Abstract
Extranodal natural killer/T-cell lymphoma (ENKTL) with hepatosplenic involvement is rare, accounting for approximately 0.2% of ENKTL cases. The clinicopathologic features of ENKTL with hepatosplenic involvement are still poorly understood. Seven cases of ENKTL with hepatosplenic involvement were investigated retrospectively by clinical features, pathology, immunophenotype, genotype, Epstein-Barr virus (EBV) status, and survival analysis. The median age was 36 years; three patients (3/7) had a history of primary nasal ENKTL. Six cases (6/7) presented liver or spleen structures that were replaced by neoplasms, and the neoplastic cells displayed diffuse infiltration; one case (1/7) displayed neoplastic cells scattered in hepatic sinuses and portal areas. The cellular morphology and immunohistochemical features were similar to those of ENKTL involving other sites. Follow-up data were available in five of the seven patients. All five patients received first-line chemotherapy based on L-asparaginase. Three patients died, and two were still alive by the last follow-up. The median overall survival (OS) was 21 months. ENKTL with hepatosplenic involvement is rare, regardless of whether it is initial or secondary. There are two histopathologic patterns of ENKTL with hepatosplenic involvement, and L-asparaginase-based chemotherapy combined with AHSCT might yield good efficacy. Morphological features of ENKTL in the spleen and liver A The architecture of the spleen was affected, and dense infiltration of the neoplastic cells was observed in the left part; B Focal infiltration of the neoplastic cells was located in the red pulp; C Dense infiltration of the neoplastic cells in the liver, accompanied by fatty change of hepatocytes and congestion; D More neoplastic cells accumulated in sinusoidal region.

Abstract
Cutaneous lymphomas encompass a heterogeneous group of neoplasms with a wide spectrum of clinical presentations, histopathologic features, and prognosis. Because there are overlapping pathologic features among indolent and aggressive forms and with systemic lymphomas that involve the skin, clinicopathologic correlation is essential. Herein, the clinical and histopathologic features of aggressive cutaneous B- and T-cell lymphomas are reviewed. Indolent cutaneous lymphomas/lymphoproliferative disorders, systemic lymphomas, and reactive processes that may mimic these entities are also discussed. This article highlights distinctive clinical and histopathologic features, increases awareness of rare entities, and presents new and evolving developments in the field.

Abstract
Background Extranodal NK/T-cell lymphoma of the breast (ENKTL-Breast) is rarely detected in clinical practice, and its clinicopathological features remain unclear. Results A consecutive 11-year (2010–2020) ENKTL-Breast case series was retrospectively analyzed. Eight cases of ENKTL-Breast were selected, with three primary and five secondary lesions, accounting for 3.5% (8/228) of all breast lymphomas. All patients were female with a median age of 46 years. Lesions presented as solid breast masses (8/8, 100%) and were usually located in the upper outer quadrant of the breast (7/8, 87.5%). B-symptoms were observed in seven (7/8, 87.5%) cases. Two primary ENKTL-Breast cases showed concomitant diseases (IgA nephropathy and chronic active hepatitis B). Histological and immunohistochemical features of ENKTL-Breast were similar to those of ENKTL at other sites. T-cell receptor rearrangement revealed clonality in all examined primary cases (2/2, 100%), but only in one secondary case (1/5, 20%). The disease progressed rapidly in two primary cases and both patients died within 3 and 9 months. For secondary cases, the disease manifested as a disseminated disease, with a median survival time of 6 months. Conclusions Our data suggested that ENKTL-Breast clinically mimics breast cancer to some extent, though B-symptoms might serve as a distinguishing factor. ENKTL-Breast is highly aggressive and patients with this disease exhibit a short survival time. Primary ENKTL-Breast tends to originate from activated cytotoxic T-cells, and immune-related diseases may be involved in its pathogenesis and development.

Abstract
Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL-NT), is a rare subtype of non-Hodgkin lymphoma associated with Epstein-Barr virus. This type of lymphoma is rare in Western countries but is more frequent in East Asia and Latin America. ENKTL-NT mostly occurs in the nose and paranasal area, including the upper aerodigestive tract. The skin is the second-most commonly involved organ. ENKTL-ET is characterized by an angiocentric, angiodestructive pattern of growth with ulceration and necrosis evident on histopathological examination. We provide the first description of ENKTL-NT presenting with intravascular localization of tumor cells in skin biopsies from both plaque and normal-appearing skin. Random skin biopsy might thus be useful for early diagnosis, staging, and estimation of prognosis in ENKTL-NT. Moreover, the current case indicates that ENKTL-NT and intravascular natural killer/T-cell lymphoma may represent related diseases.

