World J Clin Cases 2024; 12:5431-5440. [PMID: 39156087 PMCID: PMC11238686 DOI: 10.12998/wjcc.v12.i23.5431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 06/06/2024] [Accepted: 06/26/2024] [Indexed: 07/05/2024] Open
Abstract
BACKGROUND Primary renal Ewing's sarcoma (ES) is extremely rare, and only two cases causing Cushing's syndrome (CS) have been reported to date. We report that the case of an 18-year-old patient is diagnosed primary renal ES with typical CS characterized by purple stripes, weight gain, and hypertension. CASE SUMMARY CS was first diagnosed by laboratory testing. A huge tumor was revealed in the kidney following an imaging examination. Moreover, brain and bone metastases were observed. After comprehensive treatment, primarily based on surgery, primary renal ES was pathologically diagnosed with a typical EWSR1-FLI1 genetic mutation through genetic testing. Furthermore, the glucocorticoid level returned to normal. By the ninth postoperative month of follow-up, the patient was recovering well. Cushing-related symptoms had improved, and a satisfactory curative effect was achieved. CONCLUSION Primary renal ES, a rare adult malignant tumor, can cause CS and a poor prognosis.

Abstract
Ewing's sarcoma family of tumors (ESFTs) are a group of small round cell tumors with common morphological and genetic features, including Ewing's sarcoma of bone, primary extra-skeletal Ewing tumors, extraosseous Ewing sarcoma (EES), and Askin tumors. EES presenting as a primary renal mass is an exceedingly uncommon aggressive tumor with limited reported cases in the literature and often mimics other renal malignancies on imaging. We present a case of a 31-year-old man presenting with left flank pain and abdominal fullness of short duration. Radiological imaging studies showed a large heterogenous mass from the left kidney, confirmed to be Ewing's sarcoma on post-operative histopathological examination (HPE) and immunohistochemistry (IHC) studies. Subsequent follow-up showed extensive metastatic disease. EES of the kidney has a nonspecific presentation and imaging appearance necessitating a multi-disciplinary approach comprising radiological imaging with a high index of suspicion, HPE, IHC, and molecular analysis for the correct diagnosis.

Abstract
Introduction We aim to share the experience of a single center in the management of eight cases of renal primitive neuroectodermal tumor (PNET) which are uncommon, aggressive tumors. The objectives were to study the presentation of the disease, the treatment offered and its outcomes, and the comparison of the treatment with published literature. Methods The single-center renal PNET data of all patients were retrospectively reviewed from 2011 to 2022. Renal PNET was seen in eight patients. Minimum follow-up period of 1 year was required. Results Male-to-female ratio was 7:1. The mean age was 26.5 years. All were locally advanced tumors on presentation. One patient had an inferior vena cava thrombus, one patient had metastases on presentation, and two patients had tumor extending to paranephric space. The diagnosis was made by histopathology supported by immunohistochemistry showing CD99 positivity. All patients were treated with radical nephrectomy, followed by chemotherapy in all and radiotherapy in three patients. Two patients expired at 3½ and 6 years after surgery, the remaining six are alive at a median follow-up period of 34.5 months. Conclusion Renal PNET is an uncommon renal tumor which is aggressive and requires multimodal therapy for prolonged survival.

Abstract
BACKGROUND Ewing's sarcoma (ES) is a neuroectodermal tumor that typically occurs in the bones and soft tissues of children and young adults. Primary renal ES is rare; only a few cases and a small case series have been documented, and only four cases involved primary renal ES in older people (> 65 years old). CASE SUMMARY Herein, we describe the radiological and pathological features of primary renal ES in an older person. A 76-year-old man complained of poor oral intake and was found to have a large cystic renal mass with indistinct margins on computed tomography. Ultrasound-guided biopsy revealed that the tumor contained small round blue cells. The patient underwent a right radical nephrectomy. The tumor cells showed diffuse membranous CD99, and nuclear friend leukemia integration 1 transcription factor and NK2 Homeobox 2. Fluorescence in situ hybridization revealed EWSR1 translocation. Postoperatively, 18F-fluorodeoxyglucose positron emission tomography revealed no evidence of metastasis. The patient was diagnosed with primary renal ES. Six months following the surgery, local recurrence and distant metastasis were observed. Primary renal ES is rare and often lethal in older individuals. The specific imaging findings are unknown, and treatment protocols have not been standardized. CONCLUSION This case report describes the radiological and pathological features of primary renal ES in an older person.

