  • Pituitary morphology was studied in 49 autopsied patients with acquired immunodeficiency syndrome. Direct infectious involvement was noted in six adenohypophyses (12%), including five cases by cytomegalovirus and one by Pneumocystis carinii. Two cases with neurohypophysial lesions presumably caused by cytomegalovirus and one questionable case of Toxoplasma gondii were also observed. In all instances these changes were associated with generalized and/or cerebral infection by these same agents. Neither Kaposi's sarcoma nor malignant lymphoma was encountered in the pituitary glands. Acute necrotic foci, presumably due to infarction, were noted in four cases. Four pituitary microadenomas (8%) and four hyperplastic nodules were identified. The incidence of such noninfectious lesions, as well as the prevalence and distribution of the various immunoreactive adenohypophysial cell types, were similar to those seen in the pituitary glands of age-matched male control patients.
