Case: A 36-year old woman complaining of a mass of the abdominal wall with pain during the menstrual period, with a caesarean section 5 years earlier, presented a rounded tumour not contiguous to the Pfannenstiel’s laparotomy scar, of hard consistence, fixed and adherent to the deep abdominal wall structures, located on the left paramedian epigastric region. Magnetic Resonance imaging showed the nodule, involving the deep layers of the abdominal wall and the distance from the laparotomic scar. Surgical removal was performed with wide excision of the lesion, causing a large wall defect. After histological confirmation (endometriosis) by frozen section, reconstruction of the abdominal wall required prolene mesh grafting. After twelve months the patient is healthy. Conclusion: When abdominal wall endometrioma is located distant from the scar, perhaps more frequently after Pfannenstiel’s laparotomic incision, the differential diagnosis may be more difficult and MRI can help differentiating many of these lesions, and histological confirmation should be obtained intraoperatively, by frozen section, to allow an oncological resection if required.展开更多
