Abstract
Soft tissue sarcomas account for a small proportion of second cancers, with an estimated frequency of < 10%. The most common histologic type of soft tissue sarcomas as second cancers include mostly high-grade sarcomas, such as rhabdomyosarcoma, malignant peripheral nerve sheath tumour, fibrosarcoma, leiomyosarcoma, synovial sarcoma, alveolar soft part sarcoma and Ewing sarcoma/primitive neuroectodermal tumour (PNET). We report a case of superficial soft tissue Ewing sarcoma/PNET as a second cancer in a young patient previously treated for Hodgkin's disease (HD). To the best of our knowledge and based on a literature search, this is the first reported case of post-irradiation soft tissue Ewing sarcoma/PNET as a second cancer arising in the same area irradiated for cure of HD.

Abstract
This study reports on a case of an adult patient with embryonal rhadomyosarcoma of the prostate and comprehensively reviews the world literature on this subject. The patient was a 49-year-old man with advanced stage disease, who initially underwent transurethral tumor resection and after diagnosis was given courses of chemotherapy prior to undergoing radical cystoprostatevesiculectomy. The tumor underwent histological examination supplemented by immunohistochemical analysis. After surgery, the patient experienced a huge pelvic recurrence and eventually died of disease 1 year after the original diagnosis. The world literature was reviewed based both on a PubMed/Medline search and the reference lists of all the available publications on this subject and only 24 cases of primary embryonal prostatic rhabdomyosarcoma have been found in the world literature in adult males (≥18 years). Embryonal rhadomyosarcoma of the prostate in adults is a very rare and aggressive disease. The long-term disease-specific survival rate is poor. Stage influences the outcome. Early diagnosis and complete surgical resection offer patients the best chance of improved survival.

Abstract
Lipofuscin-like granules, first described by Biava and West in 1965, are a subcellular, quasi-physiologic finding mainly seen in the smooth muscle cells of renal arterioles, but also in juxtaglomerular cells and the lacis cells of human kidneys. They increase in number in subjects affected by arterial hypertension and diabetes. They do not correlate with a specific primary renal disease. Lipofuscin-like granules are not related to renin granules. The world literature on this subject is almost non-existent, and the awareness of this finding or its clinical significance among either pathologists or nephrologists is very poor. We incidentally observed these lipofuscin-like granules in 8 cases during the routine electron microscope examination of 440 renal biopsies, and report herein on their ultrastructural features. Six of these 8 patients were affected by arterial hypertension, one of whom was also concomitantly affected by diabetes mellitus. These lipofuscin-like granules appear as dense bodies with a lipid component, a coarsely granular matrix, and a crystalloid component which may appear in a band or dot pattern, according to the plane of sectioning. The pathologist has to be aware of these lipofuscin-like granules in order not to confuse them with the semicircularly organized (fingerprint) linear immune deposits associated with some specific glomerulopathies.

Abstract
The muscle or neuromuscular spindle is a proprioceptive microanatomic structure, which together with the Golgi tendon organ, is responsible for the reflex are that determines the tonic state of muscle. The Pacinian corpuscle (or corpuscle of Vater-Pacini) is a pure mechanoreceptor, sensitive to pressure, typically found in the skin, subcutis and superficial soft tissues. Generally, both the muscle spindle and Pacinian corpuscle are microanatomical findings that are too unremarkable to focus on during the course of routine work in surgical pathology. We recently encountered such a structure, which required full attention to be correctly identified: the incidental finding was a curious muscle spindle, the "fibrous capsule" of which mimicked the "lamellar body" of Pacinian corpuscle. This report accurately mirrors the manner in which the events occurred and emphasizes the fundamental anatomical notions that were ignored, and is also an opportunity to mention some of the pathological conditions affecting the aforementioned often-neglected receptors.

