Abstract
Ewing sarcoma (ES) is a highly aggressive bone and soft tissue tumor that occurs
mainly in young children and adolescents and is associated with primary and
metastatic disease. Intramedullary ES (either primary or secondary) is rare, and
the ideal management remains inconclusive. We herein report intramedullary and
extramedullary metastatic ES in a single patient. A 46-year-old woman was
referred to our outpatient clinic from the oncology clinic with progressive
paraparesis and paresthesia for 1 week prior to presentation. She had developed
left clavicular ES 2 years earlier for which surgery and chemoradiotherapy had
been performed. At the present evaluation, she was diagnosed with intramedullary
thoracic and lumbar extradural masses. Thoracic surgery was performed, and a
biopsy of the lesion was obtained. The diagnosis of ES was confirmed
histopathologically, and she underwent adjuvant chemotherapy. Her neurological
status did not improve after surgery, and she underwent rehabilitation and
physical therapy. The lumbar lesion resolved with chemotherapy. Metastasis of ES
to the spinal cord, especially intramedullary lesions, is extremely rare, and
there is no standard management guideline. However, surgical decompression and
adjuvant chemotherapy are the main treatments in these cases.

The Role of Neuroaxis Irradiation in the Treatment of Intraspinal Ewing Sarcoma: A Review and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14051209. [PMID: 35267515 PMCID: PMC8909708 DOI: 10.3390/cancers14051209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 02/13/2022] [Accepted: 02/22/2022] [Indexed: 12/04/2022] Open
Abstract
The role of cranio-spinal irradiation (CSI) for primary extraosseous intraspinal Ewing sarcoma (EwS) remains unclear. Here, we evaluate clinical and survival outcomes in patients with primary intraspinal EwS treated with CSI as part of multimodal primary therapy regimens. We abstracted patient information, including details on treatment application, efficacy, and tolerance from the literature and our hospital database for a cohort of 24 primary intraspinal EwS patients treated with CSI. Median age was 25.5 years, median CSI dose was 36 Gy and mean boost dose was 12.8 Gy. Sixteen patients (66.7%) achieved complete radiological remission, another 5 patients demonstrated partial response and 1 patient showed no response to treatment. Compared to a cohort of patients treated with focal radiotherapy, CSI patients were more likely to have multifocal disease at time of diagnosis (p = 0.001) and intradural tumor location (p < 0.001). Despite over-representation of these unfavorable characteristics, there was no survival difference between groups (p = 0.58). While CSI shows promising results in the treatment of primary intraspinal EwS, treatment should be considered individually based on tumor and patient characteristics in the absence of prospective trials.

Comparative analysis of magnetic resonance imaging and pathological findings of microcystic meningioma and meningeal Ewing sarcoma/peripheral primitive neuroectodermal tumors. Acta Neurol Belg 2021; 121:1607-1613.

Abstract
Microcystic meningiomas (MCMs) and meningeal Ewing sarcoma/peripheral primitive neuroectodermal tumours (pPNETs) are difficult to differentiate because of the similarity in their image manifestation on magnetic resonance imaging (MRI). Differential diagnosis of these two tumours before surgery could contribute to ameliorating clinical decision-making, and predicting prognosis. Here, we aimed to comparatively analyse the difference between MRI and pathological findings of these two tumours. Thirteen cases of MCM and eleven cases of meningeal Ewing sarcoma/pPNET confirmed through pathology were analysed retrospectively. The imaging features of the two tumours were statistically analysed using the Chi square test. The average age of patients with MCM and meningeal Ewing sarcoma/pPNET was 47 ± 18.4 years and 20 ± 13.2 years, respectively. Features of MRI, including tumour morphology, dural tail sign, bony destruction, and distant metastasis, were significantly different between the two tumours (p < 0.001). T1-weighted (T1W) signal and enhanced features resulted in a p value of < 0.05. There were no significant differences in the T2-weighted (T2W) signal and peri-tumoural oedema (p > 0.05). MCM immunohistochemistry showed that all the cases were positive for vimentin (Vim), epithelial membrane antigen (EMA), and the ki-67 index was less than 5%, while all the cases of meningeal Ewing sarcoma/pPNET were positive for Vim and CD99, and the ki-67 index was more than 30%. MRI imaging features of MCMs and meningeal Ewing sarcoma/pPNETs were different. Accurate preoperative diagnosis of these two tumours is helpful in implementing a clinical surgical plan and further management. Moreover, imaging combined with pathology can explain the imaging characteristics better.

