The Pituitary Gland: An Infrequent but Multifaceted Contributor to Death.

The pituitary gland has an important role in homeostasis and disorders of it can result in endocrine dysfunction and/or produce mass effect on surrounding structures, including the hypothalamus, which can cause significant morbidity and mortality. A definitive clinical diagnosis may be delayed or remain elusive and lead to life-threatening conditions. Specifically, pituitary adenomas, pituitary necrosis, hypophysitis, and abscesses have all been reported in the literature to cause sudden and unexpected death and may only be first encountered at autopsy. Recognition by the forensic pathologist of these rare entities is crucial for appropriate death certification. This review emphasizes the need for a comprehensive, detailed forensic examination, including autopsy and routine histologic sampling of the pituitary gland, in order to ascertain its potential role in sudden unexpected death with no other apparent cause.
