[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.

Metastasis of small cell lung cancer to bilateral extraocular muscles: a case report.

BACKGROUND: Orbital metastasis is a possible complication of small cell lung cancer and a pattern of bilateral invasion of the extraocular muscles has rarely been reported in literature. CASE PRESENTATION: A 46-year-old white male with a past medical history of smoking and stage IV small cell lung carcinoma presented with loss of vision and pain in the left eye. Examination revealed bilateral proptosis and left afferent pupillary defect, and visual acuity was hand motion on the left eye and 4/10 on the right eye. An orbital computed tomography scan showed a compression of the left optic nerve between the extraocular muscles at the apex, and a lateral canthotomy was performed for a new-onset compressive optic neuropathy, with residual visual improvement. There was also significant enlargement of the extraocular muscles in the right orbit. The patient was maintained in palliative treatment with both chemotherapy and local medical and surgical (amniotic membrane cover for exposure keratopathy) ophthalmological treatments until he eventually died 5 months after. CONCLUSION: Bilateral metastasis to the extraocular muscles is a very rare manifestation of small cell lung cancer and the palliative treatment in these cases is challenging.

A Case Series of Choroidal and Orbital Neuroendocrine Tumors: Metastasis: Two Patients Treated With Peptide Radionuclide Therapy.

ABSTRACT: Neuroendocrine tumors (NETs) are rare cancers with heterogeneous histologies, response to treatments, and prognoses. Majority of these cancers originate in the gastrointestinal tract and metastasize to the liver. We report the cases of 5 patients with low-grade NET disease with rare metastases to the choroids. Two of the patients were treated with peptide receptor radionuclide therapy (lutetium 177 [ 177 Lu]). This is the first report confirming peptide radionuclide therapy safety in patients with low-grade NET with ocular metastases.

Uncommon Hematogenous Metastasis: Orbital Involvement in Uterine Cervical Cancer.

BACKGROUND Although screening for uterine cervical cancer (UCC) and vaccination programs for human papilloma virus (HPV) have been implemented in many countries, women >65 years may not have access to or comply with cervical cancer screening. Women >65 years may present with advanced-stage cervical carcinoma with a poor outcome. Metastatic UCC is often diagnosed, and there are 2 types of metastases related to different treatments and survival rate: hematogenous metastasis and lymphatic metastasis. Hematogenous metastasis is relatively unusual, and it most commonly involves lung and bone locations. Orbital metastasis is an extremely rare hematogenous metastasis in patients with UCC. CASE REPORT A 70-year-old woman receiving dialysis presented to a local hospital due to general fatigue for 5 months. She was diagnosed with locally advanced UCC and underwent radiation therapy (RT). Twenty days after RT, skin masses appeared, and 34 days after RT, right exophthalmos induced by an orbital mass appeared. We diagnosed skin and orbital masses as metastases from UCC, and performed RT to the orbital tumor. The tumor shrank and the visual symptoms disappeared. Regrettably, the patient died of cancer 7 months after the orbital RT; however, no eye symptoms recurred until her death. CONCLUSIONS This report describes a rare presentation of UCC with metastasis to the orbit, and highlights that cervical cancer may still present at an advanced stage, particularly in older women. In this case, RT to the orbital metastasis from UCC was effective and contributed to the patient's quality of life.

Rare periorbital, pseudocystic metastasis of squamous cell carcinoma of the bladder: Case report and review of the literature.

We present the case of a man in his fifties with a history of bladder carcinoma who presented with a large periorbital cystic lesion that was found to be a metastasis. Bladder carcinomas are a very rare cause of peri-/orbital metastasis. The primary tumor in this case predominately showed squamous cell differentiation and small areas of adenoid differentiation. To our knowledge only one previous case of orbital metastasis from squamous cell carcinoma of the bladder has been reported. Cyst formation in bladder cancer metastasis has not been reported and is very rare for orbital metastases in general. The pathogenesis of metastatic cyst development is not fully understood and may vary from case to case. A biopsy of an atypical cyst is indicated.

Metastatic neuroendocrine tumor masquerading as orbital cysticercosis.

