AIM: To create a predictive score for the discrimination between benign and malignant parotid tumors using elastographic parameters and to compare its sensitivity and specificity with standard ultrasound. METHODS: A total of 124 patients with parotid gland lesions for whom surgery was planned were examined using conventional ultrasound, Doppler examination, and shear wave elastography. Results of the examinations were compared with those ones of histology. RESULTS: There were 96 benign and 28 malignant lesions in our cohort...

Eating disorders are a potentially life-threatening group of mental disorders, which affect a patient's relationship with food and their body. This manifests itself through chaotic and disordered eating habits. One such eating disorder is bulimia nervosa, which has a lifetime prevalence of 1%. While there is consensus that bulimic behaviour directly causes dental erosion due to vomiting and acidic food choices, there is less clear evidence for a direct link between bulimia nervosa and dental caries, although there does still appear to be an association...

Approximately 1%-10% of patients with HIV infection have been reported to have salivary gland enlargement. Parotid swelling in patients with HIV is often associated with salivary gland disease, including benign lymphoepithelial cysts (BLECs). The presence of BLEC can serve as an indicator of HIV infection, and the diagnosis of HIV-associated BLEC is usually based on clinical course, HIV confirmatory blood testing, such as western blot or viral detection, and imaging studies, but not on biopsies or immunostaining...

Heerfordt-Waldenström syndrome is a rare subacute variant of sarcoidosis, characterized by enlargement of the parotid or salivary glands, facial nerve paralysis and anterior uveitis. Granulomas with a peripheral lymphocyte deficit are found in the anatomic pathology of affected organs. It is normally self-limiting, with cure achieved between 12 and 36 months, but some prolonged cases have been reported. Diagnosis of the syndrome is clinical, and treatment depends on the degree of systemic impairment. Oral corticosteroids represent the first line treatment option...

A 90-year-old woman underwent laparoscopic exploratory laparotomy for evaluation of suspected mesenteric ischemia. She was promptly extubated postoperatively and transferred to the intensive care unit, where on the first postoperative day she developed hypoxemia necessitating initiation of noninvasive ventilation (NIV) with bilevel positive airway pressure (BiPAP). After 8 hours of BiPAP, she was noted to have swelling, erythema and tenderness in the right preauricular area. Ultrasound evaluation demonstrated an enlarged right parotid gland...

A 76-year-old man was incidentally found on a CT scan to have lymphadenopathy and bilateral kidney enlargement suggestive of infiltrative renal disease. He was largely asymptomatic but had bilateral salivary and lacrimal gland enlargement. A grossly elevated serum IgG (>70 g/L) with concomitant suppression of other immunoglobulins, a small IgG restriction, and a parotid biopsy revealing lymphoplasmacytic infiltrate with slight kappa light chain excess all suggested a lymphoproliferative disorder (LPD)...

The more common causes of parotid enlargement in children are infections and inflammatory conditions. Primary neoplasms of the parotid glands are rare in pediatric age group; however, secondary malignancies have been reported in survivors of childhood leukemia. The parotid glands have been the sites of relapses in acute lymphoblastic leukemia (ALL) and acute myeloid leukemia. However, bilateral parotid involvement as an initial presentation of ALL is rarely reported. We present a case of an 8-year-old boy who presented with bilateral parotid enlargement as an initial manifestation of ALL...

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...

Orbital involvement in systemic sarcoidosis is a rare condition. We report a case of orbital sarcoidosis with bilaterally huge lacrimal gland involvement as the initial manifestation of systemic sarcoidosis. A 20-year-old woman admitted the ophthalmology department with progressive bilateral upper eyelid swelling for 6 months. The only pathologic finding was the presence of bilateral, symmetrical, solid, lobular masses at the lateral upper eyelids at the location of lacrimal glands. On systemic examination, bilateral parotid and submandibular glands appeared swollen...

