Abstract
The hypermethylation status of the promoter region of the breast cancer 1 (BRCA1), a well-known tumor suppressor gene, has been extensively investigated in the last two decades as a potential biomarker for breast cancer. In this retrospective study, we investigated the prevalence of BRCA1 promoter methylation in 84 human breast tissues, and we correlated this epigenetic silencing with the clinical and histopathological parameters of breast cancer. We used methylation-specific PCR (MSP) to analyze BRCA1 promoter hypermethylation in 48 malignant breast tumors (MBTs), 15 normal adjacent tissues (NATs), and 21 benign breast lesions (BBLs). The results showed that BRCA1 promoter hypermethylation was higher in MBTs (20/48; 41.67%) and NATs (7/15; 46.67%) compared to BBLs (4/21; 19.05%). The high percentage of BRCA1 hypermethylation in the histologically normal adjacent tissues to the tumors (NATs) suggests the involvement of this epigenetic silencing as a potential biomarker of the early genomic instability in NATs surrounding the tumors. The detection of BRCA1 promoter hypermethylation in BBLs reinforces this suggestion, knowing that a non-negligible rate of benign breast lesions was reported to evolve into cancer. Moreover, our results indicated that the BRCA1 promoter hypermethylated group of MBTs exhibited higher rates of aggressive features, as indicated by the SBR III grade (14/19; 73.68%), elevated Ki67 levels (13/16; 81.25%), and Her2 receptor overexpression (5/20; 25%). Finally, we observed a concordance (60%) in BRCA1 promoter hypermethylation status between malignant breast tumors and their paired histologically normal adjacent tissues. This study highlights the role of BRCA1 promoter hypermethylation as a potential useful biomarker of aggressiveness in MBTs and as an early marker of genomic instability in both histological NATs and BBLs.

Abstract
Autism Spectrum Disorder is a neurodevelopmental disorder characterized by impaired social and communication skills, repetitive behaviors, and/or restricted interests with a prevalence of as high as 1% of children. Autism spectrum has strongly associated with genetic factors and exhibits wide clinical and heterogeneous genetic architecture. Most genes associated with Autism are involved in neuronal and synaptic development. The neuroligin3, the sex-linked gene on the X chromosome, was the first gene to be associated with a monogenic form of Autism. Neuroligin3 is a postsynaptic cell adhesion protein involved in synapse transmission, brain formation, and neuronal development. In this review, we provide recent findings on different mutations in the Neuroligin3 gene linked to Autism spectrum disorder and their molecular pathway effect. We also give the behavioral, and synaptic alterations reported in the Neuroligin3 animal model of Autism and the potential therapeutic strategies targeting the biological processes and the main symptoms of autism spectrum disorder. In addition, we discuss the use of novel technologies like induced pluripotent stem cells from Autistic patients that have the potential to differentiate in human neurons and therefore have a variety of applications in therapy and biomedical studies to search specific biomarkers, and develop systems for screening chemical molecules in human cells to discover target therapies.

Abstract
The comparative analysis of the expression of the reactive oxygen species-generating NADPH oxidase NOX4 from TCGA data shows that the NOX4 transcript is upregulated in papillary thyroid carcinomas (PTC)-BRAFV600E tumors compared to PTC-BRAFwt tumors. However, a comparative analysis of NOX4 at the protein level in malignant and non-malignant tumors is missing. We explored NOX4 protein expression by immunohistochemistry staining in malignant tumors (28 classical forms of PTC (C-PTC), 17 follicular variants of PTC (F-PTC), and three anaplastic thyroid carcinomas (ATCs)) and in non-malignant tumors (six lymphocytic thyroiditis, four Graves' disease, ten goiters, and 20 hyperplasias). We detected the BRAFV600E mutation by Sanger sequencing and digital droplet PCR. The results show that NOX4 was found to be higher (score ≥ 2) in C-PTC (92.9%) compared to F-PTC (52.9%) and ATC (33.3%) concerning malignant tumors. Interestingly, all C-PTC-BRAFV600E expressed a high score for NOX4 at the protein level, strengthening the positive correlation between the BRAFV600E mutation and NOX4 expression. In addition, independent of the mutational status of BRAF, we observed that 90% of C-PTC infiltrating tumors showed high NOX4 expression, suggesting that NOX4 may be considered a complementary biomarker in PTC aggressiveness. Interestingly, NOX4 was highly expressed in non-malignant thyroid diseases with different subcellular localizations.

