Abstract
We report two cases of malignant mesothelioma (MM) in childhood brain tumor survivors. A 40-year-old man, who was treated at the age of ten with chemotherapy and craniospinal radiotherapy (up to 54.5 Gy) for a pineal secreting non-germinomatous germ cell tumor, had persistent fever, fatigue, and weight loss. A total body CT scan revealed several pulmonary and abdominal wall nodularities. The histological examination on a biopsy diagnosed a biphasic MM. The karyotype and array-CGH of peripheral blood were normal; a FISH of tumor cells showed a breakage of locus EWSR1 (22q12.2). In this case, environmental exposure was identified (asbestos in public water tanks). His MM followed an aggressive course and resulted in death after three months. A twelve-year-old boy affected by severe neurofibromatosis type 2 (NF2) already treated with several neurosurgical exeresis and chemotherapy lines (hydroxycarbamide, bevacizumab, sirolimus), developed multiple abdominal lesions, associated with pleural effusion and weight loss. The CT scan showed the thickening of the left pleura and multiple peritoneal nodules. The cytological examination on thoracentesis diagnosed an epithelioid MM. The karyotype on paracentesis-obtained cells revealed monosomy of chromosomes 14 and 22, loss of Y, and trisomy of 6, 10, 11, 16, and 20. NGS is currently ongoing to exclude germline or somatic second hits. Importantly, no exposure to asbestos was found. Less than 2% of MMs occur below 45 years of age; it is a rare secondary tumor in cancer survivors and environmental or genetic contributing causes are often detectable on a careful investigation. Variants in NF2 are considered to be the second most common after those in BAP1. To our knowledge, this is the first child with NF2 and concurrent MM reported to date. Compared to the expected prognosis, his MM has followed a mild course, and one year after diagnosis he is still alive.

Abstract
While somatic disruptive mitochondrial DNA (mtDNA) mutations that severely affect the respiratory chain are counter-selected in most human neoplasms, they are the genetic hallmark of indolent oncocytomas, where they appear to contribute to reduce tumorigenic potential. A correlation between mtDNA mutation type and load, and the clinical outcome of a tumor, corroborated by functional studies, is currently lacking. Recurrent familial oncocytomas are extremely rare entities, and they offer the chance to investigate the determinants of oncocytic transformation and the role of both germline and somatic mtDNA mutations in cancer. We here report the first family with Hyperparathyroidism-Jaw Tumor (HPT-JT) syndrome showing the inherited predisposition of four individuals to develop parathyroid oncocytic tumors. MtDNA sequencing revealed a rare ribosomal RNA mutation in the germline of all HPT-JT affected individuals whose pathogenicity was functionally evaluated via cybridization technique, and which was counter-selected in the most aggressive infiltrating carcinoma, but positively selected in adenomas. In all tumors different somatic mutations accumulated on this genetic background, with an inverse clear-cut correlation between the load of pathogenic mtDNA mutations and the indolent behavior of neoplasms, highlighting the importance of the former both as modifiers of cancer fate and as prognostic markers.

Abstract
Eosinophilic colitis is a rare entity characterized by the presence of a high eosinophilic infiltrate into the colonic wall in symptomatic patients, more often presenting with abdominal pain or diarrhea. These characteristics distinguish eosinophilic colitis from primary colonic eosinophilia, in which patients are asymptomatic. Primary colonic eosinophilia does not need any therapy, while eosinophilic colitis requires a strict treatment, similar to that of the more codified chronic intestinal inflammatory diseases. To date the lack of codified guidelines regarding the diagnostic criteria and the eosinophil threshold values for each colonic segment are the main diagnostic challenge for eosinophilic colitis. In addition, eosinophilic colitis is a diagnosis of exclusion, once all other causes of colonic eosinophilia (food allergens, infections, drugs, etc.) have been excluded. Several treatment options are available for eosinophilic colitis, although the evidence for most of them is limited to case reports and small case series. We examine the epidemiology, etiology, pathophysiology, diagnostic criteria and therapeutic options of eosinophilic colitis reporting recent evidence from the current literature.

