Abstract
BACKGROUND/PURPOSE The purpose of the study is to describe the anatomoclinical, diagnostic, therapeutic and prognostic aspects of pediatric follicular thyroid carcinoma (FTC) in order to choose the best therapeutic strategy. METHODS Our study includes patients ≤18 years old surgically treated for FTC in four Italian Pediatric Surgery Centers from January 2000 to March 2017. The collected data were compared with those of 132 patients matched for age with a histological diagnosis of papillary thyroid carcinoma (PTC) surgically treated in the same institutions during the same period and with the data of patients diagnosed with FTC found in the literature; p-values <0.05 were considered significant. RESULTS 21 (70%) of the 30 patients with a histological diagnosis of FTC underwent hemithyroidectomy while 9 (30%) underwent total thyroidectomy. 11 (55%) out of 21 patients were subjected to a completion of thyroidectomy. All patients are alive (OS = 100%) without recurrence or relapse of the disease. Compared with PTC, FTC is significant for capsule infiltration (p < 0.0001), vascular invasion (p = 0.0014) and T-stage T3-T4 (p = 0.013). However, multifocality (p < 0.001), extrathyroid extension (p < 0.0001) and lymph node metastasis (p < 0.0001) are more evident in PTC. CONCLUSION The conservative approach seems to be a valid surgical treatment for pediatric patients diagnosed with MI-FTC. For patients with wide vascular invasion and/or a tumor >4 cm, especially with high after-surgery Tg rate, a completion of thyroidectomy is recommended. In patients with multifocal neoplasia, and/or tumor size ≥4 cm, and/or extrathyroid extension, and/or lymph node metastasis, and/or distant metastasis, total thyroidectomy followed by radioiodine therapy is generally indicated.

Abstract
PURPOSE This study was conducted to determine the difference in anatomo-pathological and prognostic features of cutaneous melanoma in children, adolescents and young adults. METHODS This is a retrospective review on 383 young patients ≤ 39 years of age with cutaneous melanoma, in a period from 2006 to 2016 in Area Vasta Nord Ovest, Tuscany, Italy. We subdivided patients in three groups (children ≤ 14 years, adolescents 15-21 years, young adults 22-39 years). We correlated all the anatomo-pathological parameters with age groups. RESULTS We identified a total of 426 cases of cutaneous melanoma on an overall total of 383 patients. Mean age at diagnosis for all the patients ≤ 39 years of age was 31.2 years: in group A was 11.2 years, in group B 19.2 years and in group C 32.5 years. Incidence, in the subjects between 0 and 14 years, is 14 cases per million inhabitants, between 15 and 21 years of 145, and between 22 and 39 years of 394. Global incidence was 1.6 case per million for group A, 8.9 cases per million for group B, 105 cases per million for group C. No statistically significative correlation could be described for clinical parameters and age groups. CONCLUSIONS Incidence of melanoma in our casuistry results as the highest in the world. These data open new study for this kind of cancer.

Abstract
In adolescents and young adults, thyroid cancer accounts for 13% of all invasive neoplasms, being three times more frequent in females, but overdiagnosis and overtreatment are common. There are two therapeutic approaches, one radical and no longer preferred in all instances, and the other conservative. Permanent complications of surgery and metabolic irradiation can affect quality of life and carry an economic burden. The overall survival rate approaches 100% for patients with differentiated thyroid cancer regardless of the extent of treatment. Medullary thyroid carcinoma is a very different entity, occurring most frequently in the context of hereditary tumor susceptibility syndromes.

