Why the study?
Pulmonary tumor embolism is a rare condition presenting with dyspnea in cancer patients, and effective treatment options remain limited and under investigation.
Highlights a rare presentation of pulmonary tumor embolism in a patient with metastatic liver carcinoma and primary breast carcinoma.
Warrants consideration of pulmonary tumor embolism in cancer-associated dyspnea; leaves open incidence and management in metastatic disease.
Pulmonary tumor embolism (PTE) is a rare phenomenon typically presenting as dyspnea in cancer patients. Primary pathophysiology is similar to the thromboembolic disease of the pulmonary vasculature, which involves large vessels to small arterioles. This phenomenon occurs mostly in lung, stomach, liver, and breast adenocarcinoma. The symptoms of hypoxemia and the signs of hemodynamic instability and high-resolution computed tomography (CT) scans, along with a histopathological examination, are essential to make a confirmatory diagnosis of pulmonary tumor embolism. However, treatment options to effectively treat pulmonary tumor embolus are limited and still under investigation. We present a rare case of pulmonary tumor embolism in a patient with metastatic liver carcinoma and its management in a female with primary breast carcinoma.
