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.

Discrepancy in the Ki67 labeling index of brain and orbital metastatic lesions from gastrointestinal neuroendocrine tumors: A case report / Discrepancia en el índice de etiquetado Ki67 de las lesiones metastásicas cerebrales y orbitales de los tumores neuroendocrinos gastrointestinales: Un informe de caso

Proliferative activity examined by Ki67 labeling index (LI) plays pivotal role for managing gastrointestinal neuroendocrine tumor (GI-NET). Few reports indicated the intra-patient heterogeneity of Ki67-LI among metastatic tumor sites. We report a case of brain and orbital metastases from GI-NET that showed discrepancy of the Ki67-LI. A 71 year-old woman who was diagnosed as GI-NET with liver and bone metastases and performed medical therapy, had headache, right exophthalmos, and pain of right eye and was referred to our department. Magnetic resonance image revealed that tumors in the left occipital region and right orbit. We diagnosed as metastatic brain and orbital tumors from GI-NET. Surgical removal of both symptomatic lesions was performed and the diagnosis was pathologically confirmed. Immunohistochemical studies revealed the discrepancy of the Ki67-LI of the lesions (brain tumor: 8% versus orbital tumor: 22%). Sampling of multiple metastatic sites may prevent underestimate tumor proliferative activity (AU)

La actividad proliferativa examinada por el índice de etiquetado Ki67 (LI) desempeña un papel fundamental en el tratamiento del tumor neuroendocrino gastrointestinal (GI-NET). Pocos informes indican la heterogeneidad intrapaciente del Ki67-LI entre las localizaciones de los tumores metastásicos. Presentamos un caso de metástasis cerebrales y orbitales de GI-NET que mostró discrepancia del Ki67-LI. Una mujer de 71 años a la que se le diagnosticó un GI-NET con metástasis hepáticas y óseas y que realizó tratamiento médico, presentó cefalea, exoftalmos derecho y dolor de ojo derecho, y fue remitida a nuestro departamento. La imagen de resonancia magnética reveló que los tumores en la región occipital izquierda y la órbita derecha. Diagnosticamos como metástasis tumores cerebrales y orbitales de GI-NET. Se realizó la extirpación quirúrgica de ambas lesiones sintomáticas y se confirmó patológicamente el diagnóstico. Los estudios inmunohistoquímicos revelaron la discrepancia del Ki67-LI de las lesiones (tumor cerebral: 8% frente a tumor orbitario: 22%). El muestreo de múltiples focos metastásicos puede evitar que se subestime la actividad proliferativa del tumor (AU)

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.

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.

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.

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.

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.

Recurrent corneal hemangiosarcoma in a cat with subsequent extension into the orbit.

A 7-year-old neutered female Domestic Short-haired cat was presented for evaluation of ulceration and severe vascularization of the left cornea. Ophthalmic examination revealed a large red irregular mass over the whole cornea in the left eye. A lamellar keratectomy was performed. Histopathology revealed a chronic lymphoplasmacytic, histocytic, neutrophilic ulcerative keratitis with fibrosis and vascularization. The tumor recurred within 3 months, and another lamellar keratectomy and sclerotomy were performed. The lesion was diagnosed histopathologically as a hemangiosarcoma with incomplete margins. The mass recurred locally 6 weeks later, and an enucleation was performed. Histopathology revealed infiltration of the limbus and connective tissue beyond the sclera. Seven weeks later, a fluctuant swelling was found in the left orbit. Computed tomography confirmed a soft tissue attenuating mass measuring 33 x 24 mm diameter in the orbit. There was no sign of metastasis. Clinical remission was achieved with combined chemotherapy with doxorubicin and radiation therapy. The patient remained in clinical remission 20 months post-chemotherapy.
