Abstract
PURPOSE This single-center retrospective study explores the safety and efficacy of 177 Lu-DOTATATE in children and young adult population with metastatic/inoperable neuroendocrine tumors (NETs). PATIENTS AND METHODS This study is a retrospective analysis of all children and young adult patients (≤29 years) with advanced inoperable/metastatic epithelial or nonepithelial NETs who were administered a median of 4 cycles of 177 Lu-DOTATATE therapy and low-dose oral capecitabine as a radiosensitizer every 8-12 weeks, except 2 patients who received CAPTEM chemotherapy. The radiological response was assessed using RECIST 1.1 on interim and end-of-treatment 68 Ga-DOTANOC PET/CT. The primary endpoint was objective response rate, whereas disease control rate, toxicity profile, progression-free survival, and overall survival were secondary endpoints. RESULTS Nineteen biopsy-proven NET patients (median age, 22 ± 10 years) with 8 of them adolescents (10-18 years) and the remaining young adults (19-29 years) were included. Fourteen patients had gastroenteropancreatic neuroendocrine tumor (pancreas being most common primary site), whereas the rest had non-gastroenteropancreatic neuroendocrine tumor. A total of 65 cycles of 177 Lu-DOTATATE (range, 1-6 cycles) were administered with a median cumulative activity of 600 mCi (range, 100-1000 mCi). The objective response rate and disease control rate were 41% and 94%, respectively. Grade 1 and 2 adverse events were observed in 14 (74%) and 5 (26%) of 19 patients, respectively. In a total of 8 events (42%), 4 events each of disease progression and death occurred during a median follow-up of 80.1 months with an estimated 5-year progression-free survival and overall survival of 54% (95% confidence interval, 30-78) and 63% (95% confidence interval, 39-87), respectively. CONCLUSIONS 177 Lu-DOTATATE appears safe and effective in children and young adults with metastatic/inoperable NETs. Large prospective trials are required to validate these results.

Abstract
Pleuropulmonary blastoma (PPB) is a very rare tumor of the chest seen predominantly in young children with great heterogeneity and clinical, biochemical, and biological complexity and recognized, described, and classified as distinct from the pulmonary blastoma typically encountered in adults. Unfortunately, it has a poor and dismal prognosis and is mainly classified as cystic (type 1), mixed type (type 2), and solid (type 3). Herein, we present one case of PPB type 2 presenting clinically with a right pulmonary abscess, a rare clinical presentation of PPB, which was initially treated with surgery, and after approximately 1 year of follow-up, pulmonary rest-recurrence and central nervous system secondary deposits were detected. When a large pleural-based mass is identified in a young child, PPB should also be considered, especially in a patient with a positive oncological family history. Suggestive findings include the absence of chest wall invasion, presence of pleural fluid, right-sided location, and heterogeneous native (NECT) low attenuation with variable postcontrast enhancement. The authors believe that a modern therapeutic approach should consider these results for a better understanding of the genetic nature and complex mechanism and process of PPB disease development (both clinical and preclinical data concerning PPB pathophysiology are still lacking and are not completely understood) so that it would be possible to establish new possible therapeutic options (i.e. nuclear medicine theranostics in PPB treatment, developments and innovation in FLASH radiotherapy and proton therapy) and approaches, and so that, given the severity of the disease, it would be possible to indicate the importance of genetic testing and counseling of close relatives. In line with the previous, the rapid development of artificial intelligence could potentially bring the development of a novel fusion of radio mics and semantic features and MRI-based machine learning in distinguishing PPB from similar pathology.

Abstract
Primary pediatric lung tumors are uncommon and have many overlapping clinical and imaging features. In contrast to adult lung tumors, these rare pediatric neoplasms have a relatively broad histologic spectrum. Informed by a single-institution 13-year retrospective record review, we present an overview of the most common primary pediatric lung neoplasms, with a focus on the role of positron emission tomography (PET), specifically 18F-fluorodeoxyglucose (FDG) PET and 68Ga-DOTATATE PET, in the management of primary pediatric lung tumors. In addition to characteristic conventional radiographic and cross-sectional imaging findings, knowledge of patient age, underlying cancer predisposition syndromes, and PET imaging features may help narrow the differential. While metastases from other primary malignancies remain the most commonly encountered pediatric lung malignancy, the examples presented in this pictorial essay highlight many of the important conventional radiologic and PET imaging features of primary pediatric lung malignancies.

