<b><br>Introduction:</b> We report our experience in the treatment of parotid cancers by radiotherapy delivered with curative intent over a period of 10 years.</br> <b><br>Aim:</b> The aim of this study was to evaluate the therapeutic results and prognostic factors.</br> <b><br>Materials and methods:</b> This is a retrospective study of patients with parotid cancer treated with radiotherapy between 2008 and 2017 at the National Institute of Oncology in Rabat. Patients who received adjuvant or exclusive radiotherapy were included in this study. We performed a multivariate analysis for the factors related to locoregional control and overall survival.</br> <b><br>Results:</b> Initially, 74 patients (45 men and 29 women), at a median age of 57 years. were identified. At the time of diagnosis, 10 (13.6%), 36 (48.6%), and 28 (37.8%) patients were in stage II, III, and IVab, respectively. Sixty patients received adjuvant radiotherapy after parotidectomy and 14 patients received exclusive radiotherapy for an unresectable tumor. At 5 years, the rate of locoregional control and overall survival were 68.2% and 53.7%, respectively. Surgical resection and negative margins were significantly correlated with locoregional control. Lymph node involvement, unresectable tumors, high-grade histological types, and cystic adenoid carcinoma were significantly correlated with poor overall survival.</br> <b><br>Conclusions:</b> Acceptable long-term results are obtained with surgery combined with radiotherapy. Surgical resection remains essential for parotid cancer, given the disappointing results of treatment with radiotherapy alone.</br>.

Review
c-KIT is an important diagnostic marker in salivary gland tumours and is expressed in most adenoid cystic carcinomas. Histologically similar salivary gland tumours with variable immunohistochemical expression for c-KIT pose a challenge and make diagnostic reliability ambivalent. An electronic search was performed in MEDLINE by PubMed, Google Scholar, Scopus, Trip, Cochrane Library, and EMBASE up to 31 December 2023, without period restriction. The articles that investigated CD117 or c-KIT in salivary gland tumours were included for review. Sensitivity, specificity, and positive and negative predictive values of c-KIT immunohistochemical expressions were derived and subjected to meta-analysis using Open Meta analyst for Sierra software. The risk of bias in selected studies was analysed using the QUADAS-2 tool, and RevMan 5.4 was used to output the result. Forty-three articles were reviewed, and 2285 salivary gland cases were analysed. Adenoid cystic carcinoma had an overall expression of 84.9%. A similar expression was found in epimyoepithelial carcinoma (79.1%), lymphoepithelial carcinoma (75%), myoepithelial carcinoma (60.8%), monomorphic adenoma (94.1%), and pleomorphic adenoma (74.7%). The sensitivity, specificity, and positive and negative predictive values of c-KIT/CD117 for adenoid cystic carcinoma with other salivary gland tumours were 84.99%, 69.09%, 84.79%, and 69.41%, respectively. Current evidence shows that c-KIT, despite its sensitivity, is not specific and therefore cannot be a useful diagnostic marker for distinguishing adenoid cystic carcinoma from other salivary gland tumours. Further research on other salivary gland tumours that exhibit comparable expression is necessary to validate the diagnostic accuracy of c-KIT.

Oncocytic mucoepidermoid carcinoma (OMEC) is an uncommon variant of mucoepidermoid carcinoma. Histopathologically, it is characterised by the predominance of cells with large polygonal morphology and with an abundance of eosinophilic granules. We present a rare case of OMEC manifested as painless palatal swelling in a 25-year-old young male. The overlying mucosa was normal in appearance, with no evidence of ulceration or discharge. Histopathology examination showed the presence of sheets of mucous and intermediate cells along with cystic areas of variable sizes and shapes. On high power magnification, oncocytes were evident, showing abundant granular eosinophilic cytoplasm with central dark round nuclei. Around 75-80% tumour cell population was composed of oncocytic cells. The predominant presence of oncocytes can present diagnostic difficulties to pathologists due to overlapping features with adenoid cystic carcinoma, oncocytoma, acinic cell carcinoma, Warthin's tumour, and other oncocyte tumours. Although the presence of oncocytes is a pathognomonic feature, the role of immunohistochemistry and genetic analysis in diagnosis is discussed in the present paper. Moreover, considering its behaviour as a low-grade MEC, it is prudent to avoid an aggressive treatment strategy and prevent unwarranted morbidity. We recommend prospective studies to better understand the factors that influence the prognosis of OMEC.

