Scar endometriosis is an uncommon form of endometriosis in which tissue similar to the lining of the uterus develops within or around a previous surgical scar. It most commonly occurs after procedures involving the uterus or pelvis, particularly Caesarean section, but may also develop after other gynaecological or laparoscopic procedures.
A typical feature is a painful lump, swelling or tenderness near a previous surgical scar that becomes more noticeable or painful around menstruation. Because scar endometriosis can resemble other conditions such as a hernia, cyst or abscess, proper evaluation is important.
At Divine Care, Dr. Gursimran Kaur provides comprehensive gynaecological care with expertise in minimally invasive and laparoscopic gynaecological surgery, robotic surgery, infertility and reproductive medicine. Patients with a suspected scar-related endometriosis lesion can be evaluated according to their symptoms, medical history and clinical findings.
Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus. When such tissue develops within or around a previous surgical scar, it is commonly referred to as scar endometriosis or abdominal wall endometriosis.
The condition can develop months or even years after a previous operation. The endometriosis tissue can respond to hormonal changes during the menstrual cycle, which may cause pain, swelling or tenderness around the affected area.
Scar endometriosis is usually localized to the abdominal wall or another previous surgical site, although some women may also have endometriosis elsewhere in the pelvis.
Scar endometriosis can develop at or near different types of previous surgical or procedural scars. Common locations include:
The location, size and depth of the lesion are important when deciding which investigations and treatment approach may be appropriate.
The symptoms of scar endometriosis often follow a cyclical pattern and may become more noticeable before or during menstruation.
Common symptoms may include:
A lump near a surgical scar does not necessarily mean endometriosis. Hernia, infection, cysts, scar tissue and other conditions can produce similar findings. Evaluation is therefore important before deciding on treatment.
Scar endometriosis should be considered when a woman develops a new lump, swelling or pain near a previous surgical scar, particularly when the symptoms repeatedly become worse around menstruation.
Medical evaluation may be appropriate if you notice:
Diagnosis begins with a detailed medical and surgical history, including the type of previous operation, location of the scar and relationship between symptoms and the menstrual cycle.
Depending on the clinical findings, evaluation may include:
Not every patient requires every investigation. The appropriate evaluation depends on the clinical examination, symptoms and suspected extent of the lesion.
Scar endometriosis is generally a localized condition, but it can cause significant pain and discomfort, particularly when symptoms repeatedly occur with the menstrual cycle.
If left untreated, a scar endometriosis lesion may gradually increase in size and become increasingly painful or tender. It can also be difficult to distinguish from other abdominal wall conditions without appropriate evaluation.
Malignant transformation of endometriosis is considered very uncommon. Any new, enlarging or changing mass should, however, be properly assessed rather than assumed to be endometriosis.
Treatment depends on the size and location of the lesion, severity of symptoms, depth of involvement, previous treatment and the patient's overall health and reproductive plans.
Depending on the individual situation, management may include:
When surgical treatment is appropriate, the goal is to remove the affected endometriosis tissue completely while taking into account the surrounding abdominal wall structures.
The exact surgical technique depends on the size, depth and location of the lesion. Deeper lesions may require more extensive removal of affected tissue and appropriate repair of the abdominal wall.
Dr. Gursimran Kaur has specialized training in minimally invasive and laparoscopic gynaecological surgery, along with certified training in robotic surgery and advanced gynaecological procedures. Her approach to surgical care is based on appropriate evaluation and individualized treatment planning.
The choice of procedure should be made after assessing the lesion and discussing the expected benefits, risks and alternatives with the patient.
One of the more recognized presentations of scar endometriosis is a painful lump developing near a previous Caesarean section scar.
The lump may not appear immediately after the operation. Symptoms can develop months or years later, which can make the connection with the previous surgery less obvious.
A lump that repeatedly becomes painful, swollen or tender during periods should therefore be evaluated rather than assumed to be ordinary scar tissue.
Scar endometriosis itself is primarily an abdominal wall or surgical-site condition. However, some women with scar endometriosis may also have endometriosis affecting pelvic organs, which can have implications for fertility.
Fertility assessment may therefore be considered when a woman has difficulty conceiving or has symptoms suggesting endometriosis elsewhere in the pelvis.

Scar endometriosis may sometimes occur together with other forms of endometriosis or other gynaecological conditions. Proper evaluation is therefore important when symptoms extend beyond the scar itself.
Dr. Gursimran Kaur's clinical profile includes minimally invasive, laparoscopic and robotic gynaecological surgery, infertility and reproductive medicine, hysteroscopy and management of complex gynaecological conditions. :contentReference[oaicite:3]{index=3}
Treatment is planned according to the patient's individual findings rather than assuming that every painful surgical scar represents endometriosis.
Consider a gynaecological consultation if you notice:
Scar endometriosis can be painful and may cause considerable concern, particularly when a lump develops years after surgery. Because several other conditions can produce similar symptoms, accurate assessment is important before treatment is selected.
At Divine Care, Dr. Gursimran Kaur provides patient-focused gynaecological care with an emphasis on appropriate diagnosis, minimally invasive surgical expertise, reproductive health and individualized treatment planning.
Every patient is assessed individually, and treatment recommendations are based on the clinical findings, symptoms, lesion characteristics and the patient's specific needs.
If a lump, swelling or pain near a previous Caesarean or gynaecological surgical scar becomes worse around periods, seek an appropriate gynaecological evaluation.
