Subpleural Silicotic Nodule Radiographically Resembling to Small Bronchial Carcinoma

A 65-year-old woman had a solitary nodule radiologically appearing as a coin lesion with pleural indentation, suggesting primary lung cancer. Operative findings and histological examination revealed it to be a silicotic nodule. Despite the rarity of this condition, silicotic nodules should be considered among the causes of solitary or small numbers of peripheral pulmonary nodules in adults.
