Background The incidence of human papillomavirus- (HPV-) related oropharyngeal squamous cell carcinoma (OPSCC) has been rapidly increasing worldwide. HPV is reported in approximately 50% cases of OPSCC in Japan. However, there are few reports of synchronous bilateral HPV-positive tonsillar carcinoma, and, in almost all those cases, carcinoma was detected using positron emission tomography/compu...

Progressive multifocal leukoencephalopathy is a demyelinating disease of the human central nervous system that results from lytic infection of oligodendrocytes by the polyomavirus JC (JCV). Originally, JCV was thought to replicate exclusively in human glial cells, specifically oligodendrocytes. However, we have recently shown that JCV can replicate in cells of lymphoid origin such as hematopoie...

BACKGROUND AND PURPOSE IIH is a syndrome of elevated intracranial pressure without hydrocephalus, mass, or identifiable cause. Diagnosis is made by clinical presentation, intracranial pressure measurement, and supportive imaging findings. A subset of patients with IIH may have tonsillar ectopia, meeting the criteria for Chiari malformation type I but not responding to surgical decompression for...

STUDY DESIGN A prospective cohort study. OBJECTIVE The aim of this study was to compare the somatosensory-evoked potential (SEP) findings of adolescent idiopathic scoliosis (AIS) subjects of different curve severity with age- and gender-matched controls and to evaluate any correlation between the site of the SEP abnormality with cerebellar tonsillar level measured by magnetic resonance imagin...

BACKGROUND Gastroesophageal reflux is associated with numerous pathologic conditions of the upper aerodigestive tract. Gastric pepsin within reflux contributes to immunologic reactions in the tonsil. In this study, we aimed to find the relationships between pepsin and tonsillar hypertrophy. METHODS AND FINDING We explored the notion whether tonsillar hypertrophy was due to pepsin-mediated gas...

Several subsets of dendritic cells (DCs) are present in the oropharyngeal tonsillar tissues and are thought to behave as major actors in development and regulation of immunity by acting as a first line of recognition for airborne and alimentary antigens. We previously discovered in human adult tonsils infected with Epstein-Barr virus (EBV), a subset of DCs that expressed langerin/CD207, a lecti...

INTRODUCTION AND OBJECTIVES Prevalence of the lingual tonsillar hypertrophy is unknown but it is believed that its presence is associated with the difficult airway. To investigate this, indirect laryngoscopy was performed on patients in the preoperative evaluation and this pathology was diagnosed. The relationship with difficulty of viewing the larynx, intubation and ventilation, under general ...

Introduction : Tonsillar calcification or tonsil stones (tonsilloliths) are foul smelling lumps of whitish or yellowish color. They are usually asymptomatic but can be associated with halitosis and bad taste, foreign body sensation, dysphagia and odynophagia, otalgia, and neck pain. They are a common incidental imaging finding in adults, especially in computed tomography (CT). Aim of the Work :...

OBJECTIVE To analyze the immune status in situ of tonsils of patients with recurrent tonsillitis (RT) and idiopathic tonsillar hypertrophy (ITH) with the aim to discuss the indications of tonsillectomy (TE) and tonsillotomy (TT) in young children. METHODS The histological and immunohistological study of tonsillar tissue of RT and ITH in correlation with immunological parameters in peripheral ...

PURPOSE Although each Waldeyer's ring sub-site is considered an independent prognostic factor, few studies have assessed the prognosis and treatment of tonsillar lymphoma. Treatment outcomes were analyzed in patients with primary tonsillar lymphoma who were treated with chemotherapy and radiotherapy (RT). MATERIALS AND METHODS Nineteen patients with diffuse large B-cell lymphoma were evaluate...
