The Actinomysec spp. are common saprophytic microorganisms which are found in the oral cavity, pharynx and palatine tonsils. The actinomycotic infections can be responsible for recurrent chronic tonsillitis. Data about presence of actinomycotic granules in tonsillar tissue and their influence clincal course are controversial in the available literarure sources. The presence study assesses the a...

Surgically removed palatine tonsils provide a conveniently accessible source of T and B lymphocytes to study the interplay between foreign pathogens and the host immune system. In this study we have characterised the distribution of human adenovirus (HAdV), Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) in purified tonsillar T and B cell-enriched fractions isolated from three patient...

This study attempted to clarify the clinicopathological and immunohistochemical findings and presence or absence of Epstein-Barr virus (EBV) in tonsillar atypical interfollicular hyperplasia (AIFH). A total of 597 consecutive specimens from tonsillectomies performed in Dokkyo University School of Medicine between 1999 and July 2013 were reexamined. Using formalin-fixed, paraffin-embedded sectio...

Recently, submandibular abscesses associated with Actinomyces denticolens have been reported in horses. The actinomycotic clumps have been observed in the tonsillar crypts. The aim of this study was to demonstrate colonisation of A denticolens in equine tonsils. Twelve equine tonsils obtained from a slaughterhouse were divided into two parts for histopathological examination and for isolation o...

Tonsillar metastatic small cell lung cancer (SCLC) is rare, while anti-Hu antibodies are frequently found in SCLC. A 66-year-old man was admitted to our hospital with painful dysesthesia and muscle weakness in the distal extremities for over 1 year, progressive dysphagia for over 1 month, and severe cough and dyspnea for over 1 week. He was diagnosed with SCLC accompanied by tonsillar metastasi...

Skeletal muscle neoplasms, in contrast to other groups of tumors, are almost malignant. The benign variant, rhabdomyoma, is distinctly rare. Rhabdomyomas can be classified generally into two types: cardiac and extracardiac. Extracardiac rhabdomyoma can be further divided into three subtypes: adult, fetal, and genital type. Adult rhabdomyoma is the most common subtype of rhabdomyoma even though ...

The purpose of this research was to elucidate the relationship between tonsillar hypertrophy and Obstructive Sleep Apnea Syndrome (OSAS) in terms of cephalometric analysis, as well as to determine factors that affect OSAS severity. 25 patients were enrolled in this study. Lateral cephalograms of the subjects were taken. Disease severity was evaluated by the Apnea Hypopnea Index (AHI). Cephalome...

Malignant melanoma is an aggressive cutaneous melanocytic neoplasia of fast spread1. Despite its diagnosis, the disease mortality still reaches high levels. Metastasis to the oral cavity of the cutaneous melanoma is rare2-5: until 2001 less than 30 cases of metastasis in the palatine tonsils had been published3. This type of dissemination is blood-born and the prognosis is deleterious. The reas...

Preclinical antemortem testing of deer (Odocoileus spp.) for chronic wasting disease (CWD) can be important for determining prevalence rates and removing infected individuals from wild populations. Because samples with high numbers of tonsillar follicles are likely to provide earlier detection of CWD than samples with fewer follicles, the method of obtaining follicular samples may be critical w...

Tonsillar metastasis from lung cancer is an extremely rare event and is usually related to metastatic spread of the neoplastic disease to other organs with poor prognosis. We present the unusual case of a 71-year-old man who developed a huge metastasis to the left palatine tonsil from a lung adenocarcinoma. The tumor was exophytic with necrotic and hemorrhagic areas, occupying a large portion o...
