Abstract
The fifth edition of the World Health Organization (WHO) Classification of Tumors of the Central Nervous System has identified many new tumor types and has established, for the first time, essential and desirable diagnostic criteria for each of them. Among these, genetic alterations play an important role associated with morphology. For the first time, epigenetic data can also constitute essential and/or desirable criteria. These genetic abnormalities can be fusions, deletions or gains/amplifications and can thus be detected by fluorescence in situ hybridization techniques. The purpose of this article is to present the advantages and limitations of this technique in reference to its specific use within neuro-oncopathology in light of the 2021 WHO classification.

Abstract
Multiple endocrine neoplasia (MEN) are genetic predisposition syndromes to endocrine tumors including MEN1, MEN2 and exceptionally MEN4. MEN are transmitted in an autosomal dominant fashion with a high penetrance. Classically, there is no genotype/phenotype correlation for NEM1 whereas this is the case for NEM2. Patients with NEM1, linked to an inactivating mutation of the menin gene, may present with: primary hyperparathyroidism, pituitary adenoma, duodeno-pancreatic neuroendocrine tumors (NETs), bronchial tumors with an increased risk of thymoma, adrenal cortical tumors, an increased risk of breast cancer and characteristic skin involvement such as collagenomas, lentiginomas and an increased risk of skin cancer. These patients require at least annual follow-up. Screening of children is proposed from the age of 5 years. Patients with NEM2, linked to an activating mutation of the RET proto-oncogene, all present with medullary thyroid carcinoma (MTC) at a variable age depending on the genotype. Some patients present a pheochromocytoma (50 %) and hyperparathyroidism (20 %). Pediatric forms with aggressive CMT, ganglioneuromatosis and marfanoid syndrome exist (rare NEM2B). Some mutations are associated with a risk of aggressive CMT, justifying prophylactic thyroidectomy before 6 months of age. The age of genetic testing depends on the mutation subtype in the NEM2 parent. NEM4, related to a mutation in the CDKN1B gene, are rare, with a less well-known pathogenesis and their follow-up is not well codified.

Abstract
Postmenopausal hyperandrogenism is an androgen excess originating from either the adrenals and/or the ovaries. Clinically, symptoms can be moderate (increase in terminal hair growth, acnea) or severe with signs of virilization (alopecia, clitoridomegaly). In either setting, physicians need to exclude relatively rare but potentially life-threatening underlying tumorous causes, such as adrenal androgen-secreting tumors. The objectives of this review are to evaluate which hormonal measurements (T, delta 4 androstenedione, 17 OH progesterone, SDHEA, FSH, LH) and/or imaging (pelvic ultrasound, MRI or adrenal CT-scan) could be useful identifying the origin of the androgen excess. Our review illustrates that the rate of progression of hirsutism and/or alopecia, and serum testosterone levels are in favor of tumors. Pelvic MRI and adrenal CT-scan are useful tools for identifying the different causes of androgen excess.

Abstract
Rapid technical advances in molecular biology allowed for the identification of key genetic alterations in central nervous system (CNS) tumors. Our ever-expanding knowledge of brain tumor genetics and the development of new technologies, such as DNA-methylation profiling, required an update of the 2016 fourth edition of the WHO classification of CNS tumors. Updates were regularly published by the Consortium to Inform Molecular Practical Approaches to CNS Tumor Taxonomy-Not Official WHO (c-IMPACT-NOW) until the publication of the fifth edition of the WHO classification of CNS tumors in 2021. In that edition, new types and subtypes are introduced and criteria for histo-molecular diagnostic and grading are refined, especially for diffuse gliomas. The definition of a broad category "diffuse glioma, pediatric subtype" (low or high grade) is a major improvement of the classification. Moreover, the nomenclature was simplified and aligned with that of other blue books. The 2021 edition truly advances the role of molecular diagnostics in CNS tumor classification. Methyloma profiling may become a cornerstone of CNS tumor diagnostic. The new WHO classification will lead to better management of brain tumor patients.

