Synchronous bilateral mucoepidermoid carcinoma of the parotid gland

It is rare for a parotid gland tumour to arise bilaterally, the most common example being Warthin’s tumour. Furthermore, it is rare for a parotid gland cancer to occur bilaterally. Here, we describe a case of synchronous bilateral mucoepidermoid carcinoma arising in the parotid gland. A case of bilateral facial nerve dysfunction is presented in which aggressive surgery failed to save the life of a 48-year-old man. This is the first such case reported in the available English literature.

Facial nerve paralysis associated with a parotid gland tumour classically denotes malignancy. Only a few case reports have indicated benign parotid tumours as a cause of facial nerve palsy. We present a new case of facial nerve paralysis secondary to Warthin’s tumour of the parotid gland. It is important for clinicians to be aware that, on rare occasions, facial nerve dysfunction may result from benign parotid disease.

Pleomorphic Adenomas

AbstractAn oncocytic mucoepidermoid carcinoma and an oncocytic pleomorphic adenoma occurred in a 47-year-old male and a 75-year-old female, respectively. Both presented as asymptomatic parotid gland masses without evidence of facial nerve paralysis and were treated by superficial parotidectomy. There has been no evidence of recurrence or metastasis. Oncocytic change is rare in major salivary gland mucoepidermoid carcinoma with only two previously reported cases. Marked oncocytic transformation of pleomorphic adenomas can cause their confusion with oncocytomas. Recognition of oncocytic differentiation in various salivary gland tumours is important to avoid misclassification of these lesions.

Accessory Parotid Gland

Purpose: The head and neck surgeon’s fascination with parotid surgery arises from the gland’s spectrum of histopathological presentations, as well as the diversity of its morphological features. A mass arising in the mid-cheek region may often be overlooked as a rare accessory lobe parotid neoplasm. This report serves to revisit the topic of accessory parotid gland neoplasms to emphasize proper management, particularly the surgical aspects, so that consequences of salivary fistula, facial nerve paralysis, and recurrence are avoided. Case report: We report a case of mucoepidermoid carcinoma which was assessed pre-operatively as arising from the accessory parotid gland of a 11-year-old female. She had complained of a painless and round mass of the left cheek for a duration of 12 months. Sialography, ultrasonography, CT scan and MRI were performed preoperatively. Sialography revealed a small duct separating from the Stensen’s duct. CT and MRI showed that the tumor with smooth outline was lying on the masseter muscle and detached from the main parotid gland. The preoperative diagnosis was an accessory parotid gland tumor. The tumor was removed without facial nerve injury via standard parotidectomy incision. The tumor was composed of mucous, intermediate and epidermoid cells. The pathological diagnosis was low-grade mucoepidermoid carcinoma. Conclusions: Accessory parotid gland neoplasms are rare and may present as innocuous extraparotid mid-cheek masses. A high index of suspicion, prudent diagnostic skills (including fine-needle aspiration [FNA] biopsy followed by computed tomography [CT] imaging), and scrupulous surgical approach (extended parotidectomy-style incision and limited peripheral nerve dissection when possible) are the keys to successful management of these lesions.