Abstract
A mucinous cystadenocarcinoma along with remnants of normal pancreatic tissue was discovered in the spleen of a 21-year-old woman. Extensive clinical, radiological, ultrasound and computed tomography investigation revealed that the patient's pancreas and ovaries were unremarkable. We presume an origin from heterotopic pancreatic tissue for this neoplasm and present a review of the literature in this regard.

Abstract
The FHIT gene, a member of the histidine triad gene family, is a tumor suppressor gene exhibiting deletions in the majority of human cancers. Aberrant transcripts of this gene have been found in about 50% of esophageal, stomach and colon carcinomas. Little is known about the molecular mechanisms involved in malignant transformation of the lining cells of the anus. In this study FHIT gene expression was investigated in this particular kind of human cancer. FHIT expression was comparatively analyzed at the mRNA level, by RT-PCR, in squamous anal cancers, normal anal tissue and peripheral blood samples. cDNA analyses showed variability in FHIT transcripts, without apparent effects on the predicted amino acid sequence. These different FHIT mRNAs could represent transcripts from an alternative splicing event. Our data indicate that the FHIT mRNA detected in anal cancers and in normal samples is heterogeneous. Immunohistochemical data suggest that the Fhit protein is expressed only in a fraction of the tumor cells, while it is strongly expressed in the epithelial cells of glands of the normal anal mucosa. The absence or poor expression of the Fhit protein in anal cancers suggests a role for this tumor suppressor gene product, as a risk factor, in the onset of this human cancer, as reported before for other human gastrointestinal tumors.

Abstract
OBJECTIVE The engagement of the gut microbiota in the development of symptoms and complications of diverticular disease has been frequently hypothesised. Our aim was to explore colonic immunocytes, gut microbiota and the metabolome in patients with diverticular disease in a descriptive, cross-sectional, pilot study. DESIGN Following colonoscopy with biopsy and questionnaire phenotyping, patients were classified into diverticulosis or symptomatic uncomplicated diverticular disease; asymptomatic subjects served as controls. Mucosal immunocytes, in the diverticular region and in unaffected sites, were quantified with immunohistochemistry. Mucosa and faecal microbiota were analysed by the phylogenetic platform high taxonomic fingerprint (HTF)-Microbi.Array, while the metabolome was assessed by 1H nuclear magnetic resonance. RESULTS Compared with controls, patients with diverticula, regardless of symptoms, had a >70% increase in colonic macrophages. Their faecal microbiota showed depletion of Clostridium cluster IV. Clostridium cluster IX, Fusobacterium and Lactobacillaceae were reduced in symptomatic versus asymptomatic patients. A negative correlation was found between macrophages and mucosal Clostridium cluster IV and Akkermansia. Urinary and faecal metabolome changes in diverticular disease involved the hippurate and kynurenine pathways. Six urinary molecules allowed to discriminate diverticular disease and control groups with >95% accuracy. CONCLUSIONS Patients with colonic diverticular disease show depletion of microbiota members with anti-inflammatory activity associated with mucosal macrophage infiltration. Metabolome profiles were linked to inflammatory pathways and gut neuromotor dysfunction and showed the ability to discriminate diverticular subgroups and controls. These data pave the way for further large-scale studies specifically aimed at identifying microbiota signatures with a potential diagnostic value in patients with diverticular disease.