Abstract
AIM Only few robust studies specify the indications of Mohs Surgery techniques in skin tumors. The aim of this work was to carry out a review of almost 10 years of experience, assessing the impact of reduced margins on reconstruction, and proposing a management algorithm in the light of the literature. PATIENT AND METHODS All the records of patients having benefited from a Mohs technique in our center were retrospectively compiled from January 2011 until January 2020. A formalin-fixed tissue Mohs surgery was used. An impact assessment of reduced margins was made both on the excisional surface but also on the improvement of the reconstruction. RESULTS 548 patients were included. Complete tumour clearance was achieved with one surgical stage in 71% of cases. The excisional surface of tumours located in the periorbital and nasal areas was significantly more often reduced compared to other areas (P=0,020). The improvement of the reconstruction was deemed significant in the periorbital and nasal areas; as well as for tumours located on limbs and trunk linked with Dermatofibrosarcoma management. CONCLUSION This study underlines the interest of assessing the clinical relevance of reducing margins depending on the tumor location. Our single-center experience feedback on a large series allows to clarify Mohs technique indications by means of a literature review.

Abstract
BACKGROUND Return-to-work after cancer depends on several factors related to the disease but also other socio-professional factors. The primary aim of this study was to identify socio-demographic, disease related and professional factors influencing the return-to-work process. METHODS It was a prospective and descriptive study reporting the return-to-work process in 89 cancer patients, in a professional activity age, who had cancer treatment and a follow up in the Oncology department in Tahar Maamouri Teaching Hospital of Nabeul, between September 2015 to December 2019. RESULTS Our study included 89 patients. Mean age was 45 years±8. The population was predominantly feminine (59 %). They were employees in 45 % of cases. Private professional sectors included 60 % of all patients. An open-ended contract was performed in 87 % of cases. Most frequent primary tumors were breast tumors (45 %) and colon tumors (20 %). Thirty-four patients went back to work after recovery. Seventy-nine percent of them were female patients and 70 % had breast cancer. Predictive factors identified in univariate statistical analysis and correlated to return-to-work were gender (P=0.002), occupation (P<10-3), initial duration off sick (P=0.015), fitting out measures at work (P=0.01), primary tumor origin (P=0.01), disease stage (P=0.037), treatment (P=0.014) and disease outcome after treatment (P=0.024). CONCLUSION Our study underlined a need to create a pluridisciplinary platform unifying collaborators among oncologists and occupational health professionals in order to enhance professional reintegration process and to hold patient's professional equilibrium after cancer recovery.

Abstract
INTRODUCTION Adipocytic tumors are the most common soft tissue mesenchymal tumors. Their occurrence in salivary glands is rare. We studied the epidemiology, the diagnostic and the therapeutic features of the salivary adipocytic tumors followed in our department. PATIENTS AND METHODS A retrospective study was conducted in our department between January 1997 and December 2011. Nine cases of adipocytic tumors of the salivary glands were found. Data were collected from medical records and processed by Excel. RESULTS Mean age was 44 with a clear predominance of males (sex ratio: 3.5). In 8 cases the tumors were benign (7 lipomas and 1 lipofibroma). The only malignant tumor was a metastatic myxoid liposarcoma. Parotid was the main location (8 cases/9). Ultrasonography and MRI were prescribed. The treatment was tumor and parotid gland removal with conservation of the facial nerve excepted in the malignant case. One transient facial palsy, two earlobe dysesthesia and one retromandibular depression were observed. No recurrence was noted. DISCUSSION Our study confirmed the epidemiological profile of these adipocytic salivary gland tumors, which are rarely observed, but mainly in the parotid gland. They are often benign and lipoma is the main histological type.

Abstract
Thoracic surgery for pediatric tumors may induce a large variety of sequelae that mainly concern skin, muscles and bones (ribs), thoracic nerve and spinal cord and respiratory system. Muscle-sparing thoracotomy, intrathoracic expanders inserted after right pneumonectomy, early orthopedic evaluation and follow-up are useful preventive proceedings able to decrease postoperative sequelae. Surgery for abdominal tumors in children is part of a sequence where each therapeutic treatment can induce its own sequelae possibly potentiated by other therapies. Scars and occlusions represent classic effects, others like diarrhea, intestinal ischemia may require specific and sometimes partially effective long-term treatment. The pelvic cavity is characterized by an anatomy dedicated to urinary and digestive continence and reproductive functions. The oncologic resection of tumors developed in this region exposed to significant risk of sequelae that may strongly affect the quality of life. The development of conservative approaches for local treatment and of fertility preservation techniques has significantly reduced this morbidity and must be known by the surgeon to optimize the therapeutic strategy.
