Abstract
CONTEXT.— Wilms tumor (WT) in adult patients is rare and has historically been a diagnostic and therapeutic conundrum, with limited data available in the literature. OBJECTIVE.— To provide detailed diagnostic features, molecular profiling, and patient outcomes in a multi-institutional cohort of adult WT patients. DESIGN.— We identified and retrospectively examined 4 adult WT cases. RESULTS.— Two patients presented with metastatic disease, and diagnoses were made on fine-needle aspiration of their renal masses. The aspirates included malignant primitive-appearing epithelioid cells forming tubular rosettes and necrosis, and cell blocks demonstrated triphasic histology. In the remaining 2 cases, patients presented with localized disease and received a diagnosis on resection, with both patients demonstrating an epithelial-predominant morphology. Tumor cells in all cases were patchy variable positive for PAX8 and WT1 immunohistochemistry. Next-generation sequencing identified alterations previously reported in pediatric WT in 3 of 4 cases, including mutations in ASXL1 (2 of 4), WT1 (1 of 4), and the TERT promoter (1 of 4), as well as 1q gains (1 of 4); 1 case showed no alterations. Three patients were treated with pediatric chemotherapy protocols; during follow-up (range, 26-60 months), 1 patient died of disease. CONCLUSIONS.— WT is an unexpected and difficult entity to diagnose in adults and should be considered when faced with a primitive-appearing renal or metastatic tumor. Molecular testing may help exclude other possibilities but may not be sensitive or specific because of the relatively large number of driver mutations reported in WT.

Abstract
Wilms tumor (WT) occurring in adults is rare and even much more rarely found to coexist with pregnancy. Clinical outcome in adults is worse overall compared with pediatric patients with WT and is often misdiagnosed with no standardized protocols for care guided by high-evidence clinical trials. We present a case of a 23-year-old woman diagnosed with WT who was found to be pregnant immediately following nephrectomy. Workup findings showed that she had disseminated disease but was successfully managed in a multidisciplinary team setting with modified intrapartum chemotherapy followed by postpartum chemotherapy. In low-resource settings, management protocols for adult patients with WT can be individualized by multidisciplinary teams to leverage available resources for best outcomes.

Abstract
Background: Wilms' tumor, nephroblastoma, is an extremely uncommon kidney tumor of adulthood. We reported a woman with a huge kidney mass diagnosed with nephroblastoma. Case presentation: A 39-year-old female was assessed due to right flank pain. CT scan revealed a mass measuring 128×100 mms involving the upper portion of the right kidney. The patient underwent nephrectomy, and the diagnosis of adult Wilms' tumor was confirmed based on the morphological and immunohistochemical findings. Conclusion: In adult patients with flank pain and renal mass, the diagnosis of Wilms' tumor should be pronounced in the absence of histopathologic features of renal cell carcinoma.

Abstract
Wilms' tumor (WT) in adults is a rare neoplasm. Only a few reports are available in the literature. The tumor often masquerades as renal cell carcinoma (RCC). For accurate reporting, histopathological examination (HPE) plays a vital role in early diagnosis and prompt administration of multimodality treatment helps to improve the prognosis. We comprehensively analyzed five cases of adult WT presenting in the third to fifth decade with flank pain, hematuria, fever, and palpable lump. After complete clinical, biochemical, radiological, and HPE evaluation, tumor was staged and treatment was planned accordingly. Patients with low-stage WT were treated with open radical nephrectomy and chemotherapy. One of the patients diagnosed with inferior vena cava (IVC) thrombus apart from the above treatment also underwent IVC thrombectomy. Another young male presenting with distant metastasis (stage IV) and focal anaplasia on histology received preoperative chemotherapy and then planned for surgery. Unfortunately, the tumor being unresectable, second-line chemotherapy was given but he ultimately succumbed to death. All other patients are on regular follow-up and disease-free. Adult nephroblastoma is a rare clinical entity with hostile behavior. The presence of IVC thrombus is not a contraindication to surgery. Although the management strategy as per pediatric protocol by the inclusion of multimodality approach improves survival, still the overall prognosis in adults is dismal. There is a need for a standardized treatment protocol to encourage a homogenous approach for this rare disease and thereby improve survival.

