Orbital Metastasis as the First Manifestation of Hepatocellular Carcinoma, and Its Effective Treatment with Combined Dual Immunotherapy: A Case Report and Review of the Literature.

BACKGROUND Orbital metastasis originating from hepatocellular carcinoma (HCC), particularly as an initial manifestation in patients without a known history of HCC, is rare. Few reports exist on the treatment of patients having HCC with orbital metastasis using targeted therapy or immunotherapy. CASE REPORT We report a case of advanced-stage HCC in a 65-year-old man who first presented with progressive, painless blurred vision and proptosis of the right eye for 2 weeks. The patient had no history of chronic liver disease or cancer. Computed tomography revealed an enhancing hyperdense extraconal mass in the right orbit; a biopsy revealed metastatic HCC. Abdominal CT, which was performed to investigate the primary cancer, revealed a 1.2×1.6-cm arterial-enhancing nodule with venous washout in hepatic segment 5, associated with liver cirrhosis. The patient's serum alpha-fetoprotein level was 70.27 ng/dL. Chest computed tomography revealed lung metastasis. Thus, first-line systemic therapy combining durvalumab and tremelimumab was initiated alongside palliative radiotherapy targeting the right orbit, which began 1 week after the first dose of dual immunotherapy. The patient had significant clinical improvement, reduced proptosis, and serum alpha-fetoprotein levels. CONCLUSIONS Although orbital metastasis is a rare manifestation of HCC, physicians should recognize and consider aggressive investigations for early diagnosis, especially in patients with existing risk factors for HCC. Dual immunotherapy with durvalumab and tremelimumab in combination with radiotherapy can be considered a potential treatment option for managing advanced HCC with orbital metastasis.

[Metastasis in the periocular region]. / Metastase in der periokulären Region.

Orbital and periocular metastatic tumors used to be considered very rare; however, with the constant updating of drugs and detection methods for cancer treatment, new chemotherapies and radiation treatments are being used. The life expectancy of cancer patients has become longer and periocular metastases are becoming easier to detect. Our knowledge of this rare disease of metastases also needs to be updated. This article reviews the incidence, symptomatic presentation, clinical features, diagnostic approaches and current treatment of metastatic tumors of the orbit and ocular adnexa in these patients.

[Interdisciplinary Management of Orbital Diseases]. / Interdisziplinäre Therapie der Erkrankungen der Orbita.

Diagnosis and therapy of orbital diseases is an interdisciplinary challenge, in which i.e. otorhinolaryngologists, ophthalmologists, radiologists, radiation therapists, maxillo-facial surgeons, endocrinologists, and pediatricians are involved. This review article describes frequent diseases which both, otolaryngologists and ophthalmologists are concerned with in interdisciplinary settings. In particular the inflammatory diseases of the orbit including orbital complications, autoimmunological diseases of the orbit including Grave´s orbitopathy, and primary and secondary tumors of the orbit are discussed. Beside describing the clinical characteristics and diagnostic steps the article focusses on the interdisciplinary therapy. The review is completed by the presentation of most important surgical approaches to the orbit, their indications and possible complications. The authors tried to highlight the relevant facts despite the shortness of the text.

Successful Treatment of Refractory Orbital Plasmacytoma with Chimeric Antigen Receptor T Cell Therapy: A Case Report and Review of the Literature.

Orbital plasmacytoma is a rare plasma cell tumor that may arise as an aggressive form of extramedullary multiple myeloma. Treatment modalities include surgical excision, radiation, and chemotherapy. Chimeric antigen receptor T cell therapy is currently reserved for refractory disease. The authors present a case of a 69-year-old woman with an extensive orbital plasmacytoma refractory to multimodal therapy who was treated with idecabtagene vicleucel chimeric antigen receptor T cell therapy. Four days after infusion, the patient exhibited grade 1 cytokine release syndrome, which resolved with tocilizumab. The orbital plasmacytoma significantly decreased in size 1 month after treatment and demonstrated complete serological response and sustained tumor burden reduction at 10-month follow-up. This case highlights the efficacy of chimeric antigen receptor T cell therapy for refractory orbital plasmacytoma and calls attention to potential inflammatory toxicities.

