In this daily practice, the forensic pathologist is rarely confronted with postmortem hyperthermia associated with the rapid onset of rigor mortis. We report 2 similar cases where the rectal temperature value taken during the on-scene investigations by the forensic pathologist was greater than 40°C (104°F) in both cases, and rigor mortis was complete within less than 6 hours postmortem. The first case was due to a deadly intoxication by ecstasy and the second one to the deadly association of methadone and a possible neuroleptic malignant syndrome. Infection-related deaths were eliminated. Thus, the association of postmortem hyperthermia and rapid-onset rigor mortis would suggest in the first hypothesis a toxic death, particularly 3,4-methylenedioxymethamphetamine. However, an autopsy and toxicological analysis are necessary to confirm the cause of death.

The molecular basis of McCune Albright syndrome (MAS) is a recurrent GNAS Postzygotic gain of function sporadic mutation, resulting in a mosaic disease. Most of girls present precocious puberty, caused by the development of recurrent ovarian cysts with autonomous Hyperestrogenic stimulation. After menarche, the majority of patients with ovarian GNASmutation have menstrual disturbances and infertility.
