Evaluation of the 2008 World Health Organization classification for non-mycosis fungoides, non-Sezary syndrome T/NK-cell lymphomas with primary cutaneous involvement

摘要

Backgroun: Cutaneous non-mycosis fungoides non-Sezary syndrome T/NK cell lymphomas (non-MFon-SS CTCL) are rare. In 2005, a consensus of the World Health Organization (WHO) and European Organization for Research and Treatment of Cancer (EORTC) classifications for primary cutaneous lymphomas was established. These guidelines were then adopted into the WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues, 2008. This study aims to assess the applicability of the WHO 2008 classification in a retrospective series of CTCL cases registered in a reference academic center in Brazil.
