OBJECTIVE: Solitary mass lesions of the palatine tonsils are rare in children. While a tonsillar mass can be concerning for a neoplasm, benign conditions may present with a mass arising from the surface of the palatine tonsils in children. We describe clinical and histopathological characteristics of a lymphoid polyp in a child with unilateral tonsillar mass. METHODS: Retrospective chart review. RESULTS: A 6-year-old girl presented for evaluation of recurrent acute tonsillitis and a mass on the left palatine tonsil...

BACKGROUND: DICER1 syndrome is a pediatric cancer predisposition condition causing a variety of tumor types in children and young adults. In this report we studied a family with two relatives presenting a variety of neoplastic conditions at childhood. METHODS: Germ-line mutation screening of the complete coding region of the DICER1 gene in genomic DNA from the proband was performed. The presence of somatic DICER1 mutation and further alterations in driver genes was investigated in genomic DNA obtained from available tumor samples...

BACKGROUND: Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child. CASE PRESENTATION: An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1...

Medulloblastoma is a common tumor of the posterior fossa, representing 20-25% of all pediatric neoplasms. It commonly occurs in the midline (cerebellar vermis) and rarely at the cerebellopontine angle. Most of them are intra-axial, and an extra-axial location of this tumor is very rare. Extra-axial cerebellopontine angle medulloblastoma is extremely uncommon and has never been reported in an infant. We report an extra-axial cerebellopontine angle medulloblastoma in a 1-year-old child.

The ribs are frequently affected by blunt or penetrating injury to the thorax. In the emergency department setting, it is vital for the interpreting radiologist to not only identify the presence of rib injuries but also alert the clinician about organ-specific injury, specific traumatic patterns, and acute rib trauma complications that require emergent attention. Rib injuries can be separated into specific morphologic fracture patterns that include stress, buckle, nondisplaced, displaced, segmental, and pathologic fractures...

PURPOSE: Giant pediatric intracranial tumor (GPIT) remains to be a challenging disease with high morbidity and mortality. METHODS: The clinical data of 60 patients under 18 years of age operated on with GPIT (≥5 cm in diameter) were retrospectively analyzed. RESULTS: Gross total resection was achieved in 46 cases (77%) and subtotal resection was obtained in 14 cases (23%). Ninety percent (47/52) of the cases with obstructive hydrocephalus were resolved remarkably and only 10% (5/52) of the patients needed a ventriculoperitoneal shunt after tumor resection...

The term cystic nephroma has traditionally been used to refer to 2 neoplasms, a lesion in adults that is now thought to be part of the spectrum of mixed epithelial stromal tumor (MEST) and a pediatric lesion that has been associated with mutations in the DICER1 gene. A direct detailed morphologic, immunohistochemical, and genetic comparison of these 2 lesions has not been performed. In this study, we compare the morphologic features, immunoreactivity for estrogen receptor and inhibin, and DICER1 genetic status of 12 adult cystic nephroma/MEST (median age 50...

Central nervous system (CNS) tumors represent the second most prevalent group of cancers in children and adolescents, yet account for the majority of childhood cancer-related deaths and considerable morbidity among survivors, due to high-intensity non-selective standard therapies delivered to immature nervous system structures undergoing development. These tumors arise at different ages -not infrequently very early in life-, in different locations and cellular contexts, have varied cell types of origin, and have heterogeneous responses to the "classic" current therapeutic approaches...

Only nine cases of bronchial granular cell tumor have previously been reported in pediatric patients. We present a 15-year-old girl with acute-onset right shoulder pain, discovered to have a granular cell tumor causing bronchial stenosis and a cavitating post-obstructive right upper lobe pneumonia. The patient was treated with lobectomy. Bronchial granular cell tumors are benign neoplasms that typically present with recurrent pneumonia. Imaging may demonstrate an endobronchial lesion or an associated post-obstructive opacity, but diagnosis requires tissue sampling...

OBJECTIVE: Studies have questioned the long-term health effects of offspring conceived after fertility treatments. METHODS: We aimed to evaluate whether an association exists between mode of conception (in vitro fertilization, ovulation induction, or spontaneous pregnancy) and neoplasm risk (both benign and malignant tumors) among the offspring; we observed the offspring for up to 18 years. STUDY DESIGN: A population-based cohort analysis was performed that compared the risk for neoplasms among children (up to the age of 18 years) based on mode of conception...

