian mass measuring 5.7×5.3 cm on ultrasound and a 7.3×4.5 cm solid soft-tissue lesion on CT; CA-125 was elevated at 204 U/mL (reference 0–35 U/mL), while CA 19-9 and carcinoembryonic antigen were normal.
  • Wide surgical excision removed a firm mass about 5×7 cm infiltrating the rectus sheath and right rectus abdominis muscle to a depth of about 2 cm; histopathology showed endometrial glands and stroma involving fibro-adipose and muscular tissue with hemosiderin pigment.
  • The paper notes cesarean scar endometriosis is the most common abdominal wall endometriosis, with an estimated incidence of 0.03–0.4%, and that abdominal wall is the most common site of extra-pelvic endometriosis (4%).

Methods

  • Single case report of one patient managed at a gynecology department.
  • Data included obstetric history, clinical examination, routine laboratory tests, tumor markers, abdominal ultrasound, transvaginal ultrasonography, and contrast-enhanced CT.
  • Main intervention and analysis were surgical excision of the abdominal wall mass and histopathological examination of the specimen.

Limitations

  • The paper does not state limitations.
  • Evident from the text: this is a single case report, so findings are not generalizable and no comparison group or systematic follow-up is reported.
  • Evident from the text: follow-up is limited to discharge 4 days after surgery in good condition; recurrence or long-term outcomes are not reported.

    Ultrasound of the anterior abdominal wall showed a heterogeneous predominantly hypoechoic subcutaneous right paramedian mass attached to the rectus abdominis muscle with internal scattered hyperechoic partition and speculated margins infiltrating the surrounding tissue measuring 5.7x5.3cm located in the subcutaneous plane of the right upper abdominal quadrant at the site of the pain.

The paper does not classify abdominal wall endometriosis as a primary form or rank it among the rarest primary forms; it instead calls the abdominal wall the most common site of extra-pelvic endometriosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
