Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve. The first patient, a 48-year-old woman, presented with what appeared to be a parotid tumor at the stylomastoid foramen; she underwent a parotidectomy, transmastoid facial nerve decompression, and a shave biopsy of the tumor...

INTRODUCTION: Sialendoscopy has changed the management of obstructive sialadenitis. Nowadays, minimally invasive techniques evolve to preserve salivary gland function. Intraductal lithotripsy allows stones fragmentation and retrieval without opening the salivary duct. We report our experience with the StoneBreaker (SB), a new lithotripter with improvement using a sterile bag that permits reuse of the SB without passing to sterilization. TECHNICAL NOTE: The non-sterilized SB was used into a sterile camera sleeve in 5 patients, 3 submandibular lithiases and 2 parotid lithiases...

INTRODUCTION: Minimally invasive techniques (MIT), including sialendoscopy, extracorporeal lithotripsy and intraoral approach, have to be preferred in parotid stones removal. In case of MIT failure, a combined intra- and extra-oral approach can be achieved. The aim of our study was to evaluate the efficacy and the complications of these combined approaches. MATERIALS AND METHODS: A retrospective study has been conducted on patients treated between 2006 and 2015...

OBJECTIVE: To investigate the clinical significance of cell blocks obtained by ultrasound-guided fine needle aspiration in diagnosing parotid gland masses. METHODS: Cell blocks were made in 285 parotid gland masses by ultrasound-guided fine needle aspiration. Diagnosis was conducted using the cell blocks. Non-tumor masses were subjected to conservative treatment, and cysts and tumors were treated with surgery. The cell block sections from masses with the diagnosis of adenoid cystic carcinoma (ACC) and pleomorphic adenoma (PA) were applied to the detection of immunocytochemical staining for the stem cell factor receptor CD117...

Melanotic neuroectodermal tumor of infancy is a rare congenital pigmented neoplasm of neural crest origin, locally aggressive, growing rapidly and developing during the 1st year of life. It most commonly arises from the maxilla, cranial vault, and mandible. Occasionally, it exhibits malignant behavior with local lymph nodes involvement. Cases misdiagnosed and left untreated for a long time can present challenges due to the tumor mass and infiltration. In these cases, adjuvant chemotherapy can be extremely helpful before radical excision...

Chronic obstructive parotitis (COP) is a common disease of the parotid gland. A total of 104 patients with COP were identified and randomized into a treatment group (52 cases) and a control group (52 cases). All patients underwent sialography and salivary gland scintigraphy (SGS) examinations before surgery. The patients in the treatment group received chymotrypsin combined with gentamicin via interventional sialendoscopy to irrigate the duct, and the control group received gentamicin alone. All patients were asked to record their pain on a visual analogue scale (VAS) before treatment and at 1 week, 2 weeks, 1 month, 3 months, and 6 months after surgery...

Neoplasms located in the parotid region, temporal bone, infratemporal fossa, and lateral skull base represent a challenge due to their difficult anatomic location and surrounding neurovascular structures. A variety of surgical approaches are appropriate to access this area, although several of them can place the auricular blood supply in danger. If the auricular blood supply is compromised, ischemia and, eventually, avascular necrosis of the auricle can occur. Auricular necrosis often can cause patients a delay in adjuvant radiation therapy and result in the need for additional reconstructive procedures...

Mucosa-associated lymphoid tissue (MALT) lymphoma of the liver is a very rare condition and thus the diagnosis may be challenging. The clinical presentation is usually variable, ranging from minimal clinical symptoms to severe end stage liver disease. In this paper, we describe the clinicopathologic findings in two cases of primary hepatic MALT lymphoma. One case is an 80-year-old female with no underlying chronic liver disease and the second case is a 30-year-old female with autoimmune hepatitis complicated by MALT lymphoma...

RATIONALE: Lymphoepithelial carcinoma (LEC) is a rare malignancy with the histopathological feature of undifferentiated carcinoma and an intermixed reactive lymphoplasmacytic infiltration. Although clinically significant because of its malignant nature, it is difficult to make a differential diagnosis by preoperative imaging. Here, we report 3 cases of primary LEC arising in the major salivary glands, which showed unusual imaging features unlike other malignant tumors. PATIENT CONCERNS: Our first case is a 44-year-old man with LEC in the right parotid gland, the second case is a 71-year-old woman with LEC in the right submandibular gland, and the third case is a 35-year-old woman with LEC in the right parotid gland...

A49 -year-old woman presented with a 3.5 cm mass in her right breast. Mammography revealed a lobular mass with poorly defined margins and no microcalcification. Ultrasonography showed a hypoechoic mass with an irregular margin. The tumor was diagnosed as breast carcinoma using a core needle biopsy. The patient underwent a modified radical mastectomy with sentinel lymph node biopsy, and received adjuvant chemotherapy. The tumor consisted of 2 types of carcinoma. The center of the tumor was solid-tubular carcinoma, and the periphery was acinic cell carcinoma(ACC)...

Myoepithelial cells (MECs) exist on the basal surface of acini in major exocrine glands, include myofilaments and various constructive proteins, and share characteristics with smooth muscle and epithelial cells. MECs project several ramified processes to invest acini, and possibly contract to compress acini to support the secretion by the glandular cells. However, the functional roles of MECs in salivary secretion are still unclear. We investigated morphological changes in immunostained MECs using the anti-α-smooth muscle actin (αSMA) antibody in operated or non-operated contralateral (NC) submandibular glands after partial or total resection...

OBJECTIVE: Marginal mandibular nerve paralysis is the most frequent complication of benign parotid tumor surgery and results in cosmetic deformity. The purpose of this study was to develop a new electroneurography method for marginal mandibular nerve paralysis using electroneurography (ENoG) and judge its usefulness for clinical practice. METHODS: Twenty-seven patients who underwent surgery for benign parotid tumor were enrolled. We proposed and use the mandibular angle method, in which the recording electrode was placed on the skin above the depressor anguli oris muscle while the reference electrode was placed on the skin of the parietal region, and percutaneous electrical stimulation was applied to enclose the mandibular angle that could measure the function of the marginal mandibular nerve solely...

First bite syndrome is a potential complication of surgery involving the infratemporal fossa, deep lobe of the parotid gland and parapharyngeal space. It is described as an acute and intense pain in the parotid region caused with the first bite of each meal. It is related to damage to sympathetic innervation of the parotid gland. Parasympathetic hyperactivation is believed to stimulate an exaggerated myoepithelial cell contraction causing pain. Usual analgesic treatments have poor results. Botulinum toxin type A causes parasympathetic nerve paralysis of the parotid gland and this fact would minimize salivation and decrease first bite syndrome...
