Clinical characteristics and treatment outcomes of natural killer/T-cell lymphoma involving the ocular adnexa

A Case Report of Extranodal NK/T-Cell Lymphoma Misdiagnosed as Meibomitis

INTRODUCTION

Extranodal natural killer/T-cell lymphoma (ENKTL) is a rare type of non-Hodgkin's lymphoma. This report presents a patient with the right lower eyelid ENKTL misdiagnosed as meibomitis repeatedly.

CASE PRESENTATION

A 48-year-old woman developed recurrent redness and swelling in right eyelid for 2 years. Three eyelid mass removal operations were performed in local hospitals, and the pathological examination suggested meibomitis. Physical examination showed an induration in the lateral lower eyelid of the right eye, local defect of the eyelid margin, mild entropion, redness and swelling of the surrounding tissues, and temporal bulbar conjunctiva hyperemia. The eyelid lesion was resected and ENKTL was diagnosed by specific immunohistochemical staining and in situ hybridization. The lymphoma resolved with chemotherapy and radiotherapy. The patient was still alive forty-one months after the last operation.

CONCLUSION

Our report demonstrates that recurrent eyelid redness and swelling might be a malignant tumor, and clinicians should be vigilant.

Anaplastic Large Cell Lymphoma With Intraocular or Ocular Adnexal Involvement: A Case Report and Systematic Review

PURPOSE

To review the existing literature on patients with anaplastic large cell lymphoma (ALCL) affecting the globe and/or ocular adnexa, and to present a report documenting the clinical course of a patient with ALCL that involved their globe and ocular adnexa.

METHODS

PubMed, Scopus, and Google scholar were systematically searched for all cases of ALCL involving intraocular or adnexal ocular structures from inception to May 2023. Moreover, a new reported case added to the cases found in searches.

RESULTS

The review identified 1680 studies, with 8 meeting inclusion criteria. A total of 9 patients were included with a mean age of 29.7 years (median: 30.0, range: 1.3-48). Primary ALCL was present in 5/9 (55.6%) patients. The most common ophthalmic manifestations included periorbital swelling (5/8), chemosis (5.8), and decreased vision (5/7). Misdiagnoses were initially made in 3 patients, and the lag time to correct diagnosis from 3 weeks to 3 months. CD30 expression was positive in all cases, and 6/9 patients were positive for anaplastic lymphoma kinase, resulting in 6/9 patients being diagnosed with anaplastic lymphoma kinase-positive ALCL. In terms of management modalities, chemotherapy was administered in 8/9 patients, while radiation therapy was utilized in 4/9 patients, and 2 underwent autologous stem cell transplantation. Five (55.6%) patients succumbed to ALCL while 4 (44.4%) were alive and disease-free at the last follow-up. The median times from the initial presentation of ALCL to death, ophthalmic presentation to death, and diagnosis to death were 4.12 months (range: 1.1-168.0), 2.62 months (range: 1.1-144), and 4.00 months (range: 0.10-168), respectively. The median follow-up duration was 21.0 months (range: 1.1-168.0).

CONCLUSIONS

ALCL involving the globe and ocular adnexa is a rare and highly malignant tumor that can mimic benign clinical conditions. Early biopsy and aggressive treatment with chemotherapy regimens such as CHOP and radiation therapy may be useful.

Primary ophthalmic natural killer/T-cell lymphoma: A population-based study

BACKGROUND

Ophthalmic lymphomas, a subgroup of extra-nodal lymphomas, have seen an increase in incidence in recent decades. Of these, the NK/T-cell lymphoma (NKTL) subtype is particularly aggressive. Though prevalent mostly in Asian patients, data on ophthalmic NKTL is still limited, especially in the western population. This study aimed to provide an additional analysis of primary ophthalmic NKTL using the Surveillance, Epidemiology, and End Results (SEER) database.

METHODS

A retrospective analysis was performed on the SEER database covering records from 2000 to 2020. Patients diagnosed with extranodal NKTL originating primarily from an ophthalmic structure were identified.

RESULTS

Out of 4540 ophthalmic lymphomas registered in the SEER database between 2000 and 2020, 9 cases (0.2%) corresponded to ophthalmic NKTL, occurring in patients with a median age of 67 years. The majority of these patients underwent chemotherapy (88.8%) and radiotherapy (66.6%). The 6-month overall survival (OS) and cancer-specific survival (CSS) were both at 50.8%, dropping significantly at the 2-year follow-up.

