ABSTRACT

This report describes the case of a 77-year-old woman whose chief complaint was non-productive cough. Laboratory examination results revealed anemia; chest unenhanced computed tomography showed diffuse ground-glass opacities in both lung fields. A diagnosis of gastric cancer was established on the basis of the upper gastrointestinal endoscopy findings. However, before chemotherapy could be initiated, she died of respiratory failure. Autopsy revealed widespread tumor emboli with fibrocellular intimal proliferation, thrombus formation in the small arteries, and emboli in the lymph capillary by the tumor cells. Diagnoses of pulmonary tumor thrombotic microangiopathy and lymphangiosis carcinomatosa due to gastric cancer were established.
