FAVACHO, Alexsandra Rodrigues de Mendonça et al. Fatal Brazilian spotless fever caused by Rickettsia rickettsii in a dark-skinned patient. Rev. Soc. Bras. Med. Trop. [online]. 2011, vol.44, n.3, pp. 395-396. ISSN 0037-8682. http://dx.doi.org/10.1590/S0037-86822011000300028.
Brazilian spotted fever (BSF) is the most important and frequent rickettsial disease in Brazil. A fatal case of BSF is reported in a 32-year-old black man, who died of irreversible shock after five days of fever, severe headache and abdominal pain with no rash. Spleen, kidney and heart samples collected at autopsy were positive for Rickettsia rickettsii by PCR and sequencing. The authors emphasize the need for a high index of diagnostic suspicion for spotted fever in black patients. Absence of a skin rash should not dissuade clinicians from considering the possibility of BSF and initiating empirical therapy.