Abstract
Background Pediatric non-Wilms renal tumors (NWRTs), which comprise a small proportion of renal tumors, are a heterogeneous group of neoplasms with variable malignant potential, mortality, and response to treatment. We performed this study to determine the clinical characteristics, management and prognosis of children with Pediatric NWRTs. Methods Medical records of all patients (n = 139) treated for NWRTs over a 12-year period (2008.01–2019.10) at a single center were reviewed retrospectively. Results The histopathological groups of NWRTs included malignant rhabdoid tumor of the kidney (MRTK) (n: 30, 21.6%), renal cell cancer (RCC) (n: 26,18.7%), clear cell sarcoma of the kidney (CCSK) (n: 24,17.3%), congenital mesoblastic nephroma (CMN) (n: 21,15.1%), cystic nephroma (CN) (n: 16,11.5%), metanephric tumors (n: 12, 8.6%), renal angiomyoliporma (RAML) (n: 3, 2.2%), renal primitive neuroectodermal tumor (n: 2, 1.4%), renal hemangioma (n: 2, 1.4%), inflammatory myofibroblastic tumor (n: 2, 1.4%), ossifying renal tumor of infancy (ORTI) (n: 1, 0.7%). The distribution of all malignant NWRTs, including MRTK, CCSK, RCC and PNET, according to stage was as follows: stages I (n = 26), II (n = 16), III (n = 29), and IV (n = 11). The summary table shows the treatment offered to children with NWRTs. A total of 123 children were followed up for an average of 42 months. Sixteen children were lost to follow-up. Tumor-free survival was observed in 94 children. One patient who suffered from RCC is currently receiving targeted therapy and survives with the tumor. Twenty-eight children (22.8%) died. Conclusions Pediatric NWRTs comprise 19.1% of all renal tumors in our single center. Most NWRTs can readily be distinguished using a range of immunohistochemical markers. Molecular genetic profiling has allowed much progress in the understanding of this group of tumors, making diagnosis and classification less difficult. The mainstay treatment of malignant NWRTs, including MRTK, CCSK, RCC and PNET, is comprehensive treatment. The mainstay treatment of benign NWRTs, including RAML, CN, ORTI, CMN, metanephric tumors, and renal hemangioma, is surgical resection alone and when the tumor diameter is smaller than 7 cm and the tumor locates in one pole, NSS can be performed.

Abstract
INTRODUCTION Primitive neuroectodermal tumor (PNET) of the kidney is unusual in adults. These tumours are diagnosed mainly on histopathology and that too sometimes has limitations. With this study, we aimed to review our clinical and histopathological data of patients with renal PNET and reviewing the world literature. METHODS In this retrospective study, we reviewed our database from January 2006 to July 2018 to include all the cases of primary PNET of the kidney. We also performed systematic literature search to identify all the relevant series on renal PNET. RESULTS A total of 12 patients including 5 men and 7 women were managed during the above mentioned period. Out of these 7 patients, 2 patients had metastasis at diagnosis, one had locally advanced disease, 6 underwent radical nephrectomy, 5 patients received adjuvant chemotherapy (two currently receiving) and only 1 patient received adjuvant radiotherapy (RT). On Immunohistochemistry (IHC), CD99 and FLI1 were positive in all the patients. Median survival was 10 months. In our review 10 studies were included, 38.6% of the patients had metastatic disease and 10.7% had locally advanced disease at diagnosis. Overall mean survival was 33.75 months. CD99 and FLI1 were positive in 94.3% and 78.5%, respectively. CONCLUSION PNET remains a pathological diagnosis and IHC has important place in diagnosis of PNET. Locally advanced and metastatic disease is common at diagnosis leading to overall poor survival.

