Second Primary Lung Cancer with Glottic Laryngeal Cancer as Index Tumor - A Case Report

Patients with laryngeal cancer have a high risk of developing lung cancer in the future. A patient presented with a complaint of left-sided chest pain for the last 3 months. Chest X-ray posterior-anterior view showed a homogeneous opacity in the left upper lung field with elevation of the diaphragm on the left side. CECT thorax revealed a heterogeneously enhancing soft tissue density mass lesion in the superior segment of the lingular lobe. On histopathological examination of the mass lesion, it was diagnosed as adenocarcinoma of the lung. About 10 months previously, the patient was treated for a laryngeal squamous cell carcinoma. Patients with laryngeal cancer should be routinely screened during follow-up with chest X-ray or CT scan for the early detection of lung cancer.
