Challenging Cases in Infectious Disease Hematopathology

 

Although much attention is given to hematologic neoplasms in the differential diagnosis of lymphadenopathy, the patterns of infectious diseases in lymph nodes are also important to recognize. This case-based discussion will highlight 4 challenging cases of infectious disease pathology in lymph nodes, underscoring key morphologic observations and comparing and contrasting entities within the differential diagnosis for each. This session will focus on practical pointers to help you recognize these diseases in your own practice.