Abstract
The Ewing sarcoma family of tumors (ESFT) are high-grade small round blue cell malignancies traditionally presenting in children and adolescents. The most common site of primary disease is bone, though extraskeletal primary sites are well-recognized. We present 6 cases of primary ESFT of the kidney and 1 case of the adrenal gland. Patients were 11 to 18 years of age at diagnosis. Metastases at diagnosis were present in most cases (n=6). All patients underwent surgery, and most received radiation (n=5). Five patients relapsed after initial remission. Comprehensive review of the primary renal ESFT literature was used to analyze various factors, including age, sex, disease metrics, metastases at diagnoses, and overall survival in a total of 362 cases. Notably, while the general ESFT population has reported rates of metastasis at diagnosis of 20% to 25%, this rate in the renal ESFT population was 53% with a rate of 59% in adolescent and young-adult patients (11 to 24 y). Nodal disease at diagnosis was present in 24% of renal ESFT cases compared with 3.2% in patients with primary skeletal ESFT. While this malignant process may share histologic and molecular features with its bone and soft tissue counterparts, primary renal ESFT presentations seem to be more aggressive and have worse outcomes.

Abstract
Limited information exists on the clinical behavior of the Ewing sarcoma family of tumors (ESFT) of the kidney. We reviewed the records of 30 patients (aged 8-69 years) with ESFT of the kidney seen at our institution between 1990 and 2013. We analyzed the event-free survival (EFS) and overall survival (OS) for associations with patient demographics, disease group, tumor size, tumor thrombus, and treatment. Six patients (20%) had tumors confined to the kidney (Group I), seven (23.3%) had local tumor extension beyond the kidney (Group II), and 17 (56.7%) had distant metastasis at diagnosis (Group III). Twenty-five (83.3%) patients underwent radical (19 upfront, five delayed) or partial (one upfront) nephrectomy, 25 (83.3%) chemotherapy and four (13.3%) radiotherapy. The 4-year EFS and OS were 43% (95% CI, 26-61%) and 63% (95% CI, 46-81%), respectively. EFS and OS were significantly associated with disease group and chemotherapy (p < 0.039). The presence of tumor thrombus in renal vein and/or inferior vena cava was associated with worse EFS (p = 0.053). Patients with disease confined to the kidney treated with nephrectomy and adjuvant chemotherapy have favorable outcomes. Local tumor extension beyond the kidney, tumor thrombus, and distant metastasis are unfavorable factors that warrant intensification or novel approaches of therapy.

Abstract
Background/aim Non-Wilms renal tumors (NWRTs) are rarely encountered in children. The aim of this study is to determine the treatment strategies, prognosis, outcomes, and survival of children with NWRTs at Erciyes University in Kayseri, Turkey. Materials and methods Medical records of all patients (n = 20) treated for NWRTs over a 23-year period (1995–2018) were reviewed retrospectively. Results There was male predominance (female/male: 7/13); the median age at diagnosis was 3.2 years old (0.1–13.5 years old). The major histological groups included mesoblastic nephroma (MBN), (n: 5, 25%), malignant rhabdoid tumor (MRT), (n: 5, 25%), renal cell carcinoma, (n: 3, 15%), inflammatory myofibroblastic tumor (n: 2, 10%), multilocular cystic renal tumors (n: 2, 10%), metanephric adenoma (n: 1, 5%), renal neuroblastoma (n: 1, 5%), and bilateral renal Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET) (n: 1, 5%). All of the patients with NWRTs had radical nephrectomy except the child with bilateral renal ES/PNET. Six children died because of progressive disease; the mortality rate was 30% (n: 6). Conclusion We have made the first report of bilateral renal involvement of ES/PNET in the English medical literature. Physicians dealing with pediatric renal masses should be alert to the high mortality rate in children with MRT, MBN, and ES/PNET and they should design substantial management plans for NWRTs.