Abstract
INTRODUCTION Pleuropulmonary blastoma (PPB) is a rare, aggressive, primary intrathoracic malignancy typically seen in infancy and early childhood. Accurate distinction from congenital cystic lung lesions is crucial due to significant prognostic and therapeutic differences. Cytologic features have rarely been described. Establishing a cytodiagnosis is challenging owing to its rarity, lack of awareness, and multiple morphologic mimics. MATERIALS AND METHODS This was a retrospective study conducted over 8 years. The histopathology and cytopathology databases were searched for all pediatric PPB cases. The corresponding cytologic samples were reviewed to identify characteristic features that can help distinguish PPB from its mimics. RESULTS There was a total of six cases of pediatric PPB reported during the study period. Of these, four (66.7%) presented as intrathoracic, and two (33.3%) as pleural-based masses. Cytology smears showed discretely scattered and perivascular arrangements of round-oval tumor cells with background eosinophilic stromal material. The tumor cells were mildly pleomorphic (n = 3) with round nuclei, fine chromatin, inconspicuous nucleoli, and scanty cytoplasm; however, three cases showed marked anaplasia, and one each showed necrosis and rhabdoid differentiation. On immunocytochemistry (4/6), these were positive for vimentin and desmin and negative for WT1, chromogranin, SALL4, cytokeratin, CD45, and CD99. FISH (1/6) did not show N-Myc amplification. CONCLUSIONS Knowledge of the characteristic cytomorphological and immunocytochemical features of PPB is vital to establish a prompt and accurate cytodiagnosis with appropriate clinicoradiologic correlation.

Abstract
BACKGROUND. Although primary lung cancer is rare in children, chest CT is commonly performed to assess for lung metastases in children with cancer. Lung nodule computer-aided detection (CAD) systems have been designed and studied primarily using adult training data, and the efficacy of such systems when applied to pediatric patients is poorly understood. OBJECTIVE. The purpose of this study was to evaluate in children the diagnostic performance of traditional and deep learning CAD systems trained with adult data for the detection of lung nodules on chest CT scans and to compare the ability of such systems to generalize to children versus to other adults. METHODS. This retrospective study included pediatric and adult chest CT test sets. The pediatric test set comprised 59 CT scans in 59 patients (30 boys, 29 girls; mean age, 13.1 years; age range, 4-17 years), which were obtained from November 30, 2018, to August 31, 2020; lung nodules were annotated by fellowship-trained pediatric radiologists as the reference standard. The adult test set was the publicly available adult Lung Nodule Analysis (LUNA) 2016 subset 0, which contained 89 deidentified scans with previously annotated nodules. The test sets were processed through the traditional FlyerScan (github.com/rhardie1/FlyerScanCT) and deep learning Medical Open Network for Artificial Intelligence (MONAI; github.com/Project-MONAI/model-zoo/releases) lung nodule CAD systems, which had been trained on separate sets of CT scans in adults. Sensitivity and false-positive (FP) frequency were calculated for nodules measuring 3-30 mm; nonoverlapping 95% CIs indicated significant differences. RESULTS. Operating at two FPs per scan, on pediatric testing data FlyerScan and MONAI showed significantly lower detection sensitivities of 68.4% (197/288; 95% CI, 65.1-73.0%) and 53.1% (153/288; 95% CI, 46.7-58.4%), respectively, than on adult LUNA 2016 subset 0 testing data (83.9% [94/112; 95% CI, 79.1-88.0%] and 95.5% [107/112; 95% CI, 90.0-98.4%], respectively). Mean nodule size was smaller (p < .001) in the pediatric testing data (5.4 ± 3.1 [SD] mm) than in the adult LUNA 2016 subset 0 testing data (11.0 ± 6.2 mm). CONCLUSION. Adult-trained traditional and deep learning-based lung nodule CAD systems had significantly lower sensitivity for detection on pediatric data than on adult data at a matching FP frequency. The performance difference may relate to the smaller size of pediatric lung nodules. CLINICAL IMPACT. The results indicate a need for pediatric-specific lung nodule CAD systems trained on data specific to pediatric patients.

Abstract
Pulmonary tumors in childhood are rare, but the majority are malignant. The histopathologic spectrum is quite diverse, including inflammatory myofibroblastic tumor, hamartoma, primary pulmonary paraganglioma, carcinoid tumor, mucoepidermoid carcinoma, pleuropulmonary blastoma, adenocarcinoma, squamous cell carcinoma, and sarcomas. Nonspecific clinical and radiological findings result in late and incorrect diagnoses. Although surgical resection is the initial and proper treatment method, additional adjuvant therapy is dependent on both tumor stage and histopathologic type.

Abstract
Primary pulmonary salivary gland-type tumours are rare neoplasms that are thought to arise from seromucinous glands that are located in the submucosa of large airways. These neoplasms have clinical and pathologic features that are distinct from other pulmonary neoplasms. The majority of primary pulmonary salivary gland-type tumours are malignant, with the most common entities being mucoepidermoid carcinoma, adenoid cystic carcinoma, and epithelial-myoepithelial carcinoma. Less commonly seen are myoepithelial carcinoma, hyalinizing clear cell carcinoma, acinic cell carcinoma, secretory carcinoma, salivary duct carcinoma, intraductal carcinoma, and polymorphous adenocarcinoma. Benign salivary gland-type tumours of the lung include pleomorphic adenoma and sialadenoma papilliferum. Morphologic, immunophenotypic, and molecular features of these neoplasms are largely similar to salivary gland tumours elsewhere, and therefore the exclusion of metastatic disease requires clinical and radiologic correlation. However, the differential diagnostic considerations are different in the lung. The distinction of salivary gland-type tumours from their histologic mimics is important for both prognostication and treatment decisions. Overall, salivary gland type-tumours tend to have a more favourable outcome than other pulmonary carcinomas, although high-grade variants exist for many of these tumour types. Recent advances in our understanding of the spectrum of salivary gland-type tumours reported in the lung and their diversity of molecular and immunohistochemical features have helped to refine the classification of these tumours and have highlighted a few differences between salivary gland-type tumours of the lung and those primary to other sites.

