Myoepithelial cells (MECs) are considered to be a key participant in most salivary gland diseases, particularly tumors. MECs structurally resemble both epithelial cells and smooth muscles. Diagnostic dilemmas caused are due to inadequacy of characterizing the wide spectrum of morphologic and immunologic features which are different for both normal and neoplastic MECs. This article discusses the development, functions and structure of both normal and neoplastic MECs, their staining properties and differences in the morphologic and immunophenotypic properties of the MEC in detail. It also describes the role of MEC in pathogenesis and morphogenesis of various nonneoplastic and neoplastic salivary gland lesions and thereby are responsible for the myriad histopathology of salivary gland tumors.

Objective: To evaluate the diagnostic accuracy of 18F-FDG-PET/CT compared to conventional imaging modalities (CIM) to detect recurrence of primary salivary gland cancers (SGCs).
Data Sources: Review performed on December 26, 2024, using Embase, CINHAL, MEDLINE, and PubMed.
Review Methods: Two blinded reviewers selected studies reporting diagnostic accuracy of PET/CT in identifying locoregional recurrence and/or metastasis in patients with SGCs.
Odontogenic cutaneous fistulas are abnormal connections between the oral cavity and skin, often mistaken for skin infections. They typically result from dental infections but may also arise from salivary gland issues, tumors, or congenital anomalies. Accurate diagnosis is essential to prevent complications like infection, osteomyelitis, and discomfort.

Backgroud: Salivary duct carcinoma (SDC) is a rare and aggressive malignancy with a generally dismal prognosis and no standard of care established, despite a known association with epidermal growth factor receptor 2 (HER2) and androgen receptor (AR) over-expression.
Case: We report the case of a 64-year-old female with extra- and intracranial metastases of SDC with evidence of AR and HER2 overexpression. After progression on first line chemotherapy, was administered neratinib, a pan-Erb2 receptor tyrosine kinase inhibitor.

Objective: Submandibular salivary gland inflammation has been suggested as one of the mechanisms underlying impaired salivary secretion associated with sleep deprivation (SD). However, whether the salivary inflammatory response occurs to the same extent in paradoxical sleep deprivation with or without sleep recovery remains unknown. This study evaluated the extent to which inflammation influences salivary impairments associated with paradoxical sleep deprivation with or without sleep recovery.

Pleomorphic adenoma (PA) is the most common salivary gland tumor. PAs are characterized by chromosomal rearrangements of 8q12 and 12q14-15, leading to gene fusions involving the PLAG1 and HMGA2 oncogenes. Here, we performed the first comprehensive study of the transcriptomic and gene fusion landscape of 38 cytogenetically characterized PAs.