Abstract
Vascular endothelial growth factor (VEGF) and its receptors (VEGFR1 and VEGFR2) are the most important tissue factors involved in tumor growth and angiogenesis. The aim of this study was to evaluate the promoter mutational status of VEGFA and the expression levels of VEGFA, VEGFR1, and VEGFR2 in bladder cancer (BC) tissues and to correlate the results with the clinical-pathological parameters of BC patients. A total of 70 BC patients were recruited at the Urology Department of the Mohammed V Military Training Hospital in Rabat, Morocco. Sanger sequencing was performed to investigate the mutational status of VEGFA, and RT-QPCR was used to evaluate the expression levels of VEGFA, VEGFR1, and VEGFR2. Sequencing of the VEGFA gene promoter revealed the presence of -460T/C, -2578C/A, and -2549I/D polymorphisms, and statistical analyses showed a significant correlation between -460T/C SNP and smoking (p = 0.02). VEGFA and VEGFR2 expressions were significantly up-regulated in patients with NMIBC (p = 0.003) and MIBC (p = 0.03), respectively. Kaplan-Meier analyses showed that patients with high VEGFA expression had significantly longer disease-free survival (p = 0.014) and overall survival (p = 0.009). This study was very informative, showing the implication of VEGF alterations in BC, suggesting that VEGFA and VEGFR2 expressions could be promising biomarkers for the better management of BC.

Abstract
Abstract
Background
The main epigenetic event occurring during the bladder carcinogenesis process is DNA methylation, affecting genes involved in various metabolic pathways and cell regulation. The use of biological fluids such as urine sediments could be used as a non-invasive approach to enhance bladder cancer management. In this study, we aim to determine the promoter methylation status of a panel of genes in bladder cancer on tumor biopsies and urine sediments to evaluate the usefulness of urine samples as a non-invasive approach for methylation status assessment.
Methods
Using the methylation-specific PCR technique, we explored the promoter methylation status of hTERT, TWIST1, VIM and NID2 genes in 40 tumor biopsies and their paired urine samples from Moroccan bladder cancer patients.
Results
In this study, bladder tumors showed promoter hypermethylation frequency of individual genes as 90%, 85%, 62.5% and 72.5% in TWIST1, hTERT, NID2 and VIM genes, respectively.
Interestingly, the specificity of methylation detection in urine samples was 100% and the sensitivity to detect hypermethylation of TWIST1, hTERT, NID2 and VIM genes reached 91.7%; 97.1%; 84% and 82.8%, respectively.
Conclusions
Our results clearly show that the assessment of promoter hypermethylation in urine samples is highly specific and has high sensitivity. Furthermore, urine sediments would be a useful approach to detect the DNA methylation status of genes and its potential association with bladder cancer development.

Abstract
BACKGROUND Mutations in RAS (KRAS, NRAS) and BRAF genes are the main biomarker predicting response to anti-EGFR monoclonal antibodies in targeted therapy in colorectal cancer (CRC). OBJECTIVE Our study aims to evaluate the frequencies of KRAS, NRAS and BRAF mutations and their possible associations with clinico-pathological features in CRC patients from Morocco. METHODS DNA was extracted from 80 FFPE samples using the QIAamp DNA FFPE-kit. RAS and BRAF mutations were assessed by pyrosequencing assays using Qiagen, KRAS Pyro®kit 24.V1, Ras-Extension Pyro®kit 24.V1 and BRAF Pyro®Kit 24.V1, respectively, and carried out in the PyroMark-Q24. RESULTS RAS mutations were identified in 57.5% (56.2% in KRAS, 8.8% in NRAS). In KRAS gene, exon 2 mutations accounted for 93.3% (68.9% in codon 12, 24.4% in codon 13). Within codon 12, G12D was the most prevalent mutation (37.7%), followed by G12C (13.4%), G12S (8.9%) and G12V (6.6%). Within codon 13, the most frequently observed mutation was G13D (22.3%). The mutation rates of exon 3 and 4 were 15.6% and 13.3%, respectively. In exon 3 codon 61, 2.3% patients were detected with two concurrent mutations (Q61R, Q61H), and 4.4% with three concurrent mutations (Q61R, Q61H, Q61L). In NRAS gene, the mutation rates of exon 2, 3 and 4 were 57.1%, 28.6%, and 14.3%, respectively. G13A and Q61H were the most common mutations, accounting for 42.9% and 28.5%, respectively. There were 13% patients with concurrent KRAS/NRAS mutation and 4.3% wt KRAS with NRAS mutations. No mutations were identified in BRAF gene. In both sexes, KRAS codon 12 mutations were associated with higher stage III/IV tumors. Moreover, Patients whose tumor is in the proximal colon (56.3%) are more likely to harbor KRAS mutations than those tumor located in rectum (25%). CONCLUSION RAS mutations could be useful in future target anti-EGFR therapy and molecular CRC screening strategy in Morocco.