REVIEW
A Agaimy, H Iro, J Zenk
Salivary gland tumors and tumor-like lesions in the pediatric population are uncommon. They comprise a heterogeneous group of infectious/inflammatory and neoplastic conditions. Pediatric salivary neoplasms include benign tumors of mesenchymal or epithelial origin as well as malignancies of epithelial (carcinomas), mesenchymal (sarcoma) or hematolymphoid (lymphoma) derivation. Infectious/inflammatory conditions and hematolymphoid malignancies may represent either genuine parenchymal pathology or conditions involving intraglandular lymph nodes of the parotid glands (intraglandular lymphadenopathy and intraglandular nodal lymphomas)...

The technique of jaw tracking can be used in volumetric modulated arc therapy (VMAT) and intensity modulated radiation therapy (IMRT). In this technique, jaw tracks apertures of the multi leaf collimator (MLC) during irradiation. It is reported that dose variation is occurred by the changing accuracy of MLC position in VMAT and IMRT. Though jaw moves dynamically in the irradiation by using this technique, the influence of the jaw position accuracy on dose variation is not examined. The purpose of this study is to verify the influence of jaw position accuracy on dose variation in VMAT using jaw tracking...

BACKGROUND: Salivary gland secretory carcinoma is usually a low-grade neoplasm. However, high-grade transformation can occur and has important implications for clinical outcome. METHODS: A patient presented with an enlarging buccal mass. Magnetic resonance imaging (MRI) showed a tumor with a biphasic appearance along the right parotid duct. Local excision and histopathologic examination confirmed the diagnosis of secretory carcinoma with high-grade transformation...

Kimura disease (KD) is a rare chronic inflammatory disorder of unknown etiology representing as solitary or multiple subcutaneous nodules predominantly in the head and neck region. Common sites of involvement are preauricular region, forehead and scalp. The soft tissue localization is often associated with regional lymphadenopathy and enlargement of the major salivary gland. The authors report a patient with KD involving the right parotid and left temporal region managed successfully at our center using a combination of debulking superficial parotidectomy and medicinal therapy...

Ultrasound of the salivary glands is a specific examination for detecting pathology of salivary glands in the diagnosis of Sjögren's syndrome. It is easy to learn, rapidly performed, non-invasive and inexpensive. Other imaging techniques, such as sialography and scintigraphy, are currently only rarely performed. For the examination, linear ultrasound probes with frequencies between 7 and 12 MHz are recommended. Such probes are already widely available to the rheumatologist performing musculoskeletal ultrasound...

We report a rare case of arteriovenous malformation(AVM)of the parotid gland associated with Cowden disease successfully treated with preoperative embolization followed by surgical removal. A 39-year-old man with a history of Cowden disease presented with a pulsating and growing mass on his left lower jaw. Contrast-enhanced computed tomography(CT)and angiography revealed a high-flow AVM in the deep lobe of the left parotid gland. After intravascular embolization of the feeding arteries, surgery was performed using the NIM-response<sup>®</sup>3...

PURPOSE: To determine whether magnetic resonance (MR) tractography of facial nerve (VIIn) is useful to detect perineural invasion in case of parotid cancers. MATERIALS AND METHODS: Thirty patients, aged 18 or over, were enrolled in this prospective study between December 2013 and March 2016 (IRB 5891), with a diagnosis of parotid tumors (15 malignant, 15 benign). They have undergone preoperative MR scans (3.0-T) before surgical management. The parameters of the diffusion-weighted (DW) sequence were b-value of 1000s/mm(2); 32 directions; voxel size: 2mm isotropic; scan time: 9' The post-processing generates whole-neck constrained spherical deconvolution (CSD)-based tractography data and super-resolution track-weighted imaging (TWI) technique...

The intimate anatomical relationship of the facial nerve to the parotid parenchyma has a significant influence on the presenting signs and symptoms, diagnosis and treatment of parotid neoplasms. However, to our knowledge, hyperactivity of this nerve, presenting as facial spasm, has never been described as the presenting sign or symptom of a parotid malignancy. We report a case of carcinoma arising in a recurrent pleomorphic adenoma of the left parotid gland (i.e., carcinoma ex pleomorphic adenoma) that presented with hemifacial spasms...