Abstract
BACKGROUND Intestinal T-cell and NK/T- cell lymphomas are rare and aggressive. The diagnosis is quite difficult, especial in biopsy specimens. This study investigates the clinicopathological features of intestinal T-cell and NK/T-cell lymphomas to aid their differential diagnosis. METHODS Clinical data of 27 cases were collected. Including extranodal NK/T-cell lymphoma, nasal type (ENKTCL-N), monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS), anaplastic large-cell lymphoma, ALK+ (ALCL, ALK+) and angioimmunoblastic T-cell lymphoma (AITL). The histologic features, immunohistochemical findings, T-cell receptor gene rearrangement results, and follow-up data were analyzed, with review of literature. RESULTS The age of the patients (N = 27) was 15-85 years (mean, 47.5 years), and male:female ratio, 3.5:1. Abdominal pain and B symptoms were the most common symptoms. Although 85.2% of the patients were in clinical stage I-II, 59.3% died within 1 year. MEITL showed certain distinctive clinic opathological features from ENKTCL-N. Compared to lesions at other sites, there were no differences in the morphological features, immunophenotype and TCR gene rearrangement of intestinal ENKTCL-N, PTCL, NOS, ALCL, ALK+ and AITL. CONCLUSION Intestinal T-cell and NK/T-cell lymphomas are a heterogeneous group of lymphomas. They could be classified to 5 histological subtypes in our study. ENKTCL-N and MEITL formed the majority of the tumor types. Each subtype has distinctive pathological features, but most of them have diamal prognosis.

Abstract
Hydroa vacciniforme-like lymphoproliferative disorder (HVLPD) is defined as a distinctive clinicopathological type of cutaneous lymphoma and a subset of patients with this disease exhibit the natural killer (NK)-cell phenotype. The HVLPD-NK cell phenotype may be difficult to distinguish from cutaneous natural killer T-cell lymphoma (CNKTL), as these two diseases share similar immunophenotypic markers. Therefore, the aim of the present study was to analyze the clinicopathological features of this rare disease and compare these features with those of CNKTL. The clinical, histopathological and molecular features of 5 patients with the HVLPD-NK cell phenotype and 11 patients with CNKTL were evaluated. As well as certain subtle histopathological differences, there marked differences the age, distribution of lesions and clinical course differed between patients with these two diseases. These results suggest that the HVLPD-NK cell phenotype should be classified as a separate disorder and treated accordingly.

Abstract
INTRODUCTION The distribution of extranodal NK/T-cell lymphoma (ENKTCL) is highly inhomogeneous throughout the world. In Sub-Saharan Africa, despite the precocity of Epstein-Barr virus (EBV) infection and its endemicity, ENKTCL remains exceptionally reported. The purpose of this study was to report the epidemiological, clinical, paraclinical, and evolutionary characteristics of ENKTCL at the Aristide LeDantec University Hospital in Dakar, Senegal. METHODOLOGY A 5-year retrospective review of all patients with histopathological, immunohistochemical, and in situ hybridization proven cutaneous lymphomas RESULTS: We collected seven cases corresponding to a frequency of 1.4 cases per year. ENKTCL accounted for 10.5% of all cutaneous lymphomas, ranking second after T-cell lymphomas. Men were predominantly affected (M : F ratio of 6), and the mean age was 38.5 years ± 4.06. The mean time before consultation was 7.3 months. The lymphomas affected primarily the nasal cavity in five cases and the skin in two cases. At admission, six patients had nasal mucosa involvement, which was isolated in three cases, associated with cutaneous lesions in three cases and lymph node involvement in three cases. CD56 was positive in only one case, and Eber transcribed RNA of EBV was expressed by in situ hybridization in all patients. DISCUSSION To our knowledge, we have reported the first and largest series of ENKTCL in Sub-Saharan Africa. Our study shows an intermediate prevalence between that reported from Asia, Latin America, and the West. It was also noted a young age of patients, a prolonged diagnostic delay, a frequent negativity of CD56 marker, and a very poor prognosis of the disease in our region.

