A Rare Case of Synchronous Gallbladder Metastasis Secondary to Gastric Adenocarcinoma

Background: Gallbladder metastasis is rare and usually presents in the end stage of a malignancy. When they do occur, most of the time it is secondary to melanoma. However, there have been case reports of gallbladder metastasis secondary to gastric cancer; this has been reported in Asian countries such as Japan, South Korea, and Turkey where gastric cancer rates are higher than western countries. This is the first case of gallbladder metastasis secondary to gastric cancer in the United States to ever be reported. Case Presentation: A 67-year-old female initially developed hematemesis, and further workup showed gastric cancer with initial pathology showing T3N0M0. Clinically she was asymptomatic. Patient underwent total gastrectomy with roux-en-y esophagojejunostomy and cholecystectomy. The final pathology showed T3N2M1 gastric adenocarcinoma with metastatic adenocarcinoma of the gallbladder. Conclusion: This is a very rare case adds to the limited literature on this topic. Due to lack of level one data on gallbladder metastasis in general, case reports such as this one provides a unique and valuable insight into this pathology.
