WHO classification of lymphoma

Radiopaedia • CC-by-nc-sa 3.0 • de

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 .
