A 2-year-old boy was referred to us in September 2002 with a fetal hepatoblastoma with pulmonary metastasis. Mi-croscopic examination of blood smears revealed red blood cellinclusions consistent with Babesia microti (Fig. 1). The familyreported no previous contacts with wild animals, no priorblood transfusions, and no recent travel. The patient was FIGURE 1. Peripheral blood with red blood cells showing in-

ment evaluation showed no evidence of babesiosis in the pe-ripheral blood. He was then started on chemotherapy using a immunocompromised patients.3 Our patient presented with an combination of cisplatin, carboplatin, and doxorubicin. The tu- asymptomatic form of babesiosis and a moderate degree of mor was completely resected in March 2003 but relapsed lo- parasitemia, which was diagnosed by incidental observation of cally 2 months after surgery. The family refused further treat- the presence of parasites. Confirmatory tests such as PCR or ment and the patient was provided with palliative therapy.
ELISA were not performed in this patient. Malaria could bemisdiagnosed as babesiosis, but the endemic region of this dis- DISCUSSION

Physicians As babesiosis is not a common disease in Brazil, it is should be aware of babesiosis, even in a region with no previ- possible that some cases have been misdiagnosed or not re- ously reported cases. This is particularly relevant when treat- ported. In the past decade, cases of babesiosis in humans have ing immunocompromised patients, who may have severe been reported with increasing frequency, especially in the northeastern United States.6 Most cases of B. microti infectionare relatively asymptomatic in the immunocompetent host.