Abstract
Fetal lung interstitial tumor (FLIT) is an extremely rare pediatric lung tumor that shares radiological features with congenital pulmonary malformations (cPAM) and other lung neoplasms. A review of the literature, together with the first European case, are herein reported. A systematic and manual search of the literature using the keyword "fetal lung interstitial tumor" was conducted on PUBMED, Scopus, and SCIE (Web of Science). Following the PRISMA guidelines, 12 articles were retrieved which describe a total of 21 cases of FLIT, and a new European case is presented. A prenatal diagnosis was reported in only 3 out of 22 (13%) cases. The mean age at surgery was 31 days of life (1-150); a lobectomy was performed in most of the cases. No complications or recurrence of disease were reported at a mean follow-up of 49 months. FLIT is rarely diagnosed during pregnancy, may present at birth with different levels of respiratory distress, and requires prompt surgical resection. Histology and immunohistochemistry allow for the differentiation of FLIT from cPAM and other lung tumors with poor prognosis, such as pleuropulmonary blastoma, congenital peri-bronchial myofibroblastic tumor, inflammatory myofibroblastic tumor, and congenital or infantile fibrosarcoma.

Abstract
Pleuropulmonary blastoma (PPB) is a tumor occurring almost exclusively in infants and young children. This is the most common primary-lung malignancy in childhood. There is age-associated progression through a distinctive sequence of pathologic changes, from a purely multicystic lesion type I to a high-grade sarcoma type II and III. While complete resection is the cornerstone treatment for type I PPB, aggressive chemotherapy with a less favorable prognosis is associated with type II and III. DICER1 germline mutation is positive in 70% of children with PPB. Diagnosis is challenging, as it resembles congenital pulmonary airway malformation (CPAM) in imaging. Although PPB is an extremely rare malignancy, over the past five years we have encountered several children diagnosed with PPB in our medical center. Herein, we present some of these children and discuss diagnostic, ethical, and therapeutic challenges.

Abstract
Primary tumors of the airways in the pediatric population are very rare entities. For this reason, little is known about the pathogenesis of these neoplasms. Understanding the biology has different practical implications: for example, it could help in the differential diagnosis, have a prognostic significance, or may lead to the development of a targeted therapy. The aim of this article is to present the current knowledge about pediatric airways tumors, focusing on the molecular mechanisms that cause the onset and progression of these neoplasms. After a brief introduction of epidemiology and clinical presentation, the tumorigenesis of the most frequent pediatric airways tumors will be described: Juvenile-onset recurrent respiratory papillomatosis (JORRP), Subglottic Hemangiona (SH), Rhabdomyosarcoma (RMS), and Mucoepidermoid carcinoma (MEC).

Abstract
The second most common abdominal tumor in children is Wilms' tumor, and the lung is where it most often metastasizes. The typical metastases are multiple, peripherally located, round, and variable-sized nodules. Atypical patterns are also possible and may create diagnostic challenges, especially in patients treated with chemotherapy. Among these, cavitating metastases are an anecdotal type of atypical secondary lung lesions. Here, we report a case of a chemotherapy-induced cavitating Wilms' tumor pulmonary metastasis discovered during the follow-up for an anaplastic nephroblastoma in a 6-year-old girl. Furthermore, we conducted a review of the existing literature on this exceedingly rare radiological pattern to establish its best management.

Abstract
Neuroendocrine neoplasms (NENs) encompass a variety of neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) which can arise anywhere in the body. While relatively rare in the pediatric population, the incidence of NENs has increased in the past few decades. These neoplasms can be devastating if not diagnosed and treated early, however, symptoms are variable and can be indolent for many years. There is a reported median of 10 years from the appearance of the first symptoms to time of diagnosis. Considering some of these neoplasms have a mortality rate as high as 90%, it is crucial healthcare providers are aware of NENs and remain vigilant. With better provider education and easily accessible resources for information about these neoplasms, awareness can be improved leading to earlier disease recognition and diagnosis. This manuscript aims to provide an overview of both the most common NENs as well as the rarer NENs with high lethality in the pediatric population. This review provides up to date evidence and recommendations, encompassing recent changes in classification and advances in treatment modalities, including recently completed and ongoing clinical trials.

