Synchronous unilateral tumors in the parotid glands account for less than 5-10% of all salivary gland neoplasms. Mostly these are cystadenolymphomas, but tumors of different histological types can be found as well. In these cases it is often pleomorphic adenoma in combination with cystadenolymphoma. Read More

Differentiation of benign and malignant parotid uptake on Fluorine 18 Fluro-Deoxy-Glucose Positron Emission Tomography-Computed Tomography (F FDG PET-CT) is of paramount importance due to the poor prognosis of the later but usual quantitative measures such as standardized uptake value (SUV) are not reliable for this purpose. Metabolic heterogeneity, being a characteristic of malignant tumors, would potentially be able to make this distinction. In this study, seventy-one FDG-avid parotid lesions were retrospectively separated histologically into benign and malignant groups. Read More

Background: The Milan System for Reporting Salivary Gland Cytopathology (Milan System) has previously shown its diagnostic utility by categorizing the seven cytology findings in salivary gland lesions. However, there has been lack of study about the risk of high-grade malignancy in the cytology diagnosis based on the Milan System. Thus, we tried to identify the diagnostic ability of the Milan System for high-grade malignancy and to suggest an improved diagnostic approach for preoperative estimation of high-grade malignancy using the Milan System.

Background: Advanced clinical applications, such as dose accumulation and adaptive radiation therapy, require deformable image registration (DIR) algorithms capable of voxel-wise accurate mapping of treatment dose or functional imaging. By utilizing a multistage deformable phantom, the authors investigated scenarios where biomechanical refinement method (BM-DIR) may be better than the pure image intensity based deformable registration (IM-DIR).

Methods: The authors developed a biomechanical-model based DIR refinement method (BM-DIR) to refine the deformable vector field (DVF) from any initial intensity-based DIR (IM-DIR). Read More

Background: Nodular fasciitis (NF) is a clonal, self-limited proliferation that has only rarely been described in the parotid gland. Because of its potential to mimic benign and malignant parotid neoplasms clinically, radiographically, and cytomorphologically, NF is often managed with unnecessary surgery, which is associated with a risk for significant surgical complications.

Introduction: Large anatomical variations can be observed during the treatment course intensity-modulated radiotherapy (IMRT) for head and neck cancer (HNC), leading to potential dose variations. Adaptive radiotherapy (ART) uses one or several replanning sessions to correct these variations and thus optimize the delivered dose distribution to the daily anatomy of the patient. This review, which is focused on ART in the HNC, aims to identify the various strategies of ART and to estimate the dosimetric and clinical benefits of these strategies. Read More

Adamantinoma-like Ewing sarcoma (ALES) is a rare tumor that demonstrates the EWSR1-FLI1 translocation characteristic of Ewing sarcoma despite overt epithelial differentiation including diffuse expression of cytokeratins and p40. Most cases of ALES described to date have occurred in the head and neck where they can mimic a wide range of small round blue cell tumors. Because distinguishing ALES from basaloid salivary gland carcinomas can be particularly difficult, we analyzed a series of 10 ALESs that occurred in the salivary glands with the aim of identifying features that allow for better recognition of this entity.
