Figure legends
Figure 1. Endoscopic images.
Type 4 advanced gastric cancer-like sclerosis and poor extension of
gastric wall are observed.
Figure 2 and 3. Pathologic findings of invasive lobular
carcinoma metastasis.
Hematoxylin and eosin (H&E)-stained images show poorly differentiated
adenocarcinoma infiltrating into the gastric lamina propria in a
trabecular or an isolated pattern. Estrogen receptor (ER) shows varying
degrees of positive expression in carcinoma cells, whereas progesterone
receptor (PgR) expression is restricted to a few carcinoma cells.
E-cadherin is mostly negative, but weak and incomplete expression can be
seen in some carcinoma cell membranes. GATA binding protein 3 (GATA3) is
diffusely positive. Gross cystic disease fluid protein 15 (GCDFP15) is
reactive. Cytokeratin 7 is positive, and cytokeratin 20 is negative.
