The patient is in supine position (a). After marking the skin incision (b), a median lower abdominal laparotomy is performed (c) followed by careful depth preparation via transperitoneal approach to expose the tumor (*) while preserving the iliac vessels (↓) and uterus (+), which are in close relation to the mass (d). After exposing the pseudocapsule (-), an optimal entry point into the tumor is identified using electrostimulation for subsequent enucleation with preservation of the sciatic nerve (N); (e). At the end of the operation, the remaining fascicle-bearing capsule is left intact (f)