Abstract
Abstract
Dermal nonneural granular cell tumor is a rare neoplasm of uncertain histogenesis that Le Boit and colleagues originally described in 1991. It arises commonly from the back, extremities and head and neck. To the best of our knowledge, only 50 cases have been reported in adults in the English literature. A 42-year-old man presented with a polypoid skin nodule of the front side of the chest wall, measuring 1,8 × 1,5 cm. The lesion was removed completely with tumor-free margins. Microscopically, the tumor was composed of a diffuse infiltrate of polygonal cells, S 100 negatives, with abundant granular cytoplasm and vesicular nuclei. The diagnosis of dermal nonneural granular cell tumor was retained. No recurrence was noted during follow up of 6 months. The prognosis is good.

Abstract
Teratocarcinosarcoma is a rare and aggressive malignant tumor of uncertain histogenesis. It presents <1% of all cancers and ~3% of malignant tumors of the head and neck. It arises commonly from the nasal cavity and paranasal sinuses. To the best of our knowledge, only one case has been reported in the oral cavity. A 46-year-old woman presented with 3-week history of a rapidly growing tumor in the inner side of the left cheek. Physical examination revealed an ulcerating mass measuring 4 × 3.5 cm. An excisional biopsy was performed. Histological analysis revealed a teratocarcinosrcoma. The patient was treated by combined chemotherapy and radiation therapy. No recurrence was noted 6 months after treatment. The prognosis is poor.

Abstract
Introduction in cancer cells, activating mutations in PIK3CA and AKT1 genes, major players of PI3K-AKT-mTOR signalling pathway, are widely reported in many cancers and present attractive targets for the identification of new therapeutics and better cancer management. The present study was planned to evaluate the mutational status of PIK3CA and AKT1 genes in bladder cancer patients and to assess the association between these mutations and patients´ clinico-pathological features. Methods in this prospective study, bladder cancer biopsies and matched urine sediments samples were collected form 70 patients. Mutations were assessed by deoxyribonucleic acid (DNA) sequencing and correlation with clinico-pathological data was performed using SPSS software. Results AKT1 alterations were poorly detected. Only one patient with pT1 stage and high-grade tumour carried the E17K mutation. In PIK3CA exon 9, 2 point mutations, E545K and Q546E, and a SNP (E547E) were reported, whereas in exon 20, 2 point mutations (L989V and H1047R) and 2 SNPs (I1022I and T1025T) were detected. PIK3CA mutations were mainly observed in early stages and high-grade tumours. Statistical analysis showed no significant association between the studied AKT1 and PIK3CA mutations and patients´ clinico-pathological parameters (p > 0.05). Detection of these mutations in voided urine samples showed a high specificity (100%) for both genes and a moderate sensitivity: 100% for AKT1 and 66.7% for PIK3CA genes. Conclusion this study shows clearly that mutations in AKT1 and PIK3CA are rare events and could not be considered as valuable biomarkers for bladder cancer management.

Abstract
Background Tumor recurrence and progression in non-muscle invasive bladder cancer (NMIBC), therapy failure, and severe side effects in muscle invasive bladder cancer (MIBC) are the major challenges in the clinical management of bladder cancer (BC). Here, we identify new molecular targetable signatures to improve BC patients’ stratification and the outcome of current immunotherapies. Material and Methods In a prospective cohort of 70 BC patients, we assessed the genetic and molecular regulation of TERT in maintaining telomere length in parallel to immune checkpoint and microRNA expression. Results TERT was undetectable in healthy bladder tissues but upregulated in invasive BC stages and high tumor grade. Its expression was linked with the combined effect of the C250T mutation and THOR hypermethylation, associated with progressing tumors and maintaining of telomere length. In the same cohort, PD-L1 scored highest in NMIBC, while PD-L2 was upregulated in MIBC. We also show that miR-100-5p and 138-5p were highly expressed in healthy bladder specimens and cell line, while expression decreased in the BC tissues and BC cell lines. In line with the binding prediction for these miRNAs on target genes, miRs 100-5p and 138-5p expression strongly inverse correlated with TERT, PD-L1, and PD-L2 expression, but not PD1. Conclusion We identify a loop involving TERT, PD1-ligands, and miR-138-5p in BC, that might represent not only a useful biomarker for improved diagnosis and patients’ stratification but also as a promising axis that might be therapeutically targeted in situ.

