Histopathology, the microscopic examination of tissues, is a keystone of the autopsy examination, providing critical understandings outside what can be observed with the gross examination. In medicolegal autopsies, where the cause and manner of death may be unclear or contested, histopathology plays an especially vital role. This case series emphasizes the important role of histopathological examination in medicolegal autopsies. We present three cases where microscopic tissue exploration through histopathology provided essential information that signifcantly impacted the fnal determination of the cause and/ or manner of death. In the frst case, histopathology revealed subtle myocardial changes indicative of a previously unsuspected cardiac event. The second case demonstrated the utility of histopathology in distinguishing death due to rupture of hepatic cyst from alleged death due to blunt trauma. Finally, the third case highlights how microscopic evaluation identifed a lethal but grossly undetectable disease process related to amniotic ?uid embolism in a postoperative case. These cases illustrate that histopathology is a crucial tool in medicolegal investigations, often providing critical evidence that macroscopic gross examination alone cannot.