Abstract
Purpose Clear cell sarcoma of the kidney (CCSK) is a rare pediatric renal tumor that is frequently difficult to distinguish among other childhood renal tumors due to its histological heterogeneity. This work evaluates genetic abnormalities carried by a series of CCSK samples by whole transcriptome sequencing (WTS), to identify molecular biomarkers that could improve the diagnostic process. Methods WTS was performed on tumor RNA from 8 patients with CCSK. Bioinformatic analysis, with implementation of a pipeline for detection of intragenic rearrangements, was executed. Sanger sequencing and gene expression were evaluated to validate BCOR internal tandem duplication (ITD). Results WTS did not identify any shared SNVs, Ins/Del or fusion event. Conversely, analysis of intragenic rearrangements enabled the detection of a breakpoint within BCOR transcript recurrent in all samples. Three different in-frame ITD in exon15 of BCOR, were detected. The presence of the ITD was confirmed on tumor DNA and cDNA, and resulted in overexpression of BCOR. Conclusion WTS coupled with specific bioinformatic analysis is able to detect rare genetic events, as intragenic rearrangements. ITD in the last exon of BCOR is recurrent in all CCSK samples analyzed, representing a valuable molecular marker to improve diagnosis of this rare childhood renal tumor.

Abstract
OBJECTIVES To describe the sonographic and clinical features of abdominal wall endometriosis (AWE), a frequently misdiagnosed condition. METHODS This was a retrospective study of 21 consecutive women with pathologically proven endometriosis of the abdominal wall. Ultrasonographic and Doppler examinations were performed, before surgery, with a high-frequency linear transducer. The clinical data and the results of the sonographic examinations were reviewed and described. RESULTS At ultrasound, all the nodules appeared as discrete solid masses that were less echogenic than the surrounding hyperechoic fat. The nodules had a median diameter of 20 (range, 5-50) mm and in 18/21 (86%) cases the nodules had a round/oval shape. In eight of 21 (38%) women the AWE was located at the umbilicus, in six of 21 (29%) it was between the transverse suprapubic line and the umbilicus, in five of 21 (24%) it was found along the scar of a previous Cesarean section and in two of 21 (9%) it was in the right inguinal canal. The content was homogeneously hypoechoic in 12/21 (57%) women and inhomogeneous in the other nine (43%). The outer borders were invariably ill defined. Scarce blood vessels were found by power Doppler. Cyclic or continuous spontaneous pain at the level of the AWE was present in 19/21 (91%) cases, and two (9%) patients were asymptomatic. CONCLUSIONS Hypoechoic round/oval nodules with ill-defined borders and a hyperechoic rim should raise the suspicion of abdominal wall endometriosis, even in patients with no history of endometriosis or previous laparotomic surgery. Pressing the ultrasound probe against the nodule should reinforce a suspected diagnosis because of the pain it induces.

Abstract
Pediatric adrenocortical tumors are neoplasms that only rarely occur in pediatric patients. Their clinical behavior is often unpredictable, and the histologic criteria of malignancy used in adults are not always useful in children. The aim of this study was to validate the prognostic value of the pathologic criteria of Wieneke et al and to evaluate the potential prognostic expression of matrix metalloproteinase 2 and human leucocyte-associated antigen (HLA) class II antigens in a series of 20 pediatric patients affected by adrenocortical tumors, who were enrolled in the Italian Pediatric Rare Tumor (TREP) Study between 2000 and 2007. The age range was 0 to 17.5 years (mean, 7.28 years) with a male-female ratio of 1:2. The mean follow-up was 64.4 months. The histologic diagnoses were reviewed, and the cases were classified using the criteria for malignancy proposed by Wieneke et al. The immunohistochemical expression of matrix metalloproteinase 2 and HLA class II antigens was scored by semiquantitative analysis and compared with the clinicopathologic parameters and outcome. Based on the scoring system of Wieneke et al, 7 tumors were classified as malignant; 12 tumors, as benign; and only 1 tumor, with "unpredictable behavior." In all cases, the clinical behavior was consistent with the pathologic criteria of Wieneke et al. Notably, areas of regressive myxoid changes, not included among the criteria of Wieneke et al, were observed in all but 1 case of malignant tumors and only in 2 cases of benign tumors. Matrix metalloproteinase 2 was focally to diffusely expressed in all malignant and in most benign tumors. HLA class II antigens immunoreactivity was absent in all benign tumors and restricted to rare isolated cells in most malignant tumors. Our findings confirm that the pathologic scoring system of Wieneke et al is a simple and reproducible diagnostic tool to predict prognosis in pediatric adrenocortical tumors. Unlike in their adult counterpart, the expression of matrix metalloproteinase 2 or the loss of HLA class II antigens does not discriminate between benign and malignant tumors in children. Although pediatric adrenocortical tumors seem to be similar histologically to their adult counterparts, it is likely that they have distinctive molecular features.

