Case report - Hyperthermia and nuclear hypersegmentation of blood cells

C Rivière et al. Lab Med. .

Abstract

This case report describes a patient with a medical history of schizophrenia, found in a coma with hyperthermia, likely due to classic heatstroke. The white blood cells observed on the blood smear showed cytological abnormalities characterized by multilobed nuclei, which could be early signs of cell death. The evolution into multiorgan failure led rapidly to death.

Keywords: blood cells; botryoid; cytology; fever; heatstroke; hyperthermia.