Abstract
We have previously uncovered the impact of oncogenic and differentiation processes on extracellular vesicles (EVs) in cancer. This is of interested in the context of glioma stem cells (GSC) that are responsible for recurrent nature of glioblastoma multiforme (GBM), while retaining the potential to undergo differentiation and self renewal. GSCs reside in vascular niches where they interact with endothelial cells through a number of mediators including bioactive cargo of EVs. GSCs can be classified as proneural (PN) or mesenchymal (MES) subtypes on the basis of their gene expression profiles and distinct biological characteristics. In the present study we investigated how GSC diversity and differentiation programmes influence their EV-mediated communication potentials. Indeed, molecular subtypes of GBMs and GSCs differ with respect to their expression of EV-related genes (vesiculome) and GSCs with PN or MES phenotypes produce EVs with markedly different characteristics, marker profiles, proteomes and endothelial stimulating activities. For example, while EVs of PN GSC are largely devoid of exosomal markers their counterparts from MES GSCs express ample CD9, CD63 and CD81 tetraspanins. In both GSC subtypes serum-induced differentiation results in profound, but distinct changes of cellular phenotypes including the enhanced EV production, reconfiguration of their proteomes and the related functional pathways. Notably, the EV uptake was a function of both subtype and differentiation state of donor cells. Thus, while, EVs produced by differentiated MES GSCs were internalized less efficiently than those from undifferentiated cells they exhibited an increased stimulatory potential for human brain endothelial cells. Such stimulating activity was also observed for EVs derived from differentiated PN GSCs, despite their even weaker uptake by endothelial cells. These findings suggest that the role of EVs as biological mediators and biomarkers in GBM may depend on the molecular subtype and functional state of donor cancer cells, including cancer stem cells.

Abstract
VEGF is a specific mitogen and survival factor for endothelial cells and a key promoter of angiogenesis in physiological and pathological conditions. Nevertheless, VEGF tissue evaluation in cancer patients as a prognostic factor compared to the conventional histological and biological parameters is still controversial. In this case-control study, tissue VEGF was retrospectively determined by immunohistochemistry and related to T, N, ER, PgR, c-erbB-2, p53, MIB-1 and cyclin D1 in 129 breast cancer patients. Seventy-four of these patients had developed distant metastases postoperatively. The remaining 55 patients had remained disease-free >10 years after surgery. In 17 (13%) of the 129 patients (six with distant metastases and eleven disease-free) tissue and plasma VEGF were concomitantly evaluated. In univariate analysis no significant differences in VEGF and tumor size were found between metastatic and disease-free patients, whereas there were significant differences in N, ER, PgR, c-erbB-2, p53, MIB-1 and cyclin D1 (p ranging from 0.001 to 0.0001). In multivariate analysis VEGF showed less significance than N, ER, c-erbB-2, MIB-1 and cyclin D1 (p=0.012, p=0.007, p=0.005, p=0.005, p=0.002 and p=0.001, respectively). VEGF was a significant unfavorable prognostic indicator only in the N+ subset (p=0.015), while ER (p=0.05 and p=0.021) and MIB-1 (p=0.031 and p=0.022) were significant in both the N+ and N– subgroups. In multivariate analysis in the 74 metastatic cases VEGF did not show any significance in relation to disease-free interval and overall survival from the time of mastectomy and from the time of relapse, whereas N and PgR did (p ranging from 0.018 to 0.001). In conclusion, tissue VEGF does not seem a suitable candidate to replace conventional histological and other common biological prognostic factors in breast cancer.

Abstract
Krukenberg tumours are rare metastatic tumours of the ovaries characterized by the presence of mucin-producing neoplastic Signet Ring Cell Carcinoma (SRCC). At first glance, this tumour may be confused with a primary ovarian tumour. Surgery and chemotherapy combination have led to improvement in prognosis, but it still remains severe. We report the case of a 60-year-old woman with a Krukenberg tumour rising from a low differentiated gastric adenocarcinoma. The patient was clinically stable for 26 months after surgery until she experienced a prompt decline and died of cerebral haemorrhage within two weeks. The aim of this article was to give an overview of the Krukenberg tumour starting from our case report and comparing it with clinicopathological characteristics of this pathology derived from a review of recent literature.

Abstract
This study analyzes updated clinical, diagnostic, and surgical directions for the treatment of ovarian neoplasms in children and adolescents, comparing them with a retrospective analysis of 32 cases treated in two Pediatric Surgery University Institutions. From January 2005 to December 2015, 32 pediatric patients were surgically treated for 32 ovarian tumors: 28 (87.5%) benign and 4 (12.5%) malignant neoplastic lesions. Median age at surgery was 11.2 years (12.8 years in patients with benign neoplasms, 7.25 years in patients with malignant ones). All patients with malignant and 25% of patients with benign ovarian lesions had elevated serum level of tumors markers. The surgical approach was laparotomic in 62.5% and laparoscopic in 37.5%; 81.2% surgeries were performed in elective surgery and 18.8% in emergency. Intraoperative frozen section analysis was performed in 18.75% of patients. The most frequent surgery (96.8%) was unilateral oophorectomy. After a median follow-up of 76 months (range 6-132 months), 31/32 patients are alive and disease-free. In case of malignant tumors, fertility-sparing surgery with accurate staging must be performed. Laparoscopic multiport is the gold standard approach for benign pediatric ovarian neoplasms, but the use of laparoscopy in full respect of oncological principles also for early stage malignant tumors is currently increased.