Abstract
Mucoepidermoid carcinoma (MEC) is the most common malignancy of minor salivary glands in adults. Pulmonary MEC is extremely uncommon, comprising only 0.1–0.2% of the primary lung malignancies and <1% of primary bronchial tumors. It is even rarer in children, and literature is limited to a few case reports only. Here we present a case report of a 9-year-old boy diagnosed with primary MEC of the trachea along with a review of the literature. A 9-year-old male child presented with complaint of dry cough for two years which was later associated with shortness of breath after one year. Bronchoscopic examination revealed a growth arising from right lateral wall of carina occluding 50% of the lumen and detailed histopathological examination revealed it to be a MEC of the trachea. The patient underwent local excision of the tumor with primary anastomosis. Because of positive margin, adjuvant radiotherapy of 60 Gy in 30 fractions was given to the tumor bed. The patient tolerated the treatment well and is disease free at 6 months follow-up. Experience with MEC of the trachea in children is limited, and optimal treatment protocols have not been defined, with current treatment mainly extrapolated from MEC of the salivary glands.

Abstract
BACKGROUND Primary lung malignancies are a heterogeneous group of cancers that occur very rarely in childhood. Due to limited knowledge of their epidemiologic and clinical features, these tumors present a challenge to the treating physicians. This study aimed to increase the knowledge about the occurrence of primary lung malignancies in childhood in Germany. MATERIALS AND METHODS Pseudonymized data of cases recorded at the German Center for Cancer Registry Data (ZfKD) between 1990 and 2017 were retrieved. Primary lung malignancies were identified using the ICD- and ICD-O classification. Numbers were compared to those reported to the German Childhood Cancer Registry (GCCR). Crude incidence rates were calculated using the ZfKD database. RESULTS A total of 168 patients diagnosed with primary lung malignancies in the age below 19 years were identified from the ZfKD. The median age at diagnosis was 13 years. The most common tumor entities were lung carcinoids (n = 49), lung carcinoma (n = 36), and pleuropulmonary blastoma (n = 14). An unexpected accumulation of lung cancer cases was noted in the first year of life without a clearly specified histopathological diagnosis. A substantial discrepancy in the numbers of primary lung malignancies between ZfKD and GCCR was found. CONCLUSIONS We present population-based data on the occurrence of primary childhood lung malignancies in Germany, which were more frequent than previously anticipated but likely remained underreported. For better understanding and optimal treatment of these entities, cancer registration needs to be improved through mandatory reporting to the GCCR and regular data sharing between GCCR, population-based and clinical cancer registries.

Abstract
Pulmonary inflammatory myofibroblastic tumor (IMT) is a rare condition in the normal population and specifically in the pediatric population. We reported a 9‐year‐old male child who presented with cough and intermittent fever and weight loss that was most suggestive of the infectious process. We reviewed the consideration of diagnosis and treatment. Pulmonary IMT is a rare pulmonary mass that might be asymptomatic or manifest by hemoptysis, cough, constitutional symptoms, and pneumonia. It should be in the mind that IMT might mimic neoplasms, by history, radiology, and clinical aspects.

Abstract
Mucoepidermoid carcinoma (MEC) is an uncommon type of salivary gland tumor that can present as an endobronchial neoplasm, most commonly in the adult population. Neuroendocrine carcinoid tumors comprise the majority of bronchial neoplasms in the pediatric population and are nearly indistinguishable from MEC on imaging. We present a rare case of MEC in a 3-year-old presenting with recurrent symptoms of lower airway obstruction and discuss its typical associated symptoms and imaging features.

Abstract
BACKGROUND Inflammatory myofibroblastic tumors (IMT) are rare, intermediate malignant tumors harboring frequent somatic molecular rearrangements. The management of IMT has not been standardized. METHODS A retrospective multicenter study was conducted on all pediatric patients treated for IMT between 2000 and 2019. RESULTS This series included 39 cases of IMT, with a median age at diagnosis of 7 years (range 20 days to 16 years). Tumor location included pelvis-abdomen (n = 16), thorax (n = 14), head and neck (n = 7), and limbs (n = 2). One patient had metastatic disease. Immunochemistry showed 21/39 (54%) anaplastic lymphoma kinase (ALK)-positive tumors. Somatic tyrosine kinase rearrangement was present in 31/36 (86%) of the tumors analyzed: 21 ALK, five ROS1, and five NTRK. Immediate surgery was performed in 24 patients (62%), with adjuvant therapy for three patients. Delayed surgery after neoadjuvant therapy was possible in 10 cases. Exclusive systemic therapy was delivered to four patients; one patient with orbital IMT was managed by watchful waiting. After a median follow-up of 33 months (range 5-124), eight (20%) recurrences/progressions occurred after surgery (seven after primary surgery and one after delayed surgery), after a median interval of 7 months (range 2-21), all in thoracic locations. The 3-year overall and disease-free survivals were 96.8% (95% CI: 79.2%-94.0%) and 77.4% (95% CI: 59.6%-88.1%), respectively. Relapses/progressions were more common in patients with a thoracic primary (p < .001) or after incomplete surgery with no adjuvant therapy (p = .027). CONCLUSION Surgery is effective in most cases of pediatric IMT. Systematic analysis of tyrosine kinase rearrangement is recommended. When the tumor is deemed only partially resectable to preserve organs and function, neoadjuvant therapy may be proposed to allow adequate conservative surgery.

