Abstract
Pediatric renal sarcomas are exceedingly rare entities that present diagnostic challenges. We report a remarkable case of a 14-month-old female with an 8 cm right renal mass, accompanied by disseminated bone metastases, posing intricate clinical and histopathological dilemmas. Initial suspicion leaned towards clear cell sarcoma of the kidney (CCSK), however, subsequent histological examination post-chemotherapy revealed high-grade osteosarcoma and further differential considerations arose, including primary renal osteosarcoma and osseous osteosarcoma with secondary renal involvement. Despite inconclusive histology, treatment proceeded with the UH1 chemotherapy protocol for CCSK, incorporating high-dose Methotrexate for potential osteosarcoma, and the patient demonstrated a favorable response to therapy.

Abstract
Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric and adolescent population, with 350 new cases diagnosed each year. While they can develop anywhere in the body, the genitourinary tract is the second most common primary location for an RMS to develop. Overall survival has improved through the increased use of protocols and multidisciplinary approaches. However, the guidelines for management continue to change as systemic and radiation therapeutics advance. Given the relative rarity of this disease compared to other non-solid childhood malignancies, healthcare providers not directly managing RMS may not be familiar with their presentation and updated management. This review aims to provide foundational knowledge of the management of RMSs with an emphasis on specific management paradigms for those arising from the genitourinary tract. The genitourinary tract is the second most common location for an RMS to develop but varies greatly in symptomology and survival depending on the organ of origin. As the clinical understanding of these tumors advances, treatment paradigms have evolved. Herein, we describe the breadth of presentations for genitourinary RMSs with diagnostic and treatment management considerations, incorporating the most recently available guidelines and societal consensus recommendations.

Abstract
DICER1 syndrome (OMIM 606241, 601200) is a rare autosomal dominant familial tumor predisposition disorder with a heterozygous DICER1 germline mutation. The most common tumor seen clinically is the pleuropulmonary blastoma (PPB), a lung neoplasm of early childhood which is classified on its morphologic features into four types (IR, I, II and III) with tumor progression over time within the first 4-5 years of life from the prognostically favorable cystic type I to the unfavorable solid type III. Following the initial report of PPB, its association with other cystic neoplasms was demonstrated in family studies. The detection of the germline mutation in DICER1 provided the opportunity to identify and continue to recognize a number seemingly unrelated extrapulmonary neoplasms: Sertoli-Leydig cell tumor, gynandroblastoma, embryonal rhabdomyosarcomas of the cervix and other sites, multinodular goiter, differentiated and poorly differentiated thyroid carcinoma, cervical-thyroid teratoma, cystic nephroma-anaplastic sarcoma of kidney, nasal chondromesenchymal hamartoma, intestinal juvenile-like hamartomatous polyp, ciliary body medulloepithelioma, pituitary blastoma, pineoblastoma, primary central nervous system sarcoma, embryonal tumor with multilayered rosettes-like cerebellar tumor, PPB-like peritoneal sarcoma, DICER1-associated presacral malignant teratoid neoplasm and other non-neoplastic associations. Each of these neoplasms is characterized by a second somatic mutation in DICER1. In this review, we have summarized the salient clinicopathologic aspects of these tumors whose histopathologic features have several overlapping morphologic attributes particularly the primitive mesenchyme often with rhabdomyoblastic and chondroid differentiation and an uncommitted spindle cell pattern. Several of these tumors have an initial cystic stage from which there is progression to a high grade, complex patterned neoplasm. These pathologic findings in the appropriate clinical setting should serve to alert the pathologist to the possibility of a DICER1-associated neoplasm and initiate appropriate testing on the neoplasm and to alert the clinician about the concern for a DICER1 mutation.

Abstract
Although the second peak of the age distribution of rhabdomyosarcoma (RMS) is at adolescence, renal RMS is extremely rare at this age group. This tumor is indistinguishable from other renal tumors based on clinical and imaging findings, and the diagnosis relies on histology and immunohistochemical staining. We report a unique case of adolescent renal RMS associated with tumor thrombus extending into the inferior vena cava (IVC) and right atrium.An 18-year-old female adolescent presented with shortness of breath and palpitations, associated with right flank discomfort, and hematuria. A pleomorphic-type renal RMS with Budd-Chiari syndrome and arrhythmia induced by IVC and RA thrombosis was diagnosed. Despite complete tumor resection, the patient developed multiple lung metastases a month after surgery. Chemotherapy was recommended, but the patient declined. She died within a year of the initial operation.Adolescent renal RMS is rare and associated with poor outcome. Early aggressive multimodal therapy seems to be appropriate, in particular, in the presence of tumor thrombosis.

Abstract
Rhabdomyosarcoma (RMS) is one of the common malignant tumors in the pediatric age group. There is only a single case report of primary renal alveolar RMS. Fine needle aspiration (FNA) findings of primary renal RMS has not been reported so far. Hence we present an unusual case of primary alveolar RMS of the kidney. An 11 year old boy presented with an abdominal mass. On FNA a diagnosis of undifferentiated sarcoma and anaplastic Wilms tumor were considered. The tumor was resected and showed histopathological features of alveolar rhabdomyosarcoma. He developed multiple bony metastases and succumbed to the illness despite aggressive chemotherapy. RMS of the kidney should be considered in the differential diagnosis of children with a renal mass, and may have an aggressive clinical course with bone metastases.