Abstract
Background Wilms’ tumor (WT) is the most frequently occurring paediatric renal tumor and is one of the most treatment-responsive tumors. A tumor-suppressor gene and other genetic abnormalities have been implicated in its etiology. In addition, patients with many congenital anomalies, such as Beckwith-Wiedemann syndrome, WAGR syndrome and Denys-Drash syndrome, have an increased risk of WT. Methods and results Two large collaborative groups – National Wilms Tumor Study Group (NWTSG)/Children's Oncology Group (COG) and The International Society of Paediatric Oncology (SIOP) have laid down the guidelines for standardized treatment of WT, though differing in the diagnostic and therapeutic approach. The major difference in the two guidelines is the timing of surgery: SIOP recommends using preoperative chemotherapy and NWTSG/COG prefers primary surgery before any adjuvant treatments. Both these groups currently aim at intensifying treatment for patients with poor prognosticators while appropriating the therapy to reduce long-term complications for those with favourable prognostic features. As the survival rate has now reached 90%, the primary objectives of the physician are to perform nephron-sparing surgery in selected cases and to reduce the dosage and duration of chemotherapy and radiotherapy in appropriate cases. The purpose of this review is to present current standards of diagnosis and treatment of WT around the world. Conclusion Further studies in future should be done to highlight the use of chemotherapy and radiotherapy under risk-stratified strategies. Further improvement in survival of these children can only be achieved by increasing awareness, early recognition, appropriate referral, and a multidisciplinary approach. o Most of the patients with WT have good prognosis. o Multimodality treatment and multidisciplinary care are the major contributors for an improved prognosis. o Further studies should be done on usage of chemotherapy and radiotherapy under more accurate risk-stratified strategies and to decrease the late effects of surgery.

Abstract
Wilms tumor is extremely rare in adults. There is no standard treatment for Wilms tumor in adults, and the therapy protocols are based on those used in children. Here, we report a case of Wilms tumor in a 24-year-old woman who was effectively treated with apatinib, a small-molecule inhibitor of vascular endothelial growth factor receptor-2. The favorable outcome suggested that antiangiogenic therapy might be effective in treating adults with Wilms tumors. Starting with this case, we reviewed the features of Wilms tumors in adults and its treatment with antiangiogenic therapy. The information in this review could provide a novel approach to treating adults with Wilms tumors.

Abstract
Wilms' tumour, a renal malignancy, primarily occurs in children with a peak incidence between 2 to 5 years age group and accounts for approximately 95% of childhood renal malignancies. Though rarely, it may also occur in adults with an incidence rate of less than 0.2 per million per year. Microscopically, there is no difference between Wilms' tumour of paediatric and adult age groups. But the prognosis for adults with Wilms' tumour is thought to be worse than that for children possibly due to more aggressive clinical course in case of adult Wilms' tumour. They are often associated with higher tumour stage at the time of presentation and outcome is often worse than paediatric age group possibly due to difficulty in diagnosis, inappropriate staging, and lack of standard treatment protocol. We report a case of 28-year-old lady presented with flank pain and abdominal lump. Abdominal CT scan showed a right renal mass suggestive of malignancy. A provisional diagnosis of renal cell carcinoma was made based on clinical and radiological findings. Nephrectomy was performed and a final morphological diagnosis of Wilms' tumour was given. Immunohistochemical study showed strong Wilms' Tumour 1(WT1) positivity in both blastemal and epithelial components confirming the morphological diagnosis. In view of its diagnostic difficulty and rare occurrence in adults, this case is being reported.

Abstract
BACKGROUND Only few previous case reports have been found focusing on the imaging findings of adult Wilms' tumor (WT). PURPOSE To characterize multislice computed tomography (MSCT), magnetic resonance imaging (MRI) characteristics, and follow-up results of adult WT. MATERIAL AND METHODS Sixteen patients with WT were studied retrospectively. MSCT and MRI were undertaken to investigate the tumor characteristics. RESULTS Tumors (mean diameter, 13.1 ± 4.5 cm) exhibited an expansible appearance and disrupted the reniform contour (16/16), cystic components (16/16), curvilinear calcification (1/16), poorly marginated (2/16), hemorrhage (16/16), displacement of renal pelvis or calyx (13/16), and had lymph node or distal metastases (5/16). Attenuation of WT was less or equal compared to renal parenchyma on unenhanced CT (P > 0.05), while tumor enhancement after administration of a contrast agent was lower than that of normal renal parenchyma (P < 0.05). WT was isointense on T1-weighted (T1W) imaging, isointense or hypointense on T2-weighted (T2W) imaging. Tumor enhancement was less than normal renal cortex in all phases (P < 0.05). The number of tumor stages (grades I, II, III, and IV) was two, three, six, and five cases, respectively. Follow-up time was in the range of 19-123 months; six patients died within 3 years, six patients died within 5 years after the initial diagnosis, with the remaining patients still alive. CONCLUSION Adult WT tends to be a large tumor, isointense or hypointense on T2W imaging with enhancement less than normal renal parenchyma in all phases. The long-term follow-up results demonstrated the poor prognosis of the tumor.

