PATOMORPHOLOGICAL FEATURES OF THE PITUITARY GLAND IN SUDDEN DEATH CASES

Abstract

Sudden death is a significant medical and forensic concern, often occurring unexpectedly and within a short period. The pituitary gland, as a central endocrine organ, is sensitive to systemic stress, hypoxia, and ischemic injury, which may contribute to mortality. This study aimed to evaluate the patomorphological features of the pituitary gland in 40 cases of sudden death. Histopathological analyses revealed vascular congestion in 65% of cases, microhemorrhages in 30%, cytoplasmic vacuolization and nuclear pyknosis in 50%, and structural alterations including anterior lobe collapse in 25% and reduced posterior lobe staining in 30%. Correlations between specific changes and cause of death were observed, with cardiovascular-related fatalities showing prominent adenohypophyseal congestion, while respiratory-related deaths exhibited neurohypophyseal alterations. These findings indicate that pituitary morphology reflects acute stress responses and potential endocrine involvement in sudden death, providing a valuable tool for forensic evaluation.