Abstract
PURPOSE The extent of surgery for pediatric papillary thyroid carcinoma is debatable. The aim of this study was to evaluate the feasibility of offering pediatric patients a tailored surgical approach based on certain clinical features. METHODS A national multicenter retrospective review of 250 pediatric patients treated for papillary thyroid carcinoma in a 14-year period was performed. Outcomes of interest included tumor-related features, type of surgery, surgical morbidity, disease-free and overall survival rates. Recurrence was thoroughly analyzed with particular focus on how it correlated with certain patient- and tumor-related features. RESULTS The majority of patients (58.8 %) had tumors >2 cm in size. Nodal involvement occurred in 115/250 (46 %) patients and distant metastasis in 4 % (10/250). Total thyroidectomy and lobectomy were performed in 90.4 % (226/250) and 9.6 % (24/250) of patients, respectively. The overall rate of surgical complications was 20.8 % (52/250). These included transient and permanent hypoparathyroidism (13.6 and 4.4 %, respectively), and vocal fold palsy (2.8 %). All surgical complications occurred exclusively in the total thyroidectomy group. The rate of recurrent disease was 12 % (30/250) with the vast majority of recurrences (96.6 %) occurring in the total thyroidectomy group. The risk of recurrence correlated significantly with certain tumor-related features (size > 2 cm, multifocality, extrathyroidal invasion, nodal positivity, and distant metastasis). However, it did not correlate with the patient's age or sex. Overall survival was 100 %. CONCLUSION Pediatric patients are likely to benefit from a tailored surgical strategy. Uniformly offering patients total thyroidectomy seems to be an overly radical approach.

Abstract
BACKGROUND AND AIMS Branchial abnormalities occur when there is disturbance in the maturation of the branchial apparatus during fetal development. Branchial anomalies are congenital lesions usually present in childhood, even if they can be diagnosed later for enlargement or infection. A correct diagnosis will lead to proper management: complete surgical excision is the treatment of choice. The purpose of this article is to present clinical features, diagnostic methods and surgical treatment of branchial anomalies in childhood, based on a series of 50 patients. METHODS We conducted a retrospective analysis of a total of 50 pediatric patients operated from June 2005 to June 2014 for the presence of branchial cleft anomalies. RESULTS 27 cases (54 %) presented a second branchial cleft fistula and 11 cases (22 %) a second branchial cleft cyst and one case (2 %) presented both cyst and sinus of the second branchial cleft; four cases (8 %) presented first branchial cleft cyst whereas four cases (8 %) a first branchial cleft sinus and two cases (4 %) a first branchial cleft fistula; one case (2 %) presented a piriform sinus fistula (third branchial cleft). None of our patients presented anomalies of the fourth branchial cleft. All patients underwent surgical treatment and lesions have been removed by excision or fistulectomy. No post-surgical complication occurred. The rate of recurrence was 4 %. CONCLUSIONS Pre-operative diagnosis supplies important information to the surgeon for a proper therapy: a complete excision of the lesion without inflammatory signs is essential to avoid re-intervention and to achieve a good outcome.

