Solitary intraosseous schwannoma of the base and vault of the skull: a summary review of such unusual location.

Intra-osseous schwannoma is a rare mesenchymal tumor. Although, the head and neck region is one of the most common sites for schwannomas, its location at the skull bone is uncommon and accounted for less than 0.2% in the largest series of bone tumors ever reported. Furthermore, it is most often a benign tumor, malignant transformation is exceedingly rare.Clinical presentation is non-specific, most often symptoms are associated with compression and invasion of adjacent organs. Neuro-imaging features are non-specific and the diagnosis is based on histological examination with immunohistochemical study.Surgery remains the aim of treatment. However, radiation therapy could be an interesting therapeutic option in unresectable tumors.This systemic review offers new clinicopathological data useful for better defining the diagnosis and clinicopathological behavior of schwannoma. The purpose of this work is to raise awareness among clinicians adding this clinical entity as a differential diagnosis when a mass of skull bone is identified.

NEUROBLASTOMA IN AN ADULT: A CASE REPORT OF A RARE ENTITY WITH A SUMMARY REVIEW

Neuroblastoma is a very uncommon neoplasm in adulthood. It occurs almost exclusively in children younger than 10 years (More than 90% of cases). We report the case of a healthy 40-year-old male who complained of a right flank pain in 2010. Clinical examination revealed an enormous abdominal mass involving the adrenal gland as showed at abdominal CT scan. The patient underwent a surgical en-bloc excision of the right adrenal mass, after a laborious dissection of the tumor. Histological and immunohistochemical findings were suggestive of a neuroblastoma. Adjuvant treatment was not indicated since the complete gross excision of the tumor was performed, and subsequently the patient was considered stage 1 disease and because of the unavailability of MYCN status, necessary for achieving risk group stratification and a risk-adapted strategy. The patient remained in good local control, until January 2015 when he accused a locoregional and metastatic relapse consisting of two new para-renal masses and magma of celiac adenomegalies extending into the mediastinum. As the mass was considered unresectable, therapeutic decision of administrating neoadjuvant chemotherapy, followed by local treatment (surgery and / or radiotherapy) based on tumor response was taken. Given the bad tumor response to systemic treatment, a palliative radiotherapy was instaured. Currently the patient is two months after the end of radiation with mild clinical improvement. The purpose of presenting this case is not only to report an uncommon malignancy in adulthood, but also to raise awareness among clinicians adding this clinical entity as a differential diagnosis when a retroperitoneal mass is identified. We also conducted a literature review to enhance cliniciansÂ’ acknowledgment about the management of this rare entity in adults.

Quelle prise en charge nutritionnelle des patients atteints du cancer de la sphère oto-rhino-laryngée traités par la radiothérapie ? Une mise au point

Radiotherapy is an effective treatment for head and neck cancers but patients often experience side effects, which lead to malnutrition. Morbidity related to weight loss during treatment may include dehydration, hospitalization, compromised treatment efficacy, and reduced quality of life and may impact survival hence the importance of early nutritional management prior to radiotherapy. Multiple interventions have been implemented to help ameliorate the impact of treatment on weight loss and nutritional status, including the use of percutaneous endoscopic gastrostomy tubes. The goal of this overview is to search the predictive factors of malnutrition and an overview of the different types of nutritional interventions and their impact on the local control of the disease, mortality and quality of life of patients treated with radiotherapy or concomitant chemoradiotherapy.