Abstract
Promoter hypermethylation have been reported to play a key role in bladder cancer development and progression. The aim of this study is to evaluate the methylation status of hTERT, TWIST1, VIM and NID2 genes in bladder cancer. The methylation status was evaluated using the Methylation-Specific PCR (MSP) approach on 70 tumour biopsies from Moroccan bladder cancer patients. Overall, methylation frequencies of hTERT, TWIST1, VIM and NID2 genes, were 90%, 85.71%, 67.14% and 67.14%, respectively. Hypermethylation of all studied genes was found in all pathological grades and stages of bladder cancer. Nevertheless, statistical analysis showed no significant association between promoter methylation of hTERT, TWIST1, VIM and NID2 genes and tumours stage/grade (p value >0.05). Moreover, we have investigated the association between the methylation pattern of selected genes and the treatment outcome in a sub-group of non-muscle-invasive bladder cancer cases (52/70). Hypermethylation of hTERT, TWIST1, VIM and NID2 was detected in 83.34%; 66.67%; 83.34% and 58.34% of recurrent cases, respectively, and in 80%; 80%; 80% and 60% of progressive cases, respectively. Statistical analysis highlighted a significant association between TWIST1 hypermethylation and tumour recurrence (p = 0.041<0.05). Our results indicate that hypermethylation of hTERT, TWIST1, VIM and NID2 genes is a frequent epigenetic event in bladder cancer and could be a promising therapeutic target to prevent bladder cancer progression and metastasis.

Abstract
Mediastinal hydatid cyst is a rare disease and should be considered in differential diagnosis of mediastinal cystic lesions especially in endemic regions. This localization is very serious because of the surrounding vital structures. Surgery must be indicated immediately using conservative techniques without extensive resection when progression of dissection is difficult or dangerous. Medical treatment is necessary to prevent recurrence.

Abstract
Gastric schwannoma (GS) is a rare neoplasm of the stomach deriving from Schwann cells of the peripheral nerves in the stomach. It accounts for 0.2% of all gastric tumors and is mostly benign, slow-growing and asymptomatic. Due to its rarity, GS is not widely recognized by clinicians. Preoperatively, GSs are difficult to differentiate from other mesenchymal tumors, such as gastrointestinal stromal tumor (GIST) or leiomyoma, which develop from mesenchymal stem cells. The optimal management of GS is based on the symptoms of the patient, tumor size and histologic grading. Here, we report the case of a GS in a 73-year-old female who underwent a wedge gastric resection following a clinical diagnosis of GIST. A histological and immunohistochemical study was performed excluding the misdiagnosis of GIST. The histomorphological features of the lesion and absence of c-Kit and strong positivity of S100 indicated the diagnosis of GS.

Abstract
Primary angiosarcoma of the pleura is an extremely rare tumour arising from arterial or venous pulmonary vessels of various size. It is characterized by an aggressive course and a poor prognosis. The early diagnosis is challenging due to diverse clinical and radiological manifestations. We report a case of a 70 year old male with primary right pleural epitheloid angiosarcoma. The patient had a history of a two week's progressive dyspnea. CT-scan showed a prominent thikening of the right pleura associated with pleural effusion and atelectasis. CT-scan guided by biopsy was performed and histological examination showed a tumor proliferation consisting of sheets of polygonal and epitheloid cells showing rudimentary vascular differentiation. Immunohistochemically, tumor cells were strongly positive for CD31 and Factor VIII-related antigen, negative for CD34, weakly and focally positive for EMA and Cytokeratine. The overall pathological and immunohistochemical features of the pleural specimens supported the diagnosis of epitheloid angiosarcma. The patient died after a week of discharge by pulsless ventricular tachycardia arrest. In addition, we also present a brief litterature review on pleural angiosarcoma. Our experience with this case suggests that comprehensive and sufficient sample collection and meticulous histological examination aided with immunohistochemical stains, particulary the endothelial markers, are required for accurate diagnosis of this rare malignancy.

Abstract
Chondrosarcoma is a rare malignant bone tumor. It can arise de novo or secondary to a malignant transformation of a benign underlying cartilage tumor. Secondary chondrosarcoma arising from solitary benign osteochondroma is extremely rare and data show that the reported incidence of osteochondroma of the pelvis is very low. We here report the case of a 20-year old patient with chondrosarcoma secondary to malignant transformation of an osteochondroma of the right wing of ilium, adjacent to the sacroiliac joint.

Abstract
We present a case of a papillary tumour at the cerebellopontine angle in a 54-year-old man. He presented with right-sided ear pain associated with dizziness and hearing loss. The radiological diagnosis was in favor of acoustic neurinoma. Surgical excision was performed and the diagnosis of the endolymphatic sac tumour was made. Endolymphatic tumour is a low grade adenocarcinoma that originates from the endolymphatic sac. The definitive diagnosis requires a combination of clinical features, radiological finding and pathological correlation.

