Abstract

Although hematogenous metastasis of cancer to the gastrointestinal track is rare, it sometime has been reported in patients with malignant melanoma and breast cancer. However, it is extremely rare for lung cancer to metastasize to the stomach, not to mention solitary gastric metastasis. Herein, the authors report a case of a 69-year-old man who was initially diagnosed with lung cancer with synchronous primary gastric cancer which proved to be lung cancer with solitary gastric metastasis after the operation.

Histologic findings of lung mass biopsy specimen. (A) Moderately differentiated adenocarcinoma of acinar type is observed (H&E, ×100).(B) The tumor cells show a strong positive staining for thyroid transcription factor-1 (×100).

Histologic findings of the stomach operation specimen. (A) An undifferentiated diffuse proliferation, suggesting poorly differentiated adenocarcinoma, infiltrating to the submucosa layer with marked lymphovascular invasion is observed (H&E, ×100). (B) The tumor cells show a strong positive staining for thyroid transcription factor-1 (×100).
