RESUMO
Primary breast lymphoma (PBL) is a rare clinical presentation of localized non-Hodgkin's lymphoma (NHL), and it makes up 0.04~1.1% of all breast tumors and it is 0.38~0.7% of all NHLs. The prognosis and patterns of relapse of PBL are still not clearly defined. The clinical features of PBL are different from those of breast carcinoma and the usual form of lymphoma. These features are a rapidly enlarging breast mass, multiple lesions, the absence of nipple discharge and retraction, and softer axillary lymph nodes as compared to the metastatic lymph nodes from breast carcinoma. B symptoms are unusual in PBL. A 30-year-old pregnant woman was admitted due to dysarthria and right side weakness that she had experienced for 7 days. She had several medical problems: intrauterine pregnancy at 34 weeks, some neurologic deficits and enlargement of both breasts. A biopsy from the breast and a brain magnetic resonance image (MRI) revealed diffuse large B cell lymphoma and multiple brain metastases, respectively. After delivery of a healthy, premature infant by Cesarean section, whole brain radiation therapy and combination chemotherapy (rituximab, cyclophosphamide, adriamycin, vincristine and prednisone) were started. She showed good response to therapy. We report here on this unusual case and we review the related literature.

Human babesiosis is a tick-borne infectious disease caused by Babesia species. The clinical diagnosis is difficult because of nonspecific symptoms like flu. Rapid diagnosis of human babesiosis is microscopic examination in peripheral blood smear (Giemsa-stain) which reveals characteristic forms of an intracellular quadruplet parasite. But differentiation between Babesia microti and Plasmodium species can be quite difficult because of the morphologic similarity. We experienced a case of human babesiosis. The patient was a 62-year old Korean male who had been in New Jersey, U.S.A for 2 months. We initially diagnosed as malaria infection because the peripheral blood smear revealed intracellular single ring form organism. But the patient was not improved significantly by the treatment with chloroquine regimen. Finally we confirmed human babesiosis by polymerase chain reaction for Babesia microti. We treated the patient successfully with a regimen of atovaquone and azithromycin which has fewer adverse reactions than a regimen of clindamycin and quinine.
