The majority of cases are positive for cytoplasmic CD3ε, CD2, granzyme B, and TIA-1. Most ENKTLs are of NK-lineage and express CD56. Cases of T-lineage express T-cell receptor (TCR) and show clonal TCR gene rearrangements. All cases are EBV positive by in situ hybridization for Epstein-Barr virus-encoded small RNA (EBER).

Haematolymphoid Tumours (WHO Classification, 5th ed.)

Primary Authors*

Teodora Popa, MD, Queen's University

Amanda Xu, MD, Queen's University

WHO Classification of Disease

Structure Disease
Book Haematolymphoid Tumours (5th ed.)
Category T-cell and NK-cell lymphoid proliferations and lymphomas
Family Mature T-cell and NK-cell neoplasms
Type EBV-positive NK-cell and T-cell lymphomas
Subtype(s) Extranodal NK/T-cell lymphoma

Definition / Description of Disease

  • Lymphoma of NK or T-cell lineage strongly associated with Epstein-Barr virus[1]. The lineage (NK or T-cell) has no clinical significance[2].
  • Divided into nasal and non-nasal types, the latter most often occurring in the skin and intestinal tract[3][1].
  • It is a destructive angiocentric disease characterized by vascular destruction and necrosis[4].
  • Differential diagnosis: sinonasal carcinomas and other lymphomas of the nasal cavity, such as diffuse large B-cell lymphoma[5].

Synonyms / Terminology

Extranodal NK/T-cell lymphoma, nasal type

EBV-positive extranodal NK/T-cell lymphoma

Not recommended: angiocentric lymphoma; lethal midline granuloma (historical)

Epidemiology / Prevalence

  • Most prevalent in East Asia and Latin America.
  • Represents less than 1% of non-Hodgkin lymphomas in the United States
    • Highest incidence among Asian Pacific Islanders and Hispanic populations[6].

Clinical Features

Signs and Symptoms Nasal mass, nasal obstruction, nasal bleeding

Hoarseness, dysphagia, halitosis, airway obstruction, dysphonia

Abdominal pain, GI bleeding, bowel perforation[7]

B symptoms (fever, weight loss, night sweats) associated with higher clinical stage[8]

Laboratory Findings No specific findings

Cytopenias

Sites of Involvement

  • Most are nasal type involving the upper aerodigestive tract
  • Extranasal type may involve skin, testis, and gastrointestinal tract[7].
  • Bone marrow involvement is uncommon[9].

Morphologic Features

Extranodal NK T-cell lymphoma, nasal type (HPS). Angiocentric and angiodestructive growth pattern.
Extranodal NK T-cell lymphoma, nasal type (HPS). Angiocentric and angiodestructive growth pattern.
  • Diffuse infiltrate composed of admixture of small, medium, or large and anaplastic cells.
  • Cells have irregularly folded nuclei and moderate pale cytoplasm.
  • Loss of mucosal glands.
  • Angiocentric and angiodestructive growth pattern with coagulative necrosis.
  • Usually see apoptotic cells and mitotic figures

Pitfalls:

  • Mucosal ulceration and superimposed inflammation can mimic an inflammatory process, particularly in less aggressive cases[10].
  • Pseudoepitheliomatous hyperplasia of the overlying mucosal epithelium can mimic squamous cell carcinoma[11][12].

Immunophenotype

Extranodal NK T-cell lymphoma stained with CD2 (top left), CD56 (red chromogen; top right), EBER in-situ hybridization (bottom left) and TIA1 (bottom right).


Finding Marker
Positive (universal) EBER / EBV
Positive (majority) cytoplasmic CD3ε, CD2, CD56, granzyme B, and TIA-1
Positive (subset) TCR αβ/γδ, HLA-DR, CD25, pSTAT3, CXCL13, IRF4/MUM1, CD16, Fas, FasL, MATK, CD30[13][14][15][16][17][18][19].
Negative (universal) CD4, CD8
Negative (subset) Surface CD3 (subset of T-cell lineage)[7]

Similarly, a 2015 study by Lee, et al reported that histone modification-related genes, including BCOR and KMT2D (MLL2), accounted for 38.2% of 34 ENKTL samples by next-generation sequencing[37].

Genes and Main Pathways Involved

Huang, et al described deregulation of several signaling pathways in NK T-cell lymphoma, main ones listed below[40]. A review by De Mel, et al, also outlines key molecular pathways involved in the pathogenesis of ENKTL[54].

NF-κB related genes[40][54] NF-κB pathway Increased cell proliferation
PDGFRA[40][54] PDGF pathway Increased cell proliferation and survival
NOTCH1[54] NOTCH1 pathway Increased cell proliferation
AURKA[54] Aurora kinase pathway[39] Increased cell proliferation and cell cycle dysregulation

Genetic Diagnostic Testing Methods

  • Select cases may require TCR gene rearrangement studies; otherwise, not routinely performed.
  • EBV PCR testing may be used for disease monitoring