CONCLUSION

Primary orbital NKTL has a notably severe prognosis. An early diagnosis is important due to the aggressive nature of NKTL.

NK/T-cell Lymphoma With Orbital Involvement: A Case Report and Systematic Review of the Literature

PURPOSE

To present the clinical course of a patient with recurrent NK/T-cell lymphoma (NKTL) involving the orbit and to review the literature on patients with NKTL involving the orbit.

METHODS

The PubMed database was searched for all cases of NKTL involving orbital, intraocular, or adnexal ocular structures.

RESULTS

Ninety-six patients were included in the final analysis. The mean age of diagnosis was 48.1 ± 16.8 years. The patients were 53/96 (55.2%) male and 43/96 (44.8%) female. Tumor location varied and included the orbit in 80/96 (83.3%), nasosinus in 56/96 (58.3%), uvea in 11/96 (11.5%), lacrimal gland in 9/96 (9.4%), lacrimal drainage system in 11/96 (11.5%), and conjunctiva in 7/96 (7.3%) cases. Management included surgical debulking in 29/96 (30.2%) cases, radiotherapy in 52/96 (54.2%) cases, and chemotherapy in 82/96 (85.4%) cases. Median survival was 6 months (95% CI: 5-9). Chemotherapy (hazard ratio = 0.80, 95% CI: 0.67-0.95, p = 0.013), radiotherapy (hazard ratio = 0.75, 95% CI: 0.64-0.87, p < 0.001), and orbital involvement being a recurrence of disease (hazard ratio = 0.79, 95% CI: 0.67-0.95, p = 0.009) were associated with improved survival. Advanced Ann Arbor stage (III-IV) at diagnosis (hazard ratio = 1.22, 95% CI: 1.08-1.38, p = 0.001), vision loss (hazard ratio = 1.18, 95% CI: 1.04-1.34, p = 0.009), proptosis (hazard ratio = 1.15, 95% CI: 1.01-1.30, p = 0.035) and periorbital swelling (hazard ratio = 1.15, 95% CI: 1.00-1.33, p = 0.048) were associated with poor survival.

CONCLUSIONS

NK/T-cell lymphoma involving the orbit, globe, or ocular adnexa heralds a poor prognosis where early diagnosis and therapy are critical. The use of radiotherapy and chemotherapy is associated with improved survival.

Thirty Years of Experience With Ocular Adnexal T-Cell Lymphoma

PURPOSE

To evaluate the disease characteristics and survival of patients with ocular adnexal T-cell lymphoma.

METHODS

A retrospective, observational study of patients with a histopathological diagnosis of T-cell lymphoma of the ocular adnexa seen between 1992 and 2022. Demographic data, clinical presentation, imaging, histology, immunohistochemistry, treatment, and outcomes were reviewed.

RESULTS

Fifteen patients were included in the study with the mean age at diagnosis of 50 years old (range 7-85). The most common presenting symptoms were ulcerated eyelid skin lesions (40%) followed by eyelid swelling (13.3%), and lacrimal passageways obstruction (13.3%). The anaplastic large cell lymphoma (33%) and primary cutaneous T-cell lymphoma (33%) were the most diagnosed peripheral T-cell lymphoma subtypes, followed by the nasal type natural killer/T-cell lymphoma (27%) and peripheral T-cell lymphoma not otherwise specified (7%). The most prevalent stage of disease progression was stage I and stage IV (Ann Arbor classification) with seven (47%) patients each. Eight (53%) patients succumbed to the disease process of which three (37.5%) deceased in the first six months and six (75%) within the first year of diagnosis. We identified a strong statistical association between stage and disease-related death ( p = 0.003).

CONCLUSIONS

Peripheral T-cell lymphoma occurring in the orbit and ocular adnexa is extremely rare. Advanced stage at diagnosis leads to almost certain death from the disease despite aggressive local and systemic treatment. Early diagnosis improves the chances of survival but can be hindered by this condition's ability to simulate benign inflammatory conditions both clinically and histologically.

