BACKGROUND Primary lung cancer is the leading cause of cancer-related death worldwide.Common metastatic sites include the brain,liver,bones,and adrenal glands.However,gastric metastases from lung cancer are rare.This case may be the first report of a combined gastroscopic and laparoscopic resection for gastric metasta-tic adenosquamous carcinoma(ASC).CASE SUMMARY We report a case of gastric metastasis from lung cancer.The patient was a 61-year-old Han Chinese female who first attended our hospital complaining of a per-sistent cough,leading to the diagnosis of advanced-stage lung adenocarcinoma.After more than four years of chemotherapy,the patient began to experience epi-gastric pain.Endoscopy was performed,and pathological examination of biopsy specimens confirmed that the gastric lesion was a metastasis from lung cancer.The lesion was successfully resected by combined gastroscopy and laparoscopy.Histopathological examination of the resected gastric specimen revealed ASC.CONCLUSION Gastric metastases from lung cancer are rare.Endoscopy,histological and immunohistochemical staining are useful for diagnosing metastatic lesions.Surgical management may provide extended survival in appropriately selected patients.
