Abstract
Nearly 50% of primary lung carcinoma patients present with distant metastasis at their first visit. However, gastrointestinal tract (GIT) metastasis is an infrequent impediment. Herein, we report a case of progressive dysphagia and epigastralgia as an initial manifestation of recurrence as gastric metastasis of primary lung squamous cell carcinoma (SCC) after curative surgery. A 64‐year‐old man was diagnosed with primary lung SCC of the right lower lobe, and underwent thoracoscopic lower lobectomy. One year after lobectomy, computed tomography (CT) scan showed a gastric fundal mass located in the gastric cardia which measured 5 cm. Endoscopic biopsies and histopathology subsequently confirmed that tumor was SCC. The patient then underwent proximal gastrectomy with resection of the diaphragmatic crus. Following surgery, histopathological examination revealed gastric metastasis from primary lung SCC.Key pointsGastric metastasis of primary lung carcinoma is one of the rarest phenomena. Gastrointestinal symptoms should raise suspicion of the presence of advanced metastatic disease with poor prognosis.

GIT metastasis from primary lung carcinoma is one of the rarest phenomena,[1,3–12] and its frequency has been reported to range from 0.19%–5.1%
Summary
Gastrointestinal tract (GIT) metastasis from lung carcinoma signifies a late stage disease resulting from hematogenous tumor spread. We report a case wherein the medical background demonstrated that the patient encountered intensifying dysphagia and epigastralgia as the initial characteristic of gastric metastasis from primary lung squamous cell carcinoma (SCC) after curative surgery. One year prior to the current presentation, the patient had been diagnosed with primary lung SCC of the right lower lobe (Fig. 1a), and had undergone thoracoscopic lower lobectomy.
