Differential diagnosis should include that rare condition and ultrasonography remains a pivotal tool to unravel that enigma as well.\nA 34 years old woman was presented 4 years ago to our facility complaining for pain due to a palpable nodule in the abdominal wall of previous cesarean sections. No other symptom was reported. She had a personal history of two cesarean sections (2007 and 2012), and a laparoscopic surgery for ruptured ovarian cyst in 2013. Clinical examination revealed a palpable lesion in the left abdominal side and precisely into the abdominal wall. Vaginal examination and laboratory examinations were all normal. Transabdominal and translabial ultrasonography were performed (Figures  1  and  2 ). An intra‐abdominal hypogenic lesion of 36 × 15 mm was unraveled via the translabial ultrasound in the median tissue between the abdominal wall and the subcutaneous tissue. Hence, a surgical removal under general anesthesia was performed. Histological diagnosis verified that insidious lesion‐endometrioma. Cesarean section and hysterotomy are the most common operations associated with abdominal wall endometriosis. Pfannenstiel scar remains the most common site for extra pelvic endometriosis with a precise incidence of 0.07%–0.47%. 1  No specific findings and symptoms lead usually to delayed diagnosis. Granuloma, lipoma, abscesses, sebaceous cysts, ventral hernias, or metastasis should be included in the differential diagnosis of those lesions. 2\nTranslabial ultrasonic image; a lesion of 36 × 15 mm is being present in the median tissue between the abdominal wall and the subcutaneous tissue\nHypogenic lesion underneath the scar of the abdominal wall with clear margins and benign characteristics via the transabdominal ultrasonography\n\nThe authors declare that they have no competing interest.\n\nSS made substantial contribution to acquisition of data.
