Pathological findings of the resected primary tumor. A loupe image of the primary gastroesophageal region (a HE) shows that the tumor invades the muscular layer in the esophagus and the subserosal layer in the stomach. In the primary tumor, large uniform round-shaped cells with relatively little cytoplasm were arranged in a diffuse pattern (b HE, × 400), and some of the round cells showed prominent features of rhabdoid cells (c HE, × 400). The round tumor cells were prominently vimentin positive (e × 400) and weakly positive for cytokeratin (AE1/AE3) (d × 400). The cells were also positive for SMARCB1 (f × 400). The undifferentiated cells were positive for CD34 (g × 400), but negative for c-kit (h × 400)
