RATIONALE: Primary mucoepidermoid carcinoma (MEC) of the esophagus is a rare type of malignant neoplasm. Its morphology resembles that of MEC of the salivary glands. It is characterized by a diffuse mixture of squamous and mucus-secreting glandular carcinoma cells. Due to the low incidence of esophageal MEC, the biological behavior and treatment of this tumor have not been well studied. PATIENT CONCERNS: In this case report, we describe a case of a 59-year-old man who presented with difficulty in swallowing...

BACKGROUND: A few cases of oral schwannomas in paediatric patients have appeared in the literature so far; however, there are no studies focusing solely on paediatric oral schwannomas. The aim of this study is to report a case of palatal schwannoma in a young female patient and review the pertinent literature on oral schwannomas in paediatric patients. CASE REPORT: A 12-year-old girl presented with a growing swelling of 2 weeks duration on the hard palate. With a provisional diagnosis of a salivary gland neoplasm an incisional biopsy was performed under local anesthesia and the histologic examination disclosed an Antony A type schwannoma...

Basaloid squamous cell carcinoma with spindle cell component is an uncommon aggressive variety of squamous cell carcinoma with only a few reported cases in literature. Histologically a combination of basaloid squamous cell carcinoma and spindle cell squamous cell carcinoma is appreciated and immunohistochemistry serves a role in differentiation from malignant neoplasms of salivary gland or neuro-endocrine origin. Prime treatment modality is combination of surgery and external beam radiotherapy. A case of basaloid squamous cell carcinoma with proliferation of bizarre mesenchymal component is being reported here with an updated literature review...

BACKGROUND: Fine-needle aspiration (FNA) is widely accepted in the preoperative management of salivary gland lesions. The proposed Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) aims to standardize reporting terminology. Studies regarding the risk of malignancy (ROM) for the proposed categories continue to evolve. The current retrospective study applied the MSRSGC to assess ROM for salivary gland lesions and focused on the "indeterminate" categories. METHODS: A total of 627 salivary gland FNA specimens obtained from 2011 through 2016 were retrieved, with follow-up available for 373 cases...

Salivary adenoid cystic carcinoma is a very common malignant neoplasm in the salivary glands. One of the most important features of salivary cystic carcinoma is perineural invasion, which renders its complete removal is very difficult through clinical surgery. Consequently, tumor recurrence occurs easily after clinical surgery. Therefore, the molecular mechanisms of perineural invasion in salivary adenoid cystic carcinoma are necessary to explore. These mechanisms are reviewed in this paper.

Pleomorphic adenoma (benign mixed tumor) is the most common epithelial neoplasm of the lacrimal gland. It is usually a slow growing, well-circumscribed, mass that is identical to its salivary gland counterpart. Patients generally have an excellent prognosis for vision and long-term survival after complete surgical excision. There is a tendency to reoccur, especially if there is an incomplete excision, and rarely, malignant transformation to carcinoma ex pleomorphic adenoma can occur, which has a much poorer prognosis...

To our knowledge this is only the second reported case of a cystadenoma that arose in the mandible. These are rare benign epithelial neoplasms of the salivary gland that comprise 0.8%-6.3% of all minor tumours of the salivary gland. Because cystadenoma of the mandible is so rare, there is little evidence or guidance about management, and enucleation remains the recommended treatment. Careful histological diagnosis is important for differentiation from other morphologically similar salivary gland tumours such as a mucoepidermoid carcinoma...

The spectrum of low-grade intraductal papillary proliferations of the salivary glands is heterogenous, and reproducible morphologic diagnostic criteria have not yet been established. Recognized types are sialadenoma papilliferum, inverted ductal papilloma, and intraductal papilloma, but some lesions have been possibly included in the morphologic spectrum of cystadenoma or low-grade intraductal carcinomas. We herein present detailed morphologic, immunophenotypic, and genotypic features of 3 minor salivary gland neoplasms affecting 2 men (aged 65 and 71 y) and 1 woman (aged 78 y)...

