Abstract
A 79-year-old woman consulted her doctor due to cough and sputum in March 2005. A chest X-ray showed a tumor shadow 6 cm in size. Chest CT revealed a tumor 6×5 cm in size and air in the bronchi located in S9 of the left lower lung lobe. A transbronchial lung biopsy (TBLB)was done, but a tumor was not diagnosed. Two months later, the tumor was found to have slightly decreased in size. Therefore, pneumonia was diagnosed ; the patient was treated and followed. However, in July, 2007, the tumor was found to have enlarged in size. A bronchioloalveolar adenocarcinoma was diagnosed on TBLB. A left lower lobectomy was done. The tumor was 9×8 cm in size soft and solid on histopathology, a mucinous type bronchioloalveolar carcinoma was diagnosed. Due to the difficultly in making a diagnosis surgery was delayed by 2 years 8 months.
