Herein, we report a case of nasal natural killer T-cell lymphoma (NKTL) with intraocular involvement. A 57-year-old woman was referred due to a three-day history of photophobia and diplopia in the left eye. One-month previously, she was diagnosed with nasal NKTL of the right nasal cavity. Ophthalmic examination revealed conjunctival injection and ptosis. The left pupil was fully dilated and non-reactive to light. Ocular motion was restricted on left-upper gaze. Five days later, anterior uveitis developed and persisted despite topical steroid treatment. An orbital magnetic resonance imaging was without specific findings, however, ophthalmoplegia, vitreous opacity, and an iris mass were observed. A diagnostic anterior chamber aspiration was performed. Aqueous humor aspiration revealed 35% morphologically atypical lymphocytes. After an intravitreal triamcinolone injection, radiotherapy and chemotherapy were administered; this resolved the uveitis and iris mass. When refractory uveitis or orbital pseudotumor occurs in patients with nasal NKTL, ocular and orbital involvement of the NKTL should be considered.
Purpose To describe the clinical, morphologic, and immunohistochemical features of a case of paranasal natural killer/T-cell lymphoma (NKTL) with ocular involvement. Case report In March 2005 the patient presented with a maxillary sinusitis and upper nasal obstruction. In July she underwent a nasal computed tomography (CT) scan and multiple biopsies of the granulomatous tissue in the nasal fossae. The diagnosis was NK/T non-Hodgkin’s lymphoma nasal type, stage IV A. Afterwards she presented ante...

Extranodal NK/T-cell lymphoma, nasal type (ENKTCL), previously known as lethal midline granuloma is a distinct clinico-pathological entity associated with Epstein-Barr virus that typically causes destruction of the midface, palatal and orbital walls. In addition, ENKTCL can involve the skin, soft tissue, testes, gastrointestinal and upper respiratory tract. ENKTCL neoplastic cells express some T-cell associated antigens, most commonly CD2 and cytoplasmic CD3e and, in favour of an NK-cell origin,...
Purpose To review the clinical, radiological, and histopathologic features in 8 patients with natural killer/T-cell lymphoma (NKTL) involving the orbit and/or ocular adnexa, and to describe the responses of these patients to various treatment regimens. Design Retrospective observational case series. Participants Eight patients (5 male, 3 female) with NKTL involving the orbit and/or ocular adnexa were identified from 1999 through 2005. The mean age at presentation was 45 years (range, 26–65). Met...
Purpose: To report two cases of nasal type Natural Killer (NK)/T-cell lymphoma of the orbit. Methods: (Case 1) A 42-year-old woman presented with a 3-month history of painful proptosis and eyelid swelling in the right eye. Under the diagnosis of inflammatory pseudotumor, she was treated with intravenous and oral steroids. She visited our clinic with a 3-day history of proptosis with decreased visual acuity. Computed tomography (CT) revealed a large infiltrative mass in the right orbit. Incisiona...
Abstract PURPOSE: Nasal T/NK lineage lymphoma, previously known as lethal midline granuloma, is common among Oriental, Native-American, and Hispanic patients and is invariably associated with Epstein-Barr virus. Nasal localization, local necrosis, angioinvasion, and aggressive behavior are hallmarks of the disease. Ophthalmologic symptoms and signs may precede lymphoma diagnosis or complicate its disease course. We aim to define the incidence and disease pattern of ophthalmic involvement. DESIGN...

Abstract Objective Lymphoproliferative lesions of the ocular adnexa were analyzed to examine (1) the suitability of the Revised European-American Lymphoma (REAL) classification for the subtyping of the lymphomas in these sites; (2) the predictive value of the REAL classification for the evolution of these tumors; and (3) the frequency and prognostic impact of tumor type, location, proliferation rate (Ki-67 index), p53, and CD5 positivity and the presence of monoclonality within these tumors. Des...
Neoplasms of natural killer (NK) cells are a group of uncommon but highly aggressive malignancies with a strong geographic predilection, and predominantly involving extranodal sites, particularly the nasal/nasopharyngeal region, and sometimes extranasal areas such as the skin and gastrointestinal tract. This group of tumors is characterized: 1) pathologically by an angiocentric and angiodestructive infiltrate of lymphoid cells that can span a broad cytologic spectrum, and that frequently contain...
PURPOSETo study the clinical features and outcome for primary non-Hodgkin's lymphomas of the nose/nasopharynx (NNP-NHLs) according to immunophenotype.PATIENTS AND METHODSOne hundred thirteen Chinese patients with primary NNP-NHLs that belonged to the categories E, F, G, or H according to the Working Formulation (WF), with full immunophenotypic data and complete clinical follow-up data, were analyzed in this retrospective study.RESULTSNinety (79.6%) patients had localized (stage I or II) disease,...
Expression of the natural killer (NK) cell antigen CD56 is uncommon among lymphomas, and those that do are almost exclusively of non–B-cell lineage and show a predilection for the nasal and nasopharyngeal region. This study analyzes 49 cases of nonnasal CD56+ lymphomas, the largest series to date, to characterize the clinicopathologic spectrum of these rare neoplasms. All patients were Chinese. Four categories could be delineated. (1) Nasal-type NK/T cell lymphoma (n = 34) patients were adults 2...
Introduction null Natural killer (NK) cell lymphoma is a progressive non-Hodgkin's lymphoma with rare prevalence. Intraocular involvement of NK cell lymphoma is very rare, with only case reports to date. null Case presentation null Here, we report a case of intraocular involvement of NK cell lymphoma which was presented with bilateral uveitis, iris mass, and diffuse infiltration into the center nerve system (CNS), skin, and possibly myocardium. null Conclusions null Iris mass and uveitis which i...

Floaters or visual disturbance in a patient with ENKL should prompt evaluation for possible vitreoretinal involvement. Lymphoma with ocular involvement should be treated aggressively and in most cases heralds CNS involvement.
Abstract Aim This study explored the clinical features of nasal natural killer/T-cell lymphoma (NKTL) in patients with prominent ocular symptoms and those with general nasal NKTL to improve the early diagnosis of nasal NKTL. Method A retrospective cohort study was performed with 278 patients with nasal NKTL admitted to the First Affiliated Hospital of Zhengzhou University between January 2011 and December 2017. Of these cases, 56 presented with nasal NKTL and prominent ocular symptoms, and 222 p...

Background Intraocular involvement of systemic T-cell lymphomas are uncommon and have been broadly regarded as markers of poor prognosis. We reported two cases of uveitis patients finally diagnosed as systemic T cell lymphoma.
INTRODUCTION: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. CASE REPORT: The present study examines a case of NKTCL in a 23-year-old man with a destructive ulcer of the palate and uvulae. Based on immunohistoche...
: Extranodal natural killer/T-cell lymphoma (ENK/TCL) is most often in the nose or the nasopharynx but can present elsewhere. We report a rare case of ENK/TCL that presented as swelling of an upper eyelid without ocular involvement. A 76-year-old man visited our hospital with a swollen lesion of the left upper eyelid which had appeared 2 months earlier. A biopsy of the upper eyelid revealed slight perivascular and periadnexal infiltration of mononuclear cells with dermal edema. Treatment with or...

Uveitis is an autoimmune disease of the eye that refers to a number of intraocular inflammatory conditions. We identified three rare cases of T cell lymphoma diagnosed following an initial presentation of uveitis. This study summarized the clinical features of these rare cases and evaluated the association between uveitis and lymphoma. We analyzed the etiology of uveitis diagnosed in the Department of Pediatrics and Internal Medicine at our hospital. Five patients were diagnosed with uveitis and...
