[Small pelvis lipoma spreading to the gluteal region].

We present a 36-year-old woman with small pelvis lipoma spreading to the gluteal region through the greater sciatic foramen. Resection of lipoma was performed via two accesses (lower median laparotomy and semilunar incision in the gluteal region). The tumor was the content of sciatic hernia that is extremely rare. Combination of surgical approaches can provide favorable outcomes in these patients.
