Gastric metastasis by lung small cell carcinoma.

Metastatic tumors of the gastrointestinal tract are rare. We describe a case of gastric metastasis due to primary lung cancer, revealed by an upper gastrointestinal endoscopy (UGIE). Haematogenous metastases to the stomach are a rare event. To our knowledge, only 55 cases have been described in the international literature. In these patients, the prognosis is very poor. We report herein a case of gastric metastasis by lung small cell carcinoma, with a review of the literature about this rare entity.
