Figure 2

Breast and gastric biopsy and immunohistochemical analysis. Breast biopsy showed invasive carcinoma with signet-ring cells (hematoxylin and eosin, magnification × 100) (A). Gastric biopsy showed infiltration from a diffuse-type low-grade gastric adenocarcinoma with signet-ring features (hematoxylin and eosin, magnification × 100) (B). Immunohistochemical analysis revealed mammary tumor cells were positive for ErbB2/HER2 (C), CK7 (D), CK20 (E), and villin (F), but negative for ER (G), PR (H), and GCDFP-15 (I) (3,3′-diaminobenzidine, magnification × 100).