Abstract
Ewing’s sarcoma family of tumors (ESFTs) contains multiple tumors with similar histological and immunohistochemical features. ESFTs are small, round cell, highly malignant tumors that arise from the neuroectoderm of bone and extraskeletal soft tissue. Ewing’s sarcoma is the second most common primary malignant bone cancer in children and adolescents, with the second decade of life being the most common age of diagnosis. In this article, we present a case of a young male who presented to the emergency department complaining of shortness of breath and cough and was later diagnosed with Ewing’s sarcoma of the chest wall, which is also called Askin’s tumor, and it is an extremely rare disease with only 17 cases reported in the literature.

Abstract
Pleuropulmonary blastomas are rare, potentially aggressive embryonal cancers of the lung parenchyma and pleural surfaces that account for 0.25%-0.5% of primary pulmonary malignancies in children. Pleuropulmonary blastomas are classified as cystic (type I), mixed cystic and solid (type II), and solid (type III). Pleuropulmonary blastoma occurs in the same age group (0-6 years) as other more common solid tumors such as neuroblastoma and Wilms tumor. Differential diagnosis includes metastasis from Wilms tumor and macrocystic congenital pulmonary airway malformation (CPAM). A key pathologic and genetic discriminator is the DICER1 germline mutation found in patients with pleuropulmonary blastoma. Imaging, histopathologic, and clinical data are important to use in conjunction in order to determine the diagnosis and risk stratification of pleuropulmonary blastomas. Survival varies from poor to good, depending on type. However, the spectrum of pleuropulmonary blastoma is insufficiently understood due to the variable presentation of this rare disease. We present a current review of the literature regarding pleuropulmonary blastomas in this article.

Abstract
Background: Although the use of video-assisted thoracoscopic surgery (VATS) for resection of lung metastases has increased, surgeons still advocate for open resection as it permits palpation of lesions that may be missed on imaging. This study aimed to compare the utilization of open thoracotomy versus VATS over time and determine if the use of VATS changes perioperative outcomes. Methods: Using the Kids' Inpatient Database (2006, 2009, 2012, 2016), we identified children (age ≤20) with a diagnosis of secondary lung cancer with either lobectomy or sublobar resection coded during the same admission. Utilization was compared across years for the overall cohort and for patients with primary bone and connective tissue (PBCT) cancers. We defined prolonged length of stay (LOS) as LOS ≥75th percentile (LOS ≥7 days). Univariable and multivariable analyses compared in-hospital complication rates and LOS for open and VATS approaches. Results: Of the 1316 children (539 female) undergoing pulmonary resection, VATS was utilized in 374 (28.4%). Utilization increased rapidly from 2006 to 2009 (P < .001 for trend), but stabilized thereafter (P = .622). Metastatic PBCT cancers were the most common indication for resection (n = 496, 38%), but open and VATS approaches were used nearly equally (P = .368). Overall, 352 (26%) patients had complications. On multivariable analysis, the open approach remained independently associated with increased complications (odds ratio [OR] 1.48, 95% confidence interval [CI] [1.04-2.11]). Median LOS increased for open cases (5 versus 3 days, P < .001). Furthermore, open metastasectomy was associated with prolonged LOS (OR 1.50, [1.07-2.10]) after controlling for age, sex, primary cancer, reporting year, resection extent, obesity, complications, and nonoperative intubation. Conclusion: VATS approach to pulmonary metastasectomy resulted in fewer complications and shorter LOS in a nationwide sample of children. Despite these advantages, the use of VATS has plateaued. While this study cannot comment on oncologic safety or long-term outcomes, future studies should evaluate whether indications for VATS pulmonary metastasectomy can be expanded.

CT-guided hook-wire localization of pulmonary nodules in children prior to atypical resection by thoracoscopy: Practical aspects. RADIOLOGIA 2021; 63:415-424.

Abstract
In the multidisciplinary treatment of pediatric oncologic patients, multiple imaging tests, biopsies, and resections are required for diagnosis, initial staging, and posterior restaging. In these patients, pulmonary nodules are not always metastases, so the correct diagnosis of these lesions affects their treatment and the patient's survival. Percutaneous localization of pulmonary nodules is key for two reasons: it enables the surgeon to resect the smallest amount of lung tissue possible and it guarantees that the nodule will be included in the resected specimen. Without percutaneous localization, it can be impossible to accomplish these two objectives in patients with very small nodules that are separated from the pleural surface and therefore impossible to see by thoracoscopy. This article reviews the technique for hook-wire localization of pulmonary nodules and the keys to ensuring the best results.