Abstract
Wilms' tumour (nephroblastoma) is the most common renal tumour in children. Wilms' tumour in adults is extremely rare and has a poorer prognosis than paediatric Wilms' tumour. It is difficult to differentiate adult Wilms' tumour from renal cell carcinoma based on radiological findings alone. The diagnosis in adults is often serendipitous following nephrectomy for presumed renal cell carcinoma. Because of the paucity of literature, there are no standard protocols for the management of adult Wilms' tumour, and therefore, it is managed as per paediatric Wilms' tumour. Herein, we report the case of adult Wilms' tumour in a 43-year-old man, which was diagnosed unexpectedly following nephrectomy for presumed renal cell carcinoma.

Abstract
Wilms' tumour is rare in adults, and spontaneous rupture with retroperitoneal hemorrhage as the presenting sign of renal tumour is also uncommon. We present a case of a 20-year-old woman with spontaneous rupture of Wilms' tumour by describing the course of diagnosis and treatment. The patient underwent an open left radical nephrectomy, and was treated with 18 weeks of adjuvant chemotherapy with vincristine and actinomycin D. The follow-up of 12 months demonstrated no recurrence. We also reviewed the limited number of related reports. These suggest that the preoperative diagnosis of adult Wilms' tumour is very difficult, and radical nephrectomy and postoperative comprehensive therapy are equally important in the treatment of these patients. Factors of prognosis for adults with Wilms' tumour include tumour stage, histopathology, and time and type of therapy.

Abstract
Wilms tumor (WT) is the most common neoplasm of the kidney in children. It is an embryologic tumor that histologically mimics renal embryogenesis and is composed of a variable mixture of stromal, blastemal, and epithelial elements. Nephrogenic rests, generally considered to be precursor lesions of the WT, are foci of the embryonic metanephric tissue that persist after the completion of renal embryogenesis. These are classified as perilobar and intralobar based on their location and maybe present as single or multiple foci. Intralobar and perilobar rests and the tumors arising from these rests differ morphologically and are characterized by 2 different sets of genetic abnormalities involving 2 adjacent foci, WT1 and WT2, on the short arm of chromosome 11. WTs arising in the intralobar rests tend to be stromal predominant and have a mutation or deletion of WT1. Germline mutation in WT1 may be associated with syndromic conditions such as WAGR and Denys-Drash syndromes. Perilobar rests and their corresponding tumors usually have loss of imprinting/loss of heterozygosity involving WT2, which contains several parentally imprinted genes. Loss of function of these genes, if present constitutionally, may be associated with Beckwith-Wiedemann syndrome or may result in isolated hypertrophy. Abnormalities in several other genes may also be seen in WT. These include WTX, (on chromosome X), CTNNB1 (chromosome 3), and TP53 (chromosome 17) among others. WT with loss of heterozygosity at 1p and 16q may have poor prognosis, requiring aggressive therapy. Treatment modalities for WT have evolved over many decades, primarily through the efforts of Dr J Bruce Beckwith at National WT study. This work is now being carried out by Children Oncology Group in North America and International Society of Pediatric Oncology in Europe. Although their therapeutic approaches are somewhat different, both have reported excellent results with equally high cure rates.

