Ovarian mucinous tumor with sarcoma-like mural nodules (patient 3). A well differentiated mucinous adenocarcinoma exhibits the confluent growth of interconnecting papillae [a]. The mural nodule is composed of atypical spindle cells arranged in a vaguely fascicular pattern [b, c]. The tumor cells in the mural nodule are vimentin+ [d], CK focal+ [e], and have a high Ki-67 index [f]. (H&E: a, b × 100, c × 200; immunohistochemistry, d-f × 200)