Abstract
We here report the case of a 46-year old female patient with a history of total hysterectomy performed in 2011 due to uterine leiomyosarcoma followed by sessions of radiotherapy, who presented with right hemicorporal sensorimotor deficit of acute onset. Clinical examination showed right pyramidal syndrome. Brain magnetic resonance imaging (MRI) revealed a left frontoparietal extra-axial aggressive tumor (A). The patient underwent surgical resection of the cerebral lesion. Anatomo-pathological examination showed fusocellular tumor proliferation (B). Tumor cells looked like discreetly atypical muscle cells and showed few mitotic figures as well focal necrosis. Tumor proliferation infiltrated the bone, the soft tisuues and the dura-mater. Immunohistochemical examination was performed which showed anti h-caldesmon-positive cells (C) and smooth muscle anti-actin-positive cells. The diagnosis of brain metastasis from leiomyosarcoma was retained. The patient underwent radiotherapy sessions with improvement of the motor deficit.

Abstract
BACKGROUND Glutathione S-transferase pi 1 (GSTP1) is a cytosolic detoxifying enzyme that protects cells against deleterious effects of oxidative stress. Deregulated expression of GSTP1 protein and aberrant promoter methylation of GSTP1 gene were reported in various human tumors and were shown to be involved in the molecular pathway for cancer development. AIMS AND METHODS In this study, we aimed to determine the expression status of GSTP1 in relation to its gene promoter methylation in Moroccan population of 30 bladder cancer (BC) patients and in two noncancerous bladder tissues used as controls. GSTP1 expression was assessed by immunohistochemistry and GSTP1 gene promoter methylation status was studied by methylation-specific PCR (MS-PCR). RESULTS Glutathione S-transferase pi 1 was expressed in the two normal tissues. In BC cases, GSTP1 expression was strong in 23.33% (7/30), moderate in 60% (18/30), and weak in 13.33% (4/30) of cases, while GSTP1 was not expressed in one cancer case (3.33%). Variability of GSTP1 expression does not correlate with high-grade cancer or invasive-stage (p > 0.05). No GSTP1 gene promoter methylation was detected in all control and cancer cases. CONCLUSION Our data suggest that GSTP1 expression is not associated with BC development, limiting its use as a biomarker for BC management in Morocco. Moreover, difference in GSTP1 expression among BC cases is not due to GSTP1 promoter methylation.

Abstract
Gliosarcoma is a very rare brain tumor accounting for 1.8 -8% of all glial tumors. It has been classified by the World Health Organization as a variant of glioblastoma. It is a tumor with double glial and sarcomatous component. Patient's clinical picture is polymorphic, imaging data are evocative, diagnosis is based on histology. Treatment is always surgical. Prognosis is closely linked to the quality of resection. We here report two clinical cases with the aim of assessing the diagnostic, therapeutic and prognostic features of this rare entity.

Abstract
BACKGROUND Urothelial bladder carcinoma (UBC) is one of the most prevalent cancers in men worldwide. Human epidermal growth factor receptor 2 (HER2) expression has been detected in a wide range of urothelial carcinoma. Despite many reports in the literature, the prognostic significance of this overexpression remains unclear. The aim of this study was to assess the expression of HER2 in urothelial bladder carcinomas and its association with clinical and pathological parameters. METHODS 103 cases of UBC were diagnosed in our department between January 2014 and December 2015. The tumor specimens obtained by transurethral resection or cystectomy were evaluated by immunohistochemistry using HER2 antibody. RESULTS HER2 protein overexpression was present in 11.7% of cases and associated with tumor grade (p = 0.003) and pathological stage (p = 0.015). In multivariate analysis, HER2 overexpression was associated only with tumor grade (P = 0.04). CONCLUSION HER2 protein overexpression is noted in patients with high grade cancer. This expression may select patients for anti HER2 targeted therapy. Future larger and prospective studies will verify the frequency of HER2 alteration and the role of HER2 in the aggressive behavior.

Abstract
Paraneoplastic syndromes are a heterogeneous group of clinical and biological manifestations caused by underling neoplasms. They can reveal ovarian teratoma which express neuroendocrine proteins, or contain mature or immature neural tissue inducing an autoimmune response. The etiological investigation is then crucial to early identification of the tumor in order to optimize the prognosis and to limit neurological sequelae. In case of ovarian teratoma, management is essentially based on surgical resection sometimes associated with immunotherapie. We report two new cases of ovarian teratoma revealed by paraneoplastic syndromes in young and menopausal woman.

Abstract
Background Pulmonary sarcomas are uncommon accounting for 0.5 % of all primary lung cancers. Undifferentiated sarcomas account for up to 20 % of soft tissue sarcomas. A lung tumor revealed to be an undifferentiated sarcoma with epithelioid features has never been reported in the literature. Case presentation A 61-year-old white Moroccan man presented with 2 months’ history of hemoptysis and dyspnea. Chest computed tomography showed a cystic mass involving the lower field of his right lung evoking first a hydatid cyst. Abdominal computed tomography revealed bilateral adrenal nodules. Surgical resection of the lung mass was performed. On pathological examination, the tumor was cystic containing necrotic material. A histological diagnosis of undifferentiated sarcoma with epithelioid features was made. A positron emission tomography scan showed involvement of his pleura, left colon, adrenal glands, left thigh muscle, and leptomeninges. Conclusions Undifferentiated sarcoma with epithelioid features is a rare malignant mesenchymal tumor. Clinical and radiological features are not specific. A differential diagnosis includes sarcomatoid carcinoma, malignant mesothelioma, melanoma, and other epithelioid sarcomas.

