Endobronchial Metastasis with Extension to the Left Atrium from Adenocarcinoma of Gastric 3 Years after Total Gastrectomy.

Endobronchial metastases extending to the heart from gastric cancer are rare. This case report describes a 69-year-old man who presented to a tertiary care hospital in Shahrekord, Iran, in 2022 with a history of cough and haemoptysis. He had previously undergone total gastrectomy and adjuvant chemotherapy for gastric adenocarcinoma three years earlier. Imaging and pathological evaluation confirmed endobronchial metastasis with extension to the left atrium. The patient responded well to chemoradiotherapy, maintaining a good quality of life.
