摘要: The differentiation of ovarian metastases from colonic carcinoma and primary can be difficult. To assess the utility cytokeratin 7 20 immunostains in this setting, we studied routinely processed, formalin-fixed tissue 165 tumors, including 45 serous carcinomas, 40 mucinous 64 endometrioid 16 metastatic adenocarcinomas with an avidin-biotin immunohistochemical technique. A 7+/cytokeratin 20- immunophenotype was seen 86% 27% 40% none colorectal carcinomas. Conversely, a 7-/cytokeratin 20+ 94% 5% or tumors. We concluded that helpful distinguishing adenocarcinoma particularly Rare carcinomas may show same as
