Lung Cancer Along with a Mediastinal Mature Cystic Teratoma: A Case Report

ABSTRACT

A mediastinal mass and 2 lung masses on the lower lobes were detected by chest CT in a 44-year old woman. The mass on the left lower lobe was diagnosed as an adeno type of cancer by preoperative lung biopsy. But the preoperative lung biopsy exam for the mass on the right lower lobe couldn't perform because of patient's noncooperation. Removal of the mediastinal mass, left lower pulmonary lobectomy and wedge resection of the right lower pulmonary lobe were done. The histopathologic diagnosis of the resected mediastinal mass was mature cystic teratoma and both lung masses were the adeno type of cancer with the same histopathologic patterns. We experienced a rare case of lung adeno cancer together with mediastinal mature cystic teratoma.
