BACKGROUND: Malignant peripheral nerve sheath tumors (MPNSTs) are rare tumors, generally high-grade, and comprise ~ 5-10% of soft tissue sarcomas. Over two-thirds of MPNSTs metastasize, and upwards of 40% clinically recur. Etiologic risk factors for MPNSTs are historically understudied. There is evidence to suggest MPNST incidence differs across racial/ethnic groups in pediatric populations. Therefore, we sought to estimate differences in MPNST incidence by race/ethnicity among all ages in the United States...

Background: Imaging studies, particularly simple and contrast-enhanced tomography, constitute the first diagnostic approach to detect recurrence of musculoskeletal tumors. The aim of the present retrospective study was to demonstrate the usefulness of scintigraphy plus SPECT/CT (single photon emission computed tomography) with thallium-201 (201 Tl) in the evaluation of malignant musculoskeletal tumors with suspicion of recurrence or metastatic disease. Methods: Eight weeks after the last therapy, 72 scintigraphy and SPECT/CT studies were performed to assess regional recurrence and metastatic disease in 42 patients with different types of malignant musculoskeletal tumors, such as osteosarcoma, Ewing's sarcoma, rhabdomyosarcoma, retinoblastoma, synovial sarcoma, and Wilms tumor at the Hospital Infantil de México Federico Gómez...

BACKGROUND Acute promyelocytic leukemia (APL) is a very rare leukemia in children. Extramedullary involvement by APL has been reported in between 3-5% of cases, mainly associated with cases of relapse. A rare case of relapse of APL in a 9-year-old child is presented with skin involvement with myeloid sarcoma. CASE REPORT A 9-year-old male child was admitted to the Oncology Service of the hospital complaining of fever, progressive fatigue, oral petechiae with severe bleeding in the oral cavity. Bone marrow examination showed some promyelocytes...

Pelvic Ewing sarcoma is associated with a worse prognosis. Thromboembolic events are relatively common in pediatric patients with cancers including sarcomas. We have presented a case of Ewing sarcoma arising from the left iliac bone with tumor thrombus of inferior vena cava (IVC) which was obtained complete response by both chemotherapy and irradiation. Magnetic resonance imaging (MRI) scan demonstrated that the tumor arising from the left iliac bone extended into the left side of sacral bone, suggesting the difficulty of surgical resection...

Clear cell sarcoma of the kidney (CCSK) is an uncommon renal neoplasm of childhood. It represents between 2% and 9% of all pediatric renal tumors, and generally arises before the age of 5 years. It often mimics other pediatric renal tumors. Presently described is the case of a 7-year-old girl who presented with complaints of vomiting and abdominal pain. Abdominal ultrasonography revealed a right renal mass, and the patient developed a renal hematoma a few hours after admission. The patient underwent a nephroureterectomy with a provisional diagnosis of Wilms tumor; however, histopathological examination of a specimen revealed CCSK...

BACKGROUND: Pediatric head and neck malignancies are rare and only a few descriptive epidemiological studies have been published. Using unique nationwide registries, we report age-specific incidence rates of head and neck cancer (HNC) among children during four decades. METHODS: Data were obtained from the Danish Cancer Registry. We included children aged 0-14 years diagnosed between January 1, 1978 and December 31, 2014 with extra-orbital, nonskin and nonbone HNC...

Ewing's sarcoma (ES) is the second-most frequent pediatric bone tumor. Chromosomal translocation t(11;22)(q24:q12) results in the formation of EWS/FLI1 gene fusion, which is detected in approximately 90% of tumors of the Ewing family. Several transcriptome studies have provided lists of genes associated with EWS/FLI1 expression. However, the protein expression profiles associated with EWS/FLI1 have yet to be elucidated. In this study, to identify the regulated proteins associated with EWS/FLI1 and therapeutic targets in ES, we conducted proteomic studies using EWS/FLI1 knockdown in four Ewing's sarcoma cell lines and human mesenchymal stem cells (hMSCs) expressing EWS/FLI1...

Desmoplastic small round cell tumor (DSRCT) is a rare sarcoma that typically affects pediatric and young adult patients with a median age in the general and in the pediatric population of 24.6 years (range 4-58 years) and 15.0 years (range 0-21 years) respectively, with a strong male predominance. This tumor is characterized by a specific t(11;22)(p13;q12) that results in fusion of EWS and WT1 genes which can be demonstrated by RT-PCR or by FISH. DSRCT most frequently presents as an intra-abdominal primary mass associated with peritoneal seeding and a highly aggressive pattern of spread...

