Epithelial-myoepithelial carcinoma (EMC) is a malignant salivary gland neoplasm comprised of a biphasic arrangement of inner luminal ductal cells and outer myoepithelial cells. Adenoid cystic carcinoma (AdCC) is also a biphasic tumor comprised of ductal and myoepithelial cells, but these components tend to be arranged in a more cribriform pattern. The occurrence of "hybrid carcinomas" that show mixed patterns of EMC and AdCC raises questions about the relationship of these morphologically overlapping but clinically distinct tumors...

BACKGROUND: Fine-needle aspiration (FNA) is routinely performed to evaluate salivary gland lesions, and provides valuable information regarding the cytomorphologic features of the lesions. Occasionally, there are overlaps between benign and malignant conditions due to heterogeneity of the cell types, metaplastic changes, and sampling issues. Herein, the authors present a retrospective study of diagnostic pitfalls in salivary gland cytology and the simulating conditions. METHODS: A 20-year retrospective review (1995-2015) of medical records was performed searching for the cytology reports of patients who underwent FNA of the salivary gland with the words "amendment" or "revision...

Pleomorphic adenoma, also known as tumor mixtus, is one of the most common types of benign neoplasm of the salivary gland, which presents as a slow growing, painless tumor. Major salivary glands are the typical localization of this neoplasm. It rarely undergoes malignant transformation, however may recur locally post resection. In this study, we present the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine between 2004 and 2015 due to pleomorphic adenoma...

Salivary gland neoplasms are a morphologically heterogenous group of lesions that are often diagnostically challenging. In recent years, considerable progress in salivary gland taxonomy has been reached by the discovery of tumor type-specific fusion oncogenes generated by chromosome translocations. This review describes the clinicopathologic features of a selected group of salivary gland carcinomas with a focus on their distinctive genomic characteristics. Mammary analog secretory carcinoma is a recently described entity characterized by a t(12;15)(p13;q25) translocation resulting in an ETV6-NTRK3 fusion...

Clear cell carcinoma (CCC) is a low-grade malignancy that commonly arises in minor salivary glands of the oropharynx and other sites. EWSR1-ATF1 gene fusions seem to be specific for this salivary neoplasm. Testing for EWSR1-ATF1 has expanded the histologic spectrum of CCC. As one important example, many CCCs have a predominantly squamous phenotype with few clear cells, a finding that can cause confusion with squamous cell carcinoma (SqCC). P16 immunohistochemical staining to determine human papillomavirus (HPV) status has become standard practice for all oropharyngeal carcinomas showing squamous differentiation...

BACKGROUND: Fine-needle aspiration (FNA) cytology is well accepted as a safe, reliable, minimally invasive, and cost-effective method for the diagnosis of salivary gland lesions. Salivary gland neoplasms are often difficult to diagnose because of morphologic heterogeneity and a variety of epithelial metaplastic changes. Hence, a number of salivary gland FNA specimens yield indeterminate results. For indeterminate FNA specimens, the suspicious-for-malignancy (SFM) category is used when a specific neoplasm falls short in quantity or quality for the criteria for malignancy...

Mesenchymal neoplasms of salivary gland including adipocytes are relatively uncommon entity classified as monophasic and biphasic. Sialolipoma, a biphasic mesenchymal salivary gland neoplasm, with a prominent vascularity designated as sialoangiolipoma (SAL) is a recently discussed entity with debates on the hamartomatous nature of the lesion. We have endorsed the hamartomatous nature through evaluating the immunoexpression of Ki-67 and endoglin in SAL in hard palate of a 60-year-old patient. To the best of our knowledge, this would be the second case of SAL in hard palate in a global platform...

Salivary gland neoplasms are a relatively uncommon disease, with nearly one case per 100.000 adults estimated per year and an overall incidence of 1% of all neoplasms. The benign neoplasms are majority and the prognosis depends on the histologic type, grade, localization, soft tissue infiltration, regional and distant metastasis. The main treatment is surgery with caution to facial nerve in the major salivary glands, followed by radiotherapy and chemotherapy in selected cases. The objective of this review is to provide the lector an historic approach about salivary gland diseases treatment, with special attention to the parotid neoplasms and its peculiarities associated to those who studied these glands in their history course...

Warthin tumor is the second most common salivary gland neoplasm. It occurs more commonly in males than in females. Malignant transformation in Warthin tumor is a rare but well-recognized phenomenon; however, the development or presentation of lymphoma in a Warthin tumor is rare. An 80-year-old man presented with painless mass of the right parotid gland of 2 years duration with recent ulceration of the overlying skin and right cervical lymphadenopathy underwent a surgical resection of parotid mass and biopsy of the periglandular lymph nodes...