Abstract
Although nephroblastoma is the commonest renal tumor of childhood, it is rare in adults. In cases of predominantly epithelial type occurring in adulthood, it might be difficult to distinguish it from papillary renal cell carcinoma and metanephric adenoma. Here, we report three cases of adult epithelial nephroblastoma in 24-, 76-, and 21-year-old females. Histologically, the tumors were composed of papillotubular architectures of small and uniform tumor cells with high nucleocytoplasmic ratio without blastemal element. Immunohistochemically, the tumor cells were positive for WT-1 and CD57 but negative for AMACR, which was helpful to exclude the possibility of papillary renal cell carcinoma. Metanephric adenoma is a benign tumor, which can be distinguished by the observation of the cellular atypism and growth pattern. However, nephroblastoma with predominant epithelial element mimics the malignant counterpart of metanephric adenoma, that is, “metanephric adenocarcinoma.”

Abstract
Adult Wilms' tumor (WT) is a rare entity with less than 300 cases reported to date in the medical literature. Histologic and cytologic features of adult WT of the kidney are similar to findings in pediatric WT. While the lungs are noted to be the most frequent site of metastatic disease in the pediatric population, the incidence of lung metastases remains unknown for adult WT. A search revealed 38 cases of adult WT with lung metastases published to date in the English literature. Amongst these cases only two have utilized cytology of the lung lesions as a means to arrive at a final diagnosis. We report a case of adult WT metastatic to the lung that was initially diagnosed using endobronchial ultrasound-guided fine needle aspiration biopsy. The aim is to compare the current cytologic and immunohistochemical findings with those cases previously published, to outline the cytologic features of adult WT metastatic to the lung, and to emphasize the significance of cytologic diagnosis in the work-up of adult WT.

Abstract
INTRODUCTION Wilms' tumour is one of the commonest malignant tumours of childhood. It appears mainly in the first 5 years of life. Incidental examples of nephroblastoma in adults have been described in literature (about 3% of all described cases). There are diagnostic and therapeutic difficulties in that older age group. The preoperative diagnosis of nephroblastoma in adults is difficult because there are no specific radiographic findings that allow to distinguished it from the more common adult renal tumors. Histopathologically, there is no difference between adult and childhood Wilms' tumor. MATERIALS AND METHODS The PubMed database and current literature search was conducted for reports on clinical and histopathological features of nephroblastoma in adults. We also reviewed the literature in terms of treatment strategy, toxicity and prognostic factors. RESULTS Up till now, several biological factors have been identified that may be in future new prognostic factors. Modern treatment regiments improved OS in this group of patients (OS rates of 90%). The prognosis remain still worse for about 25% of patients with anaplastic, bilateral and recurrent disease. CONCLUSIONS Due to the fact that nephroblastoma is a very rare type of cancer, adult patients should be treated in an individual way based on the available schemes used in children. Toxicity in adults is higher than in children.

Abstract
Wilms' tumor (nephroblastoma) is extremely rare in adults, skeletal metastasis being still rarer. The clinical course of adult Wilms' tumor is very aggressive. The present case is a rare blastemal predominant adult Wilms' tumor presenting with skeletal metastasis. We report a case of 19-year-old female presented with severe low backache and colicky left loin pain of 3 months and progressive weakness of 15 days duration. Magnetic resonance image (MRI) of lumbosacral spine was reported as spinal metastasis with right renal mass. The patient underwent right radical nephrectomy and the tumor was histopathologically confirmed as adult Wilms' tumor. In case of adult Wilms' tumor, distant metastasis may be the first presentation and this possibility should be considered when an adult patient presents with flank pain and a renal mass.

Abstract
PURPOSE To compare the characteristics and outcome of adults and children diagnosed with Wilms' tumor. METHODS The Surveillance, Epidemiology and End Results (SEER) database was analyzed for patients diagnosed with Wilms' tumor between 1973 and 2007. Patients were stratified into pediatric (<16 years) or adult (≥16 years) groups. Overall survival was the primary endpoint. RESULTS A total of 2342 patients (2190 pediatric and 152 adult) with Wilms' tumor were identified. Adult patients were statistically more likely to be staged as localized than pediatric patients (62.5% vs 44.7%), to not receive any lymph node sampling (57.9% vs 16.2%), and to not receive any radiation treatment (74.3% vs 53.9%). Adults had a statistically worse overall survival (OS) than pediatric patients (5-year OS, 69% vs 88%, P<.001) despite the earlier tumor stage. When stratified by treatment era, the OS of all patients treated after 1981 was statistically higher than those treated before (5-year OS, 75% vs 89%, P<.001). Significant predictors of OS on univariate analysis for adults included treatment era, SEER stage, surgery, and radiation treatment. Significant predictors of OS on multivariate analysis of all patients included adult status (hazard ratio, 4.14; P<.001), treatment era, SEER stage, and surgery. CONCLUSION Adults in the SEER database had statistically worse OS than pediatric patients despite previous studies showing comparable outcome when treated on protocol. The worse outcome of SEER adults likely stems from incorrect diagnosis, inadequate staging and undertreatment. We recommend lymph node samplings for all adult Wilms' tumor patients and collaboration with pediatric oncologists.

