J Prosthet Dent 2023:S0022-3913(23)00699-6. [PMID: 38030545 DOI: 10.1016/j.prosdent.2023.10.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 10/05/2023] [Accepted: 10/06/2023] [Indexed: 12/01/2023]
Abstract
Unique challenges are encountered when providing an obturator for an adolescent patient. Challenges include the need to modify the obturator throughout growth, engaging the mixed dentition or partially erupted teeth with minimal undercuts, the psychosocial challenges of an actively maturing patient, and the possible need for coincidental orthodontic therapy. This clinical report describes the ongoing rehabilitation of a patient who presented at the age of 10 with a biopsy-confirmed palatal mucoepidermoid carcinoma. Incorporating orthodontic brackets for retention of innovative adjustable obturator clasps allowed for the favorable function of the obturator prosthesis and the ability to alter the prosthesis over time.

Analysis of Human Papilloma Virus Content and Integration in Mucoepidermoid Carcinoma. Viruses 2022; 14:v14112353. [PMID: 36366450 PMCID: PMC9698779 DOI: 10.3390/v14112353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 10/21/2022] [Accepted: 10/22/2022] [Indexed: 02/01/2023] Open
Abstract
Mucoepidermoid Carcinomas (MEC) represent the most common malignancies of salivary glands. Approximately 50% of all MEC cases are known to harbor CRTC1/3-MAML2 gene fusions, but the additional molecular drivers remain largely uncharacterized. Here, we sought to resolve controversy around the role of human papillomavirus (HPV) as a potential driver of mucoepidermoid carcinoma. Bioinformatics analysis was performed on 48 MEC transcriptomes. Subsequent targeted capture DNA sequencing was used to annotate HPV content and integration status in the host genome. HPV of any type was only identified in 1/48 (2%) of the MEC transcriptomes analyzed. Importantly, the one HPV16+ tumor expressed high levels of p16, had high expression of HPV16 oncogenes E6 and E7, and displayed a complex integration pattern that included breakpoints into 13 host genes including PIK3AP1, HIPI, OLFM4,SIRT1, ARAP2, TMEM161B-AS1, and EPS15L1 as well as 9 non-genic regions. In this cohort, HPV is a rare driver of MEC but may have a substantial etiologic role in cases that harbor the virus. Genetic mechanisms of host genome integration are similar to those observed in other head and neck cancers.

Metastatic mucoepidermoid carcinoma to the pleura: a case report. J Med Case Rep 2022; 16:69. [PMID: 35168684 PMCID: PMC8848957 DOI: 10.1186/s13256-022-03285-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 01/21/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Mucoepidermoid carcinoma is the most common malignant neoplasm arising from the salivary glands (Ali et al. in J Ayub Med Coll Abbottabad 20(2): 141-2, 2008, Xi et al. in World J Surg Oncol 10: 232, 2012). When arising from anatomic sites other than the salivary glands it can be a diagnostic challenge. Primary and metastatic mucoepidermoid carcinoma from and to the pleura are extremely rare entities that are frequently misdiagnosed as adenocarcinoma, adenosquamous carcinoma, or squamous cell carcinoma (Xi et al. in World J Surg Oncol 10: 232, 2012). CASE PRESENTATION We describe an unusual case of a 64-year-old Caucasian female patient with metastatic high-grade mucoepidermoid carcinoma to the pleura, morphologically resembling squamous cell carcinoma. Molecular studies of both the parotid gland and pleural tumors helped prove the metastatic nature of the pleural lesion. CONCLUSIONS Metastatic mucoepidermoid carcinoma to the pleura is a rare entity, frequently misdiagnosed as squamous cell carcinoma. Differentiating between a lung primary and a metastatic disease has treatment implications and prognostic significance for the patient. When morphologic and immunophenotypic overlap exists, molecular testing can help distinguish mucoepidermoid carcinoma from other neoplasms.

Abstract
BACKGROUND Cervical abscesses frequently occurred in pediatric patients. Surgical drainage is currently recommended in the cases not responding to medical therapy. Needle aspiration may represent a simple, effective and minimally invasive treatment for acute neck suppuration in selected cases. OBJECTIVE To evaluate the effectiveness of needle aspiration in the treatment of cervical abscesses in pediatric age as an alternative to surgical drainage. METHODS From November 2013 to November 2019, at the ENT Department of the "Bambino Gesù" Pediatric Hospital, Rome, we treated 47 children with cervical abscess by performing aspiration with a 19 G needle in wakefulness after applying local anesthetic. Parenteral antibiotic treatment was associated with all patients both before and after treatment. RESULTS Complete regression of the abscess occurred in 46 children with no evidence of recurrence in the follow-up period. Surgical drainage was required in only one patient due to the lack of resolution of the abscess episode. No complications such as hematomas or hypertrophic scars were found in any patient. CONCLUSIONS Our results confirm the effectiveness of needle aspiration in the treatment of cervical abscesses in children as an alternative to surgical drainage.

