Ocular adnexal diffuse large B-cell lymphoma: local disease correlates with better outcomes

Primary Cutaneous Follicle Center Lymphoma of the Eyelid in a Young Man

A 20-year-old male presented with a fast-growing nodule in his right inferior eyelid, no relevant history was obtained. Final histopathologic diagnosis of primary cutaneous follicle center lymphoma (CD20+, CD10+, bcl6+, bcl10+, mum1+, PAX5+, and bcl2-) was determined. The patient had a complete negative systemic work-up, and 3 cycles of consisting of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy were completed. The initial histopathologic diagnosis had been a non-Hodgkin diffuse large B-cell lymphoma which is an infrequent lymphoma type for this location too. To our knowledge, this is the youngest person reported presenting with an eyelid primary cutaneous follicle center lymphoma.

Orbital mass as the presenting symptom of diffuse large B-cell lymphoma causing spontaneous tumor lysis syndrome and rapid multisystem organ failure

A 68-year-old male presented with a one-month history of progressive proptosis and vision loss in the left eye. Examination of the left eye showed visual acuity of NLP, marked relative proptosis of 10 mm, and complete external ophthalmoplegia. CT orbits showed an extensive left orbital lesion with proptosis. Urgent orbital biopsy was undertaken. Intraoperatively, the patient developed new atrial flutter and fever. Bloodwork revealed metabolic derangements suggestive of tumor lysis syndrome. Systemic evaluation revealed a large tumor burden involving the retroperitoneal space. Histopathology of the orbital specimen showed non-germinal center diffuse large B-cell lymphoma. The patient passed away 3 days postoperatively due to rapidly progressive multisystem organ failure. Our case demonstrates an unusually aggressive presentation of DLBCL in which orbital mass was the first presentation of spontaneous tumor lysis syndrome owing to large systemic tumor burden.

Diffuse large cell lymphoma of the lacrimal sac may mimic as acute dacryocystitis

A 36-year-old male patient presented with a firm swelling in the left lacrimal sac region with a history of recurrent episodes of acute dacryocystitis, which partly resolved with systemic antibiotics. Computed tomography showed diffuse soft tissue mass without bony erosion in the same area. Incisional biopsy confirmed diffuse large cell lymphoma of non-Hodgkin's type by histopathology and immunohistochemistry. Oncologists did not detect systemic involvement, and the patient received six cycles of cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisolone (CHOP). Epiphora was resolved, and no recurrence of the lesion was seen with subsequent dacryocystorhinostomy with intubation and was in good health for up to 3 years of follow-up. Although primary lacrimal sac lymphoma is a rare entity, high suspicion, and prompt action in atypical cases can save lives from aggressive diffuse large cell lymphoma.

Primary diffuse large B-cell lymphoma of orbit: A population-based analysis

Objective

Primary orbital lymphoma (POL) accounts for an essential part of adult orbital malignancies. Nevertheless, it remains a relatively rare lymphoid malignancy, accounting for <1% of all non-Hodgkin's lymphoma (NHL) cases. Orbital diffuse large B-cell lymphoma (DLBCL) is one of the most prevalent subtypes of POL that confers the worst outcomes. The prognostic determinants of orbital DLBCL remain unknown. Therefore, a retrospective analysis was conducted by investigating the Surveillance, Epidemiology, and End Results (SEER) database for independent predictive factors for the prognosis of orbital DLBCL.

Materials and methods

Using the SEER program, we acquired patient data including demographics, clinical characteristics, and treatment strategies. Our cohort included cases of primary orbital DLBCL diagnosed from 2000 to 2017. We conducted Kaplan-Meier analyses to visualize the overall survival (OS) and cause-specific survival (CSS). The Cox proportional hazard regression models were applied to assess the effects of these prognostic factors on OS and CSS.

Results

The present cohort included 332 patients with orbital DLBCL. Age was the most impacted variable by orbital DLBCL. Three independent prognostic variables of orbital DLBCL were identified on diagnosis: advanced age, no radiation treatment, and late-stage (Stage IV). Moreover, patients who underwent chemotherapy demonstrated a greater OS when compared with those who did not. In orbital DLBCL, being unmarried was also a poor prognostic factor.

Conclusion

The current study is the largest population-based case series of orbital DLBCL. The age at the time of diagnosis, marital status, absence of chemotherapy or radiotherapy, and tumor stage were all found to be correlated with worse prognosis.

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.

