Abstract
EORTC classification is used usually among dermatopathologists, and hematopathologists to adapt a new WHO classification to cutaneous lymphoma. There are some differences between both classifications, especially the concept of follicular and B large cell lymphoma, T/NK cell lymphoma, blastic NK cell lymphoma and ATLL. These problems were discussed from the standpoint of the hematopathologist and modified new WHO classification was proposed for practical use. [Skin Cancer (Japan) 2004; 19: 313-321]