Abstract
Background Primary thyroid lymphoma is an uncommon pathological entity that accounts for only 1 to 5 % of all thyroid malignancies. Primary Burkitt lymphoma of the thyroid gland is very rare. This article presents the first Moroccan case of a primary BL of the thyroid to be reported in the literature to date. Case presentation We describe here a case of a 70-year-old male who developed a rapidly enlarging thyroid gland with progressive symptoms of compression. Core biopsy confirmed the diagnosis of Burkitt lymphoma. The patient died of septic shock, 2 weeks after the first cycle of appropriate therapeutic chemotherapy. Conclusions This presentation emphasizes the importance of considering lymphoma when dealing with a thyroid mass, as its management is different from that of other thyroid pathologies, and affords an opportunity to review a very rare type of primary thyroid lymphoma.

Abstract
Background Phyllodes tumors are rare fibroepithelial tumors accounting for less than 1 % of all breast neoplasms. They are malignant in 20 % of cases. Only a few cases of malignant phyllodes tumors metastatic to bone have been reported. Case presentation Case 1: A 40 year-old white woman presented with three-week history of pain and functional impairment of the left lower limb. Her clinical past was remarkable for previous left mastectomy and radiotherapy for malignant phyllodes tumor performed one year ago. Computed tomography revealed a moth-eaten appearance of the left femoral head. The patient underwent computed guided femoral head biopsy. Pathological findings were consistent with metastatic malignant phyllodes tumor. The patient received ifosfamide and adriamycin chemotherapy. She is doing well without any evidence of progression on her imaging follow- up after 8 months. Case 2: A 48 year-old white woman, with history of bilateral mastectomy and radiotherapy for malignant phyllodes tumor performed one and two year ago, presented with four-week left lower quadrant abdominal pain. Computed tomography and magnetic resonance imaging revealed a solid aggressive osteolytic mass of the left iliac bone with extensive soft tissue invasion. Biopsy of the tumor was performed and showed a sarcomatous proliferation consistent with metastatic malignant phyllodes tumor. The patient received the same chemotherapy regimen as in the first case but without any response on her imaging follow up after 6 months. Conclusion Malignant phyllodes tumor is a rare and aggressive fibroepithelial neoplasm. An accurate diagnosis of metastases should be based on clinicopathological correlation allowing exclusion of differential diagnoses. The goal of successful managing this tumor is early detection and complete resection prior to dissemination.

Abstract
Le cancer bronchique reste parmi les cancers les plus agressifs malgré les avancées diagnostiques et thérapeutiques, les métastases à distance constituent l’élément majeur d'un mauvais pronostic. Nous rapportons une observation de métastases musculaires chez un patient porteur d'un cancer du poumon inopérable. La détection de cette métastase était grâce au TEP scan au 18 FDG. Ce bilan a conduit à un traitement par chimiothérapie systémique après biopsie exérèse de la localisation fessière. Les métastases musculaires squelettiques du cancer bronchique sont rares mais bien qu'indiquant un mauvais pronostic, elles sont accessibles à un traitement local efficace.

Abstract
Background Leiomyosarcoma is a rare malignant mesenchymal tumor that represents 5–7 % of all soft tissue sarcomas. The occurrence of this tumor in the salivary glands is exceptional. Only five cases are reported in the submandibular gland. Case presentation A 65-year-old white Moroccan woman presented with a history of progressive right submandibular swelling which had grown over a period of 8 months. Clinical examination showed a submandibular painless, mobile and hard mass without cervical lymphadenopathy. Ultrasonography and computed tomography revealed a solid and heterogeneous mass measuring 4 × 2 cm involving the submandibular gland. A resection of the gland was performed. Pathological findings were consistent with primary leiomyosarcoma of the submandibular gland. No recurrence occurred after two months of follow-up. Conclusion Primary leiomyosarcoma of the submandibular gland is an extremely rare mesenchymal tumor. Clinical and radiological features are not specific. Differential diagnosis includes metastatic leiomyosarcoma and gastrointestinal stromal tumor, myoepithelioma, sarcomatoid carcinoma, melanoma and other sarcomas. Little is known about the overall biologic behavior of this tumor, but the prognosis seems to be poor.

