H&E-stained sections show a well-circumscribed neoplasm composed of mildly pleomorphic cells with eosinophilic cytoplasm and slightly distinct borders which are organized around papillae with fibrovascular cores. Most of these papillae envelop nests of myxoid material. Mitoses are present (up to 2/10 HPF) but not abundant. (H&E)