Clinical, Diagnostic, and Treatment Characteristics of Orbital Liposarcoma.

PURPOSE: To clarify the clinical, diagnostic, and treatment characteristics of orbital liposarcoma. DESIGN: Retrospective observational case series. METHODS: A review was performed of electronic medical records, histopathology, radiological images, and follow-up information for 21 patients with orbital liposarcoma. RESULTS: The predominant clinical manifestation of this disease was painless exophthalmos. The most frequently encountered pathological types were well-differentiated and myxoid liposarcoma. Preoperative radiological images from 15 patients showed that orbital liposarcoma initially developed in extraocular muscle in 9 patients. Furthermore, all well-differentiated liposarcomas exhibited the radiographic characteristics of irregular and ill-defined adipose tissue, whereas only 12.5% of myxoid liposarcomas had the imaging characteristics. For the patients who exclusively underwent surgery, all of those with subtotal excisions experienced recurrence, 63.6% of marginal excisions recurred, and 50% of wide excisions resulted in recurrence. However, none of the patients who underwent marginal excisions or wide excisions combined with adjuvant radiotherapy exhibited recurrence. The analysis of magnetic resonance imaging findings in 3 patients who underwent neoadjuvant radiotherapy revealed that the tumor size remained stable in a patient with well-differentiated liposarcoma, whereas another patient with the same type of tumor exhibited a gradual increase in size. Conversely, a patient with myxoid liposarcoma experienced a significant reduction in tumor size following neoadjuvant radiotherapy. CONCLUSION: Orbital liposarcoma demonstrated a propensity for developing in the extraocular muscle. The radiological images of orbital well-differentiated liposarcomas were characterized by irregular and ill-defined adipose tissue. Surgery combined with radiotherapy demonstrated potential in reducing recurrence rates. Notably, orbital myxoid liposarcoma exhibited greater sensitivity to radiotherapy compared to well-differentiated liposarcoma.

[Orbital tumors]. / Tumoren der Orbita.

Orbital tumours include a variety of orbital diseases of different origins. In the case of malignant orbital tumours, early detection is important so that treatment can be initiated promptly. Neuroradiological imaging, in particular magnetic resonance imaging (MRI), plays an important role in the diagnostic of orbital tumours. In adults, lymphoproliferative diseases, inflammations and secondary orbital tumours are most frequently found, whereas in children mostly dermoid cysts, optic gliomas and capillary haemangiomas are found. Optic glioma is a pilocytic astrocytoma and accounts for two thirds of all primary optic tumours. Optic nerve sheath meningiomas mostly affect middle-aged women. In childhood, retinoblastoma is the most common intraocular tumour. This is an aggressive malignant tumour which can occur unilaterally or bilaterally. Based on the imaging findings, differential diagnoses can usually be easily narrowed down using criteria such as age of manifestation, frequency, localisation and imaging characteristics.

Comprehensive analysis of orbital lymphoma in a Turkish cohort: clinical characteristics, histological subtypes, treatment modalities, prognostic factors, and implications for management.

The study analysed the clinical characteristics, treatment approaches, and survival outcomes of 97 consecutive patients with orbital lymphoma (OL) over a 25-year period at. The median age of the patients was 57.6 years, and 59.8% (n = 58) were male. Marginal zone lymphoma constitutes the most prevalent subtype, accounting for 67% of cases, whereas other common subtypes include diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, Burkitt lymphoma, and T-cell lymphomas. Unilateral involvement was observed in the majority of cases (72.3%). Common clinical presentations included mass (30.9%), swelling (26.8%), and epiphora (11.3%). Of the patients, 7.2% received rituximab alone, 14.4% received radiotherapy alone, 48.5% received chemotherapy, 27.8% received radiotherapy plus rituximab, 22.7% received radiotherapy plus chemotherapy, and 5.2% underwent surgery as the first-line treatment. During a median follow-up of 4.3 years, 15.5% of patients experienced relapse or disease progression. The 5-year and 10-year progression-free survival rates were 84.1% and 79.1%, respectively. This study contributes to our understanding of OLs and provides a foundation for further investigations in this field. Male gender, presence of B symptoms, advanced stage, secondary orbital lymphoma, aggressive histological subtype, and elevated serum lactate dehydrogenase levels were associated with poorer (either inferior or worse) progression-free survival.

