A Case of Extranodall NK/T-cell Lymphoma, Nasal type / 대한피부과학회지

ABSTRACT

NK/T-cell lymphomas which are characterized by the biphenotype of the NK-cell and the T-cell are divided into nasal and non-nasal NK/T-cell lymphoma, non-nasal NK/T-cell lymphoma is then further subdivided into primary cutaneous and 4 subtypes of secondary cutaneous lymphoma such as nasal type, aggressive, blastic(blastoid), and other specific NK-like T-cell lymphoma. Primary cutaneous NK/T-cell lymphoma is a very rare condition and defined as a lack of extracutaneous disease for at least 6 months from the time of diagnosis. We herein report a case of non-nasal NK/T-cell lymphoma, which is consistent with primary cutaneous type.
