Lymph node pathology is a complex and rapidly evolving field that requires integration of morphologic findings with a number of ancillary studies, as well as clinical information, to diagnose neoplastic and non-neoplastic hematopoietic disorders. Lymphomas are currently classified according to the 2016 Revision of the World Health Organization (WHO) Classification, which emphasizes, and for some diagnoses mandates, the integration of clinical information in diagnostic decision making. Successful collaboration and teamwork between pathology and clinical specialties (especially hematology/oncology) are paramount for excellent patient care. In addition to diagnosis, pathology plays a significant role in lymphoma prognostication and therefore contributes to patient’s management and follow-up.
