Adamantinoma-like Ewing sarcoma (AES) is a rare variant of Ewing sarcoma family of tumors (EFTs), primarily affecting bone and soft tissue. AES has mixed features of Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) and adamantinoma with a complex immunoprofile and EWSR1 gene rearrangements. Herein, we report a 72-year-old male who presented with left parotid mass, right neck mass and thyroid nodules. Fine needle aspiration of the left parotid mass displayed nests of monotonous epithelioid cells with basaloid features in a background of small round blue cells and lymphocytes...

The ectopic accessory parotid system (EAPS) connotes an extra parotid tissue with its ductal outlet that is morphologically distinct from the main parotid gland and its drainage system. Clinically presenting as a saliva-draining cheek fistula near the oral commissure, this rare congenital anomaly is almost always associated with ipsilateral preauricular appendages and occasional mandibular hypoplasia, and is considered a variant of the oculo-auriculo-vertebral spectrum. This report discusses the embryology, clinical details, and management aspects in a new patient, highlighting the role of magnetic resonance imaging in, for the first time, tracking the ectopic salivary system, and establishing its independent existence...

This editorial explores the controversies concerning the surgical management of the deep portion of the parotid gland. Specifically, when should the parotid deep lobe be removed if there is metastatic cancer to a superficial parotid node or when a primary aggressive cancer is found in the superficial lobe? The background, indications, rationale, and results of removing the deep lobe nodes are reviewed. Removal of the deep lobe is done to optimize the oncologic outcome for the patient. Deep lobe parotidectomy plays an important role in the treatment of many parotid gland malignancies...

Sialolithiasis is the formation of calculi or sialoliths in the salivary gland. It is the most common benign condition of the salivary gland. Sialolithiasis can occur in all salivary glands. The submandibular gland is most commonly affected followed by the parotid gland. Calculi commonly measure less than 10 mm. Calculi of more than 15 mm are termed giant salivary gland calculi and are infrequently reported in the literature. Here, we report a case of unusually large submandibular gland calculus of 5 cm in greatest dimension which caused erosion of the oral cavity...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report provides new insights into feline laryngeal diseases which could result in laryngeal metastasis with slight mucosal irregularity alone and without obvious radiographic abnormalities...

Salivary gland neoplasms are a relatively uncommon disease, with nearly one case per 100.000 adults estimated per year and an overall incidence of 1% of all neoplasms. The benign neoplasms are majority and the prognosis depends on the histologic type, grade, localization, soft tissue infiltration, regional and distant metastasis. The main treatment is surgery with caution to facial nerve in the major salivary glands, followed by radiotherapy and chemotherapy in selected cases. The objective of this review is to provide the lector an historic approach about salivary gland diseases treatment, with special attention to the parotid neoplasms and its peculiarities associated to those who studied these glands in their history course...

Mammary analogue secretory carcinoma (MASC) is a rare salivary gland malignancy that exhibits resemblance with secretory carcinoma of the breast (SC) due to the presence of ETV6-NTRK3 gene fusion, formerly classified as acinic cell carcinoma. It is a slowly growing painless tumor that exhibits wide range of clinical behavior. This tumor typically affects middle aged people. Less than 100 such cases have been reported in the literature so far with only 8 case reports of patients less than 19 years of age. Very little is known about the clinical management of such cases...

PURPOSE: To evaluate whether diffusion tensor imaging (DTI) can be used to differentiate malignant parotid gland tumors from the benign ones. MATERIALS AND METHODS: The study population comprised 59 parotid gland tumors (24 Warthin's tumors, 19 pleomorphic adenomas, seven other benign tumors, and nine malignant tumors). Single-shot echo-planar DTI was performed with motion-probing gradients along 30 noncollinear directions (b=1000s/mm(2)) at 3.0T. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values for benign and malignant tumors were compared using the Mann-Whitney U test...

REVIEW
Jacob G Yetzer
Imaging studies are essential components of tumor diagnosis, staging, assessing tumor response to neoadjuvant and adjuvant therapies, and postoperative surveillance on completion of definitive treatment. Treatment of early stage clinically node negative oral cavity squamous cell carcinoma is controversial. Approximately 3% of all head and neck tumors arise within the parotid gland and most often within the superficial lobe, lateral to the facial nerve; about 80% are benign and most are pleomorphic adenoma. In patients with dry eyes failing multiple other treatment modalities and facing ongoing pain and loss of vision, microvascular transplant of the submandibular gland is a viable option...

OBJECTIVES: The cervical approach to parapharyngeal space tumors is blind in cases involving an approach to the vicinity of the skull base from below. We therefore devised a procedure to improve the safety of surgery in the vicinity of the skull base. METHODS: With this surgical technique, the temporal branch from the main trunk is first identified, as in the case of parotid gland tumor surgery. We then approach the skull base by entering the posterior aspect of the parotid gland tissue from above the temporal branch and anterior auricular space, allowing clear visual confirmation of the upper part of the tumor...

Warthin tumor is the second most common salivary gland neoplasm. It occurs more commonly in males than in females. Malignant transformation in Warthin tumor is a rare but well-recognized phenomenon; however, the development or presentation of lymphoma in a Warthin tumor is rare. An 80-year-old man presented with painless mass of the right parotid gland of 2 years duration with recent ulceration of the overlying skin and right cervical lymphadenopathy underwent a surgical resection of parotid mass and biopsy of the periglandular lymph nodes...

Renal cell carcinoma is an unpredictable malignancy. Sometimes, metastases are the disease debut. On the other hand, metastases could present years after treatment of the primary tumor. Four clinical cases of atypical metastases in the head and neck location are presented: parotid gland, mandibular bone, attached molar gingiva and masticator space. Physiopathology, clinics, histology and management of metastatic renal cell carcinoma at those anatomical regions are reviewed.

Daan Nevens, Sandra Nuyts
OBJECTIVE: The purpose of this study is to see whether sparing the superficial contralateral parotid lobe can help limiting xerostomia following radiotherapy for head and neck cancer. METHODS: Eighty-eight patients that were included in 2 prospective randomized studies, were analysed in the current study. Using the dosimetry of both the parotid glands, we divided our patients in 4 groups. Group 1 includes patients where we were able to reduce the radiation dose below the threshold in order to spare both the ipsilateral and contralateral parotid glands, group 2 consist of patients where only the contralateral parotid gland could be spared...
