ABSTRACT
Mural nodules in mucinous ovarian tumors are very rare. Since Prat and Scully first described sarcomatous and sarcoma-like mural nodules within mucinous ovarian tumors in 1979, only about 30 cases have been reported in the literature. Pathologically, mural nodules have three different types; i.e. 1) sarcoma-like mural nodule, 2) sarcomatous mural nodule, 3) anaplastic carcinomatous mural nodule. It is important to distinguish sarcoma-like mural nodule from another two type. because the former in the mucinous ovarian tumor has more favorable prognosis than the latter. We report a case of mucinous cystadenoma with sarcoma-like mural nodules in a 23-year-old nulliparous woman.

Mural nodules in ovarian mucinous tumors, whether benign, borderline, or malignant, have been described by several authors since Prat and Scully first described sarcoma or sarcoma-like mural nodules occurring in association with mucinous epithelial neoplasia in 1979. Three distinct types of the mural nodule have been identified; i. e., 1) sarcoma-like lesion, 2) true mesenchymal sarcome, and 3) anaplastic carcinoma simulating a sarcoma. Mural nodules of sarcomatous and carcinomatous foci associated with mucinous ovarian tumors should be separated from sarcoma-like nodules because of the poor prognosis of the former compared to the favorable prognosis of the latter. We experienced a case of ovarian mucinous cystadenocarcinoma with sarcoma-appearing mural nodule of anaplastic carcinoma occurred in a 59-year-old woman and reported with brief review of the literatures.