Abstract
Pulmonary nodules present a diagnostic challenge when they appear as atypical metastases in pediatric oncology patients. Chest computed tomography (CT) is the primary imaging modality for assessing lung nodules. In pediatric populations, Wilms tumor and osteosarcoma are the cancers most likely to produce pulmonary metastasis, both typical and atypical. This pictorial essay provides a thorough description of the specific radiologic features of atypical pediatric pulmonary metastases, and their pathogenesis and differential diagnosis. We also address diagnostic approaches to incidental lung nodules in healthy children found in the literature. Our aim is to help radiologists identify atypical lung metastases on CT, ensuring that children receive prompt, and potentially lifesaving, treatment.

Abstract
Pleuropulmonary blastoma (PPB) is a rare but aggressive pediatric tumor originates from either lung or pleura. It was recently linked to the DICER I mutation as a part of predisposition syndrome for different type of tumor. It is characterized histologically by a primitive, variably mixed blastomatous and sarcomatous tissue. PPB is classified into four subtypes: cystic (type I and type Ir); cystic and solid (type II); solid (type III). PPB has no characteristic imaging findings. Integrated imaging can help to make a differential diagnosis and to recognize the subtypes in order to set up therapy. An early recognition and differentiation from congenital airway malformations and other benign cysts are very important. The treatment consists in a multimodal therapy including surgery and chemoterapy. We report a case of 3 years old female admitted at our hospital with fever, non productive cough and dyspnea, who was diagnosed with type II PPB.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare disease that mainly involves the lung and the abdomen with an intermediate clinical course but a recurrence rate between 15–30%. Radical surgery represents the gold standard of treatment, while chemotherapy and radiotherapy are considered for unresectable lesions. The identification of ALK translocations in IMT opened the option for the use of target therapies. Indeed, the ALK inhibitors have changed the treatment approach for aggressive lesions, improving the prognosis. Intraluminal upper-way IMT is extremely rare and represents a medical challenge. We reported an endotracheal IMT case presenting a previously unknown TRAF3-ALK fusion transcript.

Abstract
Pediatric cancer is a life threatening disease known to create multi-organ complications that further compromise medical management affecting patient morbidity and mortality. Pulmonary hypertension (PH) is becoming more recognized as a complication of cancer and its therapies but has not been well characterized in pediatrics. Cancer pathophysiology can be uniquely set up to promote pulmonary vascular injury and remodeling that is similar to PH patients without cancer. This highlights the need to evaluate for PH clinically and with routine testing such as echocardiography during the course of a patient's care even into adulthood. This review article will discuss the direct, indirect and therapy related aspects of cancer which can promote PH in these patients. This understanding is essential to target effective treatment options in a potentially fatal complication. Diagnostic and treatment algorithms are presented in relation to the most recent pediatric PH management guidelines.

Abstract
Gastrointestinal stromal tumors and neuroendocrine tumors in adult and pediatric populations differ immensely. Despite these established differences, the extreme rarity of gastrointestinal stromal tumors and neuroendocrine tumors in the pediatric population has resulted in the lack of consensus management guidelines, making optimal surgical approaches unclear. Comprehensive management principles to guide surgical approaches in adult literature are extensive. However, these are still lacking for pediatric patients. International cooperation to develop standardized pediatric-specific guidelines is urgently warranted in the future. This article highlights the vast differences between adult and pediatric parameters and provides recommendations on optimal and novel surgical approaches in children.

Abstract
Salivary gland tumors are uncommon primary lesions in the lung. Their morphologic, immunophenotypic, and molecular characteristics resemble those of their counterparts in the head and neck or elsewhere. Most common primary pulmonary salivary gland tumors include mucoepidermoid carcinoma, adenoid cystic carcinoma, and epithelial-myoepithelial carcinoma. The study of these neoplasms is hampered by their paucity. Therefore, studies are in general small or restricted to individual cases. Despite this challenge recent advances have been made specifically at the molecular level. Molecular alterations such as MAML2 rearrangements in mucoepidermoid carcinoma, MYB rearrangements in adenoid cystic carcinomas, and EWSR1 rearrangements in hyalinizing clear cell carcinomas and myoepithelial tumors have been identified. These molecular alterations might be helpful in the distinction of these salivary gland tumors from other neoplasms in the lung. However, the distinction from metastatic disease remains challenging. Awareness of these tumors and knowledge of available ancillary studies to confirm the diagnosis is important to avoid misdiagnosis which might lead to differences in treatment, management, and prognosis. Further studies are needed to identify biomarkers to better predict patient's outcome and for individual management and treatment of patients.

