In clinical F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) studies of the head and neck region, remarkable symmetric tonsillar FDG uptake is sometimes observed. We determined the incidence and degree of tonsillar FDG uptake and investigated the significance of tonsillar FDG uptake. Between June 1998 and August 1998, we obtained informed consent from 17 patients who were schedu...

Objective This study aimed to investigate the incidence of Actinomyces in tonsillar tissues of patients undergoing tonsillectomy and to determine the association among tonsillar volume, preoperative antibiotic use, and presence of Actinomyces in tonsil tissues. Methods In this study, 142 patients who underwent tonsillectomy in last four years were included. Of the total patients, 97 (66.9%) w...

Kaposi's sarcoma is a tumor of vascular connective tissue that has been linked to human herpesvirus 8 (HHV-8) infection. Kaposi's sarcoma of the tonsil is a rare presentation that has been described in both HIV-positive and HIV-negative patients. Here we describe a patient with enlarged tonsils revealing bilateral tonsillar Kaposi's sarcoma. The patient presented with sore throat, facial pain, ...

Correlates of virus load and characteristics of virus-producing cells in tonsillar tissue were investigated. Our results suggest that when less than 1:100 tonsillar CD4(+) T cells from individuals infected with HIV type-1 (HIV-1) contain replication competent provirus, the level of CD4(+) T cells in tonsils is comparable to that observed in uninfected individuals. Virus load at or above this le...

Choristoma is a tumor-like mass consisting of tissues foreign to the site at which they are located. We report an 18 years old male presenting with persistent tonsillitis. Histological examination demonstrated the unexpected presence of a mature island of hyaline cartilage surrounded by lymphoid hyperplasia.

Background. We discuss a particular case of apparent palatine tonsil cancer that was then shown to be vagal schwannoma. Only a few cases of palatine schwannoma have been discussed in the international literature. This case is the first in which a vagal schwannoma manifested itself as a palatine tonsil cancer. Case report. A 75-year-old man reported persistent dysphonia associated with dyspnea i...

The optimal site for the isolation of beta-hemolytic streptococci (BHS) from throat cultures was investigated in 164 healthy elementary school children. All throat cultures were streaked onto duplicate blood agar plates (BAP), one of which was taken from the tonsillar fossae and the other from the posterior pharynx. BHS were isolated in cultures from 56 (34.2%) of the children. BHS were more fr...

The Moraxella immunoglobulin (Ig) D-binding protein (MID) induces a strong proliferative response in human peripheral blood IgD+ B cells from adults isolated by positive selection using anti-CD19-conjugated microbeads. Here, we show that tonsillar B cells from children isolated with positive selection are unable to respond to MID stimulation. The proliferative response was very low or absent at...

Spontaneous tonsillar hemorrhage is a rare event; most of these cases have been the result of infectious tonsillitis.1 There are reported cases of spontaneous tonsillar hemorrhage in medical literature associated with bacterial infection, measles virus infection, infectious mononucleosis, peritonsillar, parapharyngeal and retropharyngeal abscesses and, less frequently, vascular malformation, an...

nineteen lymph node biopsies, 3 curetting, 15 blood samples obtained from patients with lymphadenitis and high titers of toxoplasma antibodies, and 27 tonsillar tissues removed from patients because of chronic tonsillitis were inoculated intraperitoneally into mice for isolation of toxoplasma gondii. toxoplasms were isolated from 5 lymph node biopsies, one curettage material, 2 tonsillar tissue...