Angiosarcoma is a malignant vascular tumor derived from the mesenchymal cells which have undergone an angioblastic differentiation. About half of the angiosarcomas are reported to localize in the skin and soft tissues of the head and neck, i.e., found predominantly to arise from the scalp and face. Angiosarcomas rarely involve the skeletal system, wherein they generally have a tendency for multicentricity. Primary bony angiosarcoma accounts for about 6% of all the angiosarcomas and about 1.4% of all the primary bony sarcomas...

Synovial sarcoma is the uncommon malignant tumor of children and adolescents. It usually involves the soft tissues of the upper and lower joints and most commonly affects adults in their fourth decade of life. We report a rare case of synovial sarcoma of the head and neck region in a five-year-old child who has presented with right side cervical lymphadenopathy associated with dysphagia and hoarseness of voice. Patient was managed by modified radical neck dissection followed by chemotherapy.

PURPOSE OF REVIEW: Our purpose is to discuss the importance of multimodality imaging in the assessment of cardiac tumors and management. We have compiled a recent review of the scientific literature and embedded our clinical pathways and recommendations based on data and clinical experience. RECENT FINDINGS: The use of contrast echocardiography in the assessment of cardiac masses has been shown to be helpful in distinguishing tumor from thrombus. Deformation imaging of cardiac tumors has been shown to differentiate better rhabdomyomas from fibromas in pediatric patients...

Children with high risk sarcoma have a poor prognosis despite surgical resection, irradiation and chemotherapy. Alternative therapies are urgently needed. Urokinase-type plasminogen activator receptor (uPAR) and epidermal growth factor receptor (EGFR) are surface proteins expressed by some pediatric sarcomas. We show for the first time that a de-immunized bispecific ligand toxin, EGFATFKDEL, directed against EGFR and uPAR, successfully targets pediatric sarcoma. Using flow cytometry, we identified a rhabdomyosarcoma (RMS) cell line, RH30, that expresses both uPAR and EGFR, and a Ewing sarcoma (EWS) cell line, TC-71, that expresses only uPAR...

Pediatric cancer is the second cause of death in children older than 5 years in our country, after trauma. Positron emission tomography/computed tomography (PET/CT) is a hybrid technique that involves radiation, which has been used for some time in adults and is being progressively imple mented in children. This technique allows morphological and functional assessments of the body with applications in neoplastic and non-neoplastic pathology. Its main role in oncology is in the evaluation and control of lymphomas, sarcomas and neuroblastomas, among others...

INTRODUCTION: Neck pain and torticollis are common symptoms in the pediatric population that rarely requires further investigation. However, in case symptoms persist, then a more meticulously approach should be considered. Underlying conditions such as infections, neck injury, autoimmune disorders or even cervical spine cancer should be excluded from diagnosis. Cervical spine cancer is a rare neurosurgical entity in the pediatric population and even rarer is atlantoaxial Ewing's sarcoma...

Osteogenic sarcoma (OS) is the most common malignant bone tumor in children and adolescents. Despite advances in molecular genetic characterization of pediatric and adult tumors, the diagnosis of OS still depends almost entirely on light microscopy. The lack of consistent genetic changes in OS has greatly hindered the development of any diagnostic molecular test. Recently, whole-genome sequencing has shown that ~50% of cases of OS have a translocation involving the TP53 gene with breakpoints confined to the first intron...

Owing to its rarity, rhabdomyosarcoma of the head and neck (HNRMS) has seldom been discussed in the literature. As most of the data is based only on the retrospective experiences of tertiary healthcare centers, there are difficulties in formulating a standard treatment protocol. Moreover, the disease is poorly understood at its pathological, genetic, and molecular levels. For instance, 20% of all histological assessment is inaccurate; even an experienced pathologist can confuse rhabdomyosarcoma (RMS) with neuroblastoma, Ewing's sarcoma, and lymphoma...

BACKGROUND: Anti-TNF (Tumor necrosis factor) therapy is effective in treating pediatric patients with refractory rheumatic disease. There is however a concern that anti-TNF usage may increase the risk of malignancy. Reports on specific types of malignancy in this patient population have been emerging over the past decade, but there is a need for additional malignancy reports, as these events are rare. Therefore, a retrospective chart review was performed on the biologic database of pediatric rheumatology patients at The Hospital for Sick Children (SickKids) from 1997 to 2013 for neoplasms, patient demographic information and rheumatologic treatment course...
