Nodal Presentation of Nasal-Type NK/T-Cell Lymphoma

Abstract

Nodal presentation of NK/T-cell lymphoma, though rare, is diagnosable on the basis of fine needle aspiration biopsy alone, especially in view of its distinctive immunophenotype and EBV association. Recognition of the subtle but definite cytologic atypia of malignant lymphoid cells and presence of an appropriate background (including more eosinophils than usual), together with proper application of ancillary techniques, is crucial to arriving at a correct diagnosis.
