Auriculotemporal Nerve

Plexiform neurofibromas are benign tumors that tend to occur in patients suffering from neurofibromatosis type 1 (NF-1). This report addresses a rare case where the tumor affected the parotid gland, deriving almost exclusively from the peripheral portion of the facial nerve. A 6-year-old male was referred to us complaining about a gradually enlarging swelling over the right parotid area. Imaging localized the lesion to the superficial lobe of the parotid gland, suggesting a neurofibroma. Cosmetic disfigurement and a functional deficit led us to perform complete surgical resection. Meticulous surgical dissection as well as auriculotemporal nerve origin made complete extirpation possible with almost zero morbidity and ensured alleviation of both aesthetic impairment and pain. This is the first case of an intraparotid PN in a pediatric NF-1 patient, which originated from branches of the auriculotemporal nerve and particularly from fibers of the autonomic nervous system. Radical surgical excision was decided according to established decision-making algorithms.

The aim of this paper was to present the ultrasound (US) and computed tomography (CT) appearance of a patient with salivary duct carcinoma of the parotid gland. US showed a voluminous mass of the parotid gland, with multiple calcifications. Furthermore, it revealed regional multiple lymph nodes with malignant characters. Sonoelastography of the lesion and lymph nodes detected increased rigidity. Contrast enhanced CT scan of the neck completed the data description regarding the mass expansion and invasion of surrounding tissues. US and CT imaging features played a key role in establishing the malignant character of the mass and lymph nodes.

Objective: This study investigated the effectivity of Magnetic Resonance Imaging (MRI) findings and Apparent Diffusion Coefficient (ADC) value in evaluating parotid gland tumors (PGTs), and aimed to reduce the biopsy procedure before surgery. Methods: This retrospective study included 54 PGTs of 42 patients’ (24 female, 18 male, mean age; 51.4±15.9). All of the patients had an MRI, and histopathologic diagnosis. The signal intensity [T1 and T2 Weighted (W), T1W after intravenous contrast agent injection] and mean ADC values of the PGTs were measured. Also contrast enhancement pattern (homogenous, heterogeneous, peripheral or none), margin features (well or ill-defined), sizes, location (superficial lobe/deeplobe/both), perineural spread, presence of lymphadenopathy, and extension to adjacent structures were noted. Results: The distribution of PGTs was; 21 pleomorphic adenomas, 18 Warthin tumors, 2 lymph nodes, 2 mucoepidermoid carcinomas, 5 adenoid cystic carcinoma, 1 basal cell carcinoma,2 metastases and 2 lymphomas; (13 malignant and 41 benign lesions). Morphologic parameters; ill-defined margin, perineural spread, lymphadenopathy, and extension to adjacent structures were found to be significantly associated with malign lesions (p<0.01). There was a significant difference between ADC values of malignant and benign PGTs (p<0.05). Also ADC values and T2 signal intensity was significantly lower in Warthin tumors rather than pleomorphic adenomas (p<0.05). Conclusions: Mean ADC values when considered with morphological features may be accessible methods to distinguish benign and malignant PGTs, also ADC values and T2 signal intensity may be useful for differentiating pleomorphic adenomas from Warthin tumors, thereby reducing the number of biopsies and thus complications.

Superficial Lobe

The parotid gland consists of two lobes: superficial and deep with regard to its relation with the facial nerve. It is wrapped around the mandibular ramus and secretes saliva through the parotid (Stensen's) duct. It is a paired organ, weighing 15-30g each. Its superficial lobe overlies the lateral surface of the masseter muscle and is bounded superiorly by the zygomatic arch, while its deep lobe is located in the pre-styloid compartment of the parapharyngeal space between the mastoid process posteriorly, ramus of mandible anteriorly, and external auditory meatus superiorly. Medially, the gland reaches to the styloid process. Inferiorly, the parotid tail extends down to the anteromedial margin of sternocleido-mastoid muscle. Several structures run through the parotid gland, namely, terminal segment of external carotid artery, retro-mandibular vein, parotid lymph nodes, and facial nerve, which soon gives two divisions (temporo-facial and cervico-facial) that give off five branches inside the gland radiating forwards. This chapter explores the surgical anatomy of the parotid gland.

Lipomas are rarely found in the parotid gland region. Because of their rarity at this site, they are not often considered in the differential diagnosis of parotid tumors. The parotid lipoma is a slowly growing, asymptomatic, freely movable, soft mass. Preoperative diagnosis is generally difficult. We present a case of a slowly enlarging mass of the parotid region in a 44-year-old man that proved to be a lipomatous tumor of the parotid gland. We also review 42 other cases from the literature. Our patient's huge tumor was located in the superficial lobe of the gland, and a parotidectomy with preservation of the facial nerve was performed. There was no complication or recurrence of the tumor after a follow-up of 1 year.

Histopathologic Features

Non-neoplastic cysts of the salivary glands are uncommon and represent 2-5% of all salivary gland lesions. They are mainly mucoceles or salivary duct cysts. Unlike a mucocele, which is surrounded by granulation tissue, the salivary duct cyst is lined by epithelium. Salivary duct cysts are more common in the oral minor salivary glands and rarely occur in the major salivary glands, show a marked predilection for the superficial lobe of the parotid, and represent 10% of all salivary gland cysts. Neoplastic differentiation of the lining of the salivary duct cyst has been reported. We report a case of a salivary duct cyst of the left parotid gland, with a review of radiographic and histopathologic features.

Pleomorphic adenomas are benign salivary gland tumours, which predominantly affect the superficial lobe of the parotid gland. The “pleomorphic” nature of the tumour can be explained on the basis of its epithelial and connective tissue origin. The tumour has a female predilection between 30-50 years of age. Slowly progressing asymptomatic swelling is the usual presentation of the tumour. Surgical excision of the tumour mass forms the mainstay of treatment, with utmost care taken to preserve the facial nerve. This case report aims to throw light on an interesting case of pleomorphic adenoma of the parotid gland in a 10 years old female patient. The patient presented with a slowly progressing asymptomatic swelling on the right side of the face, which was diagnosed to be pleomorphic adenoma of right parotid gland. The aim of the study is to discuss how to proceed regarding the further management.
