Overview

Extranodal NK-T-cell lymphoma must be differentiated from other diseases such as NK cell lukemia, lymphomatoid granulomatosis, EBV-positive diffuse large B cell lymphoma, NOS, anaplastic large cell lymphoma, non specific inflammatory process, enteropathy associated T cell lymphoma, peripheral T cell lymphoma, hepatosplenic T cell lymphoma

Extranodal NK/T-cell lymphoma, nasal type must be diffrentiated from Wegner's granulomatosis, Polymorphic reticulosis, and Midline malignant lymphoma

Differential Diagnosis

  • Extranodal NK t-cell must be differentiated with other NK and T cell hematologic malignancies and EBV-associated T cell or NK cell lymphoprolifrative disorders.[1]
  • Extranodal NK-T cell lymphoma, nasal type shows aggresive lethal midline granuloma macroscopicaly so it must be differentiated from diseases such as:[4]

Differentiating extranodal NK T-cell from other hematologic malignancies by immunophenotype and EBV infection:

Extranodal NK T-cell lymphoma express CD56 on its surface accompanied with EBV infection.

Malignancies based on immunophenotype and EBV infection
Disease Immunophenotype EBV
NK cell leukemia CD16+ +
Lymphomatoid granulomatosis CD20+ +
EBV-positive diffuse large B cell lymphoma, NOS CD20+ CD76+ +
Peripheral T cell lymphoma, unspecified CD3+ CD56- -
Anaplastic large cell lymphoma CD30+ -
Hepatosplenic T cell lymphoma CD2+ CD7+ CD3+ -
