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 Mar 7. 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.

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

Usefulness of a Novel Ultrasonographic Classification Based on Anechoic Area Patterns for Differentiating Warthin Tumors from Pleomorphic Adenomas of the Parotid Gland.

Yonago Acta Med 2017 Dec 5;60(4):220-226. Epub 2018 Feb 5.

Division of Otolaryngology, Head and Neck Surgery, Department of Sensory and Motor Organs, School of Medicine, Tottori University Faculty of Medicine, Yonago 683-8503, Japan.

Background: Ultrasonographic homogeneity is an important differential finding between Warthin tumor and pleomorphic adenoma, two types of benign parotid gland tumors, with the former likely to be heterogeneous and the latter homogeneous. However, differences in the performance of ultrasound machines or the homogeneity cut-off level affect the judgment of ultrasonographic homogeneity. Therefore, in this study, we adopted a novel system for classifying the composition of tumors via ultrasonography, using anechoic area as a substitute for differences in homogeneity to differentiate between Warthin tumors and pleomorphic adenomas.
