Fig. 3From: The clinicopathological and immunohistochemical features of breast carcinomas with signet-ring-cell differentiationImmunohistochemical expression of MUC1 and MUC2 (magnification × 400). A the expression of MUC1 was localized in the mucous cavity of signet ring-like cells, and the expression intensity was weak. B MUC1 was only positive in individual tumor cells. C MUC1 was expressed in the cell lumen, and the expression around the cell membrane was strongly positive. D–F MUC2 was strongly expressed, and was significantly enhanced compared with peripheral carcinomaBack to article page
