Ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma: report of a case and review of the literature.
Cases of ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma are very rare. We report on such a case and review the literature. The mural nodules in our case were made up mainly of anaplastic spindle cells and numerous osteoclast-like giant cells. They resembled sarcoma or sarcoma-like mural nodules under light microscopy. The anaplastic cells within the nodules were immunopositive for both cytokeratin and vimentin, and ultrastructurally they displayed desmosomes. This case reaffirms the value of immunohistochemistry and ultrastructural study to establish the nature of such nodules, and the importance of making such distinctions.