Adenoid cystic carcinoma is a rare malignant tumor that primarily occurs in the salivary glands. There are few reports of sublingual gland adenoid cystic carcinoma with lung metastases on which F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG-PET/CT) was performed. We report the case of a 57-year-old Japanese woman with an adenoid cystic carcinoma of the sublingual gland with lung metastases in whom the FDG uptake of the lung metastasis was low despite high FDG uptake in the primary lesion. The pathological examination revealed that solid components were more visible and the Ki-67 index was more positive in the primary lesion compared to the metastatic lesion. We speculate that differences in tumor growth ability might have resulted in the differences in FDG uptake. This case demonstrates that significant differences might occur in the FDG uptake between primary and metastatic tumors.

OBJECTIVE
Quality of life (QoL) assessments are increasingly important for evaluating the well-being of children with Obstructive Sleep Apnea Syndrome (OSAS). This study's objective is to culturally adapt and validate the Turkish version of the OSA-18 questionnaire, a commonly used tool for assessing QoL in children with OSAS.
METHODS
The OSA-18 questionnaire was translated and culturally adapted for use in the Turkish-speaking population. The study was conducted with 180 participants, 100 boys and 80 girls, with a mean age of 6.16±2.14 years. The participants were divided into two groups. The patient group comprised individuals with symptoms of OSAS based on clinical evaluation, including anamnesis, physical examination, and video recording of apnea and snoring. The patient group underwent adenotonsillectomy and their caregivers completed the Turkish version of the OSA-18 scale postoperatively. The control group comprised 90 children who were similar to the patient group in terms of gender and age. These children had no major complaints such as snoring, apnea, fatigue during the day, irritability, or distraction. In the physical examination of this group, no major tonsillar or adenoid hypertrophy, which causes significant stenosis in the upper airway, was observed. Internal consistency, reliability, validity, responsiveness, and factor analysis were assessed.
RESULTS
The Turkish version of the OSA-18 questionnaire demonstrated excellent reliability, with a Cronbach's alpha of 0.929. The test-retest results were not statistically different. Validity was confirmed through a positive correlation between the OSA-18 score and external parameters, such as the Mallampati score, and tonsil and adenoid size. We found a statistically significant reduction in OSA-18 scores postoperatively, signifying a robust responsiveness to the intervention.
CONCLUSION
Our study confirms the suitability of the Turkish OSA-18 questionnaire for assessing the QoL in children with OSAS. This quick and easy-to-use tool will be valuable for future research on Turkish-speaking children with OSAS, aiding in the evaluation of pediatric OSAS and QoL.

Adenoid cystic/Basal-cell carcinoma (ACC/BCC) of the prostate is a rare histological type exhibiting various morphological characteristics and an optimal treatment has not yet been established. We report the case of a 63-year-old patient who complained of incomplete bladder emptying and recurrent urinary infection six months after transurethral resection of a high-grade urothelial bladder tumor. The clinical features, digital rectal examination, serum PSA levels, and multiparametric MRI did not refer to any suspicious prostatic lesions and cystoscopy revealed bladder neck hypertrophy, and yellowish zones in the prostatic urethra. Transurethral resection was performed due to these findings and histopathological analysis showed poorly differentiated ACC/BCC of the prostate. Even though there is no proven mutual correlation between ACC/BCC and urothelial bladder cancer, the appearance of obstructive urinary symptoms, bladder-neck hypertrophy, and macroscopic changes in prostatic urethra should be reconsidered for transurethral resection biopsy considering the possibility of ACC/BCC.