Abstract
INTRODUCTION Pediatric Ewing sarcoma (ES)/primitive neuro-ectodermal tumor (PNET) occurring in the genitourinary system has been rarely reported. And the result of long-term follow-up is still a matter of debate. OBJECTIVE The aim of the study was to identify the characteristics, therapeutic strategies, and long-term outcomes of pediatric ES/PNET in the genitourinary system. PATIENTS AND METHODS All children with genitourinary system PNET from a single center were retrospectively reviewed. The American Joint Committee on Cancer (AJCC) staging system was used to evaluate tumor grade. RESULTS Four patients were included. Three were boys, and 1 was a girl. The locations of the lesions were the penis in 1 patient, ureter in 1 patient, and kidney in 2 patients. Two patients were of AJCC stage IVB, and the other 2 patients were of stage IIA. In the follow-up ranging from 2.5 to 8.0 years, 3 patients had survival, and 1 patient died. The patient with penis PNET survived during the 8 years of follow-up. One patient with renal PNET had tumor thromboses in the renal vein, inferior vena cava, and right atrium, which was the first definite report in children (case 3). DISCUSSION Primitive neuro-ectodermal tumor as a highly malignant subgroup of blue round cell tumor is extremely rare in the genitourinary system, especially in children. The current case series represents the first report of penis PNET in children with the longest (8 years) follow-up and first definite report of pediatric renal PNET with vena cava and atrium tumor thrombus. In contrast to the previous literature, the patient with ureteral PNET in this study was much younger, who was the youngest child to be reported in the literature thus far. Although the key prognostic factor of the outcomes is detectable metastases at diagnosis, the patient with penis PNET and bone and lung metastasis in this series still survived. It was hypothesized from the data of present cases that young age was a protective factor, which was consistent with the previous literature. Aggressive therapy is not trivial for patients with multiple recurrences who can also be a long-term survivor. The survival outcomes of these high-stage patients were favorable with combination treatment. As the patient with penis PNET in this series had bone metastasis at his 7.5 years after definite diagnosis, five years of follow-up was not enough. The follow-up period should be extended, even to a lifetime follow-up. CONCLUSIONS Children with PNET have a better prognosis than adults. Aggressive combination treatment should be performed to improve prognosis and the survival rate. It is better to monitor the changes of the disease by extending the follow-up period.

Abstract
Renal Ewing sarcoma (RES) is an extremely rare disease. The standard treatment for this disease is lacking, and clinical experience needs to be accumulated. Here, we report a case of RES that rapidly developed to metastatic disease and was refractory to radiotherapy and chemotherapy; however, the case obtained a partial response based on Choi criteria by orally taking antiangiogenic drug apatinib. Our case suggests that apatinib may be a therapeutic option for RES.

Abstract
Primary Ewing sarcoma (ES) or primitive neuroectodermal tumour (PNET) is a rare tumour in adults and primary renal involvement is extremely rare. Patients with renal ES or PNET respond to and would benefit from conventional ES treatment according to ES study protocols. Here, we report a case of a young woman, presenting with right flank pain and haematuria. After ultrasound and CT evaluation, a right middle pole renal mass was detected. The patient underwent radical right nephrectomy, and a grade 4 ES with peritoneal involvement was documented. Subsequently, the patient underwent adjuvant chemotherapy for 5 months. Follow-up 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT scan demonstrated bilateral cervical, hilar, mediastinal and retroperitoneal FDG-avid adenopathies associated with mild right-sided pleural effusion with no metabolic activity, signifying the role of PET/CT scan in tumour restaging.

