Angioimmunoblastic lymphadenopathy following typhoid AB vaccination and terminating in disseminated infection

Angioimmunoblastic lymphadenopathy (AIL) followed typhoid AB vaccination in a patient whose subsequent clinical course was rapidly progressive. At autopsy, extensive lymphadenopathy with features characteristic of AIL and disseminated infection with Escherichia coli, Candida, and Aspergillus were seen. Vaccination is a presumptive precipitating factor in AIL.
