[Pleomorphic adenoma of the lung]

A 41 year-old male was admitted to our hospital, because a suspicious shadow in the right lower lung field was on X-ray. Investigations could not confirm cancer but were highly suggestive of it. Finally, right lower lobectomy was performed, and the histopathological finding of the tumor resected were a mixture of epithelial components in myxomatous tissue, so a diagnosis of pleomorphic adenoma of the lung was made.
