Adenoma

Pleomorphic adenoma of the frontal sinus masquerading as a mucocele

December 14, 2015  |  Yok Kuan Chew, MBBS; Sushil Brito-Mutunayagam, MS; Aun Wee Chong, MS; Narayanan Prepageran, FRCS; Patricia Ann Chandran, MPath; Baharudin Khairuzzana, MS; Omkara Rubini Lingham, MS

Abstract

Pleomorphic adenoma is the most common type of benign salivary gland tumor. It can also be found in the larynx, ear, neck, and nasal septum. It is rarely found in the maxillary sinus, and it has never been reported in the frontal sinus. We report a case of pleomorphic adenoma...

Soft palate mass

Although pleomorphic adenomas are mostly benign, they have the potential to grow very large yet remain asymptomatic.

Endoscopic transnasal transsphenoidal transtuberculum sellae extradural approach to suprasellar pituitary lesions: A case report

September 21, 2015  |  Tapan Nagpal, MS

Abstract

Pituitary adenomas are benign tumors that arise within the anterior lobe (the adenohypophysis) of the pituitary gland in the sella turcica. As they grow, they can extend through the pituitary stalk and into the suprasellar compartment. The surgical management of these adenomas...

A rare case of pleomorphic adenoma of the nasal septum

June 5, 2015  |  Tejinder Singh Anand, MS, PhD; Gautam Bir Singh, MS; Sunil Garg, MS; Garima Yadav, MBBS; Anita Nangia, MD

Pleomorphic adenomas of the nasal cavity differ from those found elsewhere in that they have more myoepithelial cells and little or no stromal component.

Parathyroid localization using 4D-computed tomography

April 28, 2015  |  Darrin V. Bann, PhD; Thomas Zacharia, MD; David Goldenberg, MD, FACS; Neerav Goyal, MD, MPH

To decrease the risk of iatrogenic cancers associated with 4D-CT, several groups have used one- or two-phase imaging protocols to identify parathyroid adenomas.

A transoral surgical approach to a parapharyngeal-space pleomorphic adenoma

October 18, 2014  |  Christopher Schutt, MD; Joehassin Cordero, MD, FACS

Abstract

It is relatively difficult to gain surgical access to pleomorphic adenomas of the parapharyngeal space. Since the lateral border is the mandible, gaining access to them can put several important neurovascular structures at risk. A number of surgical approaches have been...

Transoral approach to a deep-lobe parotid tumor

October 18, 2014  |  Lyndon Gonzalez, BS; Alex Fernandez, MS; Belinda Mantle, MD

Because of their location in this potential space, parapharyngeal tumors tend to be asymptomatic and remain undetected for a long time.

Parathyroid adenoma

July 14, 2014  |  Lester D.R. Thompson, MD

Most of these lesions are identified in glands within their usual anatomic location instead of in an ectopic or supernumerary site.

Parathyroid adenoma in a woman with secondary hyperparathyroidism

May 8, 2014  |  Darrin V. Bann, PhD; Neerav Goyal, MD, MPH; David Goldenberg, MD, FACS

For surgical treatment of secondary hyperparathyroidism, a common approach is the removal of three and one-half glands (subtotal parathyroidectomy), leaving the remaining half gland in place with an intact vascular pedicle. Alternatively, a total parathyroidectomy may be performed, and one-...

Massive pleomorphic adenoma of the parotid gland: Surgical considerations

May 8, 2014  |  Alex Fernandez, MS; Ryan F. Osborne, MD, FACS; Jason S. Hamilton, MD, FACS

Preservation of the facial nerve and its branches requires special consideration when dealing with a large parotid mass. The traditional approach of anterograde dissection of the facial nerve proves ineffective in patients with large lesions that effectively obstruct the field of view and...

A rare cause of submandibular swelling in a 12-year-old child: Pleomorphic adenoma

January 21, 2014  |  Puneet S. Braich, MD, MPH; Shohan Shetty, MD; Archana Lingampally, MBBS; Michael S. Ajemian, MD, FACS; Mahesh H. Bhaya, MBBS, FACS

Abstract

Pleomorphic adenoma is rare in pediatric populations, where viral and congenital problems are the usual culprits responsible for submandibular masses. We report the case of a 12-year-old child who presented with a painless right submandibular mass that had developed over the...

Massive calcification in a pleomorphic adenoma: Report of an unusual presentation

January 24, 2013  |  Luiz O.M. Coelho, MD; Sergio E. Ono, MD; Arnolfo de Carvalho Neto, PhD; Christiane S. Kawasaki, MD; Luciano V. Sabóia, MD; Maria F. Soares, MD

Abstract

We report a case of histology-proven pleomorphic adenoma of the parapharyngeal space in a 20-year-old man. This case was unusual in that a massive amount of dystrophic calcification was scattered throughout the tumor. The patient underwent successful surgical resection, and he...
