Fibromatosis is a non-metastatic, however locally invasive tumor that may infiltrate muscle, fat, and bone. It may be fatal depending on its location. Tumors in the head and neck are particularly dangerous. These fibroblast tumors have poorly defined margins and are not encapsulated. Anaplasia and invasion of nerves and vessels are not present; mitosis is rare and there may be collagen between ...

INTRODUCTION  Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction. OBJECTIVE  To verify the correlation between nasopha...

AIM To investigate the ability of natural chymase inhibitors to modulate histamine release from human mast cells. METHODS Enzymatically dispersed cells from human lung, tonsil, and skin were challenged with anti-IgE or calcium ionophore A23187 in the absence or presence of the natural chymase inhibitors secretory leukocyte protease inhibitor (SLPI) and alpha(1)-antitrypsin, then histamine rel...

OBJECTIVE To design and validate a disease-specific health status instrument-the Tonsil and Adenoid Health Status Instrument-for use in children with tonsil and adenoid disease. DESIGN Prospective psychometric and clinimetric instrument validation in 3 stages. SETTINGS A tertiary academic pediatric specialty hospital and a tertiary academic hospital, in 2 different cities. PATIENTS/OTHER PA...

The majority of neuroendocrine tumors appear to be sporadic. Neuroendocrine carcinoma (NEC) typically arises in pancreatic, parathyroid and adrenal glands, but rarely arises in salivary glands. NEC of the tonsil is a rare type of tumor and the concurrent presentation of hepatocellular carcinoma (HCC) is considered to be more uncommon. There are few case reports of NEC of the tonsil in the liter...

Introduction The primary purpose of this review was to focus on the gross anatomy, including morphometric characteristics and arterial vasculature, of the human cerebellar tonsil. We also aimed to investigate the neurosurgical anatomy of this clinically important structure of the human brain. Discussion The cerebellar tonsil is a rounded lobule on the undersurface of each cerebellar hemisphere,...

The killer cell characteristics of ƒÁƒÂTCR-bearing T cells induced from human tonsil by streptococcus pyogenes stimulation were examined. Immunohistologic staining of tonsil showed that ƒÁƒÂ TCR-bearing T cells were mainly located in the interfollicular area connected with stratified squamous epithelium. Streptococcus pyogenes could induce the proliferation of ƒÁƒÂTCRbearing T cells from tonsil...

The expression of glucocorticoid receptor-α and -β (GR-α and GR-β) in the tonsil tissues of children with and without obstructive sleep apnea hypopnea syndrome (OSAHS) was evaluated. A total of 30 children with OSAHS who underwent tonsillectomy in the Navy General Hospital from June 2012 to June 2014 were enrolled as the experimental group, and 30 non-OSAHS children were enrolled as the control...
