Burkitt lymphoma of the ovaries mimicking sepsis: a case report and review of the literature.

Background: It is not unusual for systemic diseases to mimic sepsis and, in any case, the clinician should thoroughly investigate this possibility.

Case Presentation: We present the case of a 21-year-old Greek woman who presented to the Intensive Care Unit of our hospital with severe septic shock - multiple organ failure as a result of a suspected gynecological infection of the ovaries. An immediate improvement of her clinical condition in combination with strong clinical suspicion and negative cultures led to the differential diagnosis of diseases other than sepsis.