Diffuse Large B-Cell Lymphoma Arising in the Lacrimal Sac

ABSTRACT

The authors report a single case of diffuse large B-cell lymphoma arising in the lacrimal sac. Diffuse large B-cell lymphoma is a third most common primary ocular adnexal lymphoma, which is the most common primary ocular malignant disease in adults. A patient came to our clinic with epiphora and a growing mass in the lacrimal sac. Enhanced computed tomography imaging suggested the presence of a malignant tumor and surgical excision and biopsy were performed. A final diagnosis of diffuse large B-cell lymphoma was reached by immunohistological and immunochemical staining. Two months after surgery, diffuse large B-cell lymphoma relapse occurred in the lacrimal sac and the patient underwent 6 cycles of chemotherapy. Diffuse large B-cell lymphoma is a curable disease when diagnosed early, and aggressive biopsy during surgery of the lacrimal sac is necessary to diagnose diffuse large B-cell lymphoma in the early stage. It is important to distinguish diffuse large B-cell lymphoma from other lacrimal system diseases.

A Case Report of a Primary Conjunctival Diffuse Large B-Cell Lymphoma: Keeping an Eye out Following a Nasopharyngeal Carcinoma

Primary diffuse large B cell lymphoma of the conjunctiva is a rare disease. In this article, we report the case of a 40-year-old man who had previously been treated with chemotherapy and radiotherapy for undifferentiated carcinoma of nasopharyngeal type (UCNT) and who subsequently developed conjunctival lymphoma. We underline through this observation the importance of thinking about a secondary cancer post-radio-chemotherapy even when the clinical presentation is atypical.

Tissue Necrosis in Epstein-Barr Virus-Negative Orbital Diffuse Large B-Cell Lymphoma

An 82-year-old man presented with a history of diplopia for 5 months and painful swelling of the left eyelids for 3 months. Imaging studies revealed a lesion involving the left extraocular muscles, orbital fat, and optic nerve. Laboratory investigations were negative for Epstein-Barr virus antiviral capsid antigens-immunoglobulin M. Initial biopsy of the lesion was performed and histopathologic examination revealed only necrosis with positivity of cluster of differentiation 20. This prompted a second biopsy of the involved left extraocular muscles and the orbital fat. The results of histopathological and immunohistochemical tests corresponded to Epstein-Barr virus-negative diffuse large B-cell lymphoma, germinal center B-cell type.

A Rare Case of Aggressive, Huge Primary Orbital Lymphoma with Intracranial Extension and Bone Invasion

Primary orbital lymphoma is a rare entity with only 1% of extranodal lymphomas. They usually present to ophthalmologist and surgical reserved for biopsy or tissue diagnosis. We present a patient who was referred to neurosurgery for a rapid growing orbital lymphoma. It grows from a small nodule in the eyelid to a huge, aggressive, disfiguring lesion invading bone and dura with intracranial extension within 3 months. The patient was treated with total surgical excision followed by systemic chemotherapy.

Primary Diffuse Large B-Cell Lymphoma Localized to the Lacrimal Sac: A Case Presentation and Review of the Literature

We report a rare case of diffuse large B-cell lymphoma (DLBCL) of the lacrimal sac in a 50-year-old male. The incidence of primary ocular lymphoma is low and it is considered a rare disease. Moreover, reports of ocular DLBCL are uncommon and the disease remains poorly characterized. Our patient presented for management of osteomyelitis and was incidentally found to have a painless swelling and cyst around his right eye. A PET/CT scan revealed hypermetabolic activity within the lacrimal sac and a subsequent excisional biopsy of the mass yielded histopathology consistent with DLBCL. Consequently, the patient underwent treatment with R-CHOP therapy. The patient responded well to chemotherapy with a substantial shrinkage in tumor burden and the disease remained localized. Herein, we present a rare case of primary ocular lymphoma, highlight the importance of early diagnosis, and review current treatment modalities.

Uniformly Sclerotic Diffuse Large B-Cell Lymphoma of the Orbit

Over a year, a 51-year-old man developed a mass in the anteromedial orbit in the region of the lacrimal sac that caused epiphora. Imaging studies disclosed no bone destruction. On biopsy, a sclerotic lesion was discovered populated by hyperchromatic cells that had been apparently distorted by crush artifact, indicative of fragile cells. The lesion simulated a sclerosing inflammatory process or a desmoplastic metastatic carcinoma. CD20 revealed that the background cells were large neoplastic B-lymphocytes. A systemic workup uncovered widespread skeletal disease. The patient is undergoing R-CHOP chemotherapy with a relatively favorable prognosis due to negative testing for MYC.