Abstract
Spontaneous aneurysms of the ductus arteriosus are rare complications of a patent ductus arteriosus. It is met at any age but it is most commonly seen in children under two months of age. Echocardiography is the best test to diagnose a ductus arteriosus, but actually the role of thoracoscopy is to help in differential diagnosis of mediastinal masses. Surgery should be recommended without delay, to avoid fatal complications, with the resection of the thrombosed aneurysm of the ductus arteriosus.

Abstract
We previously showed that disruptive complex I mutations in mitochondrial DNA are the main genetic hallmark of oncocytic tumors of the thyroid and kidney. We here report a high frequency of homoplasmic disruptive mutations in a large panel of oncocytic pituitary and head-and-neck tumors. The presence of such mutations implicates disassembly of respiratory complex I in vivo which in turn contributes to the inability of oncocytic tumors to stabilize HIF1alpha and to display pseudo-hypoxia. By utilizing transmitochondrial cytoplasmic hybrids (cybrids), we induced the shift to homoplasmy of a truncating mutation in the mitochondria-coded MTND1 gene. Such shift is associated with a profound metabolic impairment leading to the imbalance of alpha-ketoglutarate and succinate, the Krebs cycle metabolites which are the main responsible for HIF1alpha stabilization. We conclude that the main hallmarks of oncocytic transformation, namely the occurrence of homoplasmic disruptive mutations and complex I disassembly, may explain the benign nature of oncocytic neoplasms through lack of HIF1alpha stabilization.

Abstract
BACKGROUND & AIMS Data on the safety of bevacizumab-based therapies for patients carrying a self-expandable metallic stent (SEMS) for occlusive colon cancer are lacking. We report 2 cases of colon perforation observed in our case series of patients with SEMS for occlusive colon cancer. METHODS Patients with occlusive symptoms caused by colon cancer received a colonic stent under endoscopic and radiologic guidance. RESULTS Over a 10-month period, 28 patients with occlusive colon cancer were treated with stent placement. The stent was placed as a bridge to surgery in 12 patients who were treated surgically within 4 to 78 days after the endoscopic procedures, without any stent-related complications. Seven patients did not receive any other antitumor treatment as a result of concomitant comorbidities. Nine patients with both primary tumor and metastatic lesions were treated with medical therapy. Over a median follow-up period of 131 days colonic perforation occurred in the 2 patients treated with a combination of capecitabine and oxaliplatin plus bevacizumab. CONCLUSIONS Further studies are needed to clarify whether SEMS placement increases the risk of perforation caused by bevacizumab-based therapies.

Abstract
INTRODUCTION Congenital cystic lesions of the lung in children are uncommon but potentially life-threatening and warrant an urgent diagnostic work-up. Pulmonary sequestration (PS), congenital cystic adenomatoid malformation (CCAM), congenital lobar emphysema (CLE), and bronchogenic cyst (BC) are the four major congenital cystic lesions, but they share similar embryologic and clinical characteristics. The purpose of this study is to review our institutional experience with congenital cystic lung disease emphasizing on diagnosis and management. PATIENTS AND METHODS Between January 1975 and October 2007, 109 patients have been treated, of which 57 males and 52 females, the age ranged from the birth to 13 years. 104 patients presented solitary lesions: CCAM (47), CLE (16), PS (22), BC (19). The remainders 5 patients presented two simultaneous lesions: intralobar PS and CCAM (2), CLE and CCAM (3). RESULTS All the lesions have been treated surgically: in the first cases, only symptomatic patients underwent surgery, while in the last years, patients have systematically been submitted operated. CONCLUSIONS A meaningful percentage of CCAM joins to PS and CLE; instead the BC are generally isolated, probably deriving by a more precocious embryogenetic defect. The treatment of these lesions is surgical: CCAM (type I-II) and CLE should be treated promptly in newborns for respiratory distress and pneumothorax; CCAM (type II) and BC generally become symptomatic gradually and expose to degenerative risk; intralobar PS generally becomes symptomatic and surgery prevents the risk of infections. Extralobar PS and the asymptomatic BC are not exempted by surgical approach whenever accidentally described as masses of uncertain nature. Asymptomatic cysts in children should be resected, to avoid later complications of the cysts, which could make operation more difficult. Conservative anatomic resections should be attempted to preserve functional lung tissue. Careful histologic examination of the resection specimen is mandatory to identify occult malignancy. In conclusion a correct embryogenetic organization and a clinical evaluation of the congenital cystic lung diseases allow a precocious and effective surgical timing.

