Benign Mimics of Hematopoietic Neoplasms


Benign lymph node conditions may pose a significant diagnostic challenge. Although many morphologic features of the benign lymphadenopathies can overlap with the neoplastic processes, their distinction is essential. This presentation will address common diagnostic dilemmas and share a practical approach to resolve them. This case-based presentation of clinically relevant non-infectious lymphadenopathies can be particularly beneficial to the general pathologists and hematopathologists.

After this presentation, participants will be able to:

  • Demonstrate an approach to lymph node assessment
  • Describe a comprehensive differential diagnosis for common patterns of lymph node involvement
  • Compare and contrast clinically relevant benign entities to their neoplastic counterparts
  • Recognize the importance of thorough morphologic evaluation in lymph node pathology
