PURPOSE: To study the value of diffusion kurtosis imaging (DKI) in diagnosis of parotid gland disease (PGD) with different pathological patterns and parotid adenolymphoma (PAL). METHODS: Fifty-seven patients with different kinds of PGD were enrolled and underwent DKI and conventional diffusion-weighted imaging (DWI). All patients were categorized into different groups according to their pathological patterns. The result of calculating the value of DKI-derived parameters (Kmean, Krad, Kax, Dmean, Drad, Dax, and FA) and apparent diffusion coefficient (ADC) of DWI were used to study their diagnostic accuracy in PGD with different pathological patterns...

Mammary analog secretory carcinoma is a primary salivary gland neoplasm with histologic, immunophenotypic, and molecular features identical to those of secretory carcinoma of the breast. Similar neoplasms have now been reported to occur in various nonmammary sites including the parotid gland, submandibular gland, sinuses, lip, skin, thyroid gland, and lung. We report, to our knowledge, the first example of a primary vulvar neoplasm with pathologic features identical to secretory carcinoma of the breast and an ETV6-NTRK3 fusion...

Xerostomia induced by radiotherapy is a common toxicity for head and neck carcinoma patients. In this study, the deformable image registration of planning computed tomography (CT) and weekly cone-beam CT (CBCT) was used to override the Hounsfield unit value of CBCT, and the modified CBCT was introduced to estimate the radiation dose delivered during the course of treatment. Herein, the beams from each patient's treatment plan were applied to the modified CBCT to construct the weekly delivered dose. Then, weekly doses were summed together to obtain the accumulated dose...

Tumor-induced osteomalacia is a rare paraneoplastic syndrome, usually caused by small benign mesenchymal tumors. The tumors most arise within the extremities, whereas occurrence within the parotid gland is quite rare. A 54-year-old woman who presented with bone pain and muscle weakness for 2 years was clinically suspected of having tumor-induced osteomalacia. A Ga-DOTANOC PET/CT was performed for localization of the causative tumor. The images demonstrated intense radiotracer accumulation in a soft tissue nodule in deep lobe of the right parotid gland...

Salivary gland tumors account for 3-6% of tumors of the head and neck. About 80% of salivary gland tumors occur in parotid glands. Oxidative stress (OS) is implicated in the origin, development, and whole-body effects of various tumors. There are no data on the occurrence of OS in the parotid gland tumors. The aim of this study was to ascertain if whole-body OS accompanies parotid gland tumors, based first of all on oxidative modifications of blood serum proteins and other markers of OS in the serum of the patients...

NUT carcinoma (NC) represents a rare subset of highly aggressive poorly differentiated carcinomas characterized by rearrangement of the NUT (aka NUTM1, nuclear protein in testis) gene, most commonly fused to BRD4. Originally described as a mediastinal/thymic malignancy, NC has been reported at a variety of anatomic regions including the upper and lower aerodigestive tract. To date, only 7 NC cases of probable salivary gland origin have been reported. We herein describe 3 new cases (all affecting the parotid gland) in 2 women (39- and 55-y old) and 1 man (35-y old)...

Purpose/Aim: To describe a two-phase intensity-modulated radiation therapy (IMRT) treatment planning approach, that is, promising for reduction of oral mucositis risk in locally advanced head-and-neck cancer. Materials and Methods: Ten locally advanced head-and-neck cancer patients who underwent RT were retrospectively collected. Conventional IMRT and volumetric-modulated arc therapy (VMAT) plans were generated for these patients following clinical protocol. Following the first phase of generating conventional IMRT plans, our approach utilized data from Monte Carlo-based kernel superposition dose calculations corresponding to beam apertures (generated from the conventional IMRT plans) and used an exact mathematical programming-based optimization approach applying linear programming (LP) to dose optimization in the second phase...

The aim of this study is to review the imaging appearance of posttreatment salivary gland tumors. The authors discuss the imaging appearance of parotidectomy and reconstructive surgery of parotid defects. Imaging is important to diagnose tumor recurrence and also assess for complications related to surgery, such as a sialocele, fluid collection, hematoma, pseudoaneurysm, and graft stenosis. The article also provides a current-state assessment of the applications of advanced imaging techniques.
