A new monoclonal antibody (MAb), F99/97.6.1, that has been used to demonstrate scrapie-associated prion protein PrP(Sc) in brain and lymphoid tissues of domestic sheep with scrapie was used in an immunohistochemistry assay for diagnosis of chronic wasting disease (CWD) in mule deer (Odocoileus hemionus). The MAb F99/97.6.1 immunohistochemistry assay was evaluated in brain and tonsil tissue from...

BACKGROUND Squamous cell carcinoma (SCC) of the tonsil is the most common malignant tumour of the oropharynx. Paediatric tonsillectomy is one of the most commonly performed procedures in Otorhinolaryngology. SCC of the tonsil remnant (SCCTR) in a previously tonsillectomised patient is rare. METHODS Retrospective review of patients with SCCTR presenting to the Otorhinolaryngology, Head and Nec...

The role of such physicians as Rudolph A. Kolliker, Johann N. Czermak, Ludwig Tuerck, Friedrich E. Voltlini, Benjamin B. Loewenberg, Hubert v. Luschka in the building of the science on hypertrophy of pharyngeal tonsil are pointed out first of all. The specific significance of achievements of Wilhelm Meyer (1824-1895) of Copenhagen based on scrupulous examinations is described. In the Polish ter...

This paper gives an overview of the anatomical localization and histological characteristics of the tonsils that are present in ten conventional domestic animal species, including the sheep, goat, ox, pig, horse, dog, cat, rabbit, rat, and pigeon. Anatomical macrographs and histological images of the tonsils are shown. Six tonsils can be present in domestic animals, that is, the lingual, palati...

We describe a case of follicular dendritic cell sarcoma (FDCS) of the tonsil in a 59-year-old woman. She was successfully treated with excision of the mass and postoperative radiation therapy. According to our review of the literature, only 25 cases of extranodal FDCS in the head and neck have been previously reported, including only 10 cases that involved a tonsil. We briefly review these earl...

The role of intestinal lymphocytes and gamma interferon (IFN-gamma) production in protective immunity to Eimeria tenella infection was evaluated in two inbred strains of chickens (SC and TK) that display different patterns of susceptibility to coccidiosis. Oral inoculation of either strain with E. tenella led to parasite invasion of the intestinal cecum and cecal tonsils. Greater fecal oocyst s...

Preclinical diagnostic tests for transmissible spongiform encephalopathies have been described for mule deer (Odocoileus hemionus), using biopsy tissues of palatine tonsil, and for sheep, using lymphoid tissues from palatine tonsil, third eyelid, and rectal mucosa. The utility of examining the rectal mucosal lymphoid tissues to detect chronic wasting disease (CWD) was investigated in Rocky Moun...

OBJECTIVES The purpose is to provide detailed estimates of population-based incidences of head and neck cancers (HNCs) between 1999 and 2012 in South Korea and to evaluate trends. METHODS Data was reviewed from the Korea National Cancer Incidence Database regarding the incidence of HNCs between 1999 and 2012. Locations that were surveyed included lip, oral tongue, oral cavity, major salivary ...

We present a case of adenomyoepithlioma (AME) arising from the tonsil. AME is an uncommon tumor that typically arises in breast, but rarely found in salivary glands, lung, and skin. Its biological features have not been thoroughly characterized. Here we describe a primary AME originating from the tonsil. The pathologic changes were characterized by hypercellularity, the dominance of both epithe...