Abstract
Mutations in DNA double-strand breaks (DSB) repair genes are involved in the pathogenesis of hereditary mammary tumors, it is, however, still unclear whether defects in this pathway may play a role in sporadic breast cancer. In this study, we initially determined mRNA expression of 15 DSB related genes by reverse transcription quantitative polymerase chain reaction in paired normal tissue and cancer specimen from 20 breast cancer cases to classify them into homogeneous clusters. G22P1/ku70, ATR and RAD51 genes were differentially expressed in the three branches recognized by clustering analysis. In particular, a breast cancer subgroup characterized by high RAD51 mRNA levels and estrogen receptor (ER)-positive/progesteron receptor (PR)-negative phenotype was identified. This result was confirmed by the analysis of G22P1/ku70, ATR and RAD51 mRNA levels on paired normal and tumor specimens from an extended breast cancer cohort (n = 75). RAD51 mRNA levels were inversely associated with PR status (p = 0.02) and the highest levels were, indeed, detected in ER-positive/PR-negative tumors (p = 0.03). RAD51 immunostaining of a tissue microarray confirmed the inverse relationship between high RAD51 expression and negative PR status (p = 0.002), as well as, the association with ER-positive/PR-negative phenotype (p = 0.003). Interestingly, the analysis of microarray expression data from 295 breast cancers indicate that RAD51 increased mRNA expression is associated with higher risk of tumor relapse, distant metastases and worst overall survival (p = 0.015, p = 0.009 and p = 0.013 respectively). Our results suggest that RAD51 expression determination could contribute to a better molecular classification of mammary tumors and may represent a novel tool for evaluating postoperative adjuvant therapy for breast cancer patients.

Abstract
The objectives of this study were to evaluate the frequency of carcinoid tumors of the extrahepatic biliary ducts (EHBDs) and the pathologic progression and the role of surgery in the management of this disease. We describe two cases of malignant carcinoids of the EHBDs, which presented as common bile duct tumors in two adult male patients, aged 52 and 70 years, who were diagnosed histologically on surgical resection specimens. A comprehensive review of the literature has also been performed with a focus on survival data. Microscopically, the tumors presented herein were composed of relatively small rounded cells with a trabecular or nesting pattern. Both cases were diffusely immunopositive for chromogranin and synaptophysin, and one of them was also focally reactive with somatostatin and pancreatic polypeptide. There was no expression in any of these tumors of thyroid transcription factor-1 (TTF-1), gastrin, insulin, glucagon, vasoactive intestinal peptide (VIP) and prolactin. The tumor showed transmural invasion in both cases, with lymph node metastasis and subcapsular liver tissue infiltration in one. Both patients are alive with no evidence of disease 41 months and 59 months, respectively, after surgery. Despite being extremely uncommon, with only 70 cases reported to date, carcinoids should be included in the differential diagnosis of EHBD tumors. This study emphasizes the necessity of complete surgical resection as the gold standard treatment for these lesions, and the importance of a correct pathologic diagnosis for prognostic implications.

Abstract
We report a 50-year-old man who presented with a 5-year history of an intermittent widespread pruritic urticarioid rash and fever, fatigue, arthralgia and a monoclonal immunoglobulin-M paraprotein. The patient was initially treated with antihistamines and corticosteroids without the disappearance of symptoms. A skin biopsy from the urticarial rash on the thorax was performed, revealing dermal mononuclear and polymorphonuclear cell infiltrate and normal epidermis. A diagnosis of Schnitzler's syndrome (SS), a rare disorder in which the simultaneous occurrence of monoclonal gammopathy and chronic urticaria is usually observed, was made. After an unsuccessful trial with rituximab at a dosage of 375 mg/sqm weekly for 4 consecutive weeks, the patient was treated with anakinra, an inhibitor of interleukin-1alpha that is thought to be involved in the pathogenesis of the disease, at a dose of 100 mg daily given subcutaneously. He showed a prompt response to the drug and he is still well and symptom-free after 12 months of follow-up. On the basis of both this experience and the review of the literature we conclude that anakinra may be a promising option for the treatment of SS. However, these results need to be confirmed on a larger number of patients.