Orbital metastases secondary to neuroendocrine tumors are exceedingly rare. We present a unique case of a 30-year-old female initially presenting with fever, chills, periorbital swelling, and painful proptosis. CT orbits revealed two ovoid-shaped ring-enhancing lesions in the right lateral and superior rectus muscles and clear sinuses, atypical for infectious post-septal cellulitis. Further work-up included serologic analysis, auto-immune panel, and MRI. Further imaging showed pseudocystic orbital lesions mimicking orbital cysticercosis. Additionally, given the bilateral nature of the lesions and patient's country of origin, this parasitic process was highly suspected. A course of albendazole and steroids led to resolution of symptoms. With a presentation at age 30, this is by far the youngest case reported in literature to date.

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.

A Case of Endonasal Endoscopic Surgery for Intraorbital Metastasis of Gastric Ring Cell Carcinoma.

Gastric signet ring cell carcinoma has well-known metastatic features, including peritoneal dissemination and carcinomatous lymphangitis of the lung, but no intraorbital metastases were reported previously. A woman in her 60s developed left eye pain, sudden vision loss, and headache 12 years after gastric cancer treatment. Symptoms did not improve despite steroid pulses. Craniotomy showed no malignant findings. The patient was referred to our department for symptomatic relief and biopsy due to the lack of a definitive diagnosis and no improvement in her ocular pain. Endonasal endoscopic surgery was performed for diagnostic purposes and to relieve symptoms through orbital decompression. Preoperative computed tomography examination revealed a tumor at the left medial orbit, extending to the orbital apex. Orbital decompression through the open left medial orbital wall was performed with biopsy of the intraorbital tumor. Pathological findings were consistent with metastatic signet ring cell carcinoma. Pain and subjective improvement of visual acuity were noted the day after surgery. Twelve months postoperatively, diplopia remains, but there has been no worsening of symptoms.

Pleomorphic Invasive Lobular Cancer of the Breast Presenting with Orbital Metastasis: A Case Report.

BACKGROUND: Orbital metastasis of breast cancer is an unusual condition, especially in the absence of a previous diagnosis of primary breast cancer. The main MRI findings in patients with orbital metastasis are retroorbital soft tissue with thickening of extraocular muscles. Paradoxical enophthalmos secondary to fibrosis can be seen. CASE REPORT: In this case report, we present a 75-year-old female patient with left eye pain and blurred vision and retraction. Although there was no evidence of malignancy in the biopsy of the orbita; since the patient's complaints continued despite idiopathic pseudotumor treatment, mammography was recommended to rule out the possibility of breast cancer metastasis. Her mammography revealed a suspicious lesion in the left breast and proved to be pleomorphic invasive lobular cancer. CONCLUSION: Breast cancer metastasis should be kept in mind in women with pseudotumor -like the involvement of the orbita.

Orbital metastasis from neuroendocrine tumour: Case report and literature review.

Orbital metastases from neuroendocrine tumour are rare entities. An incidental finding of orbital metastasis originating from neuroendocrine tumour is presented in the context of a comprehensive review of all case reports and series published to date. Demographics, clinical features, diagnostic work-up, treatment and prognostic data from the published literature are discussed. Ninety-five patients with orbital metastases from neuroendocrine tumours have been reported so far. Average age at presentation is 63.8 years (range 25-86), with no significant gender predominance. Gastrointestinal tract is the most common site of primary neuroendocrine tumours (62-85%). Typical presentation includes proptosis (80-85%) and diplopia (27-62%) in patients with known primary neuroendocrine tumour elsewhere. Histological subtype and presence of metastases seem to be important prognostic factors. Incidental finding of neuroendocrine tumour mestastases in asymptomatic patients with unknown primary disease is uncommon. In such cases, orbital biopsy and structural and functional imaging are essential to establish a diagnosis and stage the disease.

Rare Orbital Metastasis Originating from Ampullary Adenocarcinoma.

BACKGROUND: Orbital metastasis from ampullary carcinoma is rare, with no previously reported cases. CASE PRESENTATION: We report the case of a 60-year-old man who complained of a right-sided headache, blurred vision, progressive proptosis, ptosis, and right eye pain for 3 months. His past medical history included an ampullary adenocarcinoma stage IIIA treated via the Whipple procedure and adjuvant chemoradiotherapy 1 year ago. However, he was lost to follow-up. Computed tomography of the orbit showed a soft tissue lesion in the right orbital fossa measuring 3.3 × 2 × 2 cm. An orbital mass biopsy demonstrated an intestinal-type adenocarcinoma that tested positive for cytokeratins 7 and 20 and CDX2 on immunohistochemical staining. The pathologic diagnosis was metastatic adenocarcinoma from the ampulla of Vater. Despite oncological treatment, the patient's illness progressed. He received palliative treatment and died 1 month later. CONCLUSIONS: We presented a rare case of orbital metastasis from ampullary adenocarcinoma. This should be considered in the differential diagnosis of patients with a history of ampullary adenocarcinoma who present with symptoms referring to the relevant locations.