Abstract
BACKGROUND Primary pediatric lung malignancies are rare tumors. We provide an updated analysis of the epidemiology and prognosis of these tumors since the last SEER series published in 2009. METHODS The SEER 18 database from 1975 to 2016 was analyzed for patients ages 0-19 years with primary lung and/or bronchus neoplasms. RESULTS 348 patients met inclusion criteria. The majority were white and ≥12 years of age. The most common histologies were neuroendocrine (41.4%) and blastoma (16.4%). 75.4% of patients had local-regional disease and 81.4% underwent surgery. Significant differences between histologies were seen for age, year at diagnosis, tumor laterality and location, stage, and treatment type. Median survival was 36.6 years (95% CI 33.3-37.4). Blastoma (HR 3.47) and squamous cell (HR 6.26) carried a significantly higher risk of death than neuroendocrine cancer diagnosis. CONCLUSION Primary pediatric lung malignancies are rare, long-term survival is favorable but histology-dependent. Surgery continues to be an important treatment modality.

Abstract
In pediatric patients with sarcomas, hepatoblastomas, or other types of primary tumors, lung metastases are often found at diagnosis or during follow-up. The wide variety of primary tumors and clinical situations makes management and follow-up of these patients challenging. Chest CT is the best way to detect the dissemination of disease to the lungs. Many pulmonary nodules are nonspecific, and many might not be pathological. Others have characteristics that make them suspicious. Although there are some general features that indicate that a pulmonary nodule is likely to be a metastasis, sometimes the meaning of these features depends on the primary tumor. Furthermore, metastases can develop during the course of the disease, and the protocols for follow-up are different for different primary tumors. We review the different protocols used at our hospital for the primary tumors that most often metastasize to the lungs, including the criteria for lung metastases and the follow-up for each primary tumor.

Abstract
Pulmonary metastases typically present as well-circumscribed solid nodules, often with a basilar and peripheral distribution due to hematogenous spread. When an atypical pattern of metastasis occurs, a lack of recognition may result in understaging or a delay in diagnosis. The purpose of this article is to review the imaging findings of atypical pulmonary metastatic disease in children. Atypical pulmonary metastatic patterns that can be seen in children include cavitary lesions, calcified pulmonary nodules, nodules with peritumoral halos, tree-in-bud or strial pattern secondary to tumor in peripheral pulmonary arterial branches, lymphangitic carcinomatosis, and miliary disease. An awareness of the spectrum of imaging findings of atypical pulmonary metastases along with an understanding of histopathological underpinnings will allow the radiologist to make an accurate diagnosis.

Abstract
Hematological and oncological disorders represent leading causes of childhood mortality. Neuropeptide somatostatin (SST) has been previously demonstrated in various pediatric tumors, but limited information exists on the expression and characteristics of SST receptors (SSTR) in hematological and oncological disorders of children. We aimed to investigate the expression of mRNA for SSTR subtypes (SSTR-1–5) in 15 pediatric hematological/oncological specimens by RT-PCR. The presence and binding characteristics of SSTRs were further studies by ligand competition assay. Our results show that the pediatric tumor samples highly expressed mRNA for the five SSTR subtypes with various patterns. The mRNA for SSTR-2 was detected in all specimens independently of their histological type. A Hodgkin lymphoma sample co-expressed mRNA for all five SSTR subtypes. SSTR-3 and SSTR-5 were detected only in malignant specimens, such as rhabdomyosarcoma, Hodgkin lymphoma, acute lymphoblastic leukemia, and a single nonmalignant condition, hereditary spherocytosis. The incidence of SSTR-1 and SSTR-4 was similar (60%) in the 15 specimens investigated. Radioligand binding studies demonstrated the presence of specific SSTRs and high affinity binding of SST analogs in pediatric solid tumors investigated. The high incidence of SSTRs in hematological and oncological disorders in children supports the merit of further investigation of SSTRs as molecular targets for diagnosis and therapy.

Abstract
Pediatric cystic lung lesions have long been a source of confusion for clinicians, radiologists, and pathologists. They encompass a wide spectrum of entities with variable prognostic implications, including congenital lung malformations, pulmonary neoplasms, and hereditary conditions. As our understanding of the developmental and genetic origins of these conditions has evolved, revised nomenclature and classifications have emerged in an attempt to bring clarity to the origin of these lesions and guide clinical management. This review discusses cystic lung lesions and the current understanding of their etiopathogenesis.

Abstract
BACKGROUND Pulmonary blastoma (PB) is a rare lung primary malignancy with poorly understood risk factors and prognosis. We sought to investigate the epidemiologic features and long-term outcomes of PB. METHODS A population-based cohort study was conducted to quantify the death risk of PB patients. All subjects diagnosed with malignant PB from 1988 to 2016 were screened from the Surveillance, Epidemiology and End Results database. Cox regression model of all-cause death and competing risk analysis of cause-specific death were performed. RESULTS We identified 177 PB patients with a median survival of 108 months. The 5 and 10-year survival rate in all PB patients were 58.2 and 48.5%, as well as the 5 and 10-year disease-specific mortality were 33.5 and 38.6%. No sex or race disparities in incidence and prognosis was observed. The death risk of PB was significantly associated with age at diagnosis, clinical stage, histologic subtype and surgery treatment (p<0.01). On multivariable regression analyses, older age, regional stage and no surgery predicted higher risk of both all-cause and disease-specific death in PB patients. CONCLUSION We described the epidemiological characteristics of PB and identified its prognostic factors that were independently associated with worse clinical outcome.

