WHO classification of lymphoma

The World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues is the most widely used pathologic classification system for hematolymphoid neoplasms. The current revision, known as the 4 revised edition, was published in 2016 and supersedes the 4edition published in 2008.

The current 2016 version forms the basis of the article below .
