Updates of Peripheral T Cell Lymphomas Based on the 2017 WHO Classification

Abstract

Purpose of Review

This review will describe and update the readers on the recent changes of the 2017 WHO classification in regard to peripheral T cell lymphomas.

Recent Findings

Significant advances in molecular studies have resulted in revisions of the classification as well as introduction of provisional entities (such as breast implant-associated ALCL, nodal PTCL with TFH phenotype).

Summary

Major advances in molecular and gene expression profiling have expanded our knowledge of T cell lymphomas, including updates in the diagnostic criteria and sub-classification which will facilitate in improving patient care and research.
