Mediterranean spotted fever as a cause of septic shock.

Mediterranean spotted fever is a generally benign disease but with the potential of serious manifestations. We report a case of Mediterranean spotted fever in a 56-year-old woman, with pet dog exposure, who presented with a septic shock pattern. Based on clinical symptoms, history, and laboratory results, the diagnosis of Mediterranean spotted fever was suspected and the outcome was favorable with doxycycline treatment. Although rickettsiae remain an uncommon cause of the sepsis syndrome, it is important to consider it, especially as people are now traveling to endemic areas more frequently.
