Sudden death due to thrombotic thrombocytopenic purpura.

This case studies the clinical, laboratory, and pathologic findings observed in thrombotic thrombocytopenic purpura (TTP). Although TTP is a well-recognized syndrome, it is frequently undetected antemortem and represents a rare cause of sudden death. We recently were involved in a case of TTP in which an 18-year-old woman with no previous history died suddenly. The case was referred to our office for consultation because of a recent history of methamphetamine abuse. We report herewith our approach to the diagnostic workup of TTP and review relevant literature.
