Question

A 50-year-old man presented to the physician complaining of headaches and difficulty maintaining his balance. On physical exam the physician noticed a lump in the man’s left calf. Initial lab results including a complete blood count and differential were normal. The ESR (erythrocyte sedimentation rate) was slightly elevated, indicating generalized inflammation. The physician asked the man if he had traveled to any areas outside of the United States in the past 12 months. The man had recently returned from volunteering in Haiti. The physician prescribed niclosamide and had the patient collect three stool samples over the next 12 days. Following treatment the following parasite was recovered from the man’s stool with armed rostellum. 18 lateral branches were seen in its proglottids.

Explain the morphologic characteristics that would definitively provide a clear identification of the parasite.
What, if any, additional treatments are available for this patient?

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
