BACKGROUND: Planar lymphoscintigraphy (PL) has a lower detection rate of sentinel lymph nodes (SLNs) in head and neck melanoma compared with other sites. We assessed situations when single-photon emission computed tomography/computed tomography (SPECT/CT) identified nodes not seen by PL. We also evaluated the impact of SPECT/CT on surgical approach and oncologic outcomes. METHODS: Patients who underwent SLN biopsy (SLNB) for head and neck melanoma with PL and SPECT/CT between November 2011 and December 2016 were included...

We would like to draw to the attention of head and neck surgeons the following disease that can present first to head and neck specialists with either a head and neck lump or following an incidental finding on radiological imaging. Familial Adenomatous Polyposis (FAP) is a hereditary disease caused by a mutation in the APC gene on chromosome 5, which is inherited in an autosomal dominant fashion with complete penetrance but variable expression(1). However in approximately 25% of cases it arises from a de novo mutation of the APC gene(1)...

Neuroendocrine carcinomas of the head and neck are rare and are classified as well differentiated, moderately differentiated, and poorly differentiated carcinomas with the latter category being subdivided into small cell and large cell neuroendocrine carcinoma (LCNEC). While most carcinomas in the nasopharynx are associated with Epstein-Barr virus (EBV), there has been only one previous report demonstrating a link between EBV and LCNEC of the nasopharynx. In this report we describe a second case of EBV-positive LCNEC arising in the nasopharynx with bilateral cervical metastases...

Background: Hemangiomas of the soft tissue are common in the head and neck area, especially in the tongue and in children under ten years of age. Intraosseous hemangiomas of the mandible and maxilla (IHM), on the other hand, are exceedingly rare and are not well characterized. This study presents six IHM cases focusing on the clinical, radiographic, and histologic characteristics. Material and Methods: Six cases of IHM were retrieved from the archives of the Biopsy Services at the University of Washington...

We report two patients with increased central skull base and craniocervical junction bone pneumatisation complicated by extra-osseous gas. One patient presented with symptoms of increasing nasal blockage and 'sinus pressure' on a background of extensive nasal polyposis. He was subsequently found to have a history of repeated Valsalva's manoeuvre, the cessation of which resulted in a rapid decrease in the amount of extra-osseous gas on imaging. The second patient presented following a minor head trauma with dysarthria from a hypoglossal nerve palsy and neck pain, with extensive intra- and extra-cranial gas including within the spinal canal (pneumorrhachis)...

OBJECTIVES: Melanotic neuroectodermal tumor of infancy (MNTI) of the head and neck is a rare entity with uncertain clinical behavior. Radical surgical resection is the current recommended treatment, however this can cause severe aesthetic and functional sequelae. The aim of this study was to clinically characterize MNTIs and to stratify risk factors that may influence locoregional recurrence. METHODS: A retrospective multicenter study, including 11 patients from eight centers with a confirmed diagnosis of MNTI, was conducted...

Mönckeberg medial calcinosis describes calcifications affecting only the tunica media of medium-sized arteries. The entity is strongly associated with chronic kidney disease and diabetes mellitus. Radiographically, medial calcinosis presents as areas of linear calcifications in soft tissue; the linear calcifications are referred to as "tram tracks," "pipe stem," "rail tracking," or "tram line" when the affected vessel is viewed longitudinally. In oral and maxillofacial radiology, it is generally an incidental finding of the facial artery...

To establish the prognostic factors for primary intraosseous squamous cell carcinoma we designed a retrospective study of patients treated in the head and neck department of a tertiary referral centre in China from 2010-2015. We collected clinical, radiological, and histopathological data from 36 patients treated during the given time period, among which 34 were followed up. There were 22 male and 12 female patients, 13 of whom gave a history of smoking tobacco and four who drank alcohol. All 34 patients were treated by segmental mandibulectomy and neck dissection...

An intraosseous lipoma is a rare histologic variant of lipoma, accounting for only 0.1% of all primary bone tumors. This may not be the actual incidence because most of these lesions are frequently asymptomatic, but imaging modalities, such as computed tomography or magnetic resonance imaging (MRI) seem to have increased the detection rate. Lipoma occasionally undergoes osseous metaplasia and becomes an osseous lipoma. Although there are numerous papers discussing intraosseous lipoma and some authors have tried to differentiate lipomas from osseous lipomas, there is still a great deal of confusion with regard to characteristic radiologic features and the use of terms...

Retained foreign bodies within the stomach and proximal small bowel may be problematic in patients with prior cerebrovascular injury or head, neck and esophageal malignancy, given the increased vulnerability of this patient population to complications from aspiration and increased difficulty of esophagogastroduodenoscopy in cases of tumoral obstruction. This article presents an alternative method for foreign body retrieval through an existing gastrostomy tract, which offers the benefits of fast procedure times, reduction in radiation dose and fluoroscopy time, and allows for safer retrieval of foreign bodies by using direct visualization...

PURPOSE: The aim of this study was to investigate the incidence of Z-effect after dual lag screw intramedullary nailing systems and risk factors contributing to this effect. We hypothesized that long nails provide more neck strength due to a longer lever than short nails and are therefore less likely to develop a misbalance of a higher head compressive strength than neck compressive strength. METHODS: In this retrospective cohort study 103 patients treated operatively with a dual lag screw intramedullary nailing device for (sub)trochanteric hip fracture were included...

REVIEW
Tristan Klosterman, Teresa M O
Vascular malformations may affect nearly all aspects of the upper airway. Each type of malformation has a characteristic pattern of disease. These lesions may be focal or diffuse, and require directed management strategies. Physicians treating these entities should have a high level of suspicion to consider airway evaluation even in the absence of overt symptoms. However, cutaneous head and neck venous malformations or other lesions affecting the lips, oral cavity, or tongue can herald the presence of coexisting airway lesions...

Paula E North
Accurate histopathologic description in correlation with clinical and radiological evaluation is required for treatment of vascular anomalies, both neoplastic and malformative. It is important to examine current clinical, histologic, and immunophenotypical features that distinguish the major types of congenital and perinatal vascular anomalies affecting the head and neck. General discussions of pathogenesis and molecular diagnosis must also be taken into account. This article provides an overview of the features that distinguish the major types of congenital and perinatal vascular anomalies affecting the head and neck, and summarizes the diagnostic histopathologic criteria and nomenclature currently applied to these lesions...

Background: Solitary fibrous tumor is an uncommon spindle cell neoplasm of unknown origin. It has been reported in many anatomic sites, with a rare occurrence in the head and neck region. Solitary fibrous tumors of the parotid gland are exceptional; their clinical and radiologic features are non specific, often mimicking more common salivary gland tumors. Pathologic examination and immunohistochemistry are required to make the correct diagnosis. The prognosis is favorable, with most tumors being benign, and complete surgical resection is the treatment of choice...
