Distribution and Frequency of Salivary Gland Tumours: An International Multicenter Study.

Head Neck Pathol 2022 May 27. Epub 2022 May 27.

Unit of Oral and Maxillofacial Pathology, School of Clinical Dentistry, University of Sheffield, Sheffield, S10 2TA, UK.

Background: Salivary gland tumours (SGT) are a relatively rare group of neoplasms with a wide range of histopathological appearance and clinical features. To date, most of the epidemiological studies on salivary gland tumours are limited for a variety of reason including being out of date, extrapolated from either a single centre or country studies, or investigating either major or minor glands only.

Methods: This study aimed to mitigate these shortcomings by analysing epidemiological data including demographic, anatomical location and histological diagnoses of SGT from multiple centres across the world. Read More

Mucoepidermoid carcinoma - A common neoplasm at an unusual site, mimicking a benign cyst on cytology: Diagnostic pitfall!

J Oral Maxillofac Pathol 2022 Feb 28;26(Suppl 1):S30-S33. Epub 2022 Feb 28.

Department of Pathology, Kasturba Medical College, Manipal, Karnataka, India.

Mucoepidermoid carcinoma (MEC) is known to be a relatively common neoplasm of the major and minor salivary glands that can secondarily involve skin. The clinical manifestations, diagnostic cytology and histopathology of MEC presenting as a clinically benign periauricular cystic nodule have been analyzed. The challenge of accurate diagnosis can be illustrated by the fact that initially, on cytology, this tumor was misdiagnosed as a benign epidermal inclusion cyst due to the presence of mucin-filled cells which were misinterpreted as cyst macrophages.

Clear Cell Neoplasms of Salivary Glands: A Diagnostic Challenge.

Adv Anat Pathol 2022 Jul 7;29(4):217-226. Epub 2022 Mar 7.

International Head and Neck Scientific Group, Padua, Italy.

This review focuses on the heterogenous group of clear cell neoplasms of salivary glands and attempts to identify major differential diagnostic features. Within the head and neck region, clear cells are found most commonly in salivary gland tumors, but may also be seen in tumors of squamous or odontogenic epithelial origin, primary or metastatic carcinomas, benign or malignant melanocytic lesions, or benign or malignant mesenchymal tumors. Clear cells occur fairly commonly among a wide variety of salivary gland neoplasms, but mostly they constitute only a minor component of the tumor cell population. Read More

F-fluorodeoxyglucose PET/Computed Tomography: Head and Neck Salivary Gland Tumors.

PET Clin 2022 Apr 26;17(2):249-263. Epub 2022 Feb 26.

Department of Radiology, Mayo Clinic, Rochester, MN, USA; Department of Neurology, Mayo Clinic, Rochester, MN, USA.

Salivary gland tumors (SGTs) are a heterogeneous group of neoplasms arising from the 3 pairs of major salivary glands (parotid, submandibular, and sublingual) or numerous minor salivary glands located throughout the oral cavity. This review discusses the role of PET/computed tomography (CT) in evaluation of SGTs, including staging, restaging, prognostication, and response assessment. 18F-fluorodeoxyglucose (FDG) PET/CT is useful for staging and restaging malignant SGTs and offers important prognostic information in these patients.

Department of Cell, Developmental & Cancer Biology, Oregon Health and Science University, Portland, OR 97239, USA.

Salivary gland tumors are diverse neoplasms, likely reflecting differences in the tissue- and cell-of-origin. 80%-90% of tumors arising in the sublingual gland (SLG) are malignant, whereas the other major glands often form benign tumors. Owing to the lack of experimental models to explore the etiology of salivary gland tumors, the cellular and molecular bases of malignancy remain unknown. Read More

Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Ryukyu University, Nishihara, Okinawa 903-0215, Japan.

Mucoepidermoid carcinomas (MECs) are rare head and neck malignant tumours that were originally considered to be benign. It has been estimated that ~20% of MECs in the major salivary glands, such as the parotid gland, and 50% in the several minor salivary glands found in the oral cavity, are malignant. The diagnosis of MECs is mainly based on ancillary and immunohistochemistry testing. Read More

Parotid pleomorphic and non-pleomorphic adenomas: a mono-institutional series of 512 patients.

Eur Arch Otorhinolaryngol 2022 May 5;279(5):2543-2551. Epub 2021 Aug 5.

Unit of Otorhinolaryngology-Head and Neck Surgery, ASST Spedali Civili, Brescia, Italy.

Purpose: Pleomorphic adenoma (PA) is the most common benign parotid tumor, with a well-known propensity to recur. Many factors have been advocated as prognostic, but there is no consensus on how they affect local control. We studied how PA recurrence-free survival (RFS) may be affected by the most relevant risk factors in a time-to-event analysis, comparing them with those observed in a population of non-PA (NPA).

HMGA2-WIF1 Rearrangements Characterize a Distinctive Subset of Salivary Pleomorphic Adenomas With Prominent Trabecular (Canalicular Adenoma-like) Morphology.

Am J Surg Pathol 2022 02;46(2):190-199

Department of Pathology, Charles University, Faculty of Medicine in Plzen.

Most of salivary gland neoplasms (benign and malignant) are characterized by recurrent gene fusions. Pleomorphic adenoma (PA), the most frequent salivary gland tumor, is driven by chromosomal rearrangements involving PLAG1 mapped to 8q12 and HMGA2 mapped to 12q13-15 in most cases. Multiple fusion partners have been identified including CTNNB1, FGFR1, LIFR, CHCHD7 and TCEA for PLAG1 fusions and NFIB, WIF1 and FHIT for HMGA2 fusions. Read More

Sebaceous Lymphadenoma: Radiology-Pathology Correlation.

Head Neck Pathol 2021 Jun 4;15(2):593-598. Epub 2021 Jan 4.

Departments of Pathology and Laboratory Medicine, Emory University, Atlanta, GA, 30308, USA.

Sebaceous lymphadenoma is a rare salivary gland neoplasm most commonly occurring in the sixth to eighth decades of life. Cross sectional imaging typically demonstrates a multicystic expansile mass, most commonly occurring in the parotid gland, where the radiographic differential diagnosis would include Warthin tumor in this location and age group. Ultimately, the diagnosis is confirmed with the histopathologic findings of tubuloglandular epithelial profiles with sebaceous differentiation and cystic change set within a dense, benign lymphocytic infiltrate.
