A 76-year-old woman was admitted to ICU for sepsis. Her medical history consisted of follicular lymphoma with bone marrow invasion diagnosed in 1999. She was treated with three courses of chemotherapy, and a splenectomy was performed in 2009. She reported a 3-day history of fever, asthenia and nausea. Dark urine (Fig. 1a) and jaundice revealed a hemolytic syndrome. Blood smear showed no schistocytes, but identified intracellular Babesia sp. (2.1% parasitemia) (Fig. 1b). The patient remembered a tick bite 2 weeks before. She was treated with clindamycin and intra venous quinine for 2 days. Day 2 parasitemia at 0.9% allowed switching to oral atovaquone and azithromycine. Babesia is a tick-borne disease with inoculation of protozoan parasite Babesia. It mostly occurs among immunocompromized patients especially after splenectomy and presents with an acute hemolysis syndrome. Acute respiratory syndrome and disseminated intravascular coagulation are the more frequent complications leading to a mortality rate up to 40%.×
