Comments:
Immunohistochemistry of Ovarian Carcinoids: They are variably positive for one or more neuroendocrine markers (chromogranin, synaptophysin, NSE, & CD56), cytokeratin, EMA, CK7 and CK20. CDX2, SATB2 and CK20 are positive in areas of intestinal differentiation. Ki67 index is low. The image shows synaptophysin immunoreactivity in an ovarian carcinoid with trabecular architecture.