Abstract
Atypical and epithelioid cell variants of dermatofibroma may represent a potential diagnostic pitfall. Only rarely atypical dermatofibroma may show focal epithelioid cell features. We herein report a rare case of dermatofibroma composed of a predominant (> 90%) epithelioid/deciduoid-like cell component, in which rare multinucleated bizarre cells and atypical mitoses were additional findings. Tumour was classified as "atypical dermatofibroma with predominant epithelioid/deciduoid-like cell component". The coexistence of at least two different variants, i.e. epithelioid and atypical variants, in the same dermatofibroma suggests that dermal fibrohistiocytic tumours belong to a continuous morphological spectrum. Accordingly, the morphological variants of dermatofibroma should be regarded as variations on a common basic theme. Differential diagnosis with other epitheliod cell dermal tumour- and tumour-like lesions is discussed.

Abstract
Abstract
The maintaining of genome stability is one of the main mechanisms involved in prevention of tumor formation thus a number of intricate networks have evolved in eukaryotic cells to respond to exogenous and endogenous genotoxic stimuli. In an initial study we have analyzed mRNA expression changes of 15 genes involved in both Homologous Recombination (HR) and Non Homologous End Joining (NHEJ) pathways on paired normal and cancer tissues from 20 patients. Three genes, ATR, RAD51 and G22P1/Ku70 were differentially expressed in tumours as compared with normal tissues. To confirm data from the training set we analyzed by real-time quantitative PCR paired normal tissues and tumour specimens obtained from 55 breast cancer patients. Since high variability was found in normal tissues for each case we calculated the relative expression ratio (RER) in tumour samples as compared with normal tissue. When relative expression ratios were correlate with tumours clinical characteristics, only RAD51 showed higher RERs in the group of tumours with ER-positive/PR-negative phenotype as compared with the ER-positive/PR-positive and ER-positive/PR-negative subgroups (Kruskall-Wallis p=0.07). We used commercially available antisera to evaluate protein expression of RAD51 on a panel of 59 primary breast cancer and 3 fibroadenoma samples represented on a tissue microarray (BR641 Biomax.). RAD51 immunostaining was detected in 39 of the 58 (67%) breast cancers represented on a tissue microrray (median value 30%, range 0-70%). No staining was detected in the three fibroadenomas represented on the tissue microarray and in normal breast tissues represented in the tumor. When IHC results were compared with tumour clinicopathological characteristics, the percentage of RAD51 stained cells was higher in PR negative patients as compared with positive cases (P=0.002 Mann Whitney test) and this inverse correlation was confirmed in logistic regression analysis (P=0.0035). Interstingly all tumours ER-positive/PR-negative phenotype (12 out of 12) showed RAD51 immunostaining. Moreover, in this subgroup statistically significant higher levels of RAD51 protein were also detected as compared with ER-positive/PR-positive and ER-negative/PR-positive patients subgroups (Kruskall-Wallis p=0.004). In particular the analysis between groups demonstrated statistically significant differences between the ER-positive/PR-positive group and the ER-positive/PR-negative groups (Dunn Test P<0.01). Our data suggest an involvement of the RAD51 gene in the pathogenesis and progression of breast cancer and indicate that RAD51 overexpression may represent a specific feature of a subgroup of the Luminal subtype.

