Differential diagnosis includes a haematoma, desmoid tumour, incisional hernia, sarcoma, metastatic malignancies and suture granuloma. Adenocarcinoma developing from abdominal wall scar endometrioma are aggressive and carry poor prognosis. An awareness of this clinical entity is important to establish its diagnosis early and ultrasound scan, magnetic resonance scan, or a computerised tomographic-guided localization followed by surgical excision provides best outcome. Here in, a case of abdominal wall scar endometrioma is reported and review of pertinent literature is presented.
