Solid well-demarcated mass with irregular contours in the left upper lobe with retraction of the adjacent pleural surface. There is a small calcified nodule within the mass, probably corresponding to a granulomatous lesion engulfed by the tumor. There is contrast medium enhancement.

Case Discussion

Ultrasound guided percutaneous biopsy diagnosed squamous cell carcinoma of lung origin.

This cell type accounts for ~30-35% of all lung cancers and usually occurs in heavy smokers. Although squamous cell carcinoma of the lung is traditionally a central tumor (66-90%), the incidence of peripheral tumors is increasing and can lead to chest wall invasion.
