Abstract


Primary giant-cell tumor of the salivary gland is a rare lesion with an incompletely characterized histogenesis. To the best of our knowledge, only 16 cases have been previously documented in the English-language literature. We report a new case, which occurred in a 75-year-old man who presented with a parotid mass and cervical lymphadenopathy. The patient underwent a left total parotidectomy and cervical lymph node dissection. As far as we know, ours is the only reported case of a primary giant-cell tumor of the salivary gland in which the patient presented with lymph node metastasis. Because so little is known about giant-cell tumor of the salivary gland, we use the occasion of this case report to describe the cytologic, histologic, and immunohistochemical characteristics that we observed.

Use of AlloDerm implant to improve cosmesis after parotidectomy

article
Abstract
We evaluated the effectiveness and practicality of using AlloDerm, an acellular human dermal matrix graft, as an interpositional barrier in an attempt to improve the appearance of the surgical defect created by parotidectomy. We performed AlloDerm reconstruction in a series of 10 patients, and we found that normal contour was satisfactorily restored in all 10. We conclude that the use of an AlloDerm implant is a low-risk, practical option for repairing the surgical defect in postparotidectomy patients.

Toxoplasmosis lymphadenitis presenting as a parotid mass: A report of 2 cases

September 30, 2006     Ron G. Shashy, MD; Daniel Pinheiro, MD, PhD; Kerry D. Olsen, MD
article
Abstract
Toxoplasmosis manifesting as a parotid mass is rare; our review of the literature found only 6 previously reported cases. We report 2 new cases. Both patients presented with a small, mobile left parotid mass, and both were successfully treated with a diagnostic superficial parotidectomy. In both cases, the patient had been regularly exposed to cats and had recently eaten undercooked meat. When evaluating a parotid mass, otolaryngologists should be aware of the infectious causes of parotid swelling and lymphadenopathy and consider the possibility of toxoplasmosis when the history and pathologic findings are not suggestive of more common diseases.

Sarcoidosis presenting as a solitary parotid mass

article
Abstract
We describe an unusual case of sarcoidosis in which the patient presented with a discrete solitary parotid mass and no other manifestation of the disease. The diagnosis was based on the unexpected pathologic findings during examination of a superficial parotidectomy specimen. To the best of our knowledge, no such presentation has been previously reported in the English-language literature.

Polymorphous low-grade adenocarcinoma of the parotid gland

article
Abstract
Polymorphous low-grade adenocarcinoma (PLGA) of the parotid gland is rare. We describe a new case in which the patient underwent parotidectomy only to experience an extensive recurrence 2 years later. The recurrence was treated with radical surgical excision and radiation therapy, and the patient remained disease-free at 5 years of follow-up. We also review the literature on primary parotid PLGA.

Primary carcinoid tumor of the parotid gland: A case report and review of the literature

Abstract
Salivary gland tumors account for 3 to 6% of all head and neck neoplasms in adults. Some 70 to 85% of these lesions are found in the parotid. Carcinoid tumors, which represent a distinct and relatively uncommon subset of neuroendocrine tumors, are most commonly found in the gastrointestinal tract, although in rare cases they are known to occur in extragastrointestinal locations, including the larynx, middle ear, and pancreas. Malignancies of the parotid gland are uncommon (approximately 25% of parotid neoplasms), and to the best of our knowledge, a primary carcinoid tumor of the parotid has not been previously described in the literature. Reports of parotid carcinoid tumors during the past 30 years have described the presence of nonparotid primary carcinoid tumors (usually gastrointestinal) that had been diagnosed and treated several years prior to the presentation of the parotid lesion. Under such circumstances, the parotid lesion may be assumed to have been a metastatic rather than a primary carcinoid. This report documents what we believe is the first case of a primary carcinoid tumor of the parotid gland. We detail the clinical, surgical, radiologic, immunologic, and histochemical findings associated with its diagnosis, and we describe our management of this case. Although a primary carcinoid in this location is exquisitely rare, knowledge of such lesions is important because their management is substantially different from that of other parotid tumors. In particular, it is important to differentiate them from metastatic tumors from other sites.

Malignant peripheral nerve sheath tumors of the head and neck: Two cases and a review of the literature

Abstract
Malignant peripheral nerve sheath tumors are uncommon lesions that occasionally affect the head and neck. We describe 2 new cases of head and neck pathology. One tumor involved the parotid gland and resulted in erosion of the temporal bone, and the other affected the lower lip. A rapid diagnosis has significant implications for management because of the tumor's potential for aggressive behavior and its high rate of recurrence. To the best of our knowledge, lip involvement is rare and temporal bone involvement has not been previously described.
