Protozoan Infections in Cancer Patients: A Case Series.

Intestinal parasitic infections can cause significant morbidity and mortality in individuals with cancer. Despite this, they are often self-limiting in healthy individuals. is an anaerobic parasite that causes amebiasis in infected individuals. Poor sanitary conditions and endemic areas increase the risk of contracting amebiasis. Furthermore, giardiasis is a parasitic infection of the small intestine that is caused by , a flagellated protozoan. In both cases, the disease burden is greater and the timeline is longer among immunosuppressed patients. Due to this, we aimed to more thoroughly characterize disease progression and treatment efficacy of these intestinal parasitic infections in cancer patients by presenting a case of intestinal amebiasis and enterocolitis due to as well as two giardiasis cases, while also providing a review of the literature.
