BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a low-grade soft tissue sarcoma. In the pediatric population, DFSP is exceedingly rare. Aim of this study was to describe the epidemiology and clinical outcomes in a large pediatric cohort. METHODS: Surveillance, Epidemiology, and End Results (SEER) database (1973-2010) was analyzed for all patients with dermatofibrosarcoma occurring in patients <20 years of age. Data were extracted based on age, gender, race, anatomic site, histology, stage, treatment modalities, and survival...

BACKGROUND: Facial nerve damage during head and neck surgery has long been an important issue. However, few publications on the gross anatomy of the facial nerve are available in the young population. The aim of this study was to provide in vivo measurements of the facial nerve trunk during lymphatic malformation (LM) resection and to determine the association between the trunk width and patient- and disease-related variables. METHODS: We conducted a retrospective analysis of 11 consecutive pediatric patients (11 facial nerve trunks) who underwent cervicofacial LM resection...

Neck masses in children can be inflammatory, congenital or neoplastic. When a congenital cyst becomes infected repeatedly, it may mimic inflammatory disease and the diagnosis may be challenging with ultrasound. An increasing incidence of infection with non-tuberculous mycobacterial organisms has been observed in recent decades in children with cervical lymphadenopathy. An ultrasound scan performed during the infectious phase of a mass can be misleading and can lead to an incorrect diagnostic hypothesis with the risk of erroneous medical and surgical therapies...

OBJECTIVE: Patients presenting with cystic lesions in the neck without obvious signs of malignancy constitute a diagnostic challenge since fine needle aspiration is often insufficient and a diagnosis may not be reached until surgical resection/biopsy is performed. The differential diagnosis of a cystic cervical mass comprises a variety of benign conditions, but malignancy must be ruled out. We examined the diagnostic performance of fluorine-18 fluorodeoxyglucose ((18)F-FDG) PET/CT to identify malignancy...

We present the case of a 52-year-old woman who presented to the emergency department with chest and neck pain. Initial cervical spine magnetic resonance imaging shows an abnormal flow void in the left vertebral artery, which prompted a computed tomographic angiogram. This demonstrated a hyperdense thickened ascending aortic wall, which extended into the great vessel origins. Clinically and radiographically interpreted as an acute aortic syndrome and/or intramural hematoma, the patient underwent ascending aortic repair with graft...

BACKGROUND/AIM: Many patients with recurrent head-and-neck cancer have poor outcomes. Predictive factors allowing judgment of the patient's prognosis are important for treatment individualization. This study aimed to identify such factors after irradiation of locoregional recurrence. PATIENTS AND METHODS: In 60 patients irradiated for locoregionally recurrent head-and-neck cancer, 12 factors were evaluated regarding freedom from second locoregional recurrence and survival, namely gender, tumor site, initial tumor stage, primary treatment, time between cancer diagnosis and irradiation of locoregional recurrence, age, performance score, tumor and nodal category of recurrence, upfront surgery, radiation dose and concurrent chemotherapy...

The incidence of squamous cell carcinoma (SCC) of the tongue accounts for 90% of all malignancies affecting the oral cavity and oropharynx. The distribution between the anterior and posterior tongue is equal. Nodal metastasis is dependent on various factors including tumour thickness, site, size, differentiation, and perineural and perivascular invasion. There is increasing evidence of a close correlation between tumour thickness and metastasis. A retrospective study covering the 16-year period from 2000 to 2016 was performed...

Importance: Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) has a favorable prognosis, and p16 immunohistochemistry is a surrogate marker of high-risk HPV infection and strong prognosticator. Given this favorable prognosis, treatment de-escalation for p16-positive OPSCC is now being considered with the goal of decreasing treatment-associated morbidity without compromising tumor control. The role of adjuvant chemotherapy in this setting is becoming increasingly unclear...

