An increasing number of patients with parotid gland tumors have been observed in recent years. The relationship between the immune system and tumor formation is thoroughly investigated. However, newly discovered molecules offer a new insight into the pathophysiology of malignancies. It would be ideal to find an easily determinable biomarker of tumor existence, its malignant potential or a biomarker suggesting the probability of disease recurrence. Our study is the first to examine serum concentrations of IL-33 and its sST2 receptor in patients with various types of parotid gland tumors...

Centrally occurring salivary gland tumors are rare. Because of a considerable overlap between the clinical and histopathological features, this group of tumors often produces a diagnostic difficulty to the clinicians and oral pathologists. Acinic cell carcinoma (ACC) is an unusual, low-grade, malignant salivary gland tumor that represents approximately 2% of the salivary gland tumors with almost 90% arising in the parotid gland. The rest involve the submandibular and the minor salivary gland. ACC of the jaw is extremely rare and, to our knowledge, only 8 cases have been reported in the English literature...

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)...

Secretory carcinoma of the salivary glands, also known as mammary analogue secretory carcinoma, is a recently described tumor characterized by generally indolent clinical behavior and recurrent ETV6-NTRK3 fusions. However, a small subset of recent cases with high-grade histology, aggressive behavior, or alternate molecular findings are expanding the spectrum of this entity. In this case, a 59-year-old female presented with an infiltrative submandibular gland tumor that was originally classified as a high-grade acinic cell carcinoma, papillary-cystic variant...

DOG1 is an established diagnostic marker for gastrointestinal stromal tumours (GIST), but has been reported in salivary gland tumours (SGT) as an acinar and intercalated duct marker. However, its specificity and distribution is not well established. The aim of this study was to evaluate the diagnostic utility of DOG-1 expression in SGT in addition to comparing it with myoepithelial markers. Normal salivary tissue and SGT (n = 184) were examined for expression of DOG1 and a range of myoepithelial markers...

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...

Salivary gland tumors account for 3-6% of tumors of the head and neck. About 80% of salivary gland tumors occur in parotid glands. Oxidative stress (OS) is implicated in the origin, development, and whole-body effects of various tumors. There are no data on the occurrence of OS in the parotid gland tumors. The aim of this study was to ascertain if whole-body OS accompanies parotid gland tumors, based first of all on oxidative modifications of blood serum proteins and other markers of OS in the serum of the patients...

PURPOSE: Salivary gland cancers (SGC) frequently present with distant metastases many years after diagnosis, suggesting a cancer stem cell (CSC) subpopulation that initiates late recurrences; however current models are limited both in their availability and suitability to characterize these rare cells. EXPERIMENTAL DESIGN: Patient-derived xenografts (PDX) were generated by engrafting patient tissue onto nude mice from one acinic cell carcinoma (AciCC), four adenoid cystic carcinoma (ACC), and three mucoepidermoid carcinoma (MEC) cases, which were derived from successive relapses from the same MEC patient...

Salivary gland malignancies are rare tumors that comprise multiple histologic entities with diverse clinical behavior. Mucoepidermoid carcinoma is the most frequent primary salivary malignancy, followed by adenoid cystic and acinic cell carcinoma. Although most salivary malignancies are asymptomatic, presentation with a rapidly enlarging mass may be accompanied by pain, functional neurologic deficits, soft-tissue invasion, or nodal enlargement. Assessment of clinical behavior and physical exam greatly contributes to diagnostic workup...

Fine needle aspiration cytology (FNAC) is often the first investigation in the work up of salivary gland lesions. However, its diagnostic accuracy is limited by the high rates of false positives and false negatives. Usually, acinic cell carcinoma is prone to be underdiagnosed because of the cytological similarity of the tumor cells to normal acinar cells, however rarely, a predominant papillary architecture on cytology may cause confusion with adenocarcinomas. We present a case of a 45-year-old male with a painful swelling of the right parotid region...

Salivary gland tumors have a high incidence (90%) within the parotid gland. The acinic cell carcinoma (ACC) represents only 1-3% of the salivary gland tumors, most frequently affecting the parotid. The minor salivary glands rarely develop ACC and when the ACC is localized in these glands, generally, it has a less aggressive evolution. The main criterion in the diagnostic of ACC is the histological examination with the regular Hematoxylin-Eosin (HE) staining and additionally Periodic Acid-Schiff (PAS) special staining...

Acinic cell carcinoma of the parotid gland is a rare low-grade malignant neoplasm. Data on children are sparse. For the present study, the database of a tertiary pediatric medical center was reviewed for all patients with parotid gland acinic cell carcinoma diagnosed and treated between 2004 and 2013. Clinical, histologic, treatment, and outcome parameters were collected from the medical files. Four patients were identified, 3 female and 1 male, aged 13.5 to 18 years (median 15.7) at diagnosis. One patient had a family history of parotid tumor and 1 of hypothyroidism/hyperthyroidism...

AIMS: Indolent T-lymphoblastic proliferation (iT-LBP) is a non-clonal benign condition showing extrathymic proliferation of T-lymphoblasts positive for CD3, CD4, CD8, and TdT. Isolated iT-LBP has been observed, but the majority of iT-LBPs have been seen in conjunction with other disorders, including Castleman disease, hepatocellular carcinoma, follicular dendritic cell tumours, angioimmunoblastic T-cell lymphoma, myasthenia gravis, and acinic cell carcinoma (ACC). The clinical course of iT-LBP is indolent, and no therapy is usually required...

Secretory carcinoma (SC), previously described as mammary analogue secretory carcinoma (MASC), is a recently described salivary gland tumor which morphologically resembles mammary secretory carcinoma. The first description of SC/MASC, reported by Skálová et al . in 2010, was as a rare salivary carcinoma imitating secretory carcinoma of the breast. SC/MASC is a unique salivary gland tumor with morphological overlap with acinic cell carcinoma (AciCC), mucoepidermoid carcinoma (MEC), and adenocarcinoma not otherwise specified (ADC-NOS)...
