A Case of Nasal CD56+ NK/T Cell Lymphoma Mimicking Cellulitis which Developed after Persistent Orbital Swelling / 대한피부과학회지

Recently another distinct subtype of lymphoma has been discovered, the natural killer (NK)T cell lymphoma, which can involve the skin in a primary or secondary fashion. NK/T cell lymphoma is characterized by the biphenotype expression of the T-cell marker and NK cell marker, especially CD56. These CD56+ lymphomas are further subdivided into nasal NK/T-cell lymphomas and non-nasal NK/T-cell lymphomas. We report a case of primary nasal NK/T cell lymphoma, which showed as an atypical cellulites-like lesion on the face. The patient had suffered with recurrent orbital swelling for several years before diagnosis.
