Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a nonmalignant disease of unknown etiology. It may present as bilateral, massive, painless cervical lymphadenopathy; however, one third of the cases have extranodal involvement. Extranodal sites include soft tissue, skin, upper respiratory and gastrointestinal tracts, and central nervous system, with head and neck being the most common. Here we report a rare case of intracardiac RDD in a 46-year-old, African-American female who presented with worsening shortness of breath and fatigue for 7 weeks...

Kimura's Disease (KD) is a rare chronic inflammatory disorder presenting as multiple painless solitary subcutaneous nodules, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. Because of painless nature and indolent course, there is usually a delay in the patient's presentation. KD may radiologically mimic other chronic inflammatory conditions like tuberculosis, vascular malformations and neoplasms. Clinical correlation and histological evaluation along with elevated peripheral eosinophil and serum IgE level are considered important for confirmatory diagnosis...

INTRODUCTION: Posterior comminution of the femoral neck fracture is a major cause of delayed and non-union owing to the loss of the buttressing effect against the posterior rotation. When a femoral neck fracture with posterior comminution is anatomically reduced, only the anterior portions of the femoral neck fracture surfaces are brought into contact leaving a posterior defect. The purpose of this study was to evaluate the use of fibular strut grafting and dynamic hip screw (DHS) for fresh femoral neck fractures with posterior comminution in young patient less than 50 years...

Osteochondromas, the most common benign bone tumors, are cartilaginous neoplasms of unknown origin with rare malignant potential. Osteochondromas rarely occur in the head and neck, and diagnosis relies on a combination of clinical, radiological, and histological criteria. Excision is often curative. We describe the first reported case of hyoid osteochondroma in an adolescent male with multiple osteochondroma, discuss its surgical management, and perform a review of the salient literature. Osteochondroma represents a rare diagnosis to include in the differential of any midline neck mass...

BACKGROUND: Ultrasound-guided wire localisation is a technique that is well established in breast surgery, but is not well described in head and neck practice. It can be used to locate impalpable lesions for surgical removal, without the need for more extensive surgery. METHOD: This paper describes a case where the technique was used to assist in the removal of an impalpable but radiologically abnormal lymph node. CONCLUSION: The technique offers a safe and effective method for removing lesions within the head and neck...

Schwannoma is a benign tumor that originates from Schwann cells of the peripheral nerve. Occurring as a common tumor in the head and neck region, its intraoral presentation is rare which accounts for only 1%. They are solitary, slow-growing, smooth-surfaced, usually asymptomatic, and encapsulated tumor. This paper comprises two case reports, both of which presented with an intraoral soft tissue swelling which turned out to be schwannoma of buccal mucosa and infratemporal fossa with extension into the oral cavity, respectively...

The authors describe a case of gunshot injury in a 26-year-old male patient with an unusual bullet trajectory. The bullet had an entry hole just near the right lateral alar cartilage of the nose, and the trajectory descended through the left side of the neck by route of the hard palate, soft palate, and posterior pharyngeal wall, respectively. Surgical removal of the bullet was achieved with neck exploration. Gunshot injuries of the head and neck necessitate a thorough clinical and radiological evaluation due to the possibility of an unusual bullet trajectory...

PURPOSE: The Imaging and Radiation Oncology Core - Houston (IROC-H) Quality Assurance Center (formerly the Radiological Physics Center) has reported varying levels of compliance from their anthropomorphic phantom auditing program. IROC-H studies have suggested that one source of disagreement between institution submitted calculated doses and measurement is the accuracy of the institution's treatment planning system dose calculations and heterogeneity corrections used. In order to audit this step of the radiation therapy treatment process, an independent dose calculation tool is needed...
