Pulmonary mucinous cystadenoma: a rare benign tumor of the lung

Gen Thorac Cardiovasc Surg. 2010 Jun;58(6):287-90. doi: 10.1007/s11748-009-0519-9. Epub 2010 Jun 13.


Pulmonary mucinous cystadenoma (PMCA) is rare, with few reported cases. This tumor is histologically characterized by a benign proliferation of mucin-producing epithelial cells and bulky mucin inside the tumor. We present the case of a 71-year-old woman with increasing mass shadow on chest radiography who underwent tumor resection by video-assisted thoracic surgery. The tumor was diagnosed histologically as PMCA.