Abstract
OBJECTIVE To evaluate the use of fluorine-18 fluorodeoxyglucose (F-FDG) PET/computed tomography (CT) in the diagnosis of cutaneous extranodal natural killer/T-cell lymphoma, nasal type (C-ENK/T-NT). METHODS A total of 39 patients with newly diagnosed C-ENK/T-NT were enrolled between May 2006 and November 2013. Anatomic regions (n=429; five cutaneous and six extracutaneous regions per patient) were assessed using an F-FDG PET/CT scan and conventional staging methods (CSMs). F-FDG PET/CT and CSMs were compared and evaluated for their ability to detect tumor lesions and their influence on the staging and treatment strategies. Biopsy and clinical follow-up were used as the gold standard for diagnosis. RESULTS In total, 139 lesions were detected by CSMs and F-FDG PET/CT, of which there were 50 cutaneous and 89 extracutaneous-positive regions. F-FDG PET/CT detected 48 cutaneous and 88 extracutaneous regions. CSMs, however, detected only 34 cutaneous lesions and 61 extracutaneous lesions that were positive for malignancy (cutaneous comparison of PET/CT vs. CSMs, P<0.001; extracutaneous comparison of PET/CT vs. CSMs, P<0.05). Using F-FDG PET/CT, 8 (42%) patients were in stage I-II and 31 patients (58%) were in stage III-IV. F-FDG PET/CT staging was consistent with the final stage determination in 94.9% (37/39) of patients, whereas CSMs staging was correct in final stage determination in 74.4% (29/39) of patients (P=0.025). CONCLUSION Our study showed that F-FDG PET/CT scanning is a valuable modality for the detection of cutaneous and extracutaneous lesions of C-ENK/T-NT. F-FDG PET/CT may therefore influence future staging and treatment strategies.

Abstract
Angioinvasion/angiodestruction has been reported in a small subset of primary cutaneous anaplastic large-cell lymphomas (PCALCL). Recently, PCALCL with angioinvasive features and cytotoxic phenotype has been characterized as a variant associated with good clinical outcomes despite worrisome histopathologic features. We report a case of PCALCL with angioinvasive features and cytotoxic phenotype associated with reparative changes on the wall of medium-sized vessels involved by the neoplasm, including intimal fibroblastic proliferation and luminal obliteration. This vascular pattern, although previously unreported in PCALCL, is in accordance with the indolent behavior observed in this entity and provides a further link with lymphomatoid papulosis type E.

Abstract
Epstein-Barr virus (EBV) was the first human virus to be associated with oncogenesis. Over the past few decades, cumulative research has revealed that latent EBV infection may be implicated in the pathogenesis of a heterogeneous group of lymphoproliferative disorders and malignancies occurring in both immunocompetent and immunocompromised hosts. Many of these diseases have either primary or secondary cutaneous manifestations. Serologic studies and EBV-encoded RNA in situ hybridization stains have been used to show the association of EBV with disease; while these findings may imply a role, they do not equate with causation. In part II of this continuing medical education review, the salient features of EBV-associated lymphoproliferative disorders and solid tumors are detailed.

Abstract
The cytotoxic T-cell and natural killer (NK)-cell lymphomas and related disorders are important but relatively rare lymphoid neoplasms that frequently are a challenge for practicing pathologists. This selective review, based on a meeting of the International Lymphoma Study Group, briefly reviews T-cell and NK-cell development and addresses questions related to the importance of precise cell lineage (αβ-type T cell, γδ T cell, or NK cell), the implications of Epstein-Barr virus infection, the significance of anatomic location including nodal disease, and the question of further categorization of enteropathy-associated T-cell lymphomas. Finally, developments subsequent to the 2008 World Health Organization Classification, including the recognition of indolent NK-cell and T-cell disorders of the gastrointestinal tract are presented.

[PMID: 25213430 DOI: 10.1016/j.humpath.2014.04.024] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2014] [Revised: 04/21/2014] [Accepted: 04/24/2014] [Indexed: 02/05/2023]
Abstract
To analyze the differentiation characteristics of extranodal natural killer/T-cell lymphoma, nasal type, one nude mouse model, cell lines SNK6 and SNT8, and 16 fresh human samples were analyzed by flow cytometry immunophenotyping and immunohistochemistry staining; and 115 archived cases were used for phenotypic detection and prognostic analysis. We found that CD25 was expressed by most tumor cells in all samples, and CD56(+)CD25(+) cells were the predominant population in the mouse model, the 2 cell lines, and 10 of the 16 fresh tumor samples; in the other 6 fresh tumor samples, the predominant cell population was of the CD16(+)CD25(+) phenotype, and only a minor population showed the CD56(+)CD25(+) phenotype. The phenotype detected by immunohistochemistry staining generally was consistent with the phenotype found by flow cytometry immunophenotyping. According to the expression of CD56 and CD16, 115 cases could be classified into 3 phenotypic subtypes: CD56(-)CD16(-), CD56(+)CD16(-), and CD56(dim/-)CD16(+). Patients with tumors of the CD56(dim/-)CD16(+) phenotype had a poorer prognosis than patients with tumors of the other phenotypes. Differentiation of extranodal natural killer/T-cell lymphoma, nasal type apparently resembles the normal natural killer cell developmental pattern, and these tumors can be classified into 3 phenotypic subtypes of different aggressiveness. Expression of CD56(dim/-)CD16(+) implies a poorer prognosis.