Abstract
A 66-year-old woman was referred with left hearing loss. A probable diagnosis of left secretory otitis media with effusion was formulated. A left myringotomy was performed to remove hyperplastic hard tissue from the tympanic cavity. A high resolution CT scan of the temporal bone disclosed a soft-tissue mass completely involving the mastoid and tympanic cavity, surrounding the ossicular chain which appeared spared with no signs of infiltration. The histopathologic, immunohistochemical and ultrastructural response was secretory meningioma, a rare variant of conventional meningothelial meningioma in atypical sites.

Abstract
BACKGROUND The surgical treatment of biliary atresia is still a great challenge for pediatric surgeons. Kasai's operation usually needs a wide, painful, muscle-cutting laparotomies that quite often are followed by pain and peritoneal adhesion. These possible complications may disturb the post-operative course and humper liver transplantation. Advancements in minimally invasive surgery have allowed even the most complex procedures to be approached using these techniques. METHODS The authors present a case of successful Roux-en-Y laparoscopic portoenterostomy for the treatment of biliary atresia. We report a case of a 3-month-old patient with biliary atresia who weighted Kg 5,300 at the operation. The patient was placed in supine position. The procedure was performed with 4 trocars of 3 mm and 1 of 10 mm. The umbilical site was used for extracorporeal Roux-en-Y enteroenterostomy. CO2 was insufflated at a pressure of 8 mmHg and a flow of 0.5 L/min. A drain was placed through the lower trocar site with the tip near the anastomosis. RESULTS The procedure was free of neither intraoperative nor post-operative complications. Feeding by nasogastric tube was started after 2 days. Total oral feeding was possible after 8 days. CONCLUSION Laparoscopic approach to perform Kasai's operation is technically feasible and thanks to a magnified vision, it allows to abtain a good visualization of the portal structures with an adequate retraction of the liver. This procedure can avoid or decrease the post-operative complications such as pain, breathing difficulty, adhesions and resulting in very small scars. Anyway laparoscopic Kasaiportoenterostomy should be done by a surgeon with a good experience in laparoscopic hand-suturing and neonatal experience and with the support of an experienced in neonatal and infantile videosurgery anaesthesiologist.

Abstract
BACKGROUND Fetal and neonatal hepatic arteriovenous fistulas are rare and associated with a high mortality rate; they can be prenatally detected by ultrasonography. Management of these malformations can be a challenge for pediatric surgeons. METHODS Two patients with a prenatal diagnosis of intrahepatic arteriovenous shunts were treated at our institution in the last 2 years. A hepatic complex arteriovenous malformation fed respectively by prominent branches of the hepatic artery and of the celiac trunk rising from dilated suprarenal aortae and draining into suprahepatic veins was detected. In the first case, an embolization was performed; in the second, the surgical resection of the vascular malformation was the treatment of choice. RESULTS The first patient died after embolization and before surgery for hemodynamic complications. The second patient, at a follow-up of 16 months, is alive and doing well. CONCLUSION Hepatic resection is the treatment of choice for localized intrahepatic arteriovenous malformation. Theoretically, embolization could be curative or reduce the size of a malformation, making consequent hepatic resection feasible. Results do not support this theory because of the high rate of complications recorded that brought in every case, ours included, to the death of the child.