Abstract
INTRODUCTION The aim of our study is to compare two different surgical procedures, lymphatic vessels and arterioles sparing microsurgical inguinal varicocelectomy (LASMIV) without delivery of the testis and LASMIV with delivery of the testis and ligature of collateral and gubernacular veins. MATERIALS AND METHODS Seventy adolescents suffering from varicocele and reduction of the ipsilateral testicular volume greater than 20% were prospectively assigned to two homogenous groups according to age and Tanner stage. The patients, operated from 2008 to 2013, were randomized to undergo either LASMIV without delivery of the testis or LASMIV with delivery and ligature of collateral and gubernacular veins. All patients were evaluated clinically and sonographically 6 months and 12 months after surgery, to measure testicular volume and to rule out any complications or recurrences. RESULTS The catch up growth of testicular volume is significantly higher at 6 (p value = 0.008) and 12 months (p value = 0.004) in patients treated with LASMIV with delivery. The rate of varicocele recurrence in patients who underwent the delivered maneuver is 0%, whereas is 2.8% without delivery; however this findings is not statistically significant (p value > 0.01). None of the patients of both groups presented secondary hydrocele. CONCLUSIONS LASMIV with delivery of the testis and ligature of all collateral and gubernaculuar veins results in significantly higher left testicular catch up growth.

Abstract
Thyroid tumors affect all age groups, including children and adolescents. Malignant cancer of the thyroid is a relatively uncommon disease in pediatric age. In the recent decades the incidence of paediatric differentiated thyroid carcinoma (DTC) has increased. DTC in paediatric age is rare and has an excellent prognosis. Compared to adult counterpart, DTC in childhood presents some different features as follows: larger volume at the diagnosis, more frequent multicentricity (both mono- and bilateral), earlier local involvement of soft tissue of the neck, earlier lymph node involvement, distant metastases 3-4 times more frequent (most often in the lungs and almost always functional) and more common post-operatory recurrence; nevertheless, the prognosis of DTC in childhood is better and the survival greater than in adult. Because of unusual association between aggressive presentation and good prognosis, the choice about the surgical treatment to perform in DTC is debatable, especially between conservative and radical approach in TNM stage I pediatric patients. To date, total thyroidectomy is the operation most often performed in children with DTC, although recently conservative surgery has been performed in solitary unifocal nodule without evidence distant metastases.

Abstract
Medullary thyroid carcinoma (MTC) is a rare, accounting for 5% of thyroid malignancies. It is a neuroendocrine tumor wich origins from thyroid parafollicular cells. It may be sporadic, mostly in adult patients, or inherited as autosomal dominant pattern, mostly in pediatric patients. As familial cancer, MTC may presented isolated as familial medullary thyroid carcinoma (FMTC) - 10% of cases - or, most often, as part of multiple endocrine neoplasm type 2 (MEN 2A or MEN 2B) syndromes - 90% of cases. The therapy for sporadic or hereditary MTC is surgical resection and consists in total thyroidectomy associated with central compartment lymph nodal dissection; the radicality of this intervention is fundamental to obtain a definitive cure. Genetic screening in children of parents with MEN2 or FMTC has led to prophylactic total thyroidectomy. The type of prophylactic surgery required is focus of great attention, and it is reported that total thyroidectomy, central neck dissection associated with parathyroid autotransplantation is the proper management. In children, the recommended age of surgery based on genetic testing is 5 years for patients with MEN 2A and FMTC, and 1 year for children possessing the RET mutation responsible for MEN 2B. The surgical management changes depending on the type of codon mutated.

Abstract
Breast cancer occurs rarely in male patient. BRCA1 gene mutation seems to be related to male breast cancer, but its role is not clearly defined. We have identified in a male patient affected by breast cancer the BRCA1 gene variant p.P142H. We performed a literature research using the keywords "male breast cancer", "male breast cancer mutations" and "BRCA" and we reviewed the cases. We found ew other studies regarding BRCA1 variant p.P142H, about female subjects. At the moment, BRCA1 gene variant p.P142H is not certainly classified as neutral or deleterious. Genetic testing for BRCA1 and BRCA2 and PALB2 mutation gene has been performed on our patient. Segregation analysis for this p.P142H BRCA1 variant has been extended to the second generation of the family. Genetic tests revealed a clear inheritance regarding the BRCA1 gene p. P142H variant. Of the eight patients with this specific genetic mutation, four presented breast cancer (bilateral in one case), two female and two male. None of the subjects in the family without the BRCA1 gene variant p. P142H presented breast cancer or other BRCA1 gene mutation-related cancers. Our analysis suggests that the BRCA1 gene variant p.P142H mutation is related with male breast cancer. Starting from these data, it can be inferred that more studies on MBC and its relation with the BRCA1 gene mutation P142H variant must be undertaken to improve prognostic and therapeutic strategies.