Cutaneous extranodal natural killer/T-cell lymphoma: a comparative clinicohistopathologic and survival outcome analysis of 45 cases according to the primary tumor site. J Am Acad Dermatol 2014; 70:1002-9. [PMID: 24629518 DOI: 10.1016/j.jaad.2013.12.023] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2013] [Revised: 12/17/2013] [Accepted: 12/19/2013] [Indexed: 11/22/2022]
Abstract
BACKGROUND Differences in survival outcomes and prognostic factors of cutaneous extranodal natural killer/T-cell lymphoma (ENKTL) depending on primary tumor site are currently unknown. OBJECTIVE We sought to analyze the clinicopathological features and survival outcomes of cutaneous ENKTL according to primary tumor site. METHODS In all, 45 patients with cutaneous ENKTL were classified with: (1) primary cutaneous ENKTL, or (2) nasal ENKTL with cutaneous involvement. Clinicopathologic features, survival outcomes, and prognostic factors were analyzed using patient's medical records. Survival outcomes were analyzed using the Kaplan-Meier method and compared using the log rank test. The Student t test, Fisher exact test, and linear by linear association test were used to analyze clinicopathologic differences between groups. RESULTS Clinical manifestations of cutaneous ENKTL included solitary or multiple subcutaneous nodules and cellulitis or abscess-like lesions. Primary cutaneous ENKTL demonstrated a less aggressive clinical course and better survival outcomes. The extent of cutaneous lesions demonstrated a significant effect on the prognosis of primary cutaneous ENKTL, but not on nasal ENKTL with cutaneous involvement. The presence of nasal lesions in primary cutaneous ENKTL was associated with poor prognosis. LIMITATIONS This study used a retrospective design and included a small sample size. CONCLUSION Although the clinicopathological features were similar regardless of subgroup, survival outcomes and prognostic factors differed depending on the primary tumor site of cutaneous ENKTL.

Abstract
A 35-year-old Chinese woman presented with a 2.5-year history of facial swelling in the left lower quadrant and a 10-month history of relapsing red papules and vesicles in the perioral area resembling hydroa vacciniforme. Histologically, a tissue biopsy showed a dense infiltration of medium-sized atypical lymphocytic cells expressing CD4 and CD56. A diagnosis of cutaneous NK-/T-cell lymphoma was made. The patient was treated with alpha-interferon, valaciclovir hydrochloride, and low-dose prednisone for 2 months. Her skin lesions and lymphoadenopathy resolved initially, but she succumbed to the disease shortly after starting chemotherapy treatment 11 months later. To our knowledge, this is the first case of CD4CD56 NK-/T-cell lymphoma with clinical features resembling hydroa vacciniforme.

Abstract
Virtual slides The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/7644172219178472 Hydroa vacciniforme-like lymphoma (HVL) is a rare type of Epstein-Barr virus (EBV)-positive lymphoma of cytotoxic T-cell or natural killer cell origin that mainly affect children, characterized by a vesicopapular skin eruption that clinically resemble hydroa vacciniforme (HV). In current study, we report an adult patient with the tumor. The patient presented similar morphologic, immunophenotypic and genotypic changes of the disease with that occurred in children, whereas clinically, he showed a prolonged clinical course without hepatosplenomegaly or generalized lymphadenopathy. Whether there are some differences in biologic behavior between children and adults still remains unknown and it is necessary to collect more data to observe and to investigate in the future.

