“…Accessory parotid gland tumor is often noticed as a painless and firm mass in the mid-portion of the cheek. The most common tumor arising in the accessory parotid gland is benign pleomorphic adenoma, followed by mucoepidermoid carcinoma (6,7,13,14,15). These previous data are quite different from the frequency of mucoepidermoid carcinoma in the main parotid glands.…”

“…There have been rare reports of mucoepidermoid carcinoma arising in the accessory parotid tissues in children as far as we have reviewed (22). The ages at diagnosis in the previous 23 were over 20 years (6,7,13,14,15). The sex difference was described in seven cases; five males and two females and the remaining 16 cases unknown.…”

“…For preoperative diagnosis, several examinations such as ultrasonography, CT, MRI and sialography were performed in our case and they were useful for a diagnosis by detecting the size, shape and location of the tumor. As the surgical approach to the accessory parotid tumor, usual parotidectomy incision is preferable for preventing injury to the facial nerve and Stensen's duct, in contrast to a direct cheek incision (6,7,13,14,15). The zygomatic and buccal branches of N. VII can be identified by using nerve stimulator and/or microscope without dissection of the facial nerve in the main parotid gland.…”

“…The incidence of this tumor arising in the auxiliary parotid gland ranges from 1 to 7.7 % of all parotid gland tumors (13,14). In previous literature, the frequency of malignant tumors is relatively high as compared with that of main parotid tumors and the reported cases were adults (6,7,13,14,15). In this report, we present a case of a 11-year-old female with mucoepidermoid carcinoma arising in the 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.

“…This may indicate that the original lesions were in fact retention cysts, in which part of the ductal epithelium of the cyst wall changed to a MEC. 13 In this present case, given that the FNA pathological report described rare presence of epithelial cells and no solid component, and the clinical and radiographic benign appearance of the lesion, we decided to treat it with an excisional biopsy including the excision of the left submandibular salivary gland. The literature supports complete excision to confirm diagnosis and decrease morbidity and mortality 2,14,15 and reports that radical surgery is contraindicated in small, localized with low-to intermediate-grade.…”

Mucoepidermoid carcinoma mimicking a mucocele (ranula) in the floor of the mouth

Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy. The submandibular gland is rarely involved, about less than 10% of all other major salivary glands. We report a case of a 49-year-old female who presented with a mass on the left side of the floor of the mouth. She was complaining of neck pain for the last 2-3 days and had noticed the mass growing in size and becoming tender to palpation. There was no exacerbation of pain during eating, drinking, or opening of mouth. A multidetector CT scan was made. The radiographic examination revealed a mostly well-defined hypodense area suggestive of mucocele (ranula), which was thought to be corroborated by the clinical findings. The treatment of choice was the complete excision of the mucocele and the left submandibular salivary gland. The histopathological examination surprisingly revealed a low-grade MEC. No further treatment was recommended; however, a follow up was scheduled in 4 months. This atypical location of MEC in the floor of the mouth simulated the clinical and radiographic features of a mucocele. This case highlights the value and importance of using all the available diagnostic tools and modalities for optimal patient management, as the histopathological analysis played an important role to confirm the diagnosis.

Accessory parotid gland tumors are defined as masses within salivary gland tissue located adjacent to Stensen's duct, but separate from the main body of the parotid gland. These tumors usually present as asymptomatic cheek masses. There is a temptation to excise these masses locally; however, the likelihood of injury to branches of the facial nerve is high. The best surgical approach to tumors in the accessory parotid region is via a standard parotid incision and concomitant superficial parotidectomy. Eight patients have been surgically treated with accessory parotid gland masses. Six patients had mixed tumors, one had a low grade mucoepidermoid carcinoma, and one had a localized parotitis. Our approach included a standard parotid incision, raising an anterior flap beyond the mass, and exposing the main trunk of the facial nerve, with careful tracing of all its branches. This approach to accessory parotid gland tumors is superior in that it provides a better margin of resection and minimizes functional and cosmetic deformities. Most importantly, there is less danger of injury to branches of the facial nerve.
