Chondrosarcoma is a rare malignant tumor occurring in the trunk and long bones. We present an extremely rare case of chondrosarcoma of the hyoid bone with clinical and pathological correlation and a literature review. We searched all cases of the hyoid chondrosarcoma in PubMed (MEDLINE) between 1990 and 2015. Eighteen cases were analyzed, including the present case. Most of them were low grade type. In 12 cases where intraoperative findings were recorded, no adhesion to the surrounding tissue was observed. Chondrosarcoma of the hyoid bone is usually low grade type, and there may be no invasion to the adjacent structures even if invasion is suspected by imaging findings...

Basaloid squamous cell carcinoma (BSCC) is a histologically distinctive variant of squamous cell carcinoma comprising basal cell carcinoma and squamous cell carcinoma. BSCC is aggressive and shows a poor prognosis because of frequent lymph node invasion and distant metastases. BSCC preferentially occurs in the cervix, thymus, and esophagus and is uncommonly found in the head and neck region. BSCC in the nasal cavity or paranasal sinus is particularly rare. Inverted papilloma is an uncommon, benign tumor with a propensity to be associated with malignancy; however, BSCC arising in an inverted papilloma has never been reported...

Cases of thermal burns of the larynx in infants and in patients with mental illness have been reported, but those in older people are rare. We report two cases of thermal burns of the larynx in older people caused by ingestion of microwave-heated food (meat and potato stew or a bean-jam filled bun). Both patients were users of full dentures. Conservative therapy was effective in one patient, while tracheotomy was performed in the other patient at the time of the initial examination. Hot food is expelled from the mouth as a reflective response, preventing thermal burns of the larynx...

OBJECTIVE: Patients with allergic rhinitis (AR) show augmented activity of nitric oxide (NO) metabolism, similar to those in bronchial asthma (BA). We hypothesized that measurements of nasal fractional exhaled NO (FeNO) could be used as an objective marker to detect the presence of AR. Our objective was to clarify the influence of nasal airflow resistance (NAR) on nasal FeNO levels through an exhalation maneuver in symptomatic AR patients. We also examined the diagnostic test validity of the mean nasal FeNO level for disease discrimination by means of a receiver operating characteristic (ROC) curve analysis...

OBJECTIVE: Hypoxia-inducible factor-1 (HIF-1) is a heterodimeric basic helix-loop-helix transcription factor composed of the HIF-1α and HIF-1β subunits. HIF-1 is a central regulator of responses to hypoxia; it enhances metastasis-related factors such as matrix metalloproteinases and vascular endothelial growth factor (VEGF). We have reported critical roles for HIF-1α in tumor microenvironments, and oncogenic properties of HIF-1α have been suggested in malignancies. Seven in absentia homologue (Siah) appeared to upregulate HIF-1 production, which prompted us to investigate the Siah association with HIF-1α expression in oral squamous cell carcinoma (OSCC)...

In order to provide a basis for meaningful exchange of information among those treating cholesteatoma, the Committee on Nomenclature of the Japan Otological Society (JOS) was appointed in 2004 to create a cholesteatoma staging system as simple as possible to use in clinical practice in Japan. Following the announcement of preliminary criteria for the staging of pars flaccida (attic) cholesteatoma in 2008, we proposed the 2010 JOS staging system for two major types of retraction pocket cholesteatoma, pars flaccida and pars tensa cholesteatoma...

Dehiscent internal carotid artery (ICA) in the middle ear is a rare condition, with conservative treatment primarily recommended. We report the case of a 63-year-old patient referred to the Ear, Nose, and Throat (ENT) ward for unbearable pulsatile tinnitus. Otoscopy revealed a normal right tympanic membrane, with pulsatile tinnitus but without hearing impairment. Based on imaging studies, including computed tomography (CT) and magnetic resonance imaging (MRI) of the temporal bone, as well as Doppler ultrasound of the internal carotid artery and sigmoid sinus, the diagnosis of ICA canal dehiscence into the tympanic cavity was established, thus excluding the diagnosis of aberrant ICA...

OBJECTIVE: As 50% of patients of head and neck squamous carcinoma (HNSCC) exhibit poor prognosis, the identification of new therapeutic targets is required. Recently, there have been several reports about the correlation between Notch1 and HNSCC, but the precise mechanism is still obscure. Therefore, in this study, we examined the involvement of Notch1 in HNSCC by using HNSCC cell lines and surgical specimens. METHODS: To investigate the role of Notch1 in HNSCC, we examined the effect of Notch inhibitor DAPT on cell growth, invasion, and tumorigenicity using five HNSCC cell lines in vitro and in vivo...