Abstract
Parathyroid carcinoma (PaC) is a rare cause of primary hyperparathyroidism. Though the loss of the oncosuppressor CDC73/HRPT2 gene product, parafibromin, has been involved in the hyperparathyroidism-jaw tumor syndrome and in a consistent set of sporadic PaCs, parathyroid carcinogenesis remains obscure. MicroRNAs are a new class of small, non-coding RNAs implicated in development of cancer, since their deregulation can induce aberrant expression of several target genes. The aim of the present study was to identify differentially expressed microRNAs in parathyroid cancers compared with normal tissues. We performed a TaqMan low-density array profiling of four parathyroid cancers harboring CDC73 inactivating mutations and negative for parafibromin immunostaining. Their microRNA profiling was compared with that of two normal parathyroid biopsies. Out of 362 human microRNAs assayed, 279 (77%) were successfully amplified. Fourteen and three microRNAs were significantly down- and over-expressed in parathyroid cancers respectively. Of these, miR-296 and miR-139 were down-regulated, and miR-503 and miR-222 were over-expressed with a null false discovery rate. Carcinomas could be discriminated from parathyroid adenomas by a computed score based on the expression levels of miR-296, miR-222, and miR-503 as miR-139 was similarly down-regulated in both cancers and adenomas. Finally, miR-296 and miR-222 levels negatively correlated with mRNA levels of the hepatocyte growth factor receptor-regulated tyrosine kinase substrate and p27/kip1 levels respectively. These results suggest the existence of an altered microRNA expression pattern in PaCs together with a potential role of miR-296 as novel oncosuppressor gene in these neoplasia.

Abstract
To fortify the biological role of milk formula has been suggested to use probiotics and prebiotics as functional components to mimic the effect of breast milk. The aim of this study was to evaluate the effects of prebiotic, probiotic added to a standard formula on gastrointestinal motility respect to placebo-formula. Cutaneous electrogastrography (EGG) and ultrasound gastric emptying (GE) were performed in 49 preterm newborns. 17 newborns were exclusively breast-fed; 32 were randomly assigned to receive prebiotic-added formula (0.8 g/dl of a mixture from scGOS and lcFOS, ratio 9:1) (10), a probiotic-added formula (L. reuteri at dose of 1x10(8) colony forming units (CFU) per day) (10), a formula with placebo (12) for 30 days. No difference was seen in the nutritional parameters and no adverse events were reported. After the intervention period, the prebiotic, probiotic, and breast milk groups showed a higher percentage of EGG slow wave propagation and faster gastric half emptying time respect to placebo group (ANOVAon ranks p<0.001; Dunn test vs control: prebiotic, probiotic and breast-milk vs placebo formula p<0.05; and ANOVA on ranks p=0.005; Dunn test vs control: prebiotic, probiotic and breast-milk vs placebo formula p<0.05, respectively). Feeding preterm infants with a formula supplemented with prebiotics or probiotics may stimulate gastric emptying and improve maturation of the EGG activity mimicking the effect of breast milk.

Abstract
BACKGROUND Breast milk oligosaccharides such as galacto-oligosaccharides (scGOS) and fructo-oligosaccharides (lcFOS) can influence the intestinal microbial flora. The latter, in turn, can modulate several intestinal and extraintestinal functions, including bilirubin metabolism. Supplementing infant formula with a prebiotic mixture might then be a novel and safe intervention to manage mild neonatal hyperbilirubinaemia. AIM To investigate the effect of dietary supplementation with prebiotics on moderate hyperbilirubinaemia in healthy, term infants. METHODS A prospective, double-blind, clinical trial was performed on seventy-six consecutive newborns who were randomly assigned to receive a formula containing 0.8 g/dL of a mixture from scGOS and lcFOS (ratio 9:1), or maltodextrines as placebo for 28 days. Bilirubin levels were determined by the transcutaneous bilirubin measurement within 2 h after birth (T1), at 24, 48 and 72 h and at 5, 7, 10 and 28 days of life. The number of stool per day was also recorded. RESULTS Neonates receiving prebiotics showed a larger number of stools over all the duration of dietary intervention compared to that of those on placebo (Repeated Measures ANOVA p < 0.001; day 28 3.4 +/- 0.0.9 vs 1.7 +/- 0.9, respectively; Dunn test p < 0.05). Neonates whose formula was supplemented with prebiotics showed a lower transcutaneous bilirubin that was statistically significant from 72 h of life (5.46 +/- 1.6 vs 7.07 +/- 2.49, post hoc Dunn test, p < 0.05) throughout the duration of the dietary intervention (day 28 2.41 +/- 0.4 vs 2.85 +/- 0.5, post hoc Dunn test, p < 0.05). CONCLUSION The addition of prebiotics to standard infant diet might represent a novel strategy to help control neonatal hyperbilirubinaemia.