Abstract
Pure sarcomas of the breast are uncommon, accounting for less than 1% of primary breast malignant tumors. Mammary osteogenic sarcomas are very rare and less than 100 cases have been reported in literature. They mainly affect older and middle aged women and are highly aggressive. We report an additional case in a 56-year-old woman. Histological and immunohistological characteristics were similar to those described in other localizations. Differential diagnosis involves phyllodes sarcoma, breast metaplastic carcinoma with chondroid and osteoid differentiation, osteosarcoma of the ribs, and metastatic osteosarcoma. The prognosis is poor.

Abstract
Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract, originating from the interstitial cells of Cajal and most frequently expressing CD-117, a C-kit proto-oncogene, which can be detected immunohistochemically. Extra-gastrointestinal stromal tumors are neoplasms with similar immunohistological features arising outside the gastrointestinal tract with no connection to the gastric or intestinal wall.We report the case of a 61-year-old Moroccan man who presented with chronic abdominal pain along with progressive abdominal distension for the past last year. The clinical examination demonstrated a large abdominal mass and an abdominal computed tomography scan revealed a voluminous intraperitoneal mass measuring 30 cm in its greatest diameter. At laparotomy, this mass seemed to be arising from the greater omentum without continuity to the gastrointestinal tract. The mass was completely removed with clear margins and pathological examination was suggestive for high-risk gastrointestinal stromal tumor of the greater omentum. Due to the aggressive nature of this patient's tumor, he was assigned to receive imatinib as adjuvant chemotherapy for 3 years. He remains alive without any sign of recurrence after 4 years of follow-up.Extra-gastrointestinal stromal tumors of the greater omentum can grow slowly and remain clinically silent despite the large size of the tumor. Complete surgical resection is the only effective treatment approach. Nevertheless, adjuvant therapy following resection with imatinib has become a standard of care in cases of high risk disease.

Abstract
Background Insulinomas are rare pancreatic endocrine tumors. Most are benign and solitary. However, the nonspecific symptoms and small size of these tumors led to difficulties of diagnosis and localization. Case presentation We present two Arab patients with pancreatic long-standing insulinoma. Both patients presented episodic hypoglycemic symptoms respectively during 10 and 2 years. Biochemical and morphological workup detected localized pancreatic insulinoma. Open procedure surgery was done for the two patients and insulinomas were successfully removed by enucleation. Conclusion Insulinoma remains a diagnostic challenge to practitioners. Diagnosis of suspected cases is easily confirmed by standard endocrine tests, especially the supervised fasting test. Accurate preoperative localization is essential for more effective and safest surgery.

Abstract
Ovarian fibroma is the most common benign solid tumors of the ovary, commonly misdiagnosed as uterine fibromaor as malignant ovarian tumors. It occurs generally in older perimenopausal and postmenopausal women. Occasionally large fibromas may undergo torsion causing acute abdominal pain. Doppler Ultrasonographyimaging is the choice study. CT and MRI are often needed for further characterization and differentiation from other solid ovarian masses. The choice treatment is surgical removal with intraoperative frozensection. Immunohistochemicalanalysis is recommended to rule out the differential diagnosis. Here we present a case of a postmenopausal woman with a large twisted ovarian fibroma reflecting diagnostic and management difficulties including potential misdiagnosis of the tumor as a malignant ovarian neoplasm that may influence the surgical approach.

Abstract
Adenoid cystic carcinoma is a malignant epithelial neoplasm derived from the salivary glands. Primary adenoid cystic carcinoma of the cervix is extremely rare, accounting for less than 1% of all cervical carcinomas. Its origin is debatable. It generally presents in elderly age group, however only twenty three cases have been reported in women less than age 45 years old. In this paper we report two new cases of primary adenoid cystic carcinoma in younger women and include the cytopathology and histopathology findings. A 36, 41 year-old women were admitted with signs and symptoms suggestive of a cervical cancer. Speculum examination showed a firm mass in the uterine cervix. The diagnosis of adenoid cystic carcinoma was confirmed by the histopathology examination of the biopsy specimen in the two patients, which characteristically revealed the presence of a cribriform pattern and cylindromatous structures of the tumor cells, adhered around hyaline stoma. They were managed successfully by concurrent radiotherapy. Adenoid cystic carcinoma of the cervix is a rare disease. It usually occurs in an elderly age group. We report these two cases because of its rarity in young patients, with description of illustrative pathology and discussion on the histological diagnosis.

Abstract
Primary malignant tracheal tumors are not common and adenoid cystic carcinoma (ACC) of trachea is very rare. The diagnosis is often delayed due to the atypical symptoms. We report an extremely rare case of ACC of proximal trachea, in a 55-year-old female who presented with a 12 month history of progressive dyspnea. Laryngoscopy and computed tomography revealed a broad-based polypoidal mass arising from posterior wall of the proximal trachea. Biopsy confirmed the diagnosis of ACC. The patient underwent a complete surgical resection and post operative radiotherapy. Six months follow-up of the patient did not reveal local recurrence or distant metastases. The literature of tracheal ACC is reviewed.