Chromosome 10 abnormality predicts prognosis of neuroblastoma patients with bone marrow metastasis.

BACKGROUND: Neuroblastoma (NB) is the most common extracranial solid tumor in children. It is known for high heterogeneity and concealed onset. In recent years, the mechanism of its occurrence and development has been gradually revealed. The purpose of this study is to summarize the clinical characteristics of children with NB and abnormal chromosome 10, and to investigate the relationship between the number and structure of chromosome 10 abnormalities and NB prognosis. METHODS: Chromosome G-banding was used at the time of diagnosis to evaluate the genetics of chromosomes in patients with NB and track their clinical characteristics and prognosis. All participants were diagnosed with NB in the Medical Oncology Department of the Beijing Children's Hospital from May 2015 to December 2018 and were followed up with for at least 1 year. RESULTS: Of all 150 patients with bone marrow metastases, 42 were clearly diagnosed with chromosomal abnormalities. Thirteen patients showed abnormalities in chromosome 10, and chromosome 10 was the most commonly missing chromosome. These 13 patients had higher LDH and lower OS and EFS than children with chromosomal abnormalities who did not have an abnormality in chromosome 10. Eight patients had both MYCN amplification and 1p36 deletion. Two patients had optic nerve damage and no vision, and one patient had left supraorbital metastases 5 months after treatment. CONCLUSIONS: The results indicated that chromosome 10 might be a new prognostic marker for NB. MYCN amplification and 1p36 deletion may be related to chromosome 10 abnormalities in NB. Additionally, NB patients with abnormal chromosome 10 were prone to orbital metastases.

Metastatic Orbital Tumor From Breast Ductal Carcinoma With Neuroendocrine Differentiation Initially Presenting as Ocular Symptoms: A Case Report and Literature Review.

Background: Orbital metastases from cancers of various organs can arise via the hematogenous route, and many originate from breast, prostate, and lung cancers. Such metastatic orbital tumors may be diagnosed before the primary tumor. We have encountered a case of breast ductal carcinoma with neuroendocrine differentiation that metastasized to the orbit and responded to chemotherapy, with improvement in visual function. Case Presentation: A woman in her fifties visited our ophthalmology department with a chief complaint of foreign body sensation and exophthalmos in her right eye. An elastic soft mass was palpated from the lateral orbit to the temporal region. A systemic examination revealed breast cancer and a metastatic orbital tumor. Excisional biopsy of the breast revealed a diagnosis of invasive ductal carcinoma with neuroendocrine differentiation, and immunohistochemical examination was negative for cytokeratin 7, making the case unusual. Chemotherapy was remarkably effective, and the tumor size decreased, resulting in improvement of visual function. Her general condition and quality of life are still good at present. We searched the PubMed English language literature focusing on metastatic orbital tumors from breast cancer in which ocular symptoms had been the initial presenting sign. No previous reports have documented neuroendocrine differentiation or cytokeratin 7 expression in isolated orbital metastases from breast cancer. Although it is not possible to be certain from this case alone, we speculated that some such cases might involve cytokeratin 7-negative invasive breast cancer with neuroendocrine differentiation. Conclusion: We have described our experience of a very rare case of cytokeratin 7 negative breast ductal carcinoma with neuroendocrine differentiation that metastasized to the orbit and formed a solitary giant tumor initially manifesting as ocular symptoms.

Isolated Unilateral Orbital Metastasis From Ewing Sarcoma Detected on FDG PET/CT Scan.

ABSTRACT: Ewing sarcoma is the second most common primary malignant bone tumor that usually affects diaphysis of long bones during the second decade of life. Isolated unilateral orbital metastasis from this tumor presenting as proptosis is extremely rare. Here we report a case of 11-year-old boy where whole-body FDG PET/CT scan detected primary an Ewing sarcoma site in the left femur and isolated orbital metastasis in the left eye. Follow-up PET/CT scan after 6 cycles of chemotherapy showed resolution of the previously seen lesions.
