Gallbladder metastasis of non-small cell lung cancer.
BACKGROUND
Although non-small cell lung cancer is known for its potency to spread to almost any organ of the body, metastasis to the gallbladder with significant clinical manifestation is rarely reported in the literature.


METHODS
We report the case of a 45-year-old man with non-small cell lung cancer (NSCLC), who developed symptoms of acute cholecystitis caused by a metastasis of the gallbladder wall. Histological examination showed tumor cell invasion in regional gallbladder lymph nodes. A second primary tumor of the gallbladder was excluded by immunohistochemical methods.


CONCLUSIONS
Our experience showed that acute cholecystitis can occur in association with metastases of lung cancer to the gallbladder.
