Abstract

A 54-year-old woman presented with vaginal bleeding. On gynecologic and radiologic examinations, bilateral cystic ovarian tumors were suspected. A laparoscopic examination revealed multiple cysts involving both the uterine horns and the posterior surface of the uterus. These were removed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. Microscopically, multiple cysts were identified in the subserosal layer of the uterus, and they were lined with benign tubal type epithelium surrounded by a smooth muscle wall. These features were consistent with "florid cystic endosalpingiosis". Considering the location of the lesion, the lesion has to be distinguished from other benign cystic lesions of the uterus and adnexa, including multicystic mesothelioma, serous cystadenoma and mucinous cystadenoma. Awareness of this lesion will facilitate a correct diagnosis by both the clinician and pathologist.