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.

Differences in clinical features and prognosis between orbit adenoid cystic carcinoma and adenocarcinoma: a study from the SEER 18 database.

PURPOSE: To analyze the differences in clinical features, treatment methods, prognosis, and etiological factors between lacrimal gland, adenoid cystic carcinoma (LGACC), and orbit adenocarcinoma. MATERIAL AND METHODS: All cases of LGACC and orbit adenocarcinoma between 1975 and 2016 were obtained from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database. RESULTS: The 3-, 5-, and 10-year overall survival (OS) rates for 118 LGACC cases were 82.2%, 70.2%, and 51.7%, respectively. The 3-, 5-, and 10-year OS rates for 29 orbit adenocarcinoma cases were 76.3%, 51.2%, and 51.2%, respectively. There was no statistically significant difference in the overall survival rate between LGACC and adenocarcinoma (P=0.566). Univariate analysis showed that the proportion of deaths was higher with increased age and year of diagnosis in LGACC (P=0.010 and P=0.000), while the death rate was higher for poorly differentiated adenocarcinoma (P=0.020). The survival rate for LGACC was lower in patients ⩾60 years of age than in those <60 years of age (P=0.035). There was no significant difference in survival rate between adenocarcinoma patients ⩾60 years and <60 years old (P=0.102). There was no significant correlation between the degree of tumor differentiation and the survival rate for LGACC or adenocarcinoma (P=0.401 or P=0.098, respectively). CONCLUSION: There is no significant difference in prognosis between LGACC and adenocarcinoma. The degree of tumor differentiation is not associated with prognosis for either LGACC or adenocarcinoma.

Spindle Cell/Sclerosing Rhabdomyosarcoma of the Orbit.

A 3-year-old boy developed proptosis over 3 weeks. CT and MRI disclosed a 3.2 × 1.9 cm soft-tissue mass of the right extraconal and intraconal orbit with sphenoid bone erosion. After debulking through an upper eyelid crease incision, the tumor was diagnosed as a spindle cell/sclerosing rhabdomyosarcoma. DNA sequencing was negative for an L122R mutation in MyoD1 . Spindle cell/sclerosing rhabdomyosarcoma is an uncommon variant of this neoplasm, and only 2 patients with orbital tumors have been reported in 2 case series. Spindle cell/sclerosing rhabdomyosarcomas confined to the orbit are considered to have an excellent prognosis when treated with chemotherapy and radiation therapy. Diagnosis and treatment planning rely on histology, immunohistochemistry, and molecular analysis.

A survey across orbital lymphoma in Poland: Multicenter retrospective study of polish lymphoma research group (PLRG).