Abstract
Extranodal NK/T-cell lymphoma (ENKTL), nasal type, may be of NK or T-cell origin; however, the proportion of T-ENKTLs and whether they are of αβ or γδ type remains uncertain. To elucidate the cell of origin and detailed phenotype of ENKTL and assess any clinicopathologic associations, 67 cases of ENKTL from Thailand were investigated, together with 5 γδ enteropathy-associated T-cell lymphomas (EATLs) for comparison. In all, 70% of the ENKTL were T-cell receptor (TCR) β,γ and, in cases tested, δ negative (presumptive NK origin); 5% were TCR γδ, 3% were TCR αβ, 1% were TCR αβ/γδ, and 21% were indeterminate. Out of 17 presumptive NK-ENKTLs tested, 3 had clonal TCR rearrangements. All cases were EBV and TIA-1; >85% were positive for CD3, CD2, granzyme B, pSTAT3, and Lsk/MATK; and all were CD16. Presumptive NK-ENKTLs had significantly more frequent CD56 (83% vs. 33%) and CXCL13 (59% vs. 0%) but less frequent PD-1 (0% vs. 40%) compared with T-ENKTLs. Of the NK-ENKTLs, 38% were Oct-2 compared with 0% of T-ENKTLs, and 54% were IRF4/MUM1 compared with 20% of T-ENKTLs. Only αβ T-ENKTLs were CD5. Intestinal ENKTLs were EBV and had significantly more frequent CD30, pSTAT3, and IRF4/MUM1 expression but less frequent CD16 compared with γδ EATL. Significant adverse prognostic indicators included a primary non-upper aerodigestive tract site, high stage, bone marrow involvement, International Prognostic Index ≥2, lack of radiotherapy, Ki67 >40%, and CD25 expression. The upper aerodigestive tract ENKTLs of T-cell origin compared with those of presumptive NK origin showed a trend for better survival. Thus, at least 11% of evaluable ENKTLs are of T-cell origin. Although T-ENKTLs have phenotypic and some possible clinical differences, they share many similarities with ENKTLs that lack TCR expression and are distinct from intestinal γδ EATL.

Abstract
This study determined the clinical characteristics and prognosis for patients with extranodal nasal-type natural killer/T-cell lymphoma (NKTCL) with secondary cutaneous involvement. Twenty-eight patients with NKTCL of the upper aerodigestive tract with secondary cutaneous involvement were reviewed. The median overall survival (OS) was 21.5 months from the first diagnosis, and 12.3 months from the presentation of a cutaneous lesion. The 5-year OS rate was 43.1% (median, 28 months) for patients with localized cutaneous disease compared with 0% (median, 3.6 months) for generalized cutaneous disease (p = 0.017). The 2-year OS rates were 67.5% for patients who achieved a complete response (CR) compared with 19.4% (median, 5.2 months) for patients who did not (p = 0.003). Patients with NKTCL with secondary cutaneous dissemination overall have a poor prognosis, but a relatively favorable prognosis was identified for the small subgroup of patients who had localized cutaneous lesions and achieved a CR.

Abstract
Natural killer (NK)-cell malignancies are uncommon neoplasms, which have been referred to as polymorphic reticulosis or angiocentric T-cell lymphomas in the past. In the current WHO classification, they are categorized as extranodal NK/T-cell lymphoma, nasal type and aggressive NK-cell leukemia. NK-cell malignancies show a geographical predilection for Asian and South American populations and are rare in the west. Pathologically, NK-cell lymphomas show a polymorphic neoplastic infiltrate with angioinvasion and angiodestruction. The lymphoma cells are CD2(+), cytoplasmic CD3ε(+) and CD56(+), with germline T-cell receptor gene. There is an almost invariable clonal episomal infection with Epstein-Barr virus. Clinically, NK-cell lymphomas can be classified into nasal, non-nasal and aggressive lymphoma/leukemia subtypes. Most nasal NK-cell lymphomas present with stage I/II disease. The early use of radiotherapy, either alone or concomitantly/sequentially with chemotherapy, is the most important factor in achieving successful treatment. Many stage I/II patients receiving radiotherapy alone fail systemically, so the use of chemotherapy is also considered necessary. Chemotherapy is indicated for stage III/IV nasal NK-cell lymphoma, and the non-nasal and aggressive subtypes. Recent regimens that incorporate the use of L-asparaginase have resulted in substantial improvements in outcome in high-risk, refractory or relapsed patients. High-dose chemotherapy and hematopoietic stem-cell transplantation with autologous or allogeneic hematopoietic stem cells may be beneficial to selected patients. Prognostication of patients with clinical prognostic models and presentation circulating Epstein-Barr DNA load may be useful in the stratification of patients for various treatment modalities.

