Dear students,
Added the changes in WHO 5th edition in the video discussion of CEL along with pointers in the digital slide.  

Few pointers - Note that these criteria have changed since the 4th Edition, specifically a reduction in the time interval required to define sustained HE from 6 months to 4 weeks, requirement for both clonality and abnormal bone marrow morphology, and removal of the possibility to define CEL-NOS by increased blasts (≥ 2% in peripheral blood or 5–19% in bone marrow) as an alternative to clonality.
