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.
