An Unusual Primary Paraneoplastic Manifestation of Adenocarcinoma of Lung

Carcinoma of lung (CoL) is the fourth most common cancer in India. It is classified as either small-cell or non-small-cell lung cancer, with adenocarcinoma being the most common variant. CoL can present either as paraneoplastic or non-paraneoplastic manifestation. We discuss a case of a patient who had an abrupt onset of sustained ventricular tachycardia and was subsequently diagnosed with metastatic non-small cell lung cancer with no cardiac infiltrates.
