Here we report the case of a 62-year-old female with stage IV gallbladder cancer who presented to the ED four months after initiation of her cancer treatment. Diffuse abdominal pain was her only presenting symptom and contrast-enhanced CT imaging revealed findings consistent with acute appendicitis. Prompt surgical treatment with laparoscopic appendectomy was initiated. Surprisingly, the histologic analysis was consistent with gallbladder primary metastatic adenocarcinoma to the appendix rather than primary adenocarcinoma of the appendix.}