OBJECTIVE: To investigate the prevalence of histopathological subtypes, the clinical stage at presentation and treatment modalities in Polish patients with orbital lymphoma (OL) and to determine prognostic outcomes. METHODS: The retrospective study of 107 patients with OL treated in a 14-year period in Polish hematological centers. The analysis included histopathological subtype, disease clinical advancement, treatment modalities, progression-free survival (PFS), and overall survival (OS). RESULTS: The median patient age was 60 years (range 51-71). Mucosa-associated lymphoid tissue (MALT) lymphoma accounted for slightly more than half of all cases of orbital lymphoma (51%). The second most common subtype was diffuse large B-cell lymphoma (DLBCL) (29%). Primary orbital lymphoma was diagnosed in 48% of all patients. According to the Ann Arbor, localized stage IE of orbital lymphoma was diagnosed only in 39% of all patients. Systemic involvement was observed in more than half of all patients (52%). The median follow-up period was 30 months (range 0-160 months). Patients with non-MALT lymphoma had a significantly inferior PFS compared to patients with MALT lymphoma, (p = 0.047). Patients with primary orbital lymphoma had a superior PFS compared to patients with secondary orbital lymphoma [median PFS 104.5 months vs. 33.4 months], (p = 0.069). Younger patients with MALT lymphoma were characterized by superior PFS (median PFS not reached) compared to other studied subgroups of patients (older patients with MALT lymphoma, younger and older non-MALT lymphoma patients) with a median PFS of 30.5, 32.2, 32.6 months respectively (p = 0.039). Patients treated with chemotherapy alone had inferior PFS compared to patients treated with combined therapies (p = 0.034). The median PFS across patients who received chemotherapy alone was 23.7 months, whereas across other patients was 73.9 months. CONCLUSIONS: Secondary lymphoma accounts for more than half of the orbital lymphoma in Polish population. The advanced clinical stage of the disease (non-IE according to Ann Arbor) concerns two-thirds of the overall population of patients with orbital lymphomas and one-third of MALT lymphoma patients. The high incidence of advanced stages of orbital lymphoma may indicate the need for combined treatment. Combined orbital lymphoma treatment is associated with superior PFS compared to chemotherapy alone in overall population of patients with orbital lymphoma.

Diagnostic challenge: Diffuse large B-cell lymphoma masquerading as orbital cellulitis.

We report a clinical case of orbital lymphoma masquerading as orbital cellulitis. Orbital lymphoma and lymphoma of the orbital adnexa are relatively rare types of lymphoma. They represent the malignant end of a spectrum of lymphoproliferative lesions that occur in the orbit, conjunctiva and eyelid. Diffuse large B-cell lymphomas (DLBCL) with variable clinical presentations have a relatively poor prognosis with rapid visual loss. Therefore, thorough evaluation and assessment with a multi-specialty effort are warranted for earlier diagnosis and initiation of treatment to save life and prevent sight loss.

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.

Orbital metastases of breast carcinoma.

SUMMARY: Orbital metastases, although rare, originate from systemic breast cancer in up to 35% of patients. Metastases more commonly arise from invasive lobular carcinomas than from invasive ductal carcinomas. Due to the diagnostic challenge of determining the primary site for the metastases, immunohistochemistry is essential. Clinical and radiological information are usually insufficient. This disease typically progresses quickly and has a poor prognosis. We report the case of a 55-year-old female who presented in 2017 with a left breast carcinoma and defaulted treatment during many different stages, then returned three years later with a right orbital mass which was confirmed to be a breast cancer metastasis on biopsy.

Sino-orbital metastasis as the initial presentation of advanced breast cancer.

A woman in her 70s presented with reduced vision in her left eye, progressive narrowing of right eye opening for 6 months and anosmia. On examination, she had right enophthalmos and pseudoptosis with inferior globe dystopia. Her visual acuity was 6/9 and nil light perception in the right and left eyes, respectively. Extraocular muscle examination showed limited right up gaze. Funduscopy showed a normal right optic disc and left optic disc atrophy. Systemic examination revealed left breast ulceration with skin tethering. CT revealed an infiltrative mass invading the ethmoidal sinuses, frontal sinuses and both orbits. A histological diagnosis of infiltrative ductal breast carcinoma was made after nasal endoscopic and left breast biopsy. She underwent palliative chemoradiotherapy and survived with good disease control after 1 year. Metastatic carcinoma is a differential diagnosis of a sino-orbital mass, and comprehensive clinical assessment is indicated for all patients presenting with non-acute eye injury.

Orbital Metastasis From Gastric Cancer Presenting as Orbital Cellulitis With Ptosis.

