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). Other markers that may be expressed include HLA-DR, CD25, pSTAT3, CXCL13, IRF4/MUM1, CD16, Fas, FasL, MATK, and CD30<ref>{{Cite journal|last=Li|first=Shaoying|last2=Feng|first2=Xiaoli|last3=Li|first3=Ting|last4=Zhang|first4=Shuang|last5=Zuo|first5=Zhuang|last6=Lin|first6=Pei|last7=Konoplev|first7=Sergej|last8=Bueso-Ramos|first8=Carlos E.|last9=Vega|first9=Francisco|date=2013-01|title=Extranodal NK/T-cell lymphoma, nasal type: a report of 73 cases at MD Anderson Cancer Center|url=https://pubmed.ncbi.nlm.nih.gov/23232851|journal=The American Journal of Surgical Pathology|volume=37|issue=1|pages=14–23|doi=10.1097/PAS.0b013e31826731b5|issn=1532-0979|pmid=23232851}}</ref><ref>{{Cite journal|last=Jhuang|first=Jie-Yang|last2=Chang|first2=Sheng-Tsung|last3=Weng|first3=Shih-Feng|last4=Pan|first4=Shien-Tung|last5=Chu|first5=Pei-Yi|last6=Hsieh|first6=Pin-Pen|last7=Wei|first7=Chih-Hsin|last8=Chou|first8=Shih-Cheng|last9=Koo|first9=Chiew-Loon|date=2015-02|title=Extranodal natural killer/T-cell lymphoma, nasal type in Taiwan: a relatively higher frequency of T-cell lineage and poor survival for extranasal tumors|url=https://pubmed.ncbi.nlm.nih.gov/25554090|journal=Human Pathology|volume=46|issue=2|pages=313–321|doi=10.1016/j.humpath.2014.11.008|issn=1532-8392|pmid=25554090}}</ref><ref>{{Cite journal|last=Pongpruttipan|first=Tawatchai|last2=Sukpanichnant|first2=Sanya|last3=Assanasen|first3=Thamathorn|last4=Wannakrairot|first4=Pongsak|last5=Boonsakan|first5=Paisarn|last6=Kanoksil|first6=Wasana|last7=Kayasut|first7=Kanita|last8=Mitarnun|first8=Winyou|last9=Khuhapinant|first9=Archrob|date=2012-04|title=Extranodal NK/T-cell lymphoma, nasal type, includes cases of natural killer cell and αβ, γδ, and αβ/γδ T-cell origin: a comprehensive clinicopathologic and phenotypic study|url=https://pubmed.ncbi.nlm.nih.gov/22314189|journal=The American Journal of Surgical Pathology|volume=36|issue=4|pages=481–499|doi=10.1097/PAS.0b013e31824433d8|issn=1532-0979|pmid=22314189}}</ref><ref>{{Cite journal|last=Jaffe|first=E.

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).

Epigenomic Alterations

A 2015 study by Lu, et al uncovered recurrent mutations in the RNA helicase gene DDX3X and other epigenetic modifiers including KMT2D (MLL2), ARID1A, EP300, and ASXL3[35].

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[41]. A review by De Mel, et al, also outlines key molecular pathways involved in the pathogenesis of ENKTL[47].

Gene; Genetic Alteration Pathway Pathophysiologic Outcome
JAK3, STAT3, and STAT5B; Activating mutations JAK/STAT pathway Increased cell growth and proliferation
MYC, RUNX3 MYC Increased cell proliferation and survival
AKT and related genes AKT pathway Increased cell growth, proliferation and survival
NF-κB related genes NF-κB pathway Increased cell proliferation
PDGFRA PDGF pathway Increased cell proliferation and survival
NOTCH1 NOTCH1 pathway Increased cell proliferation
AURKA 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
