A unique case of laparoscopically resected gastric adenocarcinoma concurrent with lanthanum deposition

We present a unique case of laparoscopically resected gastric adenocarcinoma with concurrent lanthanum deposition. Lanthanum depositions occasionally appear similar to carcinomas on endoscopy. and surgical resection should be considered for such concurrent carcinoma. Furthermore, more research is needed to clarify the relationship between carcinogenesis and lanthanum deposition.
