Abstract(s)

Gastric metastasis is an infrequent occurrence, especially when derived from lung adenocarcinomas. They can grossly resemble advanced gastric cancer and require comprehensive evaluations of the patients and their symptoms.Here, we present the case of a 71-year-old patient admitted to our hospital due to intense, cramping abdominal pain. He had been previously diagnosed with a right lower lobe adenocarcinoma of the lung, which was treated in the previous year with chemotherapy and radiotherapy with good clinical response. The abdominal CT scan and the esophagogastroduodenoscopy showed a gastric infiltrating lesion resembling advanced gastric cancer. However, the biopsy showed malignant epithelial neoplasia with features of adenocarcinoma of pulmonary origin. Even though they are an uncommon finding, gastrointestinal metastases may be life-threatening and should be diagnosed as soon as possible, as the advent of molecular studies and new therapies may result in better survival rates.
