Abstract

Prostate cancer metastatic to the parotid gland is exceedingly rare, as only 10 cases have been previously reported in the literature. Symptoms may mimic a parotid infection or suggest a primary parotid tumor. We report a new case of carcinoma of the prostate metastatic to the parotid. The tumor was painful and had invaded the mandible. Fine-needle aspiration of the mass and immunohistochemical staining for prostate-specific antigen confirmed the diagnosis. The patient died 1 month later of an unrelated cause.

Sclerosing mucoepidermoid carcinoma of the parotid gland: Case report

October 31, 2009     Shai Y. Shinhar, MD, MSc
article

Abstract

Mucoepidermoid carcinoma is the most common malignant salivary gland neoplasm. Its sclerosing morphologic variant, however, is an extremely rare entity. Only 7 cases have been reported in the literature, and only 2 of those reports have discussed this unusual malignancy in detail. This report describes a case involving a 57-year-old woman with an intermediate-grade sclerosing mucoepidermoid carcinoma of the parotid gland. She underwent superficial parotidectomy and radiation therapy with excellent results. Diagnosis and options for treatment are discussed, as well as a review of the literature, which demonstrates that this is an extremely rare malignancy with no strict protocol for treatment.

Atypical lipomatous tumor/well-differentiated liposarcoma of the parotid gland: Case report and literature review

article

Abstract

Although liposarcoma is the second most common soft-tissue sarcoma in adults, it is exceedingly rare in the head and neck. According to our MEDLINE search, only 11 cases of liposarcoma of the parotid gland have been reported since 1968. We report a new case of primary atypical lipomatous tumor/well-differentiated liposarcoma of the parotid gland in a 77-year-old man. Because only a very limited number of case reports and small series have been published on liposarcoma in the head and neck, we also provide a review of the literature on this uncommon disease entity.

Intraparotid facial nerve schwannoma: Clinician beware

article

Abstract

Intraparotid facial nerve schwannomas are rare neoplasms that are challenging to diagnose and manage. Many patients present with a painless, palpable facial mass. The presence of facial paralysis is variable. Imaging studies and fine-needle aspiration cytology are not always helpful in preoperative diagnosis. With early diagnosis of facial nerve schwannoma, management of the patient can be planned and, ultimately, facial nerve function optimized. By reviewing the literature and 2 cases from a series of patients seen in our practice, we provide insight into the current diagnosis and treatment of a rare pathology.

Distal parotid duct pseudocyst as a result of blunt facial trauma

article

Abstract

The sequelae of sharp trauma to the parotid duct, such as sialocele and salivary fistula, are well known. In contrast, complications of blunt trauma to the parotid duct are not as common. A search of the English-language literature revealed 2 cases of parotid pseudocysts caused by blunt trauma. Although no well-known management protocol exists for complications of blunt trauma to the parotid duct, the treatment modalities for sharp trauma complications potentially could be applied. We describe a case of a blunt-trauma-induced distal parotid duct pseudocyst that remained refractory to conservative management, including repeated aspiration and cannulation of the duct. After characterizing and localizing the pseudocyst with sialography and cross-sectional imaging, we performed a surgical repair. This repair involved marsupialization of the parotid duct to the level of the pseudocyst. The edges of the opening of the proximal duct and the pseudocyst were sutured to the oral mucosa, and a small intraoral drain was left in the pseudocyst to prevent collapse and abscess formation. The drain was removed after 5 days, and the patient experienced no further problems during 14 months of follow-up.

Epidermoid carcinoma involving the parotid gland and orbital region: Case report of a rare entity

article

Abstract

Epidermoid carcinoma (also known as squamous cell carcinoma) of the parotid gland is more prevalent among the elderly, as are other head and neck tumors. In most cases it is observed either as a nodal metastasis of a primary tumor that drains into the parotid area or as a direct extension of a tumor that has originated in the upper dermis. Primary epidermoid carcinomas arising directly from the parotid gland are extremely rare. Similarly, secondary invasion of the orbital region by a neighboring tumor is more common than primary epidermoid carcinoma of the orbit, which is also rare. In this article, we discuss the diagnosis and treatment of a rare case of epidermoid carcinoma simultaneously invading the parotid gland and the orbit.

Multiple pilomatrixomas: Case report and literature review

March 31, 2008     Shashidhar Sadda Reddy, MD, MPH, Swarupa A. Gadre, MD, Patrick Adegboyega, MD, and Arun K. Gadre, MD
article

Abstract

Pilomatrixoma is a rare, benign, circumscribed, calcifying epithelial neoplasm that is derived from hair matrix cells. Multiple pilomatrixomas are uncommon. We describe a case of multiple pilomatrixomas in a 23-year-old black woman who presented with lesions on her face and back. Based on the results of the clinical examination, she was provisionally diagnosed with either calcified sebaceous cysts or calcified lymph nodes. She underwent surgical excision of the masses. On histopathology, the lesions were identified as pilomatrixomas. We attribute our original failure to diagnose this condition to our lack of familiarity with it. We discuss the presentation, differential diagnosis, and other characteristics of pilomatrixomas.

Bilateral multinodular oncocytomas of the parotid arising in a background of bilateral oncocytic nodular hyperplasia

Abstract

Oncocytic tumors of the major salivary glands are rare, accounting for less than 1% of all salivary gland tumors. When they do occur, these neoplasms typically present as solitary nodules that affect only one major salivary gland, usually the parotid. Multiple bilateral multinodular tumors are rare. We report the case of a 53-year-old woman with a case of synchronous multiple bilateral multinodular oncocytomas that arose in a background of bilateral oncocytic nodular hyperplasia in the parotid glands. The patient underwent superficial parotid resections, and at the 4-year follow-up, she exhibited no evidence of recurrence.

Squamous cell carcinoma of the accessory parotid gland

September 30, 2007     Ryan F. Osborne, MD, FACS
article

An 85-year-old man presented with a persistent right accessory parotid gland carcinoma after surgical resection and radiotherapy (figure 1). The patient had been initially diagnosed by fine-needle aspiration as having a moderately to well-differentiated keratinizing squamous cell carcinoma of the right accessory parotid gland.
