Abstract

A 57-year-old woman underwent esophagogastroduodenoscopy due to a continuous drop in hemoglobin levels reaching 7.4 g/dl after treatment with intravenous thrombolytic therapy 1 week earlier because of an ischemic insult. Numerous erosive lesions were found in the gastric corpus. Histological staining of a specimen from the gastric lesions revealed a poorly differentiated adenocarcinoma. Immunohistochemical examination confirmed the diagnosis of gastric metastasis from lung cancer based on positive staining for thyroid transcriptional factor‑1 (TTF-1) and cytokeratin 7 (CK7) as well as via negative staining for caudal-type homeobox‑2 (CDX-2). Chest computed tomography demonstrated a mediastinal mass, measuring 3.2 cm and involving the cervical and supraclavicular lymph nodes. A lymph node was subsequently extirpated. Immunohistochemical examination confirmed the diagnosis of lymph node metastasis from lung cancer by positive staining for TTF‑1 and CK7. Symptomatic gastric metastasis from lung cancer is an extremely rare clinical entity. Transesophageal echocardiography detected a mass measuring 1.6 cm at the mitral valve with pericardial effusion. On the basis of the echocardiographic findings, a malignant origin was suggested a...Continue Reading
