Abstract:
Ovarian endometrioid adenofibroma is rare and characterized by prominent stroma. Its histologic classification is controversial but the malignant counterpart is distinguished from the borderline by the presence of confluent growth pattern of epithelium with invasion of the stroma by the endometrioid cells. A fifty-year-old woman was admitted with one month history of abdominal enlargement. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed under the clinical diagnosis of ovarian malignancy. Grossly, the righy ovary had round, encapsulated, solid and whitish gray mass which measured 9 cm in the greatest dimension and showed peripheral small cysts. Microscopic examination revealed that the tumor consisted of endometria type glands set in fibrous stroma. The glands varied from tubules to cysts and the lining cells showed complicated architectural pattern with occasional papillary infoldings, atypical mitosis and malignant nuclear characteristics. Some cysts of glands showed intraluminal mucin products. Stromal invasions by individual epithelial cells showing malignant characteristics were often found. A brief summary of the histopathologic aspect of this tumor is presented together with review of literatures.
