Primary pleomorphic adenoma of the lung is a type of pulmonary adenoma that is extremely rare, and it predominantly occurs in the proximal airway. We recently experienced a case of a peripheral solitary pulmonary nodule that was discovered on the CT scans. We performed wedge resection with video-assisted thoracoscopic surgery and we firmly diagnosed this lesion as pulmonary pleomorphic adenoma according to the histology. We report here on a rare benign tumor that was diagnosed as a primary pleomorphic adenoma located in the lung periphery.

We report a rare case of pleomorphic adenoma arising from the nasal septum. A 37-year-old woman presented with a 1-year-history of right-sided occasional epistaxis. Computed tomographic scans revealed an oval mass in the right nasal cavity. The tumor was removed endoscopically with endonasal approach. The microscopic finding showed numbers of myoepithelial cells and duct-like structures consisting of loose myxoid stroma. This lesion had histological characteristics of a pleomorphic adenoma, and this was confirmed by immunohistochemical expression of cytokeratin, S-100 protein and SMA. Her post-operative course was uneventful, and she is currently free from the disease 1.5 years after surgery.