Abstract
Hydroa vacciniforme-like cutaneous lymphoma is a rare type of Epstein-Barr virus-associated lymphoma. We analyze clinicopathologic features of seven Chinese child patients with hydroa vacciniforme-like cutaneous lymphoma and determine the pathogenic association of Epstein-Barr virus with this disorder. Clinical, histologic, and immunohistochemical features were reviewed. Skin lesions were subjected to Epstein-Barr virus-encoded RNA detection by in situ hybridization. Serologic assay and quantitation of Epstein-Barr virus DNA were performed. All seven patients presented with facial vesicles, papulovesicles, and atrophic scarring. Histologically, skin specimens showed epidermal blister formation, and dense lymphoid infiltration throughout the dermis and subcutaneous tissue. The infiltrate was composed of both small and large irregular lymphocytic cells expressing CD45RO or CD56. Tumor cells positive for Epstein-Barr virus-encoded RNA were detected in cutaneous infiltrates in all seven cases. Besides skin eruptions, all patients had systemic manifestations, such as intermittent fever, hepatosplenomegaly or lymph node enlargement. The amounts of Epstein-Barr virus DNA were increased in the peripheral blood in two detected cases, and antibody titers to Epstein-Barr virus revealed a chronic active Epstein-Barr virus infection in all cases. The diagnosis of hydroa vacciniforme-like cutaneous lymphoma was made. Four of seven patients were treated with interferon α intramuscularly, and the skin eruptions improved. Hydroa vacciniforme-like cutaneous lymphoma may present with severe facial edema, papulovesicular eruptions and permanent scars. The tumor cells often express natural killer- or T-cell markers. The disease is often preceded by chronic active Epstein-Barr virus infection.

Abstract
Extranodal natural killer/T-cell (ENK/T) lymphoma is a rare neoplasm, subcategorized into ENK/T-nasal (ENK/T-N) and ENK/T-nasal type (ENK/T-NT) lymphomas. ENK/T-NT lymphoma with initial presentation in the skin is known as primary cutaneous ENK/T-NT (PC-ENK/T-NT) lymphoma. The aim of this study was to investigate pathogenesis, genomic alterations, and prognosis of cutaneous ENK/T lymphomas to provide further insights into clinicopathologic features and genetic mechanism of lymphomagenesis. A retrospective case study of 5 white patients affected by ENK/T lymphoma (4 PC-ENK/T-NT and 1 ENK/T-N with cutaneous involvement) was performed. Most of the cases presented with multiple nodules and ulcerations localized on the extremities. A considerable percentage had disease in advanced stage with a 12-month survival rate of 40%. Genomic alterations were detected by array-based comparative genomic hybridization that showed gains of 1q, 7q and loss of 17p in the cases of PC-ENK/T-NT lymphomas and gain of 7q and loss of 9p, 12p, 12q in the case of ENK/T-N lymphoma. In conclusion, ENK/T lymphoma is a very aggressive entity, and, in our cases, the exclusively cutaneous presentation was not associated with a better prognosis. The results of our array comparative genomic hybridization analysis could be useful to better define the different ENK/T lymphoma subgroups with cutaneous involvement.

Abstract
Extranodal natural killer (NK) cell/T-cell lymphoma, nasal type, is a rare aggressive neoplasm, most commonly presenting as a destructive lesion in the nasal cavity and nasopharynx in middle-aged to older adults. About one third of cases present in an extranasal location, commonly involving skin and gastrointestinal tract, and usually occur in the absence of superficial lymphadenopathy. Diagnosis of this malignancy can be missed given its rarity and heterogeneous presentation. We describe a patient with an extranodal NK cell/T-cell lymphoma, nasal type, who was initially diagnosed and treated for a presumed Mycobacterium marinum infection, after biopsies were unrevealing. However, after more serious complications developed, repeat biopsy was performed. An atypical lymphocytic infiltrate was noted, with cells being positive for NK cell/T-cell markers CD2, CD7, and CD3 (subset), as well as for cytotoxic lymphocyte markers perforin, T-cell intracellular antigen, and CD56. In situ hybridization for Epstein-Barr virus-encoded RNA was also positive. This case demonstrates an important diagnostic pitfall of confusing cutaneous involvement by an aggressive NK cell/T-cell lymphoma with an antibiotic-resistant infection. Repeat biopsies and close clinicopathologic correlation are essential for establishment of correct diagnosis.