Abstract
BACKGROUND AND AIMS Ganglioneuromas are benign tumors which originate from the neural crest. This tumor affects mainly young patients rather than adult ones, and its most frequent localizations are mediastinum, retroperitoneum, adrenal glands and cervical region. Usually, ganglioneuromas are discovered as incidentalomas since they are often asymptomatic, even if they could present sympathetic or mass-related symptoms. To obtain a definitive diagnosis, histological exam is necessary since CT scan and MRI are not capable of distinguishing ganglioneuromas from other tumors, such as neuroblastomas or pheocromocytomas. The surgical excision is the chosen treatment and it offers an excellent prognosis. METHODS We conducted a retrospective analysis of our cases of ganglioneuroma from 2004 to 2014; this study aims to compare our experience with literature review (2000-2014). Data about patients' features, tumor localization, symptoms, treatment and follow-up were analyzed and reported in detailed tables. RESULTS Between 2004 and 2014 we treated 14 patients affected by ganglioneuroma. For all of them the diagnosis was incidental; 9 out of 12 (64.3 %) patients presented an adrenal mass; in 2 patients (14.3 %) the tumor was localized in cervical region; in other 2 patients (14.3 %) the tumor was in the retroperitoneum and one patient (7.1 %) presented a ganglioneuroma in the costo-vertebral space. All our patients underwent surgical removal and none of them present surgery-related complications or recurrences to date. CONCLUSIONS Our data widen the knowledge about ganglioneuroma and confirm that the surgical approach has an excellent prognosis with very low incidence of surgery-related complications and recurrences.

Abstract
In this study, we analyze the management of ovarian masses in a total of 130 children surgically treated for 137 ovarian lesions (7 bilateral). The most frequent symptoms were chronic (52.3%) and acute (25.4%) abdominal pain. Histological examination revealed 64 (46.7%) functional lesions, 59 (43.1%) benign neoplasms, 5 (3.7%) malignant ones, and 7 (6.6%) torsed normal ovaries. Ovarian torsion occurred in 36 cases (26.27%). A conservative treatment was performed in 81 (59.1%) girls: 61 (75.3%) treated in nonemergency and 20 (24.7%) in emergency surgery; laparoscopic approach in 35 cases (43.2%); and open surgery in 46 (56.8%). The remaining 56 (40.9%) ovarian masses underwent nonconservative surgery: 40 cases (71.4%) nonemergency and 16 (28.6%) emergency; laparoscopy in 20 patients (35.7%); and open surgery in 36 (64.3%). Fertility preservation should be a goal in the surgical treatment. The management of ovarian torsion should include adnexal detorsion and recovery of the ovarian tissue. In case of benign neoplasms, laparoscopic tumorectomy should be the gold standard; in early stage malignant tumors, fertility-sparing surgery with accurate staging is preferred.

Abstract
PURPOSE The aim of this study was to investigate the effects of gonadotropin releasing hormone analog (GnRHa) therapy on normalized testicular atrophy index (TAIn) using gonadorelin before and after orchiopexy. METHODS 62 infants with 87 undescended testes (UDT) were prospectively assigned to two homogeneous groups according to age, position of UDT and TAIn. The patients were randomized to receive either orchiopexy alone or orchiopexy combined with GnRHa as nasal spray at 1.2 mg daily for 4 weeks before surgery and 4 weeks after surgery. Surgical approaches were relative to the position of the UDT: Shoemakers technique in proximal-UDT and Bianchi technique in distal-UDT. All the patients were evaluated clinically and sonographically 1 month before surgery, at the time of surgery, 1 month, 6 months and 5 years after surgery. RESULTS Ultrasound data in our study have shown a statistically significant decrease of TAIn in children given additional HT only after 5 years of follow-up, in unilateral cases and in the entirety of treated patients; in bilateral cases this difference was not statistically significant. CONCLUSION Patients with a TAIn >20% treated with preoperative and post-operative GnRHa therapy have a significant increase in testicular volume after 5 years of follow-up, as shown by the relative reduction of TAIn values.

