Sometimes, bacteria (usually streptococci and staphylococci) that infect the throat can spread deeper into the surrounding tissues. This condition is called cellulitis. If the bacteria grow unchecked, a collection of pus (abscess) may form. Abscesses may form next to the tonsils (peritonsillar) or in the side of the throat (parapharyngeal). A parapharyngeal abscess is more extensive and more dangerous than a peritonsillar abscess.Tonsillar cellulitis and tonsillar abscesses are most common among adolescents and young adults. Overall HPV prevalence in France was 57% in tonsil cancers. Mean age of diagnosis was comparable in HPV positive tonsils cases (60 ± 11.2) and HPV negative tonsil cases (59 ± 9.6). HPV prevalence was significantly higher in female than in male cases (28/35 versus 78/150 in tonsil cases, respectively, P = 0.003). Among HPV positive samples, HPV 16 was found in 89% of tonsil cases. All other HPV types had prevalence below 5%.
A doctor makes the diagnosis by viewing the throat. Tests are not usually performed, but if the doctor is not sure whether an abscess is present, computed tomography (CT) or ultrasonography can be used to identify one. Sometimes if an abscess is suspected, the doctor inserts a needle into the area and tries to draw out pus. New techniques introduced to reduce complications, making Tonsil cancer a safer operation for more people than ever before. Further research is being conducted to determine the best surveillance interval to monitor these cysts.