INTRODUCTION: HPV positive patients suffering from head and neck cancer benefit from intensified radiotherapy when applied as a primary as well as an adjuvant treatment strategy. However, HPV negative patients treated with surgery and adjuvant radiotherapy lack validated prognostic biomarkers. It is therefore important to define prognostic biomarkers in this particular patient population. Especially, ´high-risk groups´ need to be defined in order to adapt treatment protocols. Since dysregulation of the sonic hedgehog pathway plays an important role in carcinogenesis, we aimed to assess whether members of the sonic hedgehog-signaling pathway may act as prognostic factors in patients with HPV negative head and neck squamous cell carcinoma...

OBJECTIVES Lymphoma often presents with a neck mass and while fine-needle aspiration cytology may be suggestive, tissue biopsy is required for reliable diagnosis and classification of a lymphoma that is sufficient to deliver the correct treatment for the patient. Traditionally, excisional biopsy of a lymph node has been the standard method of tissue sampling, providing ample tissue for assessment. However, this requires theatre time, and preceding fine-needle aspiration cytology, which may incur a delay. With careful use of tissue, coupled with advances in immunohistochemical and molecular investigative techniques, core biopsy provides a possible alternative to traditional fine-needle aspiration and excisional biopsy...

INTRODUCTION In 2013 all UK surgical specialties, with the exception of head and neck surgery, published outcome data adjusted for case mix for indicator operations. This paper reports a pilot study to validate a previously published risk adjustment score on patients from separate UK cancer centres. METHODS A case note audit was performed of 1,075 patients undergoing 1,218 operations for head and neck squamous cell carcinoma under general anaesthesia in 4 surgical centres. A logistic regression equation predicting for all complications, previously validated internally at sites A-C, was tested on a fourth external validation sample (site D, 172 operations) using receiver operating characteristic curves, Hosmer-Lemeshow goodness of fit analysis and Brier scores...

BACKGROUND: Due to the adverse effects of cemented hip arthroplasty, uncemented stems with hydroxyapatite (HA) coating reduces these risks and enhanced integration. The concept of an extensive HA coating for the fixation of a tapered femoral stem (Corail(®)) was introduced, which can achieve durable biological fixation and preserve normal periprosthetic bone activity. Here we describe the clinical and radiological outcome in patients with the Corail(®) stem. METHODS: 92 total hip replacements in 81 patients using the Corail(®) stem were followed-up...

OBJECTIVE: The best management of carotid artery dissection (CAD) is still controversial ranging from antiplatelet medication to open surgery or endovascular treatment. In this retrospective study we assessed the safety and efficacy of endovascular stent angioplasty for the treatment of CAD. METHODS: From February 2006 to February 2016, 44 patients (28 females and 16 males, age range 25-65 years, mean 42) with CAD were included in this study. The internal carotid artery (ICA) dissection was spontaneous in origin in 32 patients and post-traumatic in the remaining 12 (1 case it was bilateral)...

OBJECTIVE: The fatty tissue regenerative properties have already been used to correct secondary scars (mastectomy, HIV lipodystrophy), resulting in improved elasticity and tissue quality. However there has been limited experience in treating the sequela of head and neck cancer treatment using fat tissue grafting. The objective of this study was to perform a preliminary evaluation of the injection of autologous fat (IAF) technique, for the sequelae treatment in head and neck cancer patients...

BACKGROUND: Early oral squamous cell carcinoma (EOSCC) represents about 90% of the oral cancers especially in older males. The etiology is multifactorial, strongly related to tobacco and alcohol abuse, but also infective agents, Human papillomaviruses (HPV16-18), genetic factors and pre-neoplastic lesions seem to be implicated. There is no consensus in the literature for the treatment of early squamous cell carcinoma of the tongue (stages I-II); both an elective neck dissection policy and a watchful-waiting policy have their proponents in the different centers...

Oral and Maxillofacial Surgery (OMFS) remains an enigmatic specialty in Irish medicine and many students are unaware of its scope and the unique career pathway involved. We performed a multicentre cross-sectional study to identify their ability to identify the requirements for entry to specialty training year 3 (ST3) in OMFS, to assess their awareness of OMFS surgeons, and their general awareness of, and exposure to, the specialty. Data were collected through an electronic questionnaire. Participants were asked to select the most suitable surgical specialty to treat a number of common conditions in the head and neck, and to choose the requirements they deemed essential for specialist training...