Abstract
Aberrant promoter methylation of several known or putative tumor suppressor genes occurs frequently during carcinogenesis, and this epigenetic change has been considered as a potential molecular marker for cancer. We examined the methylation status of nine genes (APC, CDH1, CTNNB1, TIMP3, ESR1, GSTP1, MGMT, THBS1, and TMS1), by quantitative methylation specific PCR. Synchronous preinvasive lesions (atypical ductal hyperplasia and/or ductal carcinoma in situ) and invasive ductal breast carcinoma from 52 patients, together with pure lesions from 24 patients and 12 normal tissues paired to tumor and 20 normal breast distant from tumor were analyzed. Aberrant promoter methylation was detected in both preinvasive and invasive lesions for genes APC, CDH1, CTNNB1, TIMP3, ESR1, and GSTP1. However, hierarchical mixed model and Generalized Estimating Equations model analyses showed that only APC, CDH1, and CTNNB1 promoter regions showed a higher frequency and methylation levels in pathologic samples when compared with normal breast. Whereas APC and CTNNB1 did not show differences in methylation levels or frequencies, CDH1 showed higher methylation levels in invasive tumors as compared with preinvasive lesions (P < 0.04, Mann-Whitney test with permutation correction). The analysis of APC, CDH1, and CTNNB1 methylation status was able to distinguish between normal and pathologic samples with a sensitivity of 67% (95% confidence interval, 60-71%) and a specificity of 75% (95% confidence interval, 69-81%). Our data point to the direct involvement of APC, CDH1, and CTNNB1 promoter methylation in the early stages of breast cancer progression and suggest that they may represent a useful tool for the detection of tumor cells in clinical specimens.

Abstract
Four cases of hypereosinophilic syndrome (HES) treated with the tyrosine-kinase inhibitor imatinib-mesylate are reported. The drug was effective in three patients, but a prolonged clinical and hematological remission was obtained only in one patient, due to appearance of resistance or poor tolerability in the other cases. The dose of imatinib necessary to achieve a response ranged from 100 to 600 mg/d. One patient with evidence of a clonal T-cell population did not respond at all. We confirm the efficacy of imatinib in HES, but we also underline that type and duration of response may be variable. This could be due to different pathogenetic mechanisms of the disease in single patients.

Abstract
OBJECTIVE Optimal surgical management in lateral ventricle tumors remains controversial. We conducted a retrospective study of patients with these lesions treated with a surgical strategy on the basis of tumor origin: primary or secondary ventricular and associated transependymal development. METHODS A total of 72 patients underwent surgery for lateral ventricle tumors. The mean patient age was 39 years (range, 6 mo to 78 yr). Raised intracranial pressure occurred in 53% of patients, followed by mental disturbances or psychiatric symptoms (32%) and motor deficits (21%). The transcortical approach was used in 44 patients, and an interhemispheric approach was used in 28 patients; a transcallosal approach was used in 16 patients, and a parasplenial approach was used in 12 patients. Neuropsychological tests were performed in selected patients. RESULTS Total resection was performed in 82% of patients. Sixty-five percent of tumors were benign and low-grade tumors. There was no surgical mortality, and the morbidity rate was 11%. Postoperative epilepsy (5.9%) was significantly increased in the transcortical group. The mean follow-up period was 55 months; 59% of patients achieved good recovery and moderate disability. In postoperative neuropsychological testing sessions, deficits in verbal memory were observed in six patients (8%). Final morbidity correlated well with preoperative clinical condition and pathological diagnosis. CONCLUSION Lateral ventricle tumors can be treated best by careful selection of the approach according to tumor origin and development. Overall, the transcallosal approach is preferred, but in patients with transependymal growth or large primary or secondary ventricular tumors, the transcortical is a better option.
