BACKGROUND: Incidental findings on neuroimaging in the pediatric population are an emerging treatment challenge. Treatment options for these incidental childhood brain mass lesions, which radiologically may be assumed to be low-grade gliomas (LGG), vary, ranging from careful conservative "wait and scan" treatment to surgical biopsy, gross total resection, and upfront radiation and/or chemotherapy. As malignant transformation of LGG in children is extremely rare, some series advocate careful conservative management of these lesions; however, universal treatment protocols are not totally agreed upon...

Over the last 50 years, collaborative clinical trials have reduced the number of children dying from pediatric cancer significantly. Unfortunately, certain tumor types have remained resistant to conventional surgical, radiotherapy and chemotherapy combinations, and relapsing and/or refractory disease remains associated with dismal outcomes. Recently, renewed attention has been given to the role for immunotherapies in pediatric oncology. In fact, these combine several attractive features, including (but possibly not limited to) the specificity for cancer cells, potentially in vivo persistence and longevity, and potency against refractory disease...

IMPORTANCE: Mammary Analogue Secretory Carcinoma (MASC) is a newly characterized salivary gland carcinoma resembling secretory carcinoma of the breast. Prior to being described, MASC was most commonly misdiagnosed as Acinic Cell Carcinoma. Though MASC is predominantly an adult neoplasm, cases have been reported in the pediatric population. Reporting and summarizing of known cases is imperative to understand the prognosis and clinical behavior of MASC. OBJECTIVE: EVIDENCE REVIEW: Web of Science, Medline, EMBASE, and The Cochrane Library were searched for studies that included pediatric cases of MASC...

BACKGROUND: Dysembryoplastic neuroepithelial tumors (DNETs) are rare, benign brain neoplasms that typically arise in children and adolescents and classically present with intractable, partial complex seizures. DNETs are classically associated with a favorable prognosis after complete surgical resection. CASE DESCRIPTION: We describe a case of long-term recurrence of a DNET, which initially resected and diagnosed as an oligodendroglioma prior to the recognition of DNETs...

The more common causes of parotid enlargement in children are infections and inflammatory conditions. Primary neoplasms of the parotid glands are rare in pediatric age group; however, secondary malignancies have been reported in survivors of childhood leukemia. The parotid glands have been the sites of relapses in acute lymphoblastic leukemia (ALL) and acute myeloid leukemia. However, bilateral parotid involvement as an initial presentation of ALL is rarely reported. We present a case of an 8-year-old boy who presented with bilateral parotid enlargement as an initial manifestation of ALL...

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by excessive activation of the immune system, resulting in overproduction of inflammatory cytokines. Patients usually present with high fever, cytopenias, hyperferritinemia, and hepatosplenomegaly, and their disease process ranges from mild to fatal multiorgan failure. HLH is a heterogeneous group of disorders that can be triggered by infections, neoplasms, or autoimmune diseases. The HLH diagnosis can be difficult to confidently confirm in critically ill patients while waiting for pathology or reference laboratory results to return, delaying the diagnosis with significantly worsened outcomes...

BACKGROUND: Many epidemiological studies have examined associations between birth defects (BDs) and pediatric malignancy over the past several decades. Our objective was to conduct a systematic literature review of studies reporting on this association. METHODS: We used librarian-designed searches of the PubMed Medline and Embase databases to identify primary research articles on pediatric neoplasms and BDs. English language articles from PubMed and Embase up to 10/12/2015, and in PubMed up to 5/12/2017 following an updated search, were eligible for inclusion if they reported primary epidemiological research results on associations between BDs and pediatric malignancies...

Langerhans cell histiocytosis (LCH) is an inflammatory myeloid neoplasm characterized by constitutive activation of extracellular signal-regulated kinase (ERK). Genomic characterization has identified activating point mutations including mutually exclusive BRAFV600E and activating MAP2K1 mutations to be responsible for ERK activation in a majority of pediatric LCH patients. Here, we report the discovery of a novel BRAF kinase fusion, PACSIN2-BRAF, in a child with multisystem LCH. This is the second reported case of an activating BRAF kinase fusion and indicates a recurrent pathologic mechanism...

Noonan syndrome (NS) is associated with short stature. Growth hormone treatment has been FDA approved for use in these patients. Children with NS are at a higher risk of developing benign and malignant proliferative disorders, primary brain tumors being one of them. Since growth hormone therapy can worsen the tumor burden, screening with a brain MRI prior to growth hormone initiation in NS patients is strongly recommended. Here we present two NS patients who developed different primary brain tumors while being on growth hormone therapy...

