Objective To investigate the pathological features, differential diagnosis, benign and malignant features of ovarian mucinous cystic neoplasm complicated with adherent nodules and its relationship with prognosis. Methods Two cases of ovarian mucinous cystic tumor with solid appendage nodules were observed and observed by light microscopy and immunohistochemistry. The related literatures were reviewed. Results Example 1 Ovarian mucinous cystadenocarcinoma is associated with the formation of multiple adjunct sarcomatoid nodules consisting of osteoclastic giant cells and mononuclear cells with positive immunophenotype Vimentin (VM). Case 2 Ovarian mucinous Cystadenoma with attached leiomyoma nodules, a large number of nodules spindle cells arranged in a bundle, immunophenotype VM, MSA, Desmin positive. Conclusions Immunohistochemistry is helpful to the diagnosis and differential diagnosis of ovarian mucinous cystic tumor with solid appearing nodules