Abstract
INTRODUCTION Wilms' tumour (WT) is very rare in adults but very common in children. Treatment guidelines for adult patients with WT are still insufficient. Some study groups recommend that therapeutic protocols for adults with WT (AWT) should follow the guidelines that have been established for children. OBJECTIVE To describe the clinical and pathological characteristics of AWT as well as the treatment protocols and outcomes for AWT at our treatment centre. MATERIAL AND METHODS Seven patients (5 females and 2 males) were diagnosed with AWT in our hospital between 2002 and 2009. The tumours were staged and the patients were treated according to the paediatric regimen recommended by the National Wilms' Tumor Study Group. RESULTS The median patient age at the time of diagnosis was 29 years (range, 16-37 years). Flank pain was the most common clinical presentation. One patient was in Stage I of disease development, two were in Stage II, two were in Stage III and two were in Stage IV. Anaplasia was present in 3 patients with Stage III or Stage IV disease. All of the patients but one underwent nephrectomy and 2 incomplete surgeries were performed. Seven patients received 2-drug or 3-drug chemotherapy (dactinomycin and vincristine and/or doxorubicin). Two patients with Stage III disease also received radiation therapy (a total dose of 3600 or 3960 cGy). Complete remission was achieved in 4 patients. Three patients (one with Stage III disease, 2 patients with Stage IV disease) died of their disease and those patients were all classified with an unfavourable histological type called anaplasia. With a median follow-up of 53.5 months (range, 40-102 months), the 3-year and 5-year overall survival rates were 57.1% (95% confidence interval, 20.4-93.8%). CONCLUSIONS The results of this report suggest that histological anaplasia might be an adverse prognostic factor for AWT. Proper application of the diagnostic and therapeutic regimens established for children may improve the prognosis of adult patients with WT.

Abstract
Background. The most common renal tumors in adults is renal cell carcinoma. Wilms’ tumor in subjects older than 16 years is rare; only 3% of Wilms’ tumors are reported in adults, which explain the difficulties in diagnosis and treatment of this tumor entity in this age group. Methods. Patient with stage IV adult nephroblastoma with favorable histology was described, current treatment modalities were discussed, and the literature was reviewed. Results. Nineteen year old female patient is presented with renal mass, abdominal lymphadenopathy, and bilateral pulmonary deposits. Sonar guided biopsy from the renal mass was taken and pathology revealed nephroblastoma. Right nephrectomy was performed and the pathological examination revealed classic histology of nephroblastoma. The case diagnosed as stage IV adult Wilms’ tumor with favorable histology. According to National Wilms’ Tumor Study Group (NWTS-3), multimodal therapy was initiated immediately after surgery. The patient failed to respond to the first line therapy and died due to disease progression. Conclusion. Adult Wilms’ tumor has no specific guidelines and this may lead to improper or incorrect treatment.

Abstract
Wilms’ tumor is rare in adults. Though the approach to diagnosis and treatment of adult Wilms’ tumor (AWT) is closely modeled on recommendations for childhood Wilms’ tumor, views differ on how aggressive the treatment should be. We report a case of a 37-year-old with Stage III favorable histology AWT. A radical nephrectomy was performed and the patient was due for chemotherapy. Recent advances, controversies and current recommendations in the treatment of AWT are discussed.

Abstract
We report the case of a 43-year-old woman with adult Wilms' tumor. Imaging studies confirmed the presence of a 25 x 20 x 12 cm mass in the left kidney. A radical transabdominal nephrectomy was performed. Histological diagnosis was adult Wilms' tumor. Postoperative chemotherapy was offered to the patient who remains disease-free 67 months postoperatively. There are a few reported cases of this entity and till today the best treatment options and the prognosis remain unclear.

