Effects of region of interest sizes on apparent diffusion coefficient measurements of pleomorphic adenoma, Warthin tumor, and normal parotid parenchyma.

Quant Imaging Med Surg 2019 Apr;9(4):681-690

Department of Radiology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200011, China.

The presence of two histologically distinct lesions within the same salivary gland is rare. The majority of lesions detected in salivary glands are benign and unifocal. Ultrasound scans and MRI imaging may not detect separate lesions that are in close proximity and this presents a challenge for radiologists and surgeons in the diagnosis of salivary gland lesions.

Ossified Carcinoma Ex Pleomorphic Adenoma in accessory lobe of parotid gland: Complexity in clinical, imaging and histologic diagnosis and minimally invasive surgery.

Oral Oncol 2019 05 7;92:95-98. Epub 2019 Mar 7.

Maxillofacial Surgery Unit, Department of Maxillo-Facial Surgery, University of Naples "Federico II", Naples, Italy. Electronic address:

Carcinoma ex pleomorphic adenoma is not common among malignant salivary tumors and an accessory lobe of parotid gland tumor with a carcinoma ex pleomorphic adenoma histology is even rarer. Management of these tumors include a high index of suspicion, good understanding of the anatomy and a meticulous surgical access. The exceptional localization of an ossified Carcinoma ex Pleomorphic Adenoma in the accessory lobe of the parotid gland, never reported to date in the literature, has prompted us to report this case to stress the challenging difficulties related to clinical and histologic diagnosis and to analyze a minimally invasive intraoral approach.

Clin Hemorheol Microcirc 2018 ;70(4):457-466

Department of Radiology, Ludwig-Maximilians-Universität München, Munich, Germany.

Background: Ultrasound is the method of choice for preoperative evaluation of masses of the parotid glands. However, existing methods do not allow for definite differentiation between the most common benign and malignant tumors.

Objective: Thus, we evaluated the benefits of Virtual Touch Quantification (VTQ) and Virtual Touch imaging quantification (VTIQ) for improving preoperative evaluation of parotid tumors. Read More

Surgical treatment results of parapharyngeal space tumors: a report of 22 cases.

Otolaryngol Pol 2018 May;72(4):9-16

Medical University of Warsaw Otolaryngology Depatment.

Introduction: Parapharyngeal space (PPS) is the anatomical area lateral to the upper pharynx and clinically important due to PPS tumors. They account for less than 1% of head and neck neoplasms. Both benign and malignant neoplasms may arise there and typical for this localization is diversity of histological origin. Read More

Increased incidence of Warthin tumours of the parotid gland: a 42-year evaluation.

Eur Arch Otorhinolaryngol 2018 Oct 18;275(10):2593-2598. Epub 2018 Aug 18.

Department of Otorhinolaryngology and Head and Neck Surgery, Brandenburg Medical University-Theodor Fontane, Campus Ruppiner Kliniken, Fehrbelliner Strasse 38, 16816, Neuruppin, Germany.

Aim: To evaluate the frequency of Warthin tumours among parotid neoplasms over the past 42 years in a population in rural Germany and to identify potential risk factors.

Trastuzumab Emtansine for the Treatment of HER-2 Positive Carcinoma Ex-pleomorphic Adenoma Metastatic to the Brain: A Case Report.

Front Oncol 2018 24;8:274. Epub 2018 Jul 24.

Department of Radiation Oncology, American University of Beirut, Beirut, Lebanon.

Carcinoma Ex-pleomorphic adenoma is a malignant transformation of the common benign neoplasm of the salivary glands, "pleomorphic adenoma." Only two cases were ever reported with brain metastases, with absence of good evidence guiding management of such cases. A 61-year-old woman presenting with facial paralysis was found to have carcinoma ex-pleomorphic adenoma of the parotid gland. Read More

Diffuse Neurofibroma in a Patient with Unknown History of NF1.

Case Rep Otolaryngol 2018 10;2018:8768472. Epub 2018 Jun 10.

Al-Sabah Hospital, Ministry of Health, Kuwait City, Kuwait.

Malignant peripheral nerve sheath tumor (MPNST) is a rare disease in the parotid gland with a poor prognosis in most cases. The disease most often develops in the setting of neurofibromatosis type 1 (NF1) but can also occur sporadically. Herein, we report a rare case of MPNST in the parotid gland, in a patient with no previous history of NF1. Read More

Pseudo-continuous arterial spin labeling MR images in Warthin tumors and pleomorphic adenomas of the parotid gland: qualitative and quantitative analyses and their correlation with histopathologic and DWI and dynamic contrast enhanced MRI findings.

Neuroradiology 2018 Aug 2;60(8):803-812. Epub 2018 Jul 2.

Division of Surgical Pathology, University of Fukui Hospital, 23-3 Matsuoka-Shimoaizuki, Eiheiji-cho, Fukui, 910-1193, Japan.

Purpose: We investigated the correlation between tumor blood flow (TBF) and histopathologic features of Warthin tumors (WTs) and pleomorphic adenomas (PAs) to determine the TBF in the differential diagnosis of these tumors and evaluated how well pCASL-MRI can differentiate PAs from WTs compared to conventional MRI.

Methods: The ADC, time intensity curve (TIC) pattern of dynamic contrast enhancement, and pCASL (visual assessment and TBF of the MR images of 10 WTs and 13 PAs) were reviewed. We compared the pCASL and ADC or TIC patterns in WT and PA images. Read More

Synchronous pleomorphic adenoma and oncocytic carcinoma in the ipsilateral parotid gland.

Br J Oral Maxillofac Surg 2018 09 20;56(7):629-631. Epub 2018 Jun 20.

Department of Otolaryngology-Head and Neck Surgery, Chonnam National University Medical School & Chonnam National University Hwasun Hospital, Hwasun, South Korea.

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. Read More

Metastasizing pleomorphic adenoma in the multiple organs: A case report on FDG-PET/CT imaging.

Medicine (Baltimore) 2018 Jun;97(23):e11077

Department of Pathology, The Cancer Institute Hospital of JFCR, Tokyo, Japan.

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. Read More

68Ga-DOTA-TOC Uptake in Pleomorphic Adenoma.

Clin Nucl Med 2018 Jul;43(7):524-525

From the Department of Radiology and Nuclear Medicine and.

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. Read More

Department of Magnetic Resonance Imaging, the First Affiliated Hospital of Zhengzhou University, Zhengzhou 450052, China.

To investigate the diagnostic value of RESOLVE DWI in the evaluation of benign and malignant epithelial tumors of parotid gland. A total of 106 patients in the First Affiliated Hospital of Zhengzhou University with epithelial tumors of parotid gland confirmed by pathology from July 2015 to October 2017 were retrospectively analyzed. All patients underwent preoperative routine MRI and RESOLVE DWI, the ADC average values were calculated, test were used to compare the ADC values of benign and malignant epithelial tumors of parotid gland.