Meta-Analysis
Head and neck adenoid cystic carcinoma (HNACC) is a radioresistant tumor. Particle therapy, primarily proton beam therapy and carbon-ion radiation, is a potential radiotherapy treatment for radioresistant malignancies. This study aims to conduct a meta-analysis to evaluate the impact of charged particle radiation therapy on HNACC. A comprehensive search was conducted in Pubmed, Cochrane Library, Web of Science, Embase, and Medline until December 31, 2022. The primary endpoints were overall survival (OS), local control (LC), and progression-free survival (PFS), while secondary outcomes included treatment-related toxicity. Version 17.0 of STATA was used for all analyses. A total of 14 studies, involving 1297 patients, were included in the analysis. The pooled 5-year OS and PFS rates for primary HNACC were 78% (95% confidence interval [CI] = 66-91%) and 62% (95% CI = 47-77%), respectively. For all patients included, the pooled 2-year and 5-year OS, LC, and PFS rates were as follows: 86.1% (95% CI = 95-100%) and 77% (95% CI = 73-82%), 92% (95% CI = 84-100%) and 73% (95% CI = 61-85%), and 76% (95% CI = 68-84%) and 55% (95% CI = 48-62%), respectively. The rates of grade 3 and above acute toxicity were 22% (95% CI = 13-32%), while late toxicity rates were 8% (95% CI = 3-13%). Particle therapy has the potential to improve treatment outcomes and raise the quality of life for HNACC patients. However, further research and optimization are needed due to the limited availability and cost considerations associated with this treatment modality.

Klippel-Feil syndrome (KFS) is a triad comprising cervical spine fusion, a low posterior hairline, and constrained neck movement. This triad is not universally present. The most frequent accompaniment is Sprengel's scapula deformity. According to the Feil classification, Class 1 (C1) is an immense fusion of many cervical vertebrae, Class 2 (C2) is a fusion of one or two vertebrae only, and Class 3 (C3) is coupled with thoracic and lumbar spinal vertebral fusion in addition to the fusion of the cervical vertebrae. Clarke's categorization of KFS includes other associated anomalies. The different classification systems for KFS have been made by the different specialists to whom patients may present, which include orthopedic surgeons, neurosurgeons, orthodontists, faciomaxillary surgeons, cardiologists, and pediatricians. This anomaly being rare and the lack of universally accepted classification may lead to confusion regarding the identification of the syndrome, especially the Clarke Type 3 with isolated facial dysmorphism may go undiagnosed. We report a case with KFS-Clarke Type 3 with isolated facial dysmorphism and Feil Type 2 with the fusion of C2-C3 cervical vertebrae, detected as an incidental radiologic finding, and initial impression of adenoid facies. Hence, this case also highlights the contrasting features between the facial dysmorphism of Clarke Type 3 KFS and adenoid facies.

Review
Breast cancers of either ductal or lobular pathology make up the vast majority of breast malignancies. Other cancers occur rarely in the breast. Benign pathology can at times mimic breast cancers on imaging and initial needle biopsies. We report a rare breast pathology of cylindroma. Cylindromas are usually benign, rare dermatologic lesions most commonly associated with head or neck locations. They more commonly occur as sporadic and solitary masses. Less commonly is an autosomal-dominant multi-centric form of this disease. Malignant cylindromas are very rare. We present a patient with findings of a cylindroma of the breast after excision. This was initially felt to be concerning for breast cancer on imaging and core biopsy. Treatment of cylindromas of the breast is excision. Sentinel lymph node dissection is not indicated, nor are adjuvant therapies when identified in the breast. This lesion needs to be included in the differential diagnosis for breast cancer. If cylindromas can be accurately diagnosed preoperatively, this would negate the need for consideration of axillary nodal surgery and adjuvant therapies.
