Unsolved Mystery of Synchronous Metastatic Adenocarcinoma and Echinococcus Cystic Infection, a Major Break Through in Clinical Oncology: A Case Report

Abstract

Echinococcus cystic infection is a zoonotic infection caused by the larval stage of cestode species belonging to the genus Echinococcus. Through the modulation of the immune system by this parasite, there is an established link of this infection with the metastasis and progression of a tumor. We present a case of a patient with synchronous findings of metastatic adenocarcinoma with unknown primary along with the previous history of echinococcal infection, which highlights the need for prompt management of such infections with a regular follow up of such patients.