Abstract
OBJECTIVE: To identify important qualitative and quantitative clinical and imaging features that could potentially differentiate renal primitiveneuroectodermal tumor (PNET) from various subtypes of renalcell carcinoma (RCC). METHODS: We retrospectively reviewed 164 patients, 143 with pathologically proven RCC and 21 with pathologically proven renal PNET. Univariate analysis of each parameter was performed. In order to differentiate renal PNET from RCC subtypes and overall RCC as a group, we generated ROC curves and determined cutoff values for mean attenuation of the lesion, mass to aorta attenuation ratio and mass to renal parenchyma attenuation ratio in the nephrographic phase. RESULTS: Univariate analysis revealed 11 significant parameters for differentiating renal PNET from clear cell RCC (age, p = <0.001; size, p =< 0.001; endophytic growth pattern, p < 0.001;margin of lesion, p =< 0.001; septa within the lesion, p =< 0.001; renal vein invasion, p =< 0.001; inferior vena cava involvement, p = 0.014; enhancement of lesion less than the renal parenchyma, p = 0.008; attenuation of the lesion, p = 0.002; mass to aorta attenuation ratio, p =< 0.001; and mass to renal parenchyma attenuation ratio, p =< 0.001). Univariate analysis also revealed seven significant parameters for differentiating renal PNET from papillary RCC. For differentiating renal PNET from overall RCCs as a group, when 77.3 Hounsfield unit was used as cutoff value in nephrographic phase, the sensitivity and specificity were 71.83 and 76.92 % respectively. For differentiating renal PNET from overall RCCs as a group, when 0.57 was used as cutoff for mass to aorta enhancement ratio in nephrographic phase, the sensitivity and specificity were 80.28 and 84.62 % respectively. CONCLUSION: Specific qualitative and quantitative features can potentially differentiate renal PNET from various subtypes of RCC. ADVANCES IN KNOWLEDGE: The study underscores the utility of combined demographic and CT findings to potentially differentiate renal PNET from the much commoner renal neoplasm, i.e. RCC. It has management implications as if RCC is suspected, surgeons proceed with resection without need for confirmatory biopsy. On the contrary, a suspected renal PNET should proceed with biopsy followed by chemoradiotherapy, thus obviating the unnecessary morbidity and mortality.

Abstract
Primary Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET) of the kidney represents a spectrum of rare neoplasm with dismal clinical prognosis. This type of malignant tumor predominantly occurs in the soft tissue and bones of pediatric–young adults, and it may rarely arise from the kidney. Derived from the neuroectoderm, renal ES/PNET belongs to a group of primitive and aggressive tumors in its biological manifestation. Herein, we report the case of a 40-year-old pregnant woman with renal mass, in whom was found gross hematuria and slight lumbar acid during pregnancy. A computed tomography scan revealed an irregular soft tissue mass approximately 5×5×5 cm in size. The patient underwent robot-assisted laparoscopic nephrectomy of the right kidney after childbirth. The diagnosis of renal ES/PNET was confirmed by immunohistochemical detection and fluorescence in situ hybridization of the nephrectomy specimen. Primary renal ES/PNET represents a rare and lethal entity, especially in a 40-year-old pregnant woman. Although the clinical presentation of this tumor is nonspecific, renal ES/PNET frequently exert dismal prognosis and aggressive clinical outcomes. Thus, it is essential to distinguish ES/PNET from other renal cell carcinomas and carry out an optimum treatment strategy as soon as possible.

Abstract
We present a case of a 14-year-old girl who was diagnosed with Burkitt lymphoma in 2014. She was managed with chemotherapy and remained in remission for 3 years. On her surveillance imaging in 2017, a left-sided renal neoplastic mass was incidentally discovered. She underwent nephrectomy and pathology of the resected specimen revealed small cell tumour of the kidney with features favouring renal Ewing sarcoma/primitive neuroectodermal tumour. Molecular genetic analysis by fluorescence in situ hybridisation was performed which showed translocation of 22q12, thereby confirming the diagnosis. This is a rare secondary malignancy and an unusual association. This case highlights the importance and diagnostic dilemmas of rare secondary tumours in patients with such haematological malignancies and discusses its possible pathogenetic aspects.

Abstract
Malignant renal tumors account for 7% of childhood cancers, and Wilms tumors are by far the most common-but not in older children and adolescents. Among individuals in the latter half of their 2nd decade of life, renal cell carcinoma (RCC) is more common than Wilms tumor. The histopathologic spectrum of RCCs in children differs from that in adults. The most common subtype of RCC in children and adolescents is Xp11.2 translocation RCC, which is distinguished by hyperattenuation at nonenhanced computed tomography, a defined capsule, and associated retroperitoneal lymphadenopathy. Papillary RCC is the second most common histologic subtype. It enhances less intensely compared with the adjacent renal parenchyma and has a propensity for calcification. Clear cell RCC is seen in patients with von Hippel-Lindau disease and is distinguished by its relatively hypervascular nature. Medullary carcinoma affects adolescents with the sickle cell trait and is characterized by an infiltrative growth pattern and extensive metastasis at presentation. Angiomyolipoma is seen in children with tuberous sclerosis complex and is often multifocal and hypervascular, with macroscopic fat. Metanephric tumors are central, circumscribed, and typically calcified. Lymphoma usually manifests as multifocal masses, but it may involve a solitary mass or infiltrative pattern. Extensive adenopathy and involvement of the gastrointestinal tract or other organs also may be seen. Primitive neuroectodermal tumor is an aggressive neoplasm that is typically quite large at diagnosis. Knowledge of the clinical, biologic, and histopathologic features of renal tumors in older children and adolescents and their effects on the imaging appearance can help the radiologist offer a useful preoperative differential diagnosis.