Abstract
Adenoid cystic carcinoma (ACC) of the trachea is rare, it represents 1% of all respiratory tract cancers. It's generally considered as a slow-growing, with pronlonged clinical course. Most patients present with dyspnea, and the symptoms often mimic those of asthma or chronic bronchitis Surgical resection is the mainstay of treatment often combined to radiotherapy because of close surgical margins. When surgery isn't possible, most tumors respond to radiotherapy alone wich often results in long periods of remission We report two cases of primary ACC of trachea: a 49 year old male presented a distal unresectable tracheal ACC treated with chemo-radiotherapy who developed a recurrence and died 7 years after the diagnosis. And a 50 years old female with a proximal tracheal tumor treated by surgical resection and end- to- end anastomosis followed by adjuvant radiotherapy. At 10 months follow-up, our patient shows no evidence of disease with negative histological findings.

Abstract
Context: Gliosarcoma is a rare variant of glioblastoma multiforme containing distinct gliomatous and sarcomatous components. Gliosarcoma comprise 1.8–8% of glioblastoma multiforme and are clinically similar to them, affecting adults in the fourth and sixth decades of life, with a higher proportion found in males. The survival for patients with Gliosarcoma is equally poor as for those with glioblastoma multiforme, and there is a greater propensity for extracranial metastasis in Gliosarcoma. Clinical treatment-related experience reported in the literature is limited, and Gliosarcoma are currently treated in a similar fashion to glioblastoma multiforme, with modalities including tumor resection, postoperative radiation therapy, and chemotherapy. Gliosarcoma can arise secondarily, after conventional adjuvant treatment of high-grade glioma. The current literature on the occurrence of secondary gliosarcoma after glioblastoma multiforme is limited, with only 54 reported cases. Case Report: The authors present a 48-year-old Caucasian male who had previously received postoperative combined radiation and temozolomide chemotherapy for glioblastoma multiforme. After a free disease period of 9 months the disease recurs as Gliosarcoma. The patient underwent a Total surgical excision and received chemotherapy with a basis of bevacizumab and irinotecan. The patient died from tumor progression 5 months after gliosarcoma diagnosis. Conclusion: The poor survival of patients with secondary gliosarcoma who had previously received combined radiation and temozolomide chemotherapy for glioblastoma multiforme may reflect a unique molecular profile of glioblastoma multiforme that eventually recurs as secondary gliosarcoma. We have to keep in mind the possibility of gliosarcomatous change in the recurrence of malignant glioma. Awareness of this pathological entity will allow more rapid diagnosis and treatment.

Abstract
Syringomatous carcinoma is a rare cutaneous neoplasm, most frequently situated on the face and scalp and histologically characterised by an infiltrative pattern of basaloid or squamous cells, a desmoplastic stromal reaction and keratin filled cysts. We report the case of a 76-year-old woman who presented an ulcerative interscapular lesion measuring 3x4cm. After resection, the histological examinations of the specimens have identified a basal cell carcinoma. However, a local recurrence was observed 18 months later; histopathological findings showed a syringomatous pattern and neoplastic epithelial cells arranged in interconnecting cords with microcystic areas. Nests, cords, and tubules of the tumour extended into the dermis and into the adjacent muscle. Sclerosis of stroma around the cords was present. Tumour cells were not connected to the epidermis. The immunohistochemical analysis showed positivity for anti-CK7, AE1/AE3 and negativity for anti CEA and anti CK20. These histological and immunohistochemical analyses were consistent with the diagnosis of syringomatous eccrine carcinoma. Syringomatous carcinoma is an extremely invasive tumor, locally destructive and slowly growing adnexal tumour, derived from eccrine sweat glands. It is often mistaken, both clinically and microscopically, for other benign and malignant entities. The tumour recurrence is high due to extensive perineural invasion, but regional or distant metastases are rare. The local aggressive nature of the tumour and the high recurrence rate may necessitate mutilating procedures. Optimal treatment consists of a complete microscopically controlled surgical excision with clear surgical margins.

Abstract
Gliosarcoma is a rare tumor of the central nervous system, consisting of gliomatous and sarcomatous elements. The glioblastoma can undergo a change in phenotype, transforming into a gliosarcoma, especially when the tumor has been treated with radiotherapy. Features unique to gliosarcoma compared to glioblastoma include their potential to appear similar to a meningioma at macroscopy, repeated reports of metastases and infrequency of EGFR mutations. We present a case of secondary gliosarcoma to emphasize on the specificities, essentially diagnostical of this rare entity.