Cervical intramedullary recurrent Ewing sarcoma after 10-year disease-free survival in an adult: a case report and review of literature. Spinal Cord Ser Cases 2021; 7:45. [PMID: 34045432 DOI: 10.1038/s41394-021-00406-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 05/13/2021] [Accepted: 05/13/2021] [Indexed: 11/10/2022] Open
Abstract
INTRODUCTION Intramedullary metastasis of Ewing sarcoma is extremely rare. Here, we report an adult case of cervical intramedullary recurrent Ewing sarcoma after a 10-year disease-free survival after the initial surgery for a thoracic lesion. CASE PRESENTATION A 39-year-old man with a history of surgery and chemoradiotherapy for thoracic Ewing sarcoma ten years ago presented with neck pain and incomplete motor paralysis in the right upper extremity, which had suddenly appeared three months before. Cervical magnetic resonance imaging revealed a tear-drop-shaped intramedullary lesion at the C3 level accompanied by diffuse edematous change. Because of the rapid progression of his myelopathy, he underwent surgery for this intramedullary lesion. Intraoperatively, the tumor exhibited an orangish exophytic appearance. The unclearness of the tumor boundary compelled us to perform a partial resection. The histopathology showed the tumor comprised small round atypical cells with immunoreactivity for Nkx2.2 and CD99, diagnosing a metastatic Ewing sarcoma. Postoperatively, although his myelopathy improved transiently and adjuvant chemotherapy radiation was undergone, he died of cranial dissemination of the tumor two months and a half later. DISCUSSION To our knowledge, 31 cases of primary and only 4 cases of recurrent intramedullary spinal Ewing sarcoma have been reported to date; however, this is the first case of recurrent intramedullary Ewing sarcoma with a 10-year disease-free survival. Sadly, the prognosis of the current case was extremely poor. There is no clear treatment guideline for recurrent intramedullary Ewing sarcoma because of its rarity, and further collection of similar cases would be required.

Abstract
Background Primitive neuroectodermal tumor (PNET) is a relatively rare malignant small round cell tumor, and the occurrence of cervical PNET during pregnancy is extremely rare. Case presentation A case of pregnancy complicated by PNET at our hospital was reported. A 19-year-old pregnant woman presented to the hospital due to multiple instances of vaginal bleeding during the first and second trimesters. She was initially considered for threatened abortion but was ultimately diagnosed with cervical PNET. No standard treatment plan has been developed for pregnant women with this tumor. After completing the necessary examinations, doctors cooperated with the patient and her family to develop a surgical treatment plan. The patient recovered well after surgery, but she refused radiotherapy and chemotherapy. After nearly 3 years of follow-up visits, the patient is alive with no signs of recurrence. Conclusions PNET during pregnancy is a rare but complex condition. It is necessary to devise an individualized treatment plan according to gestational age. Timely surgical treatment can significantly prolong the survival time of patients but may also lead to fetal loss and the inability to carry a pregnancy.

Abstract
BACKGROUND Ewing sarcoma is a neoplasm within the family of small round blue cell tumors and most frequently arises from skeletal bone. Primary involvement of the central nervous system in these lesions is extremely rare, with an incidence of 1%. OBSERVATIONS A case is presented of a 34-year-old man who presented with left facial numbness, multiple intracranial lesions, a lumbar intradural lesion, and diffuse spinal leptomeningeal involvement. A lumbar laminectomy and biopsy were performed, which revealed the diagnosis of extraskeletal Ewing sarcoma/primitive neuroectodermal tumor. The patient had a rapidly progressive clinical decline despite total neuroaxis radiation and multiple lines of chemotherapeutic treatments, eventually dying from his disease and its sequelae 6 months after diagnosis. LESSONS The authors' review of 40 cases in the literature revealed only 2 patients with isolated intraaxial cranial lesions, 4 patients with cranial and spine involvement, and an additional 34 patients with spine lesions. The unique characteristics of this patient's case, including his presentation with diffuse disease and pathology that included a rare V600E BRAF mutation, are discussed in the context of the available literature.