Abstract
This is a 15-year-old female who presented with sudden onset left flank pain associated with nausea and vomiting and a history of weight loss. Radiological investigation revealed a large non-obstructive tumor involving the lower pole of the left kidney which was primarily thought to be a renal cell carcinoma. She underwent left open radical nephrectomy with adrenalectomy. Histopathology of the resected specimen showed features of Ewing's sarcoma of the kidney which was confirmed by cytogenetic analysis. This is a rare disease especially in the pediatric group and in reporting such a rare case we hope it helps in identifying a potential course of the disease and its response to the involved treatment.

Abstract
BACKGROUND Ewing sarcoma family of tumors (ESFT) of the kidney are exceedingly rare. Given the rarity of this neoplasm and the complexity associated with its management, information regarding treatment and outcome is warranted. MATERIALS AND METHODS We conducted a retrospective study of patients with ESFT of the kidney who were treated at MDACC between January 1, 2001 and January 1, 2011. Descriptive statistics were used. RESULTS Thirteen patients were identified (median age, 33 y; male:female 11:2). Common presenting symptoms were back pain, flank pain, and hematuria. Six patients had metastatic disease at presentation. Initial diagnostic biopsy was performed in 6 patients. Immunohistochemistry showed strong positivity for CD99 (mic2) and cytogenetic analysis demonstrated evidence of EWSR1 fusion gene in 8 cases. Nine patients underwent nephrectomy. Frequently used chemotherapy regimens consisted of vincristine, doxorubicin, and ifosfamide. Median overall survival was 17.2 months. Three patients were alive at the time of analysis, at 2, 7, and 11 years from diagnosis (the latter without evidence of disease). CONCLUSIONS Renal ESFT carry a guarded prognosis with limited response to therapy and short median overall survival. For patients with metastatic disease, diagnostic biopsy and sarcoma-based chemotherapy regimens are recommended as upfront therapeutic strategy. The role of nephrectomy in the metastatic setting is unclear. Future studies with novel therapies are needed.

Abstract
Ewing sarcomas/primitive neuroectodermal tumors (ES/PNET) of the kidney are rarely found high-grade malignant tumors, offering poor prognosis. Although established treatment guidelines for ES of kidney are scarce, a multi-modality treatment approached is typically implemented. Herein, we report a 14-year-old female patient with ES of right kidney. Post-nephrectomy disease recurrence was treated with chemotherapy (i.e., vincristine, doxorubicin and cyclophosphamide); marked reduction in tumor size (i.e., from 18.5 × 11.3 cm2 to 3.7 × 2.2 cm2; ~96% reduction in size) as per computed tomography images was observed. We present our treatment experience and review from the available literature.

Abstract
A 23-year-old male presented with a 3-month history of left purulent rhinorrhea, progressive nasal obstruction, and intermittent epistaxis. A fiberoptic examination revealed a large vascular polypoid mass completely filling the left nasal cavity. CT and MRI scans showed a large hypervascular mass involving the left nasal airway, maxillary antrum, and the anterior ethmoid cells. There was no bony erosion or contiguous spread, and the remaining sinuses, orbit, and cranial fossa were uninvolved. The patient underwent complete removal of the mass via an external lateral rhinotomy approach. The soft mass was large and vascular. A microscopic analysis revealed an undifferentiated tumor consisting of a solid sheet of small, round blue cells. Mitotic figures were also present. Immunohistochemically, the tumor cells were strongly positive for CD99. Molecular studies using a PCR confirmed the chromosomal translocation of FLI1 (exon 6). These findings were considered diagnostic for Ewing's sarcoma. Postoperatively, the patient was treated with combined chemotherapy and radiotherapy. Adjuvant chemotherapy consisting of vincristine, doxorubicin, and cyclophosphamide alternating with ifosfamide and etoposide (total: 7 cycles) was commenced. He also received radiation therapy for local control (total dose: 50.4 Gy). The patient is currently alive without any evidence of recurrence or metastasis.

