Synchronous benign and malignant tumours in the ipsilateral parotid gland are rare. We present a case of pleomorphic adenoma and oncocytic carcinoma in the same parotid gland. Clinicians should be aware of the possibility of such synchronous multiple tumours, and that careful dissection and palpation during operation are important to diagnose them.

OBJECTIVES: Angiogenesis underlies tumour growth and metastasis through hepatocyte growth factor (HGF), epithelial growth factor (EGF), and vascular endothelial growth factor (VEGF). The aim of this study was to determine the levels of VEGF, EGF, HGF, HGFR (hepatocyte growth factor receptor), and SRSF1 (serine-rich protein splicing factor-1) in patients with parotid gland tumours and in healthy controls via ELISA in parotid saliva. Immunohistochemical expression of anti-angiogenic isoform of VEGF165 b subunit, VEGFR1, VEGFR2, and microvessel density (CD34) were assessed in the tumour tissue and in the non-tumorous surrounding margins...

RATIONALE: Pleomorphic adenoma, the most common tumor of the salivary glands, is usually benign. It is well known, however, that pleomorphic adenomas occasionally undergo malignant transformation to carcinoma ex pleomorphic adenoma and can metastasize. More rarely pleomorphic adenomas can metastasize without histological malignant transformation. We herein report an unusual case of pleomorphic adenoma with multiple metastases comprehensively demonstrated on F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT)...

A 56-year-old man who was recently diagnosed with a carcinoid tumor of the os petrosum was referred for a Ga-DOTA-TOC PET/CT scan. Besides the moderately increased Ga-DOTA-TOC accumulation in the carcinoid tumor, the scan showed strongly increased and focal Ga-DOTA-TOC uptake in an additional lesion in the right parotid gland. The markedly different Ga-DOTA-TOC avidity suggested a different etiology, and histological examination demonstrated a pleomorphic adenoma.

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...

OBJECTIVES: Ultrasound is the method of choice for preoperative evaluation of tumors of the parotid glands. However, existing methods do not allow for clear differentiation between the most common benign tumors and malignant tumors. The aim of our study was to evaluate if acoustic radiation force, Virtual Touch Quantification (VTQ) elastography helps to improve the preoperative evaluation of parotid masses. METHODS: We investigated the parenchyma of 102 parotid glands, fourteen lymph nodes of healthy volunteers and 51 tumors of the parotid gland via ultrasound, color Doppler ultrasound and VTQ...

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...

Pleomorphic adenoma (PA) of the submandibular gland is known to have a very low recurrence rate. The aim of this study was to investigate the histopathological and capsular characteristics of submandibular gland PA, looking for any differences between submandibular PA and the reported data for PA of the parotid gland as possible explanation for its low recurrence rate. We reviewed 72 submandibular gland PAs resected at our center between 2000 and 2016. Patient age ranged from 14 to 77 years (mean, 47.2). At least follow (range, 12 to 170 months; mean, 82), none of the 72 patients developed a local recurrence...

Tumor-induced osteomalacia is a rare paraneoplastic syndrome, usually caused by small benign mesenchymal tumors. The tumors most arise within the extremities, whereas occurrence within the parotid gland is quite rare. A 54-year-old woman who presented with bone pain and muscle weakness for 2 years was clinically suspected of having tumor-induced osteomalacia. A Ga-DOTANOC PET/CT was performed for localization of the causative tumor. The images demonstrated intense radiotracer accumulation in a soft tissue nodule in deep lobe of the right parotid gland...

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...
