[Gallbladder metastasis of large cell lung cancer]

A man, who received right upper lobectomy of the lung due to stage IIB large cell carcinoma 7 and half years ago, visited our hospital complaining of right upper abdominal pain. Computed tomography (CT) revealed gallbladder tumor and extended resection of the gallbladder was performed. Pathological diagnosis was adenosquamous cell carcinoma After 1 year and 4 months later, left adrenal gland tumor was found by CT scan, and the surgery was conducted. Pathologically, it was diagnosed as metastasis from lung cancer. By reevaluation of pathology of the gallbladder, the tumor was found to have similar component of resected lung cancer, suggesting the possibility of the tumor to be metastatic.