Abstract
BACKGROUND Minimally invasive video-assisted thyroidectomy (MIVAT) proved to be safe and effective in the treatment of both benign and malignant disease. The aim of the present study is to compare MIVAT approach with conventional approach for total thyroidectomy in a group of 99 pediatric patients operated in the Department of General Surgery of the University of Pisa between March 2007 and July 2012. PATIENTS A total of 99 pediatric patients under the age of 18 years with thyroid disease referred to our Department to undergo total thyroidectomy. Patients were divided into two groups according to the surgical technique performed: 34/99 (34.3%) patients (MIVAT group [MG]) and 65/99 (65.7%) patients, (conventional group [CG]) who underwent total thyroidectomy, respectively, with MIVAT approach and conventional approach. RESULTS In MG mean operative time for total thyroidectomy was 40 ± 6.57 minutes (range 30-60 min); postoperative hospital stay was 1 day for 18 patients (53%), 2 days for 12 patients (35.25%), 3 days for 4 patients (11.8%); transient hypoparathyroidism (hypoPTH) was observed in 12 cases (35.3%) and permanent hypoPTH in 2 cases (5.9%); transient postoperative unilateral vocal cord palsy was observed in 2 patients (5.9%). In CG mean operative time for total thyroidectomy was 49.3 ± 12.9 minutes (range 30-80 min); postoperative hospital stay was 1 day for 16 patients (24.6%), 2 days for 40 patients (61.5%), 3 days for 8 patients (12.3%), and 4 days for 1 patient (1.6%); transient hypoPTH was observed in 23 cases (35.4%) and permanent hypoPTH in 4 cases (6.1%), who needed therapy with calcitriol and calcium carbonate; transient postoperative unilateral vocal cord palsy was observed in 4 patients (6.1%). There were no cases of permanent vocal cord paralysis in both groups. The correlation between two groups of patients showed that mean operative time was significantly lower in MG (p = 0.0007). CONCLUSION Pediatric patients of MG showed a significantly lower operative time and postoperative hospital stay with respect to pediatric patients of CG if compared with conventional technique. This result with the evidence of similar degree of completeness and rate of postoperative complications make MIVAT a valid option for the treatment of pediatric patients when performed by a well-trained staff in a third referral center.

Abstract
CONTEXT AND OBJECTIVE We have studied the antitumor activity of a pyrazolo[3,4-d]pyrimidine compound (CLM3) proposed for a multiple signal transduction inhibition [including the RET tyrosine kinase, epidermal growth factor receptor, and vascular endothelial growth factor (VEGF) receptor and with antiangiogenic activity] in primary anaplastic thyroid cancer (ATC) cells, in the human cell line 8305C (undifferentiated thyroid cancer), and in an ATC-cell line (AF). DESIGN AND MAIN OUTCOME MEASURES CLM3 was tested in primary ATC cells at the concentrations of 5, 10, 30, and 50 μM; in 8305C cells, in AF cells, at 1, 5, 10, 30, 50, or 100 μM; and in AF cells in CD nu/nu mice. RESULTS CLM3 significantly inhibited the proliferation of 8305C and AF cells, also inducing apoptosis. A significant reduction of proliferation with CLM3 in ATC cells (P < .01, ANOVA) was shown. CLM3 increased the percentage of apoptotic ATC cells dose dependently (P < .001, ANOVA) and inhibited migration (P < .01) and invasion (P < .001). The AF cell line was injected sc in CD nu/nu mice, and tumor masses became detectable 15 days later. CLM3 (50 mg/kg per die) significantly inhibited tumor growth (starting 16 d after the beginning of treatment). CLM3 significantly decreased the VEGF-A expression and microvessel density in AF tumor tissues. Furthermore, CLM3 inhibited epidermal growth factor receptor, AKT, and ERK1/2 phosphorylation and down-regulated cyclin D1 in 8305C and AF cells. CONCLUSIONS The antitumor and antiangiogenic activity of a pyrazolo[3,4-d]pyrimidine compound (CLM3) is very promising in anaplastic thyroid cancer, opening the way to a future clinical evaluation.

