Introduction:

We describe the case of a patient with appendiceal metastasis as the first manifestation of a cholangiocarcinoma. Main symptoms: Abdominal pain, jaundice, hyporexia, and choluria.

Methods and results:

We documented an appendiceal plastron histologically compatible with metastatic appendiceal adenocarcinoma, common hepatic duct stricture, and a suspected cholangiocarcinoma, later corroborated by endoscopic retrograde cholangiopancreatography.

Conclusions:

Metastatic appendiceal tumors are an infrequent and poorly studied manifestation, whereas those secondary to bile duct neoplasia have rarely been reported in the literature.