Abstract
Background Wilms' tumor is the commonest primary malignant renal tumor in childhood. Rarely, it may present in the adult age group. Case presentation We report a 48-year-old male presenting with flank pain and haematuria. Abdominal ultrasound revealed a right renal mass measuring 11 × 10 cms, and a clinical diagnosis of renal cell carcinoma was made. Nephrectomy was performed, and a final diagnosis of adult Wilms' tumor was made based on the criteria proposed by Kilton et al. Conclusion The possibility of an adult Wilms' tumor should be considered when a patient presents with pain in the flank and a renal mass. Rarity of the tumor favors documentation in literature.

Abstract
A unique case of Wilms' tumor with monophasic epithelial histology in the bone metastasis at initial presentation in an 18-year-old Taiwanese girl is presented. Histologically, a purely differentiated epithelial component in the L1-3 vertebrae was noted, which is consistent with the epithelial component in primary Wilms' tumor of the kidney by both microscopy and immunohistochemistry. Hence, Wilms' tumor should be included in the differential diagnosis of a metastatic lesion presenting a purely epithelial histology in a young adult or a child.

Abstract
Wilms' tumor is a malignant embryonic renal neoplasm that is exceptional in adults. There are not clinical data or radiographic investigations that can distinguish it from renal cell carcinoma. So the diagnostic is based in the pathological evaluation. It may be cystic and must be consider in the differential diagnosis of cystic lesions of the kidney. The prognosis of Wilms' tumor in adults is worse than in children because of the high recurrence, the lower response rate to chemotherapy regimens and the advanced stage at the time of clinical presentation, like an asymptomatic abdominal mass in 75% of the cases. We report a new case of nephroblastoma in a 29 years old woman presenting like a renal colic, with a cystic configuration by abdominal ultrasound initially, that changed into a solid renal mass later. There is not a definitive treatment protocol currently but some authors suggest a combination chemotherapy with carboplatin and etoposide because it is very effective in recurrent or refractory adult Wilms' tumor. Our patient remains asymptomatic and without evidence of recurrence 18 months after the surgery.

Abstract
The fine-needle aspiration cytologic findings of Wilms' tumor occurring in a 20-yr-old female patient and a 35-yr-old male patient showing blastemal, spindled sarcomatous and rare epithelial components are reported. The male patient had the typical presentation of renal mass with metastasis to lung and pleura, whereas the female patient had an unusual presentation with the tumor originated from the subcapsular nephrogenic zone of the kidney, extending into the liver without invasion into the renal cortex. Cytogenetic analysis of this case identified: 90, XXXX, +2x3-4, -5, -15, -16, -17, -17, i (17)(q10) x2. This finding may represent a genetic change associated with Wilms' tumor of older pediatric and young adult patients. To the best of our knowledge, this case is the sixth case with cytogenetic study and the first case revealing isochromosome 17q of an adult Wilms' tumor.

Abstract
OBJECTIVE Wilms' tumor or nephroblastoma is the most common renal tumor of childhood. The incidence in adults is rare, estimated at about 1% of all cases and approximately 200 cases have been described in the world literature. We report a new case of adult Wilms' tumor and realize a short review. METHODS/RESULTS We describe a case of Wilms' tumor in a young male, aged 15 years, with associate genitourinary abnormalities. The patient underwent radical nepherctomy with postoperative chemotherapy. CONCLUSIONS The Wilms' tumor in the adult population is exceptional, and the definitive diagnostic is based in the findings of the pathological analysis. The application of therapeutic protocolos for children to adults offers an smaller percentage of cure and poorer prognostic. Therapheutic protocolos more aggressive are necessary for increase the worse prognostic in the adult, but because of the rarity is difficult to define the most effective form of treatment.

Abstract
The authors report three nephroblastoma's cases occurred in adult and treated at Ibn Rochd Oncology Center at Casablanca. The average of age was 24 years (19-29 years) and the delay of diagnosis was five months (3-8 months). The most frequent clinical sign was a lumbar fossa mass. At diagnosis, radiological exams revealed that patients presented an advanced stage and metastatic disease in one case. The treatment was a total nephrectomy with ganglioma dissection when the tumor was resectable followed by chemotherapy and radiotherapy. Two patients was in progressive disease despite treatment, and one patient was lost at follow-up. The prognosis of adult's nephroblastoma remains very severe, due to the advanced stage at diagnosis and the mediocre reply to the treatment.