Introduction: Salivary gland tumors are the most histologically heterogeneous group of tumors with the greatest diversity of morphologic features among their cells and tissues. The present study was aimed at assessing the validity of Ki-67, a cell proliferation marker, as a prognostic factor in benign and malignant salivary gland tumors and to study whether it is related to age, sex, anatomical site, and size of the lesion in salivary gland tumors. Materials and methods: A retrospective study consisted of benign salivary gland tumors (BSGTs) (n = 15), malignant salivary gland tumors (n = 18), and normal salivary gland parenchyma (n = 15)...

Salivary gland tumours constitute approximately 1-5% of all human neoplasms. Pleomorphic adenoma (PA) is the commonest benign neoplasm affecting the parotid gland most often (> 75%), followed by the submandibular gland (13%), then the palate (9%). Metastasising pleomorphic adenoma (MPA) is extremely rare. The effects can be severe and a reported 40% of MPA patients die with disease. This case represents the first known case in English literature of an untreated minor salivary gland PSA of the palate metastasising to an ipsilateral cervical node...

OBJECTIVE: No universally accepted classification exists for salivary gland fine-needle aspiration (FNA). The proposed Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) offers a uniform classification with management recommendations. We compared FNA diagnoses from a prior study with specific diagnoses with corresponding MSRSGC diagnoses. METHODS: One-hundred and sixty-four cases from a prior cytologic study with histologic follow-up were re-reviewed by one of the authors and assigned to one of the MSRSGC categories...

The miRNA-196a2 has shown significance in the development of various neoplasms, including head and neck squamous cell carcinoma (HNSCC). The oncogenic functionality of this miRNA is mediated via its potential to target annexin A1 mRNA, a tumor suppressor gene involved in inhibition of the NF-κB pathway. Interestingly, recent data indicate a susceptibility for aforementioned neoplasms in patients with the CC genotype vs the CT and TT genotypes of the rs11614913 SNP located within the DNA sequence of the miR-196a2 that results in elevated expression of the gene...

Mammary analog secretory carcinoma is a primary salivary gland neoplasm with histologic, immunophenotypic, and molecular features identical to those of secretory carcinoma of the breast. Similar neoplasms have now been reported to occur in various nonmammary sites including the parotid gland, submandibular gland, sinuses, lip, skin, thyroid gland, and lung. We report, to our knowledge, the first example of a primary vulvar neoplasm with pathologic features identical to secretory carcinoma of the breast and an ETV6-NTRK3 fusion...

BACKGROUND: The Milan System for Reporting Salivary Gland Cytopathology is a tiered classification scheme that includes 6 diagnostic categories. Neoplasm, which is 1 of the 6 proposed categories, consists of benign neoplasm and neoplasm of uncertain malignant potential (NUMP). NUMP is reserved for a salivary gland neoplasm without clear distinction between benign and malignant. The objective of this study was to assess the risk of malignancy (ROM) of NUMP. METHODS: A retrospective analysis was conducted on 656 salivary gland fine-needle aspiration specimens from 2010 to 2016...

NUT carcinoma (NC) represents a rare subset of highly aggressive poorly differentiated carcinomas characterized by rearrangement of the NUT (aka NUTM1, nuclear protein in testis) gene, most commonly fused to BRD4. Originally described as a mediastinal/thymic malignancy, NC has been reported at a variety of anatomic regions including the upper and lower aerodigestive tract. To date, only 7 NC cases of probable salivary gland origin have been reported. We herein describe 3 new cases (all affecting the parotid gland) in 2 women (39- and 55-y old) and 1 man (35-y old)...

Ultrasound is the preferred initial imaging modality in Europe and Asia for assessing the major salivary glands. In experienced hands, it is sensitive for a range of salivary pathologies, often diagnostic, and also a safe, cost-effective gatekeeper for further investigations as well as image-guided diagnostic biopsies and aspirations. This article reviews the scanning technique and normal sonographic anatomy of major salivary glands and overviews typical sonographic appearances of salivary pathologies, including infective and inflammatory conditions, sialolithiasis, and neoplasms...
