| A 55 year old female, who recently returned from an extensive trip to China, presented to her physician complaining of diarrhea and abdominal cramps. The doctor ordered a complete blood count (CBC), chem 21 panel, and stool for culture and parasite examination (O & P). The CBC revealed pronounced eosinophilia. The chem 21 and stool culture were unremarkable. The O & P revealed suspicious forms like the one below that each measured approximately 140 µm by 80 µm. This patient is most likely infected with: | View Page |
| A 31 year old male missionary worker recently returned from Africa where he helped a small rural community update their sanitation practices. He presented to his physician weak and complained of recent weight loss, abdominal pain, and diarrhea that was often bloody. The doctor ordered a battery of tests including a complete blood count (CBC) and stool for parasite examination. The CBC revealed eosinophilia and anemia. This suspicious form was seen on the wet preparations. It measured 52 µm by 27 µm. What parasite is mostly likely present? | View Page |
| A 16 year old male champion athlete went to his doctor complaining of a persistent cough, fever, bloody diarrhea and overall weakness. Upon questioning the patient, it was learned that he had recently competed in a freshwater swimming competition in the Caribbean. Examination revealed a dermatitis on the patient's right calf. A battery of tests were ordered including a CBC, chemistry profile, and a stool for culture and parasitic examination. The CBC revealed the presence of eosinophilia. The other hematology and chemistry tests were unremarkable. The culture was negative. This suspicious form was seen on all parasite preparations made from the stool sample submitted. This form measures 165 µm by 68 µm. This patient is most likely suffering from an infection with: | View Page |

| Eosinophilia Follow-Up As mentioned on the previous page, high percentages of eosinophils may be present in the peripheral blood smears of patients with a variety of conditions--asthma, urticaria, Loeffler's syndrome, larval parasitic infections and in chronic eosinophilic leukemia. One exception to the association of eosinophilia with parasitic infections is a fatal case of disseminated strongyloidiasis reported many years ago by Miale (Hematology--5th Edition, Mosby, pg. 776, 1977) in which the peripheral blood eosinophilia was masked by the administration of corticosteroids. | View Page |