Abstract
The purpose of the study was to analyze the computed tomography (CT) findings of primitive neuroectodermal tumor (PNET) of the kidney and correlate them pathologically. Ten cases of pathologically confirmed renal PNET were collected and retrospectively reviewed. The CT features that were analyzed include tumor size, shape, margins, density, nature of enhancement, presence of thrombosis, and metastasis, etc. These parameters were correlated with pathological findings and combined with literature review. The median age of the patients was 30 years. CT images showed solitary, large, ill-defined, irregular, or lobulated heterogeneous mass. Invasive growth toward the renal cortex and pelvis with renal cortical interruptions were seen in eight cases with one case exhibiting invasion that extended beyond the renal capsule with soft tissue seen in the perirenal fat pace. The tumors were confined to the kidney contour with enlargement of kidney in six of the cases. Cystic changes with mural nodules were detected in three cases. Eight cases showed persistent moderate enhancement during the nephrographic phase. Irregular septum-like structures were seen in four cases. Thrombosis was detected in eight cases. Lymph node metastasis was detected in eight cases with bilateral lung metastasis in two and bone metastasis in one. Renal PNET is a rare highly aggressive disease affecting younger people. It should be considered as a strong differential when well confined, yet large tumors that cause enlargement of the kidney are seen and also when tumors expressing cystic changes along with mural nodules are seen. Although renal PNET has certain other characteristic CT features, pathological and immunohistochemistry report must also be sought for definitive diagnosis.

Abstract
Ewing sarcoma/primitive neuroectodermal tumor of the kidney (ES/PNET) is a member of Ewing’s sarcoma family, occurring in young adults. The clinical course and prognosis of ES/PNET are different from renal cell carcinoma (RCC). For definite diagnosis, in addition to cytogenetic analysis; other techniques may be needed; such as fluorescent in situ hybridization (FISH), reverse transcriptase-polymerase chain reaction (RT-PCR) of the t (11; 22) translocation [1].
Introduction Ewing sarcoma/Primitive neuroectodermal tumor of the kidney (ES/PNET) is a member of Ewing’s sarcoma family, occurring in young adults and has aggressive clinical behavior and poor prognosis. However, its discrimination from the renal cell carcinoma (RCC) is very difficult preoperatively. We present three cases of this rare disease that were managed in two academic centers. Presentation of cases Herein we report three cases of ES/PNET of the kidney, 2 young men complaining of right flank pain and gross hematuria and one young woman complaining of left subcostal pain. In two cases computerized tomography (CT) scan revealed huge renal masses which were excised by radical nephrectomy. Microscopic examination of the nephrectomy specimen showed primitive neuroectodermal tumor features which confirmed by immunohistochemistry (IHC). Two of 3 patients were treated with adjuvant chemotherapy and the third patient with neoadjuvant chemotherapy. They were symptom-free until now. Discussion The clinical course and prognosis of ES/PNET are different from renal cell carcinoma (RCC) and definite pathologic diagnosis is necessary for optimum treatment. For definite diagnosis, in addition to cytogenetic analysis; other techniques may be needed; such as fluorescent in situ hybridization (FISH), reverse transcriptase-polymerase chain reaction (RT-PCR) of the t (11; 22) translocation or the EWS-FLI and related gene fusions [1]. Conclusion Up to our knowledge and search in English literature, this is the first case series that was reported from a major referral center from our country, Iran.

