Abstract

Lung cancer is the leading cause of cancer-associated mortality, with a 5-year survival of 19% for all types of lung cancer. Lymphoid malignancies of the lung have a significantly better prognosis, with 5-year survival approaching 90%, making it very important to identify these patients. As the signs and symptoms, laboratory investigations, and radiological features are non-specific and vague and the histological confirmation is invasive, they are usually either not diagnosed or diagnosed very late. We present a case of an elderly male who was treated for months with antituberculosis treatment (ATT) before being properly evaluated and diagnosed with primary pulmonary marginal cell lymphoma. This case was unique for having gross pleural effusion as a presenting feature and having been diagnosed with the help of radial endobronchial ultrasound (EBUS).
