Hydatid disease is a rare tapeworm infection that can cause the formation of cysts in the liver and other organs. Although it is uncommon for patients to have both hydatid cysts and cancer at the same time, it is possible, and this can easily be confused with metastasis. Proper management of hydatid cysts in a patient with cancer requires the consensus of oncologists, hematologists, and infectious disease specialists. According to a literature review and investigation of case reports, the treatment approach depends on the stage of the cyst, and chemotherapy management remains unchanged. It is crucial to follow specific treatment guidelines for each stage of the cyst to ensure proper treatment.