ABSTRACT: We report a rare case of orbital metastasis that originated from gastric carcinoma, which presented as orbital cellulitis with ptosis. Orbital metastasis accounts for about only 1% to 13% of orbital tumors. Orbital metastasis in orbital soft tissue or bony structures is very uncommon.A female patient with advanced gastric cancer with multiple metastases was referred to our clinic. She showed mild swelling and ptosis in her left eye. Contrast enhanced computed tomography imaging suggested orbital metastasis from gastric cancer in the superolateral aspect of the orbit. Based on her general condition and after consulting with an oncologist, we determined that fine needle biopsy and excisional biopsy for pathological diagnosis should not be performed as a therapeutic treatment.It is important to distinguish orbital metastasis from orbital cellulitis with ptosis especially for patients with family or personal history of cancer. Clinicians should collect a through medical history from patients and suggest contrast enhanced computed tomography for appropriate diagnosis. Assessing quality of life and aggressive treatment options is crucial for determining the best treatment for orbital metastasis.

Granular Cell Tumor of the Orbit: Review of the Literature and a Proposed Treatment Modality.

PURPOSE: To document a unique case of granular cell tumor of the orbit, located lateral to and abutting the optic nerve, that benefited from treatment with proton beam irradiation, with a comprehensive review of the literature on granular cell tumor of the orbit. METHODS: Clinicopathologic case report with detailed imaging features and histopathologic and immunohistochemical evaluation for cytoplasmic tumor biomarkers differentiating granular cell tumor (GCT) from it mimicking lesions with relevant literature citations. The authors reviewed 20 cases of orbital GCT from 2011 to 2020 in addition to 40 cases from 1948 to 2011 and included a summary of imaging and clinical features, outcomes, and recommended treatment modalities. RESULTS: A 32-year-old man with 1-year history of left retrobulbar pain and diplopia on lateral gaze, intermittent left eyelid swelling, and a tonic left pupil was found to have a fusiform intraconal mass extending toward the orbital apex and abutting the optic nerve. Histopathologic and immunohistochemical investigations collectively supplied data diagnostic of a GCT with an initial low proliferation rate. GCT is a soft tissue neoplasm that originates in the nervous system and can occur anywhere in the body. This enhancing tumor is isointense to gray matter on T1-weighted MRI, hypointense on T2. After an incisional biopsy, the patient's symptoms persisted, and follow-up imaging several months later revealed further growth of the mass. The impossibility of complete surgical removal prompted the decision to treat with proton beam radiation therapy, which resulted in substantial regression in the size of the residual tumor. Most frequently involving the inferior rectus muscle (42%), orbital GCT is usually benign with only 4 reported cases of malignant orbital GCT (7%). Wide surgical resection with complete removal is usually curative for benign orbital GCT, and proton beam radiation therapy can aid in tumor shrinkage. CONCLUSIONS: GCT should be considered in the differential diagnosis when encountering patients with mass lesions involving the extraocular muscles, peripheral nerves, or less frequently, the optic nerve or orbital apex. Immunohistochemical analysis of biopsied tissue is required for the definitive diagnosis of GCT. Consideration of adjuvant therapies such as proton beam radiation therapy may be appropriate in cases of incomplete surgical resection of benign GCT. Proton beam radiation therapy can be an excellent therapeutic option for symptomatic relief and residual tumor size reduction with an acceptable toxicity profile.

Acute inflammatory presentation of orbital metastasis from urothelial carcinoma: a case report.

Orbital metastasis of urothelial carcinoma is very rare; only 22 cases have been documented. In this case report, we describe a patient 1 month status post transurethral resection of urothelial carcinoma who presented with a clinical picture suggestive of orbital cellulitis. However, neither broad-spectrum antibiotics nor a subsequent trial of methylprednisolone was effective at relieving the patient's symptoms. CT imaging of the head, chest, abdomen, pelvis, and lower extremity showed no signs of metastatic disease. Six days after presentation, punch biopsy of the mass was performed and confirmed urothelial carcinoma metastatic to the orbit. The patient died 3 months later due to multiple sites of distant metastasis. This case report suggests that a high index of suspicion for orbital metastasis is important for patients with a history of urothelial carcinoma with new and acute onset of ocular symptoms and emphasizes the need for urgent systemic evaluation and treatment.
