Scar endometriosis: a rare entity

Kanika Dhiman, Sara Guleria, Himang Jharaik


Endometriosis is described as the presence of functioning endometrial tissue outside the uterine cavity. Scar endometriosis is a rare disease with an incidence of 0.8% and is difficult to diagnose. It can occur after any surgery which involves endometrial manipulation but caesarean section greatly increases the risk of developing abdominal wall endometriosis. Ultrasound is the most accessible imaging modality along with history and physical examination for establishing a preoperative diagnosis. Clinicians should be aware and highly suspicious of endometriosis in women presenting with pain in the abdomen and/or abdominal mass near the scar following both obstetric or gynecologic surgery. Early diagnosis and treatment can prevent emotional as well as physical distress to the patient. Surgical excision is the best for diagnosis as well as treatment.
