Postoperative pathological and immunohistochemical examination. Hematoxylin–eosin staining showed that tumor cells grew in infiltrating glandular ducts and nests. Heterotypic cells were cubic, with round, dark-stained nuclei, acidophilic and abundant cytoplasm, and proliferation of surrounding fibrous tissue (a, ×200). Immunohistochemical examination showed Ki-67 < 2% (b, ×200), the positivity for CgA (c, ×200), CD56 (d, ×200) and Syn (e, ×200), the negativity for CK-7 (f, ×200) and CK-20 (g, ×200)
