title: Large cystic uterine adenomyoma showing marked epithelial metaplasia and exophytic polypoid growth.
abstract: METHODS
  This report describes an unusual case of large cystic uterine adenomyoma in a 48-year-old woman. Under the clinical diagnosis of ovarian cancer, she underwent hysterectomy with bilateral salpingo-oophorectomy. Macroscopically, the large cystic mass containing bloody material was connected with the uterine isthmus and separate from both ovaries. Histological examination showed various epithelial metaplasia lining the cystic surface and revealed focal endometrial stroma in the cystic wall.
  
  
  CONCLUSIONS
  Hence, cystic adenomyoma showing exophytic polypoid growth is suggested, although its occurrence is extremely rare. The present case emphasizes that cystic adenomyoma showing extensive metaplastic changes and exophytic growth can occur.