Salivary gland epithelial neoplasms are rare in children and adolescents with only a handful of large series have been published. A retrospective study was conducted for 57 cases in patients 20years or younger. The tumors were located in the parotid (n=36), submandibular gland (n=7), and minor salivary glands (n=14). 19 (33%) tumors were pleomorphic adenoma, while the remaining (67%) were malignant. The histologic types of carcinomas were mucoepidermoid carcinoma (MEC, n=19, 33%), acinic cell carcinoma (n=7, 12%), adenoid cystic carcinoma (n=6, 11%), secretory carcinoma (mammary analogue) (SC, n=4, 7%), and myoepithelial carcinoma (n=2, 4%)...

Adenoid cystic carcinoma (ACC) of the lacrimal gland is an aggressive, malignant epithelial neoplasm. This tumor is rarely seen in adults and even less commonly seen in children and adolescents; thus, there have been no large studies to date describing the optimal treatment of this malignancy in the pediatric population. Here, we report a case of lacrimal gland ACC in a 14-year-old male treated with neoadjuvant intra-arterial chemotherapy followed by globe-sparing tumor resection and chemoradiation. At 2-year follow-up, he remains disease free without evidence of tumor recurrence...

Osteochondromas, the most common benign bone tumors, are cartilaginous neoplasms of unknown origin with rare malignant potential. Osteochondromas rarely occur in the head and neck, and diagnosis relies on a combination of clinical, radiological, and histological criteria. Excision is often curative. We describe the first reported case of hyoid osteochondroma in an adolescent male with multiple osteochondroma, discuss its surgical management, and perform a review of the salient literature. Osteochondroma represents a rare diagnosis to include in the differential of any midline neck mass...

Extragonadal teratoma originating from the retroperitoneum represents less than 5% of all teratomas and accounts for less than 10% of all pediatric retroperitoneal neoplasms. To date, there has been no report of teratoma managed with LT. This study reports an infant aged 3 months with retroperitoneal immature teratoma involving the hepatic hilum, refractory to chemotherapy and treated with LT. The patient was referred to our hospital for management of a growing abdominal mass. Histopathology of a fine needle biopsy of the lesion suggested the possibility of a hepatoblastoma with teratoid features...

BACKGROUND: Pilocytic astrocytoma (PA) is the most prevalent central nervous system (CNS) tumor in pediatric population and accounts for an approximate of 5-6% of all gliomas. This neoplasm can occur at all levels of the neuraxis, with majority (67%) arising in the cerebellum and optic pathway. PAs are World Health Organization Grade I tumors and are the most benign of all astrocytomas characterized by an excellent prognosis. Other differentials include subependymal giant cell astrocytoma (SEGA), ependymoma, meningioma, and low-grade gliomas such as pilocytic or diffuse astrocytoma; calcification is more commonly regarded as a feature of benign or slow-growing tumors...

We report a case of a recurrent clear cell meningioma (ccm) in the frontal lobe of the brain of a 67-year-old man. The patient developed three recurrences: at 3, 10, and 12 years after his initial surgery. Histopathology observations revealed a grade 2 ccm with positivity for vimentin and epithelial membrane antigen. Expression of E-cadherin was positive only in the primary tumour and in the first available recurrence. Fluorescence in situ hybridization analyses demonstrated 1p and 14q deletions within the last recurrence...

Myoepithelial neoplasms of soft tissue represent a heterogeneous group of lesions, encompassing both benign entities as myoepithelioma (ME) and highly aggressive tumors as myoepithelial carcinoma (MEC). We describe a case of pediatric soft tissue MEC with peculiar features that may lead to misdiagnosis: congenital onset and presence of a benign component with predominant cystic structure. Few cases of congenital MEC have been reported, but the coexistence of MEC with ME is even more rare, accounting for less than 1% of myoepithelial tumors...

Hereditary gastrointestinal cancer predisposition syndromes have been well characterized, but management strategies and surveillance remain a major challenge, especially in childhood. In October 2016, the American Association for Cancer Research organized the AACR Childhood Cancer Predisposition Workshop in which international experts in care of children with a hereditary risk of cancer met to define surveillance strategies and management of children with cancer predisposition syndromes. In this article, we review the current literature in polyposis syndromes that can be diagnosed in childhood and may be associated with an increased incidence of gastrointestinal neoplasms and other cancer types...

PURPOSE OF REVIEW: Denosumab is an inhibitor of receptor activator of nuclear factor kappa-B ligand (RANKL), and has emerged as an important novel therapy for skeletal disorders. This article examines the use of denosumab in children. RECENT FINDINGS: Considerable safety and efficacy data exists for denosumab treatment of adults with osteoporosis, bone metastases, and giant cell tumors. Pediatric data is limited; however, evidence suggests denosumab may be beneficial in decreasing bone turnover, increasing bone density, and preventing growth of certain skeletal neoplasms in children...
