Core Tip
Core tip: This report describes the rare case of a 68-year-old patient with gastric metastasis from primary lung adenocarcinoma mimicking Borrmann type IV primary gastric cancer. When gastric carcinoma is suspected in patients with primary lung adenocarcinoma, a differential diagnosis of primary gastric cancer and gastric metastasis can be done through special immunohistochemical staining with napsin-A and thyroid transcription factor-1, especially when the biopsy results are ambiguous by histology alone.