Diffuse large B-cell lymphoma and mantle cell lymphoma of the ocular adnexal region, and lymphoma of the lacrimal gland: an investigation of clinical and histopathological features

Diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL) constitute two distinct subtypes of non-Hodgkin lymphoma (NHL) associated with considerable morbidity and mortality. Marked diversities with regard to molecular biology and clinical features are recognized in different subsets of the two lymphomas. Because these differences could be related to the location of the lymphoma, it is of interest to investigate the clinical and histopathological features of DLBCL and MCL involving the ocular adnexal region (i.e. the orbit, eyelids, conjunctiva, lacrimal gland and lacrimal sac). Similarly, the lacrimal gland is the only glandular structure within the orbit. Because the lacrimal gland represents an important part of the immunological system, it is of interest to investigate lymphomas involving this location with regard to clinical and histological characteristics.

PURPOSE

  To characterize the clinical and histopathological features of Danish patients with DLBCL of the ocular adnexal region between 1980 and 2009 and of Danish ocular adnexal MCL patients from 1980 to 2005. Furthermore, the aim of this PhD was to review all specimens from patients with lymphoma of the lacrimal gland in Denmark between 1975 and 2009 to determine the distribution of lymphoma subtypes of the lacrimal gland and to describe the clinicopathological features of these patients.

RESULTS

  A total of 34 patients with DLBCL and 21 with MCL of the ocular adnexal region were identified. Twenty-seven patients had lacrimal gland lymphoma, including four DLBCLs and three MCLs from studies I and II. Elderly patients predominated in all three groups, with median ages of 78, 75 and 69 years in the DLBCL, the MCL and the lacrimal gland lymphoma groups, respectively. MCL patients had a preponderance of males, whereas females prevailed among lacrimal gland lymphoma patients. The orbit was the most common site of involvement in DLBCL and MCL. Most DLBCL patients had unilateral involvement, while MCL patients had a high frequency of bilateral involvement. Similarly, localized lymphoma was relatively frequently seen in DLBCL patients in contrast to the predominance of disseminated lymphoma in the MCL group. The majority of lacrimal gland lymphomas were low grade, and the distribution of subtypes was as follows: extranodal marginal zone lymphoma, 10 (37%); follicular lymphoma, 5 (19%); DLBCL, 4 (15%); MCL, 3 (11%); chronic lymphocytic leukaemia/small lymphatic lymphoma, 2 (7%); and unclassified B-cell lymphoma, 3 (11%). The overall survival rates at 3 and 5 years for the entire study group of DLBCL were 42% and 20%, whereas 58% and 22% of MCL patients were alive 3 and 5 years after the time of diagnosis. The 5-year overall survival rate of lacrimal gland lymphoma patients was 70%. Concordant bone marrow involvement and the International Prognostic Index score were predictive factors for the overall survival in the DLBCL group in Cox regression analysis. Rituximab-containing chemotherapy was associated with an improved survival rate in MCL patients.

CONCLUSIONS

  Diffuse large B-cell lymphoma and MCL involving the ocular adnexal region and lymphoma of the lacrimal gland are prevalent among elderly patients. The overall prognosis in DLBCL and MCL was poor, whereas the prognosis for lacrimal gland lymphoma patients was relatively good. Concordant bone marrow involvement and the International Prognostic Index score were independent predictive factors for mortality in the DLBCL group. Chemotherapy containing rituximab significantly improved survival in the MCL group.

A reappraisal of the diagnostic and therapeutic management of uncommon histologies of primary ocular adnexal lymphoma

Lymphoma is the most common malignancy arising in the ocular adnexa, which includes conjunctiva, lachrymal gland, lachrymal sac, eyelids, orbit soft tissue, and extraocular muscles. Ocular adnexal lymphoma (OAL) accounts for 1%-2% of non-Hodgkin lymphoma and 5%-15% of extranodal lymphoma. Histology, stage, and primary localizations are the most important variables influencing the natural history and therapeutic outcome of these malignancies. Among the various lymphoma variants that could arise in the ocular adnexa, marginal zone B-cell lymphoma (OA-MZL) is the most common one. Other types of lymphoma arise much more rarely in these anatomical sites; follicular lymphoma is the second most frequent histology, followed by diffuse large B-cell lymphoma and mantle cell lymphoma. Additional lymphoma entities, like T-cell/natural killer cell lymphomas and Burkitt lymphoma, only occasionally involve orbital structures. Because they are so rare, related literature mostly consists of anecdotal cases included within series focused on OA-MZL and sporadic case reports. This bias hampers a global approach to clinical and molecular properties of these types of lymphoma, with a low level of evidence supporting therapeutic options. This review covers the prevalence, clinical presentation, behavior, and histological and molecular features of uncommon forms of primary OAL and provides practical recommendations for therapeutic management.

Diffuse large B-cell lymphoma of the ocular adnexal region: a nation-based study

PURPOSE

To characterize the clinicopathological features of diffuse large B-cell lymphoma (DLBCL) of the ocular adnexal region.