Abstract
Thoracic mass lesions can be categorized as originating in one of the three major compartments: a) chest wall and pleura, b) lung parenchyma and airways, c) mediastinum. While some of these, such as lymphoma, are common in both children and adults, others are rare and unique to childhood. The goal of this review is to familiarize radiologists with unusual but distinctive mass lesions of the pediatric thorax.

Abstract
Pleuropulmonary blastoma (PPB) is a potentially aggressive, rare childhood neoplasia. We investigated histopathological features, survival, and DICER1 hotspot mutations among PPB patients. Archive records at our institution were reviewed, covering a 20-year period. Thirteen children (6 males and 7 females) with a mean age of 30.5 (range 6-83) months were included. The tumor subtypes were type I in 6 (46%), type II in 4 (31%), and type III in 3 (23%). Only tumors with type II and type III histology showed anaplasia (4/7, 57%). Median follow-up was 28 (range 9-216) months. Three-year overall survival rate was 83.3% and 3-year progression-free survival rate was 25%. Progression was seen in 60% (3/5) of type I and 66.7% (4/6) of type II and type III cases. Two patients died of disseminated disease at 9 and 44 months. Hotspot missense mutations on DICER1 gene were detected in all 11 patients with available tumor tissue. We found an additional novel germline loss-of-function mutation (c.5436dupT; p.E1813*) in 1 case. To the best of our knowledge, this is the first study to investigate hotspot missense mutations on DICER1 gene among the largest series of Turkish children with PPB.

Abstract
Metastatic disease of the lung has been extensively documented in the adult patient population. The most common primary sources for pulmonary metastases include breast, colon gastrointestinal including pancreas and urinary bladder. Malignant lung tumors in pediatric population is extremely rare. However, like in adult patient population, metastases are more common than primary tumors in lung in pediatric patients. Metastatic spread of tumors can occur both by way of hematogenous spread and lymphatic pathways. We present a rare case of biopsy proven metastatic thyroid carcinoma in the lung in a 12-year-old male child masquerading as bilateral miliary nodules on imaging studies. The importance of recognition of this entity in terms of prognosis and treatment is discussed.

Abstract
Lung cancers in children under the age of 15 are very uncommon, with a scarcity of literature describing patient characteristics and survival. This study assessed first primary malignant cancers occurring in the trachea, bronchus, or lung (International Classification of Diseases for Oncology, 3rd edition [ICD-O-3] codes C33-C34) for the period 1983-2015, using data from the population-based Australian Childhood Cancer Registry. Variables of interest included morphology, sex, age group, and metastatic status at diagnosis. Mode of treatment was also assessed where possible. The Kaplan-Meier method was used to calculate 5-year observed survival. Of the 53 in-scope patients, almost half (n = 23, 43%) were diagnosed with pleuropulmonary blastoma and a further 8 (15%) had a carcinoid tumor. Few of the patients with details available on stage at diagnosis (n = 7 of 43, 16%) presented with metastatic disease. Surgical excision was the most common treatment (30 of 37 children, 81%), with two-thirds (n = 28 of 43, 65%) receiving chemotherapy. Five-year observed survival was estimated to be 74% (95% CI = 61%-85%). Our results represent one of the largest and most complete population-based cohorts of children with primary malignant lung cancers available to date. Detection of childhood lung cancer can be difficult due to the rarity of this disease and symptoms that are typically nonspecific.

Abstract
Cancer is a leading cause of death in both adults and children, but in terms of absolute numbers, pediatric cancer is a relatively rare disease. The rarity of pediatric cancer is consistent with our current understanding of how adult malignancies form, emphasizing the view of cancer as a genetic disease caused by the accumulation and selection of unrepaired mutations over time. However, considering those children who develop cancer merely as stochastically "unlucky" does not fully explain the underlying aetiology, which is distinct from that observed in adults. Here, we discuss the differences in cancer genetics, distribution, and microenvironment between adult and pediatric cancers and argue that pediatric tumours need to be seen as a distinct subset with their own distinct therapeutic challenges. While in adults, the benefit of any treatment should outweigh mostly short-term complications, potential long-term effects have a much stronger impact in children. In addition, clinical trials must cope with low participant numbers when evaluating novel treatment strategies, which need to address the specific requirements of children.

Abstract
Introduction: Endobronchial granular cell tumors are uncommon in the pediatric population. Case report: A 9-year-old female presented with respiratory failure due to an endobronchial tumor. After debulking and diagnosis, she underwent thoracotomy with right upper lobe resection and bronchoplasty. Pathology demonstrated an endobronchial S-100 negative granular cell tumor, which to our knowledge, is the first such report in the literature. Conclusion: Endobronchial granular cell tumors may cause obstructive respiratory failure, are amenable to surgery, and may be S-100 negative.
