Abstract
Malignant pleural mesothelioma (MPM) is a rare, locally invasive tumor that develops from mesothelial cells lining the lung's pleura. It is mostly associated with prolonged asbestos exposure. The long latency period between asbestos exposure and clinical symptoms makes diagnosing MPM challenging. This report describes a 57-year-old Hispanic female who presented with a persistent nonproductive cough and was ultimately diagnosed with advanced-stage pleural mesothelioma after extensive work-up. It highlights the difficulties in diagnosing MPM in patients without apparent asbestos exposure independent of age or gender.