Abstract
We describe an unusual case of primary synovial sarcoma of the kidney. A 47-year-old woman had a tumor massively replacing the right kidney. There were no primary extrarenal neoplastic lesions. Microscopically, the tumor was composed of a cellular proliferation of relatively uniform spindle-shaped cells having atypical spindle or oval nuclei arranged in fascicles with tumor necrosis, without epithelial areas. Immunohistochemically, a small number of the tumor cells were positive for epithelial markers such as cytokeratin and epithelial membrane antigen. The SYT-SSX2 fusion transcripts were detected by a reverse transcription-polymerase chain reaction (RT-PCR) using RNA extracted from formalin-fixed, paraffin-embedded tissue. ETV6-NTRK3 fusion gene transcripts that result from t(12; 15)(p13;q25), which is characteristic of cellular congenital mesoblastic nephroma, were not demonstrated. To our knowledge, this is the ninth case of primary renal synovial sarcoma. This case report indicates that synovial sarcoma should be taken into account for the differential diagnosis of renal spindle cell tumors and the molecular assay detecting the SYT-SSX fusion transcripts is useful for the final diagnosis of synovial sarcoma arising in an unusual location.

Abstract
Nephroblastoma (Wilms' tumour) is very rarely found in adult patients. We report on 10 cases to demonstrate the diagnostic and therapeutic problems. In case of flank pain, large tumour mass, fast tumour growth and young age, the possibility of Wilms' tumour should be taken into consideration even in adult patients. The chances for a successful treatment by primary surgery with adjuvant therapy are favourable for the lower stages I and II. All our patients presenting with tumour stages I and II have survived and have been free of disease for 68 months now. One of the patients with stage III Wilms' tumour died 8 months postoperatively while the other one has been free of disease for 120 months now. In the advanced stage IV no patient survived. In cases of inoperable large tumours in adults, the possibility of primary chemotherapy should be considered under certain circumstances. Rapid tumour regression may confirm the diagnosis and will make feasible a salvage operation in some cases.

Abstract
Wilms' tumor is rare in adults. Its histology, grading and staging are identical to those in children. Investigators agree on a combined modality approach in the treatment of adult Wilms' tumor (AWT), but differ on how aggressive it should be. Some advocate adopting the current pediatric protocols which take into account tumor stage and grade. Others recommend using advanced disease regimens for all stages and grades. We report on an 18 year-old male with stage IV favorable histology Wilms' tumor. The patient underwent radical nephrectomy and received postoperative radiotherapy with intensive four-drug chemotherapy. He had one relapse after 12 months which was successfully treated with chemotherapy and radiotherapy. He remains in remission without relapses 36 months after the initial diagnosis. The genetics of Wilms' tumor has been well studied in children but is practically unknown in adults; karyotype and molecular genetic studies in this case were normal.

Abstract
Wilms' tumor is a rare malignancy of kidney in adults. It usually cannot be differentiated from other renal masses preoperatively. This is a presentation of a case of adult Wilms' tumor who developed spontaneous hemorrhage during radiological evaluation. As tumor rupture can change the stage of the tumor and alter the prognosis of the patient, urgent work-up and treatment is advised.

Abstract
BACKGROUND Wilms' tumor in an adult is rare and no treatment guidelines have been established, although all authors recommend aggressive therapy based on surgery, radiotherapy, and multiagent chemotherapy. METHODS The authors describe a case of Wilms' tumor in a 23-year-old woman who developed hepatic and pulmonary metastases after undergoing nephrectomy. Treatment was initiated with carboplatin, etoposide, ifosfamide, and epirubicin combination chemotherapy and irradiation of the tumor bed, lungs, and liver. RESULTS Metastatic workup was negative 41 months after suspension of chemoradiotherapy. Hematologic toxicity was high, but was manageable with adequate supportive care. CONCLUSIONS Because this multimodal treatment, which included a chemotherapeutic regimen with single agents generally used in patients with recurrent disease, had impressive activity in this patient with an advanced adult Wilms' tumor, the issue of further investigation of this alternative schedule is raised.

