Abstract

BACKGROUND: Endometriosis is a disorder in which an ectopic endometrial tissue grows outside the uterine cavity. The ectopic endometrium embedded in the subcutaneous fatty layer and the muscles of abdominal wall is called as abdominal wall endometriosis (AWE). AWE is a rare condition; however, it is usually known to develop along with previous surgical scars. Caesarean section and hysterectomy are considered to be commonly associated with the development of AWE. METHODS: We evaluated the data of the patients who underwent AWE surgery between March 2009 and March 2014. RESULTS: The mean age of the patients was 32.5 years. We found a previous history of caesarean section in all of the patients. The most frequent symptoms of the patients were abdominal mass sensation and abdominal pain. Invasion of endometriosis to fat layer, fascia, muscular layer, and peritoneum was recorded. Three masses were located within the scar regions. CONCLUSIONS: We can conclude that there is a high prevalence of caesarean sections among the women with AWE.

TL;DR

In a five-year single-center series of 30 patients with histologically confirmed abdominal wall endometriosis (AWE), all had a prior caesarean section and all presented with a mass. The authors conclude that AWE is strongly associated with caesarean section and may become more frequent as caesarean section rates rise.

Key findings

  • The mean age was 32.5 ± 8.24 years (range 23–67). All 30 patients had a previous caesarean section: 11 (36.6%) had one, 14 (46.7%) had two, and 5 (16.7%) had three.
  • All patients had a mass; 24 (80%) had pain, including 14 (46.7%) with cyclic pain and 10 (33.3%) with noncyclic pain. Mean symptom duration was 12.7 ± 10.44 months (range 3–45), and mean time from previous surgery to AWE diagnosis was 30.5 ± 12.65 months.
  • Ultrasonography was used in 28 patients (93.3%); 27 (90%) had a single mass and 3 (10%) had two masses. Initial diagnosis was AWE in 19 patients (63.3%), while 11 (36.7%) were initially misdiagnosed.
  • Mass location was in or under the previous surgical scar in 21 patients (70%), including 3 (10%) within the scar. Mean mass diameter was 2.59 ± 1.21 cm (range 1–6 cm). One patient had a recurrent mass after six months; no malignancy was reported.

Methods

  • The study evaluated data from patients who underwent surgery for AWE between March 2009 and March 2014 at Shahid Beheshti Hospital, with institutional review board approval from Kashan University of Medical Sciences.
  • Data collected included age, parity, related past medical history, chief complaint, exact site of AWE, and postoperative information. Histological confirmation required at least two of three features: endometrial stroma, endometrial-like glands, and hemosiderin pigment.
  • Thirty patients with histopathologically confirmed AWE were included; the analysis reports descriptive frequencies, percentages, ranges, and means.

Limitations

  • The paper states that fine-needle aspiration cytology was not performed in this study.
  • No formal limitations section is provided; evident from the text, this is a single-center case series of 30 patients with no control or comparison group.
  • Follow-up duration is not specified beyond one recurrence detected at six months, and no malignancy was reported, so long-term outcomes and malignant transformation risk cannot be assessed from these data.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Parity range differs between Results and Table 1

    Minor

    The Results state that parity ranged from one to four, while Table 1 gives a range of zero to four.

  • Four asymptomatic patients conflict with universal presenting mass

    Minor

    The Results say every patient had a mass as a presenting symptom, but also say four patients had no symptoms and were diagnosed during caesarean sections.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