BACKGROUND: Lymphoid enhancer binding factor 1 (LEF-1) has recently been reported as a potential immunohistochemical (IHC) marker for basal cell adenoma (BCA) and other salivary gland tumors, which may contribute to an increased accuracy in differentiating basaloid salivary gland neoplasms. We evaluated the utility of LEF-1 in fine needle aspiration (FNA) and resection specimens to distinguish pleomorphic adenoma (PA), BCA, basal cell adenocarcinoma (BCAC), and adenoid cystic carcinoma (ACC) as well as in non-neoplastic salivary gland (NNSG)...

BACKGROUND: Fine needle aspiration (FNA) is widely used in the diagnosis of salivary gland lesions. Salivary gland FNAs are often difficult to diagnose because of morphologic heterogeneity, a small but significant number of the FNAs yield "atypical" diagnosis. However, systematic evaluation of the risk of malignancy (ROM) of the atypical diagnoses across institutions and the variability of ROM among institutions are still lacking. METHODS: Salivary gland FNAs from five tertiary medical centers of United States, Europe and China were reviewed...

Dental and immunological features of the influence of various prosthetic structures of orthopedic prostheses on tissues and organs of the maxillofacial region were evaluated by the parameters of expression of oral fluid biomarkers. Healthy people without tumor and somatic diseases and patients with neoplasms of maxillofacial area in need of dental rehabilitation were examined before and in 2 weeks and 3 months after treatment. Certain regularities in the reaction of biomarkers to orthopedic prostheses were observed: a decrease in activity of MMP-2 and MMP-8 and their inhibitors or an increase in MMP-9; an increase in activity of biomarkers at early terms and a decrease in delayed terms after prosthetics...

Oral cancer is a malignant neoplasm that occurs in the oral cavity. Squamous cell carcinoma accounts for over 90%of the oral cancers, and others include adenocarcinoma derived from minor salivary gland, sarcoma, malignant lymphoma and metastatic cancer. The number of oral cancer patients in Japan is about 3-times higher than the current number. Age-adjusted male-to-female ratio is 3:2, which is higher in males than in females. Of oral cancers, tongue carcinomas accounts is the most common and accounts for 40%of oral cancers...

Salivary duct carcinoma (SDC) is an uncommon, aggressive malignant neoplasm histologically resembling high-grade mammary ductal carcinoma. SDC can arise de novo or ex pleomorphic adenoma. To clarify the correlation of biomarker immunoprofile with clinicopathological findings and clinical outcome of SDC, we conducted immunohistochemistry for EGFR, HER2, HER3, AR, CK5/6, p53, and Ki-67, along with HER2 fluorescence in situ hybridization in 151 SDCs. SDCs ex pleomorphic adenoma more commonly overexpressed EGFR, HER2, HER3, and Ki-67 than de novo SDCs (P = 0...

Accessory parotid gland (APG) is seen in around 21%-56% of individuals. Tumors of accessory parotid are uncommon with an incidence rate of 1%-8% of all parotid tumors. Ductal carcinoma of APG is rare, so no reported incidence was seen in the literature. However, salivary gland ductal carcinoma is reported to be 1% of all salivary gland neoplasms. We report here a case of salivary duct carcinoma of APG. Clinical presentation, investigation, and management are discussed. A 69-year-old female presented with a history of the left cheek progressive swelling of 6 years' duration...

BACKGROUND: The role fine-needle aspiration (FNA) in the diagnosis of salivary gland lesions has evolved over the years. Although clinical and radiological parameters help to narrow the differential diagnosis the tissue diagnosis still remains the gold standard. MATERIALS AND METHODS: This study is from January 2013 to December 2015 in our Department of Pathology where 170 salivary gland lesions were aspirated. The aim of the present study was to analyze adequacy rate in relation to the size of lesion and to evaluate varied cytological spectrum of salivary gland lesions with emphasis on differential diagnosis and to correlate cytological diagnosis with age, gender and anatomical site...

Miguel Rito, Isabel Fonseca
Salivary gland tumor classification encompasses a vast list of benign and malignant neoplasms. Their morphological diversity is recognized not only between different entities but also within individual tumors. Tumor categories as described by the World Health Organization reflect, in part, a true genetic heterogeneity (e.g., translocations involving CRTC1 and CRTC3-MAML2 genes in mucoepidermoid carcinoma and MYB-NFIB fusion in adenoid cystic carcinoma). Carcinoma ex pleomorphic adenoma shows diversity in its histological appearance, but recurrent rearrangements on PLAG1 and HMGA2 are common to its benign precursor...

Myoepithelioma is a rare salivary gland neoplasm. They most commonly affect the major and minor salivary glands with the parotid gland being the most common, approximately 40%. Only 1% of all salivary gland neoplasms are myoepitheliomas. Myoepithelioma is usually a benign tumor arising from neoplastic myoepithelial or basket cells which are found between the basement membrane and the basal plasma membrane of acinar cells. They also contain multiple cellular elements. We present a case of a 73-year-old female with myoepithelioma of the parotid gland, an extremely rare neoplasm...