Abstract
Nephroblastoma (Wilms’ tumour) is very rarely found in adult patients. We report on 10 cases to demonstrate the diagnostic and therapeutic problems. In the case of flank pain, large tumour mass, fast tumour growth and young age, the possibility of Wilms’ tumour should be taken into consideration even in adult patients. The chances for successful treatment by primary surgery with adjuvant therapy are favourable for the lower stages I and II. All our patients presenting with tumour stages I and II have survived and have been disease free for 68 months now. One of the patients with Wilms’ tumour stage III died 8 months postoperatively while another one has been disease-free for 120 months now. In the advanced stage IV, no patient survived. In cases of inoperable large tumours in adults, the possibility of primary chemotherapy should be considered under certain circumstances. Rapid tumour regression may confirm diagnosis and will enable salvage operation in some cases.

Abstract
Wilms' tumor is the most common malignant tumor of the urinary tract in children but is rare in adults. Although histologically the tumors appear to be the same, successful treatment with multimodal therapy is much more common in childhood. We report on 2 patients with adult, anaplastic, Stage IV Wilms' tumor, one of which was discovered during pregnancy and was managed successfully with chemotherapy, including ifosfamide, carboplatinum, and etoposide. As more patients are properly identified and treatment outcomes with chemotherapeutic regimens documented, better therapeutic approaches in adult Wilm's tumor will be developed, resulting in improved survival.

Abstract
BACKGROUND Wilms' tumor is rare in adults. The recommended treatments for patients with Stage II adult Wilms' tumor with favorable histology (FH) nephroblastomas are conflicting. METHODS Two patients with Stage II, favorable histology, adult nephroblastomas are described. Current treatment modalities are discussed and the literature is reviewed. RESULTS The first patient, a 52-year-old woman, probably had a late local relapse of a Wilms' tumor 21 years after nephrectomy because of a renal tumor originally diagnosed as reticular sarcoma. In this case, a recurring or an extrarenal Wilms' tumor should have been considered. After the tumor was removed, the patient received adjuvant chemotherapy with dactinomycin and vincristine and was disease free 44 months after diagnosis. The Wilms' tumor in the second patient, a 33-year-old woman, was discovered accidentally and classified as Stage II/FH based on preoperative biopsy. She was treated with radical nephrectomy and adjuvant chemotherapy with dactinomycin and vincristine. This patient was disease free 24 months after surgery. CONCLUSIONS Surgery and two-drug chemotherapy with dactinomycin and vincristine is suggested for patients with Stage II adult Wilms' tumor with FH nephroblastomas.

Abstract
The Institut Gustave Roussy experience with nephroblastoma in 22 patients older than 16 years during a 19-year period (1973-1992) was retrospectively reviewed. All patients underwent a nephrectomy. There were 4 stage I, 8 stage II, 3 stage III and 7 stage IV patients. Initial postnephrectomy therapy included single modality approach in 7 patients (radiotherapy in 1 and chemotherapy in 6) and combined modality approach (radiotherapy and chemotherapy) in 15 patients. The agents used most often were actinomycin, vincristine and doxorubicin. 2 of 7 (29%) and 7/15 (47%) patients are disease-free survivors after first-line treatment. Salvage chemotherapy was given in 13 patients. Only 1 patient experienced a subsequent sustained complete remission. After a mean follow-up of 100 months (range 10-240), 12/22 patients (55%) are alive, including 10 who are disease-free (45%). We confirm that adult patients are likely to have more advanced disease and poorer prognosis than children. The combined modality approach is more active than one-modality therapy. Aggressive treatment, including the three-drug regimen actinomycin+vincristine+doxorubicin, regardless of stage, associated to irradiation starting from stage II, is recommended.

Abstract
Wilms' tumour, or nephroblastoma, is the commonest renal neoplasm found in children, but is rarely found in adults, the world literature recording only approximately 200 cases. Individual case reports continue to be published but only within the last 10 years have definitive treatment regimes been suggested. In order to determine the UK experience of adult Wilms' tumour, members of the British Association of Urological Surgeons were circulated with a questionnaire, and from 141 replies, 13 members reported 17 cases. Critical review of the original histology slides excluded 3 of these; the 14 remaining cases are described and their management discussed in the light of current recommended treatment.