Abstract
PURPOSE OF REVIEW Salivary tumors are uncommon among children but are more likely to be malignant compared with adults. A lack of experience makes consensus in treatment elusive. Amidst recent publication of large institutional and national series, this review aims to discuss the epidemiology, diagnosis, investigation, and treatment for pediatric epithelial salivary malignancies. RECENT FINDINGS Pediatric salivary malignancies are often low grade and carry a favorable prognosis. High-grade tumors portend an increased risk of recurrence and a decreased survival. Surgeons should strive for oncologic resection with clear margins and avoid enucleation and excisional biopsies. Overt nodal metastases require concurrent neck dissection, whereas elective neck dissections may be reserved for cases with high risk of occult disease, such as advanced stage and high-grade neoplasms. Adjuvant radiation should be considered in high-grade tumors. SUMMARY The paucity of high-level evidence clouds treatment decisions and further encourages pediatric salivary malignancies to be treated in an experienced center with a multidisciplinary approach.

Fine-Needle Aspiration Cytology Is an Effective Diagnostic Tool in Paediatric Patients with Mucoepidermoid Carcinoma as Secondary Neoplasm. Acta Cytol 2020; 64:520-531.

Abstract
BACKGROUND Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumour in paediatric population, accounting for 16% of all cases. Patients affected by a previous solid or leukaemic neoplasm during their childhood may develop a second different tumour during the follow-up. In this setting, salivary gland MEC is relatively frequent, accounting for 6% of the second neoplasms in paediatric patients. Consequently, the occurrence of salivary gland nodules in paediatric patients with a previous neoplasm should be considered an event with a high risk of malignancy that poses peculiar diagnostic challenges. SUMMARY This study was designed to define clinical and instrumental findings and morphological features of MEC on fine-needle aspiration cytology (FNAC) samples in paediatric patients with and without a previous neoplasm. Five patients under 19 years are included in this series. FNAC was performed in all patients on a parotid nodule. We have identified 2 groups of patients: (a) 2 cases with previous history of malignancy (acute lymphoblastic leukaemia and Hodgkin lymphoma) and (b) 3 cases without previous malignant neoplasms. In all cases, a final diagnosis of MEC was rendered. Key Messages: MEC may occur as a second malignancy in paediatric patients. FNAC is certainly a valid and accurate diagnostic tool for this type of neoplasm, even in the paediatric age, allowing the correct management of the patients.

Intra-Cystic (In Situ) Mucoepidermoid Carcinoma: A Clinico-Pathological Study of 14 Cases. J Clin Med 2020; 9:jcm9041157. [PMID: 32325647 PMCID: PMC7231055 DOI: 10.3390/jcm9041157] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 04/13/2020] [Accepted: 04/14/2020] [Indexed: 12/20/2022] Open
Abstract
AIMS To report on the clinico-pathological features of a series of 14 intra-oral mucoepidermoid carcinomas showing exclusive intra-cystic growth. Materials and methods All mucoepidermoid carcinomas diagnosed in the period 1990–2012 were retrieved; the original histological preparations were reviewed to confirm the diagnosis and from selected cases, showing exclusive intra-cystic neoplastic components, additional sections were cut at three subsequent 200 m intervals and stained with Hematoxylin–Eosin, PAS, Mucicarmine and Alcian Blue, to possibly identify tumor invasion of the adjacent tissues, which could have been overlooked in the original histological preparations. Additionally, pertinent findings collected from the clinical charts and follow-up data were analyzed. Results We identified 14 intraoral mucoepidermoid carcinomas
treated by conservative surgery and with a minimum follow up of five years. The neoplasms were located in the hard palate (nine cases), the soft palate (two), the cheek (two) and the retromolar
trigone (one). In all instances, histological examination revealed the presence of a single cystic space, containing clusters of columnar, intermediate, epidermoid, clear and mucous-producing cells, the latter exhibiting distinct intra-cytoplasmic mucin production, as confirmed by PAS, Mucicarmine and Alcian Blue stains. The cysts were entirely circumscribed by fibrous connective tissue, and no solid areas or infiltrating tumor cell clusters were detected. Conservative surgical resection was performed in all cases, and no recurrences or nodal metastases were observed during follow up. Conclusions Mucoepidermoid carcinomas showing prominent (>20%) intra-cystic proliferation currently are considered low-grade tumors. In addition, we also unveil the possibility that mucoepidermoid
carcinomas, at least in their early growth phase, may display an exclusive intra-cystic component and might be considered as in situ carcinomas, unable to infiltrate adjacent tissues and metastasize.

Abstract
Objective: Our goal was to evaluate the prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in pediatric patients with parotid cancer. Materials and Methods: Pediatric patients with primary parotid cancer were retrospectively enrolled from several clinical centers. The associations between the clinical-pathologic variables and NLR and the prognostic significance of NLR for recurrence-free survival (RFS) and disease-specific survival (DSS) were analyzed. Results: A total of 123 patients were included. The mean NLR was 2.51 and ranged from 1.7 to 6.1. The tumor stage and disease grade were significantly related to NLR. In patients with NLR < 2.51, the 10-year RFS rate was 97%, and in patients with NLR ≥ 2.51, the 10-year RFS rate was 84%; the difference was significant (p = 0.016). In patients with NLR < 2.51, the 10-year DSS rate was 98%, and in patients with NLR ≥ 2.51, the 10-year DSS rate was 83%; this difference was also significant (p = 0.035). Further Cox model analysis confirmed the independence of NLR in predicting the RFS and DSS rates. Conclusions: NLR is significantly associated with prognosis in pediatric patients with parotid cancer.
