MULLERIAN CYSTS OF THE MESENTERY AND RETROPERITONEUM - A CASE-REPORT AND LITERATURE-REVIEW

Mullerian cyst of the mesentery and retroperitoneum is an extremely ra re disease entity. Only two photomicrograph reports have been publishe d. A 47-year-old Korean woman presented with abdominal distention, A m esenteric cystic mass, measuring 25 x 23 x 18 cm, was found between th e liver and right adnexa without any connection with adjacent organs. The cyst was multilocular with gray-white, rubbery walls of relatively uniform 0.2 cm thickness. Microscopically, the lining cells were cili ated and cuboidal to low columnar with an incomplete lining of smooth muscle bundles, adipose tissues, lymphovascular spaces, and lymphocyti c aggregates. Ultrastructurally, the lining cells had intercellular ju nctions, and cilia or microvilli on their luminal surface. The lining cells were immunoreactive for cytokeratin, epithelial membrane antigen and vimentin, To the best of our knowledge, this is the first demonst ration of ultrastructural and immunohistochemical findings of Mulleria n cyst of the mesentery and retroperitoneum in the English literature.
