Abstract

Endobronchial metastasis (EBM) is a rare form of metastasis from extrapulmonary malignant tumors, although there are few reports of EBM from gastric cancer specifically. We report the case of a 51-year-old woman who had undergone gastrectomy for advanced gastric cancer seven years previously but was diagnosed with a solitary lung tumor by follow-up computed tomography. On diagnosis of primary lung cancer, she underwent pulmonary lobectomy, but immunohistochemical examination confirmed the resected tumor to be an EBM from the gastric cancer. Six months later, she was diagnosed with peritoneal metastases and underwent chemotherapy with gastric cancer regimen. She is still alive at 33 mo after the lobectomy. Generally, the prognosis for EBM is poor although multidisciplinary treatment can lead to long-term survival. Precise diagnosis on the basis of detailed pathological and immunohistochemical evaluation can contribute to deciding the most effective treatment and improving prognosis.
