  • Title: Sarcoma-like mural nodules in mucinous cystic tumors of the ovary revisited: a clinicopathologic analysis of 10 additional cases.
    Author: Bagué S, Rodríguez IM, Prat J.
    Journal: Am J Surg Pathol; 2002 Nov; 26(11):1467-76. PubMed ID: 12409723.
    Abstract:
    Ten mucinous cystic ovarian tumors that contained sarcoma-like mural nodules are described. The nodules were studied by conventional and immunohistochemical methods. The sarcoma-like mural nodules occurred predominantly in middle-aged women, were multiple and sharply demarcated from the adjacent mucinous tumor, had small size, and exhibited a heterogeneous cell population. Distinction of these lesions from true sarcomatous nodules and foci of anaplastic carcinoma is important because of the worse prognosis of the two latter tumors compared with the favorable behavior of the sarcoma-like mural nodules. Six of the eight patients with follow-up information were alive and clinically free of recurrence at a mean follow-up interval of 12 years. Two patients died of other causes (thyroid and breast carcinomas). The nature of the nodules is not clear. Sarcoma-like mural nodules probably represent a reactive and self-limited phenomenon within a neoplasia. Their coexpression of vimentin and cytokeratins is consistent with an origin from submesothelial mesenchymal cells, which undergo partial transformation into epithelial cells.
