Abdominal wall endometriosis: A rare case report

Abstract

Abdominal wall endometriosis (AWE) is a rare condition that occurs after a caesarean section or pelvic surgery, and it has an incidence of 0.03–1.5% in women with previous caesarean delivery. While commonly seen in the cutaneous and subcutaneous fat tissue at the caesarean scar level, but the involvement of muscle is quite rare. The predominant clinical feature is cyclic pain over the mass; however, the presentation varies. The presence of endometrial tissue in the abdomen, whether cutaneous, subcutaneous, or intramuscular, is called AWE. Its treatment options include excision of the lesion and/or hormonal therapies or ultrasound-guided ethanol injection (sclerotherapy), but wide surgical excision is the treatment of choice in the literature, although it may create a defect in the abdominal wall and may increase the risk of hernia formation. This case report describes the clinical and radiological findings and treatment modalities of endometriosis that has appeared in the subcutaneous tissue with rectus abdominis muscle involvement in a 35-year-old patient at the caesarean scar level.