Abstract
A case report of acute, massive, prolonged hepatitis related to secondary syphilis in a patient with undiagnosed HIV infection is described together with possible pathogenetic mechanisms. This is a rare occurrence in resource-rich countries in the era of antibiotics. The impaired immune response and the dysregulation of the cytokine network may have played a role in mediating this severe expression of HIV-associated secondary syphilis. An apparently unexplained acute hepatitis should deserve accurate screening for sexually transmitted diseases, including syphilis and HIV infection.

Abstract
Solitary fibrous tumours are rare neoplasms, which occur most frequently during adulthood at the level of the pleura. Recently, these tumours have been demonstrated in extraserosal sites such as the nasal cavity. A case of a solitary fibrous tumour arising at the level of the ethmoid and presenting in a 54-year-old woman, is reported. The tumour was removed using an endonasal endoscopic approach that permitted the monobloc excision of the lesion. The patient is without evidence of disease 18 months after surgery.

Abstract
Anal cancer originates from a peculiar histological region and provides a useful model for investigating alterations in proliferation and/or differentiation of neoplastic keratinocytes. Epidermal differentiation complex (EDC) genes, which form one of the major gene clusters in the human genome, are involved in the terminal differentiation of epithelial cells and in many instances have been implicated in epithelial tumours. We constructed a DNA macroarray capable of characterising the expression profiles of the entire EDC gene complex in normal mucosa and anal cancer biopsies of seven unrelated patients. Brain tissue and cultured keratinocytes were used as controls. All anal cancer samples showed expression profiles in which none of the EDC genes was silent, as evaluated by phosphor-imager analysis. Variance analysis showed significantly lower expression of SPRR2 with respect to SPRR1 or SPRR3, and significantly higher expression of S100A8 than of other S100A subfamily members. At hierarchical clustering analysis, the four basaloid anal cancer cases conglomerated in the top five positions. The macroarray method used by us provides the first demonstration of the expression profile of the EDC gene family in anal cancer, and is capable of producing significant information on the subgrouping of epithelial tumours such as anal cancer.

Abstract
Five out of nine consecutive patients with HIV-related visceral aspergillosis observed by us since 1984 were diagnosed only at necropsy examination. The histopathological features of these five patients [two with isolated pneumonia, one with central nervous system (CNS) involvement, one with brain abscess and respiratory disease and one with pulmonary, pleural and kidney infection] have been evaluated according to epidemiological, clinical and radiological features. On the basis of our experience, life-threatening aspergillosis, which is often misdiagnosed or missed in the setting of HIV infection and AIDS, should be suspected in patients with far-advanced underlying disease and unexplained signs and symptoms, even in the absence of some presumed risk factors (i.e. neutropenia and prior steroid treatment). Plain chest radiography and bronchoscopy with broncholaveolar lavage may fail to reveal respiratory disease, CNS aspergillosis is not necessarily associated with suggestive neuroradiological features and disseminated disease may present with multiorgan failure. The unfavorable outcome of this emerging AIDS complication can be improved only by earlier diagnosis based on invasive techniques and appropriate and timely treatment.

Abstract
In a low-risk pregnant patient at 21 weeks' gestation, ultrasound revealed shortening of fetal long bones compatible with achondroplasia. Funipuncture was performed and DNA analysis of fetal blood demonstrated the presence of the GR380R fibroblast growth factor receptor 3 (FGFR3), which is specifically associated with achondroplasia. After termination of the pregnancy, necropsy confirmed the prenatal diagnosis. A certain sonographic diagnosis of fetal de novo achondroplasia is rarely possible prior to viability. The specificity of the FGFR3 causative mutation has added a new diagnostic option which can be applied prenatally for diagnostic validation.
