Laryngeal papillomatosis
Laryngeal papillomatosis, also known as recurrent respiratory papillomatosis or glottal papillomatosis or associated with condyloma acuminata, is a rare medical condition (2 per 100,000 adults and 4.5 per 100,000 children),〔(【引用サイトリンク】location= http://www.nidcd.nih.gov/health/voice/laryngeal.asp )〕 caused by an HPV infection of the throat. Laryngeal papillomatosis causes assorted tumors or papillomas to develop over a period. Without treatment it is potentially fatal as uncontrolled growths could obstruct the airway. Laryngeal papillomatosis is caused by HPV types 6 and 11, in which benign tumors form on the larynx or other areas of the respiratory tract. These tumors can recur frequently, may require repetitive surgery, and may interfere with breathing. The disease can be treated with surgery and antivirals.
==Transmission==
In general, physicians are not sure what causes certain people to develop laryngeal papillomatosis while others who have been exposed to HPV types 6 and 11 do not develop the disease. Since the disease is most commonly found in children, the disease may be caused by an infant contracting HPV from the mother during vaginal child birth.〔(【引用サイトリンク】location= http://www.voiceproblem.org/disorders/rrp/symptoms.asp )〕 There is no evidence that it is transmitted through oral sex, and it is not considered a sexually transmitted disease.〔(【引用サイトリンク】title=Recurrent Respiratory Papillomatosis )〕
