Primary abdominal wall clear cell carcinoma arising from incisional endometriosis

A 49 year–old patient with the complaint of a mass located in the caesarean scar was admitted. There was a fixed mass 30×30 mm in diameter with regular contour located at the right corner of the pfannenstiel incision. Computed tomography revealed a (40×50×50) mm solid mass lesion with margins that cannot be distinguished from the uterus, bladder and small intestines and a heterogeneous mass lesion (50×45×55) mm in diameter, located in the right side of the anterior abdominal wall. Cytoreductive surgery including total abdominal hysterectomy and bilateral salpingo–oophorectomy was performed. Final pathology was clear cell carcinoma. Clear cell carcinoma arising from an extraovarian endometriotic focus was diagnosed and the patient received 6 cycles paclitaxel–carboplatin chemotherapy as adjuvant treatment. The patient who was lost to follow–up applied to our clinic 2 years after surgery with a recurrent mass in the left inguinal region. After 3 cycles of chemotherapy, the patient's tumoral mass in the left inguinal region was excised. The result of the pathology was carcinoma metastasis. It is decided that the following treatment of the patient should be palliative radiation therapy. The patient who underwent palliative radiation therapy died of disease after 4 months of the second operation.