BACKGROUND: Pilocytic astrocytomas (PAs) are the most common pediatric central nervous system neoplasms. In the majority of cases these tumors are benign and receive favorable prognosis following gross total surgical resection. In patients with progressive or symptomatic tumors, aggressive surgical resection is generally not feasible, thus radiation or chemotherapy are accepted initial or adjuvant interventions. Due to serious long-lasting side-effects, radiation is limited in young children; therefore, chemotherapy is widely practiced as an adjuvant treatment for these patients...

Pediatric multiple sclerosis accompanied by a tumefactive demyelinating lesion (TDL) is extremely rare. Because it is very difficult to distinguish TDLs from neoplasms, invasive brain biopsies are required for a definitive diagnosis. MR spectroscopy (MRS) without brain biopsy was recently shown diagnostic in some patients with TDLs, based on the elevation of glutamate/glutamine peaks. This report describes the clinical course of a 9-year-old girl with multiple sclerosis following a TDL and discusses the usefulness of MRS and brain biopsies to diagnose TDLs...

Lipoblastoma is a rare neoplasm of embryonal adipose tissue most often encountered on the trunk and extremities of children. It commonly presents as a painless subcutaneous soft tissue mass, but there are other unique clinical presentations that are important to recognize. The differential is broad and includes sarcoma, vascular tumor, myofibroma, and other fibromatoses. We present three varied, distinct cases of pediatric lipoblastoma and review the literature on this condition.

C A Hughes, J Brown
INTRODUCTION: In the pediatric population the submandibular gland requires removal in a number of conditions including, refractory recurrent sialoadenitis, sialolithiasis, salivary gland neoplasms and debilitating sialorrhea. In comparison to the traditional trans-cervical approach, the trans-oral route avoids a cervical scar, potential keloid formation and decreased risk of injury to the marginal mandibular branch of the facial nerve. This approach also eliminates the potentiality of remnant duct disease since the entire duct and papillae are removed...

Patients with congenital thrombocytopenia have an increased risk of developing myeloid neoplasms. In these cases, the morphologic distinction between disease at baseline and at progression is challenging. This report analyzes clinicopathologic features of congenital thrombocytopenia with long-term follow-up at one referral center. Records from the last 20 years were searched for cases of congenital thrombocytopenia with bone marrow biopsies and peripheral blood smears. The clinical, morphologic, immunophenotypic, and molecular features were analyzed...

PURPOSE: To compare the extended dose profile delivered by 3DCRT and VMAT techniques for flattened and flattening-filter-free(FFF) photon beams (6X, 6XFFF,10XFFF), with and without jaw-tracking (JT) on Varian TrueBeam linac. The goal is to determine which treatment technique/modality will minimize the peripheral photon dose exposure (and ultimately minimize the risk of second malignant neoplasms (SMN)) in pediatric patients. METHODS: 3DCRT, VMAT, and jaw tracking VMAT (JTVMAT) plans with 6X, 6XFFF and 10XFFF x-ray beams were created on a 30×60×22...

BACKGROUND: Accurate and rapid diagnosis of extrapulmonary nodal tuberculosis in children is of paramount importance in order to initiate immediate treatment and prevent complications. Fine needle aspiration biopsy (FNAB) provides a means of triage, and also identifies patients with suspected hematological or metastatic neoplasms.This study aims to demonstrate how a laboratory-run FNAB service, which largely replaced the previous surgical practice of lymph node excision biopsy can provide a clinically acceptable and effective diagnostic service...

BACKGROUND: Conventional cytology (CC) is a well-established and effective methodology for the evaluation of pediatric tumors. Liquid-based cytology (LBC) is a better technique of smear preparation and is at present the standard protocol in cervical cytology samples. AIMS: In the present study, we analyzed both smear preparatory techniques in fine-needle aspiration (FNA) samples from solid pediatric neoplasms in terms of adequacy and efficacy with objectives to study the changes in background and morphology of tumor cells in LBC smears...