Abstract
The pathogenesis of cystic nephroma of the kidney has interested pathologists for over 50 years. Emerging from its initial designation as a type of unilateral multilocular cyst, cystic nephroma has been considered as either a developmental abnormality or a neoplasm or both. Many have viewed cystic nephroma as the benign end of the pathologic spectrum with cystic partially differentiated nephroblastoma and Wilms tumor, whereas others have considered it a mixed epithelial and stromal tumor. We hypothesize that cystic nephroma, like the pleuropulmonary blastoma in the lung, represents a spectrum of abnormal renal organogenesis with risk for malignant transformation. Here we studied DICER1 mutations in a cohort of 20 cystic nephromas and 6 cystic partially differentiated nephroblastomas, selected independently of a familial association with pleuropulmonary blastoma and describe four cases of sarcoma arising in cystic nephroma, which have a similarity to the solid areas of type II or III pleuropulmonary blastoma. The genetic analyses presented here confirm that DICER1 mutations are the major genetic event in the development of cystic nephroma. Further, cystic nephroma and pleuropulmonary blastoma have similar DICER1 loss of function and 'hotspot' missense mutation rates, which involve specific amino acids in the RNase IIIb domain. We propose an alternative pathway with the genetic pathogenesis of cystic nephroma and DICER1-renal sarcoma paralleling that of type I to type II/III malignant progression of pleuropulmonary blastoma.

Abstract
Intra-abdominal desmoplastic small round cell tumor (DSRCT) is a rare, aggressive tumor affecting adolescent and young males. DSRCT presenting as a primary renal mass in the absence of visceral or serosal involvement is extremely rare. Herein, we present the pathologic and molecular findings in the case of a young man who presented with a large renal mass without any visceral or serosal involvement. Noticeably, the tumor lacked prominent desmoplastic stroma and only focally expressed cytokeratin, both of which are considered characteristic histologic features for this tumor. Fluorescence in situ hybridization studies using an EWSR1 break-apart probe confirmed the presence of a rearrangement involving the EWSR1 locus and RT-PCR demonstrated the presence of an EWSR1-WT1 fusion transcript associated with the t(11;22) rearrangement, which supported a diagnosis of DSRCT. We also discuss the differential diagnostic considerations faced by the pathologist in the workup of small round cell neoplasms of the kidney.

Abstract
BACKGROUND Rhabdomyosarcoma (RMS) is one of the common malignant tumors in infants and children, but it is extremely rare in the kidney. In this paper, we present a case of RMS the kidney of a child. CASE PRESENTATION A 6-month old girl presented with agitation, low fever and abdominal distention which started 5 days ago. On physical examination, the infant had a large and firm soft tissue mass in the palpation of her abdomen. Plain abdominal x-ray, sonography and CT scan showed soft tissue mass and Doppler ultrasound demonstrated regions of vascular flow in mass. The abdominal mass was replaced and on pathological examination and immunohistochemistry the diagnosis was embryonal RMS. CONCLUSION Rhabdomyosarcoma of the kidney should be considered in the differential diagnosis of children with huge abdominal mass.

Abstract
INTRODUCTION Rhabdomyosarcomas (RMS) are rare heterogeneous pediatric tumors that are treated by surgery, chemotherapy and irradiation. New therapeutic approaches are needed, especially in the advanced stages to target the pro-oncogenic signals. Exploring the molecular interactions of the regulatory signals and their roles in the developmental aspects of different subtypes of RMS is essential to identify potential targets and develop new therapeutic drugs. AREAS COVERED Insights into different drug discovery approaches are discussed with specific emphasis on gene expression profiling, fusion protein, role of small interfering RNA (siRNA)- and microRNA (miRNA)-based discovery approaches, targeting cancer stem cells, and in vitro and in vivo model systems. Targeting some overexpressed signals along with the possibilities of combination therapy of validated drug targets is discussed. Additionally, methods to overcome the limitations of discovery-based research are briefly discussed. EXPERT OPINION Due to drug resistance, ineffective therapy in advanced stages and relapse, there is a demand to explore new drug targets and discovery approaches. Implementing miRNA-based profiling would reveal the extent of miR-based regulation, various biomarkers and potential targets in RMS. A suitable combination of innovative techniques and the use of model systems might assist the identification and validation of novel targets and drug discovery methods. Combining specific drugs along with type-specific target inhibition of overexpressed mRNAs through siRNA approaches would enable the development of personalized therapy.

Abstract
PURPOSE OF REVIEW We will review the 2007/2008 literature on pediatric genitourinary tumors. RECENT FINDINGS Newly identified constitutional epigenetic defects in Wilms tumor genes extend the understanding of Wilms tumor risk in children lacking syndromic features, and add to the complexity of the pathogenesis of these tumor suppressor genes. Pediatric renal cell carcinoma has distinct molecular characteristics and clinical associations from the adult counterpart. The pathway from PAX3-FKHR translocation to the development of rhabdomyosarcoma tumors has been further elucidated. SUMMARY Therapeutic strategies continue to be driven by developments in molecular diagnostics in pediatric genitourinary tumors.
