HELLP syndrome as a cause of unexpected rapid maternal death--a case report and review of the literature.

Unexpected rapid death after delivery due to HELLP syndrome (HS) may become the subject of a forensic expertise. Since this syndrome is rarely encountered in forensic pathology, our objective was to point to some specific findings which might present forensic aspects of HS. These include unexpectedness, suddenness and fulminant course of this syndrome, which may confuse physicians, and on the other hand these characteristics cast doubt on violent injury, diagnostic oversights or iatrogenic injuries. Absence of classical signs of preeclampsia and non-specific clinical symptoms cause considerable differential diagnostic problems leading to a diagnostic delay or initial wrong non-obstetric diagnosis. A definitive postmortem diagnosis of HS in questionable cases of maternal death and consecutive forensic expertise of suspected medical malpractice should be based on accepted laboratory criteria and characteristic histopathological alterations.