METHODS

The present series of orbital and adnexal DLBCLs were found by searching the Danish Registry of Pathology between 1980 and 2009. Histological specimens were re-evaluated using a panel of monoclonal antibodies. Clinical files from all patients with confirmed DLBCL were collected.

RESULTS

A total of 34 patients with DLBCL of the ocular adnexal region were identified. Eighteen of the patients were men. The patients had a median age of 78 years (range 35-97 years). Ninety-seven per cent of the patients had unilateral ocular adnexal region involvement, and the orbit (76%) was the most frequently affected site. Nineteen patients (56%) presented with Stage I lymphoma. Of these, 18 were diagnosed with primary lymphoma. Four patients (12%) had Stage II, one patient (3%) had Stage III and ten patients (29%) presented with Stage IV lymphoma. The 5-year overall survival (OS) rate for the whole study group was 20%. The patients with Stage I lymphoma had a significantly better 5-year OS rate (28%) than patients in Stage II-IV (5-year OS rate, 9%). In Cox regression analysis, concordant bone marrow involvement and the International Prognostic Index (IPI) score were prognostic factors for OS.

CONCLUSIONS

Diffuse large B-cell lymphoma of the ocular adnexal region is mainly prevalent in elderly patients. Most patients had unilateral orbital involvement. The overall prognosis is poor. Concordant bone marrow involvement and the IPI score were independent prognostic factors for mortality.

Diffuse large B-cell lymphoma of the orbit: clinicopathologic, immunohistochemical, and prognostic features of 20 cases

PURPOSE

To evaluate a series of orbital diffuse large B-cell lymphomas (DLBCL) for prognostic features and therapeutic outcomes.

DESIGN

Retrospective multicenter case study of clinical and immunohistochemical features of 20 patients.

METHODS

Clinical, histopathologic, and immunohistochemical features were correlated with outcomes. Immunohistochemistry for biomarkers including Bcl-6, CD5, CD10, CD20, FOXP1, GCET1, and MUM1 was performed to differentiate between 2 major genetic subtypes of DLBCL: activated B-cell-like (ABC) and germinal center B-cell-like (GCB).

RESULTS

Sixteen patients presented with unilateral and 4 with bilateral tumors. Three had bony erosion of the orbit on imaging studies. Of 14 patients with detailed follow-ups, 3 had a prior or concurrent lymphomatous disease; 8 had stage I disease (limited to the orbit) at presentation; and 3 were newly diagnosed with systemic (stage IV) DLBCL. Localized disease was treated with combined systemic chemotherapy, including rituximab and radiation with no deaths to date; there was 1 death related to systemic DLBCL. Clinical staging was the best predictive method and no immunohistochemical feature or subcategory (ABC vs GCB) correlated with outcome.

CONCLUSIONS

Primary orbital DLBCL has a more favorable prognosis than systemic DLBCL and may arise from a preexistent hematolymphomatous neoplasm (4 out of 20 cases). In our series, orbital DLBCL had a 57% likelihood of being restricted to the ocular adnexa. Clinical staging was more helpful in predicting outcome than any single immunohistopathologic feature or combination of biomarkers. Orbital radiation of 30 gray in conjunction with systemic chemotherapy with rituximab can achieve disease-specific survival approaching 100% in purely localized cases.

Diffuse large B-cell lymphoma of the orbit: A tertiary eye care center experience in Saudi Arabia

Primary Diffuse Large B-cell Lymphoma (DLBCL) represents the 2nd most common lymphoma occurring in the orbit, after Mucosal Associated Lymphoid Tissue (MALT) lymphoma. A total of 5 cases of ocular adnexal DLBCL were diagnosed over 25 years of experience at our tertiary eye care center. Two cases involved the lacrimal sac and one case involved the lacrimal gland. In this paper we are presenting the remaining 2 non-lacrimal cases of DLBCL. The first case is a 32 year old male who was referred with a slowly growing, painless mass involving the left medial canthal area as a case of dacryocystitis. The mass was found to be extending into the orbit inferiorly with upward displacement of the left globe. The second case is a 65 year-old lady who presented with unilateral proptosis as a result of a right orbital mass extending to the orbital apex. Histopathologic examination and immunohistochemical analysis of the incisional biopsy in both cases confirmed the diagnosis of Diffuse Large B-cell Lymphoma (DLBCL).

Systemic non-Hodgkin's lymphoma involving the orbit and leptomeninges

We report a case of diffuse large B-cell lymphoma in a 46-year-old female presenting in an unusual manner with stage IVB disease including concurrent orbital and leptomeningeal involvement. The cytologic features and cytogenetics of the malignancy are noted, and the management and progression of the disease, with attention to orbital involvement, is recorded for a period of over 2.5 years, until the patient's death.