Clinical characteristics and treatment outcomes of secondary ocular adnexal lymphoma

BACKGROUND

To describe the clinical characteristics and treatment outcomes of secondary ocular adnexal lymphoma (OAL), and emphasise the impact of timely biopsy and systemic evaluation on the diagnosis and treatment.

METHODS

The data of patients with secondary OAL in our hospital from January 2010 to June 2021 were retrospectively reviewed.

RESULTS

A total of 54 patients (30 men and 24 women) were included in the study. The mean age at presentation was 60 years (median 62 years; range 37-83 years). The main symptoms included ocular mass (74%), periorbital swelling (43%), and proptosis (39%). The main histopathological types were mucosa-associated lymphoid tissue lymphoma (30%), diffuse large B-cell lymphoma (28%), and natural killer/T-cell lymphoma (18%). In particular, three patients exhibited different pathological types of ocular lymphoma compared to previously diagnosed systemic lymphoma. The most common site of ocular and systemic involvement was the orbit (85%) and lymph nodes (56%), respectively, and 25 (46%) patients had occult extraocular lesions. Additionally, the 5-year overall survival rate of the entire cohort was 56%, and significant differences were observed between the three main pathological types and stages of the disease (all p < 0.001).

CONCLUSIONS

Secondary OAL is a rare disease with a poor prognosis. That the disease is associated with a more aggressive pathological type is well established, indolent lymphoma is not uncommon. Furthermore, OAL and previously diagnosed systemic lymphoma may be pathologically distinct in some patients. Therefore, we recommend a prompt excision biopsy and a thorough systemic evaluation of patients with suspected OAL.

Extranodal natural killer/T-cell lymphoma nasal type with extensive ocular tissue involvement: a case report

Background

To report a rare case of extranodal natural killer/T-cell lymphoma (ENKTL), nasal type related to extensive ocular tissue, including conjunctiva, ciliary body, vitreous and retina.

Case presentation

A 52-year-old woman who had been treated by radiotherapy for ENKTL, nasal type in the right nasal cavity presented with a dramatic deterioration of vision in right eye. Physical and accessory examination showed extensive ocular tissue related, including conjunctiva, ciliary body, vitreous and retina. Vitreous specimen and conjunctiva biopsy revealed the presence of ENKTL, nasal type in the right eye. She was treated with systemic and ophthalmic chemotherapy, her ocular symptoms significantly improved, and systemic condition remained stable 7 months after the diagnosis.

Conclusions

Extranodal natural killer/T-cell lymphoma, nasal type is an aggressive disease and may relate extensive ocular tissue and course dramatic vision deterioration. It is important to observe ocular related and begin aggressive combined therapy as early as possible after diagnosis.

Clinical characteristics and treatment outcomes of diffuse large B-cell lymphoma involving the eye and ocular adnexa in East Asia

PURPOSE

To investigate the clinical features and outcomes of diffuse large B-cell lymphoma (DLBCL) involving the eye and ocular adnexa in an East Asian population and emphasize the importance of prompt biopsy and treatment in unusually progressive ocular adnexal DLBCL for better visual outcomes.

METHODS

Retrospective case series of 38 patients diagnosed with DLBCL involving the eye and ocular adnexa between 1995 and 2018 at a single tertiary institution.

RESULTS

There were 38 patients (22 men, 16 women), 22 (57.9%) of which had ocular adnexal lymphoma (OAL) and 16 (42.1%), vitreoretinal lymphoma (VRL). The OAL group showed higher rates of unilateral involvement (p = 0.01) and localized disease presentation (p = 0.01). Thirteen (59.1%) of 22 OAL patients were primary diseases and 9 (40.9%) were secondary. Between primary and secondary OAL groups, there was no statistical difference in clinical characteristics such as age, gender and laterality (p = 0.47, p = 0.19 and p = 0.66, respectively). All secondary OAL cases were either disseminated or relapsed by definition and only two cases (15%) of primary OAL showed disseminated presentation (p < 0.01). Six (37.3%) of 22 OAL patients showed a rapid decrease in visual acuity within 15 days and the visual recovery was irreversible in 3 of them.

CONCLUSION

OA-DLBCL has a grave prognosis and its visual outcomes largely depend on the timing of diagnosis and treatment. When a high-grade lymphoma is suspected, prompt biopsy and treatment should be performed to ensure optimal visual, clinical and survival outcomes.
