篇名	Primary Retroperitoneal Mucinous Cystadenoma: Report of a Case
作者	Wen-Pin Yeh; Ming-Houng Chen
卷期/出版年月	41卷4期 (2008/8)
頁次	147-151
摘要	Primary retroperitoneal mucinous cystadenomas are extremely rare. They are unattached to the ovary and found almost exclusively in women. The pathogenesis of such neoplasms remains uncertain. Herein, we describe a 52-year-old woman who had an en bloc resection of a large retroperitoneal cystic tumor. Microscopic examination of the lining epithelial cells showed features of mesothelial cells in addition to a benign mucinous cystadenoma. These findings suggest that the tumor developed from mucinous metaplasia of the coelomic mesothelium. The mesothelial-like epithelium was positive for estrogen receptors, implicating its role in tumor promotion and the exclusive occurrence of such tumors in women.
