A case of signet ring cell carcinoma of gallbladder diagnosed with EUS-FNA

Abstract

An 70-year-old man was admitted to our hospital with acute pancreatitis. At that time, the CT showed a mass lesion from the gallbladder to the liver and enlarged lymph nodes from the para-aortic to hepatoduodenal ligament. He underwent EUS-FNA for those lesions. The pathological diagnosis was signet ring cell carcinoma and metastasis to lymph nodes. As the gemcitabine+cisplatin chemotherapy were not worked, the S-1 monotherapy were added but they were not succeed. He died for 8 months from the first contact. The case of gallbladder signet ring cell carcinoma is rare and EUS-FNA was useful for diagnosis in this case.