Abstract
Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET) of the kidney is extremely rare, and is usually diagnosed after nephrectomy without neoadjuvant chemotherapy. Although ifosfamide and etoposide improve survival to a great extent in ES/PNET, the use of nephrotoxic agent, particularly ifosfamide, is a concern after nephrectomy. We describe the case of a 14-year-old female patient with abdominal mass who was diagnosed with ES/PNET of the right kidney after nephrectomy. Adjuvant chemotherapy including ifosfamide and etoposide were given. The estimated glomerular filtration rate decreased to 75% after the end of therapy. There was no evidence of recurrence 70 months after initial diagnosis.

Abstract
BACKGROUND Ewing sarcoma (EWS) of the head and neck is rare. Multimodal treatment consists of chemotherapy and local treatment; however, local treatment for EWS of the head and neck is challenging. The first objective was to describe local treatment administered to the patients with localized EWS of the head and neck according to the EURO-E.W.I.N.G.99-trial, and to assess the impact on survival. The second objective was to systematically review the scientific literature available for this topic. PROCEDURE Fifty-one patients were included. Local control consisted of surgery and/or radiotherapy (RT). Event-free survival (EFS) and overall survival (OS) were determined. Outcome was analyzed by comparing local treatment approaches. A Medline search was performed for EWS of the head and neck. RESULTS Eighty-six percent of patients had localized disease. Most common primary sites included the skull (45%), maxilla (14%), and mandible (12%). Three-year EFS was 74% and 3-year OS was 87% for patients with localized disease. EFS was 40% for patients >15 years compared to 81% for patients <15 years. Local control consisted of surgery (S; 33%), RT (18%), or S + RT (45%). Related 3-year EFS was 81% (S), 80% (RT), and 72% (S + RT); 3-year OS was 80%, 76%, and 81%, respectively. CONCLUSIONS In patients with EWS of the head and neck, age, and stage are important prognostic factors. Although not statistically significant, large tumor volume seems to be a negative prognostic factor. No difference in EFS and OS could be found when comparing patients treated with surgery, RT, or combined surgery and RT.

Abstract
Peripheral primitive neuroectodermal tumor/Ewing's sarcoma (pPNET/EWS) is an aggressive type of sarcoma that is rarely observed in the kidney. pPNET of the kidney principally occurs in young patients (<50 years old) and is very rare in older patients (≥50 years old). Additionally, only six cases of pPNET of the kidney have been reported in the literature in older patients (≥50 years old), and pPNET as a secondary primary tumor has rarely been reported. The current study presents a case of renal pPNET in a 51-year-old female who had been surgically treated for breast carcinoma and administered with adjuvant chemotherapy five years prior to hospitalization for pPNET. A computed tomography scan identified a tumor in the lower pole of the right kidney, which was treated by nephrectomy. Immunohistochemistry demonstrated diffuse, strong membranous positivity for cluster of differentiation (CD)99, positive nuclear staining for friend leukemia integration 1, and negative staining for Wilms' tumor 1 and other markers. Fluorescence in situ hybridization (FISH) analysis of the EWS breakpoint region 1 (EWSR1) demonstrated the characteristic EWSR1 translocation. The patient declined chemotherapy or radiotherapy but accepted traditional Chinese medicine. No evidence of recurrence was observed eight months after diagnosis. Only two cases of renal pPNET with a history of an earlier or synchronous primary cancer were reported in the literature from the USA and Germany, respectively. To the best of our knowledge, the present case is the first FISH-confirmed renal pPNET in an older patient following breast adenocarcinoma.

Abstract
Ewing sarcoma and primitive peripheral neuroectodermal tumor (PNET) are high-grade malignant tumors typically found in children and adolescents. These tumors belong to the family of small round cell tumors and are of neuroectodermal origin. Primary Ewing sarcoma of the kidney is rare and because of that is an infrequent differential diagnosis in urologic malignancies. Renal PNET mostly presents with nonspecific symptoms such as hematuria and abdominal pain. The imaging findings are uncharacteristic. The diagnosis is based on the histology, immunohistochemistry, and molecular pathologic findings. Once PNET has been diagnosed, multimodal treatment is indicated. Despite all treatment options, the prognosis of those with metastatic disease is poor.
