Abstract
We report a recently observed case of primary umbilical endometriosis without previous pelvic surgery. A 41-year-old Japanese woman complained of umbilical nodular tumor. Histopathology revealed endometriosis of an approximate 10 mm resected mass. The stromal cells in endometriosis were immunohistochemically positive for CD10. Two months later the first umbilical surgery, she underwent a left salpingo-oophorectomy and release of adhesion around the left adnexa under a laparoscope. She was treated with dienogest (2 mg/day) for six months after four injections of GnRH analogue for four months. After three years of the follow-up, there were no signs of local relapse and no clinical and ultrasonographic abnormalities due to endometriosis.

Summary
Endometriosis is defined as the presence of endometrial glands and stroma abnormal located outside the uterine cavity. It is a benign gynecological disorder affecting 10% - 15% of all women of reproductive age and presents an important cause of infertility [1] [2]. Clinical manifestations show the pelvic pain arising around menstration, menhorrage, painful intercourse, intestinal and urinary complaints [4] [5]. Extra-pelvic endometriosis has been described in almost every organ (i.e. gastro-intestinal organ, skin, diaphragm, lung and brain) [2]-[5]. Umbilical endometriosis (UE) is known as Villar’s nodule, named after the physician who first described the disease in 1886 [6]. We report here our recently observed case of UE without a previous surgery