Abstract
Spigelian hernia (SH) is a surgical rarity in children, which occurs through slit-like defects in the anterior abdominal wall adjacent to the semilunar line, the convexity lateral line which joins the nine ribs to the pubic tubercle and signs the limit between the muscular and aponeurotic portion of transversus abdominis muscle. As there are no specific symptoms and signs, the diagnosis is difficult, especially in children. We report a case of SH that comes to our observation: a 14-year-old girl presented recurrent abdominal pain associated to intermittent palpable mass in the paraumbilical region. Starting from our case report, we review the literature of pediatric SH from 2000 to 2013 and we describe the anatomy, etiology, clinical presentation, instrumental diagnosis, and surgical technique of pediatric SH.

Abstract
Primary retroperitoneal müllerian adenocarcinoma (PRMA) is an extremely rare clinical entity. We report the case of a 54-year-old woman who presented with a mass in the right lower retroperitoneum, identified during an ultrasound exam. Computed tomography confirmed a retroperitoneal mass measuring 11 cm. The patient underwent laparotomy and the mass was completely excised. The histopathological exam revealed PRMA.

Abstract
More than a million people a year worldwide develops colorectal cancer (CRC), with a mortality rate close to 33%. Most of the CRC cases are sporadic, only 25% of the patients have a family history of the disease, and major genes causing syndromes predisposing to CRC only account for 5-6% of the total cases. The following subtypes can be recognized: MIN (microsatellite instability), CIN (chromosomal instability), and CIMP (CpG island methylator phenotype). CRC arises from an accumulation of genetic and epigenetic alterations such as DNA methylation, which is able to modulate gene expression. Several studies in the literature show a possible correlation between an altered methylation in the promoter of tumor suppressor genes, proto-oncogenes, genes involved in DNA repair and the CRC risk; it has also been observed a global DNA hypomethylation, especially in the presence of a low folate uptake. Epigenetic changes are reversible, then could be interesting to evaluate on their relationship with dietary factors (as well as folates) and the genetic background of the individuals, for the development of novel strategies for cancer prevention.

Abstract
The purpose of this study is to discuss the surgical treatment for ovarian torsion in children and adolescents with a focus on the procedures of adnexal conservation surgery and its frequency in the literature of the last 10 years. We retrospectively reviewed the medical charts of 127 operative ovarian lesions including 30 ovarian torsions (23.6%) treated in two pediatric centers over a 10-year period. Age at presentation, presenting symptoms, diagnostic studies, surgical procedure and pathological findings were analyzed. Mean age was 13.7 years. Conservative surgery has been performed in 46.7% of the cases and laparoscopic approach in 40%. Ovarian torsion occurred in 56.7% on ovaries with functional lesion, in 23.3% on normal adnexa and in 20% on ovaries with benign neoplasm. The article includes a literature review (2000-2010) and a statistical analysis which shows a slow increase in conservative surgery from 28 to 45%. Laparoscopic surgery accounts for 23.5%. Literature review shows 40.5% normal adnexa, 33.2% non-neoplastic lesions, 25.3% benign neoplasms and 1% malignant neoplasms. The surgical treatment of children and adolescents presenting adnexal torsion should be practiced as an emergency and it should be more conservative as possible in order to maximize the future reproductive potential.

Abstract
BACKGROUND Standard imaging methods in evaluating chest wall deformities, such as Pectus Excavatum (PE) in paediatric and adolescent patients, include baseline 2-view chest radiography and chest CT scan. Only few studies to date investigated the value of fast MRIin the pre operative assessment of patient affected by PE. OBJECTIVE To evaluate the efficacy of chest fast MRI in pre-operative management of patient affected by PE. To obtain the Haller Index (HI) and Asymmetry Index (AI) from chest fast MRI protecting patients from radiation exposure. MATERIALS AND METHODS We analyzed the data of 42 consecutive patients with severe PE who underwent minimally invasive repair between March 2007 and March 2010. All 42 patients received chest fast MRI, but only the first 5 in view of the results, were studied also with chest ultrafast CT scan. In both examinations, data at the deepest point of the depression were collected. RESULTS Severity indices of the deformity using HI and AI, collected from CT scan and fast MRI in the first 5 patients, were comparable. In the remaining 37 fast chest MRI offered good images of the chest wall deformities with no radiation exposure, detailing anatomical information such as displacement and rotation of the heart or great vessels anomalies. CONCLUSION This study suggests the use of chest MRI in pre operative workup for patients with PE to obtain severity indices (Haller Index and Asymmetry Index avoiding radiation exposure to paediatric patients.
