Laryngeal Papilloma


Presentation

  • RESULTS: In Leeds seven cases presented to the specialist centre over the past 12 years, the average age at presentation was 6.8 years and duration of onset of symptoms to specialist review was 21 months.[ncbi.nlm.nih.gov]
  • At initial presentation, his lungs were normal with no wheezing or stridor. Soft tissue neck X-ray films suggested the presence of a subglottic mass. A large solitary papilloma was found on bronchoscopy.[ncbi.nlm.nih.gov]
  • Thus, at present, control of the disease has been successful. A combination of several modes of treatment may be necessary for a more lasting therapeutic effect. Currently, no single method has been used to treat the disease.[ncbi.nlm.nih.gov]
  • Atypia may be present but is difficult to interpret owing to the basically benign character of the lesion.[ncbi.nlm.nih.gov]
  • According to the present nomenclature, laryngeal papilloma virus therefore represents a different type of human papilloma virus and is tentatively designated as human papilloma virus type 11.[ncbi.nlm.nih.gov]
Soft Tissue Mass
  • Soft tissue lateral view of the neck demonstrates a smooth, rounded soft tissue mass arising from the posterior wall of the trachea at the level of the larynx (white arrows).[learningradiology.com]
  • Neck tissue radiograph ( fig. ) showed a soft tissue mass within the subglottic airway/larynx. Bedside flexible bronchoscopy revealed a vocal cord papilloma intermittently obstructing the airway.[anesthesiology.pubs.asahq.org]
Loss of Hair
  • Since the growth of normal body cells will also be affected, side-effects may also occur (blood, liver, or kidney problems, diarrhea, loss of hair, others).[ucdvoice.org]
Recurrent Upper Respiratory Infections
  • upper respiratory infections can be diagnosed. [4] [5] The risk of laryngeal papillomatosis spreading to the lungs is higher in the juvenile-onset than the adult-onset. [3] In children, symptoms are usually more severe and often mistaken for manifestations[en.wikipedia.org]
Feeding Difficulties
  • The symptoms, which usually appear around the ages of two to three years, include a weak cry, feeding difficulties, noisy breathing and a chronic (long-term) cough. The noisy breathing may sound like a whistle, snore or wheeze.[gosh.nhs.uk]
Camping
  • Transcription factor AP-2 mediates induction by two different signal-transduction pathways: protein kinase C and cAMP. Cell, 51: 251-260, 1987. 78. Philippe, JM., Renaud, F., Desset, S., Laurent, M., Mallet, J., Courtois, Y., and Edwards, JB.[books.google.com]
Peripheral Neuropathy
  • The clinical picture was consistent with an upper motor neuron lesion; no evidence of peripheral neuropathy was found.[ncbi.nlm.nih.gov]
Perseveration
  • The injection therapy regimen requires perseverance from both patient and surgeon. Remission of disease can be achieved in adults with laryngeal papilloma.[ncbi.nlm.nih.gov]

Clumsiness
  • When you get home Owing to the anaesthetic, your child may feel tired and a little clumsy for around 24 hours after the operation, so do not let him or her do anything that may lead to a fall.[gosh.nhs.uk]

Workup

  • Workup resulted in a diagnosis of multiple laryngeal papillomas [Figure 1]. Breathlessness in laryngeal papillomas is because of air flow obstruction due to structural interference.[ijmpo.org]
  • Clinical Testing and Workup An indirect laryngoscopy involves holding a small mirror in the back of the throat. An ENT physician will reflect light off the mirror to illuminate the throat and detect the presence of papillomas.[rarediseases.org]

Treatment

  • The therapeutic results obtained from the treatment of juvenile laryngeal papillomas with combined laser surgery and alpha-type IFN treatment are reported.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Intralesional injection of cidofovir is an excellent treatment option with limited local and systemic toxicities. The injection therapy regimen requires perseverance from both patient and surgeon.[ncbi.nlm.nih.gov]
  • To demonstrate the successful treatment of laryngeal papillomatosis in a 32-month-old girl, using coblation (radio-frequency ablation) resection.[ncbi.nlm.nih.gov]
  • In 8 patients where complete remission has been achieved, the mean number of laser treatments was 5.3.[ncbi.nlm.nih.gov]
  • There may also be a role for selective COX-2 inhibition for the treatment of[ncbi.nlm.nih.gov]

Prognosis

  • […] that are being tried include Interferon Photodynamic therapy Indol-3-carbinol Ribavirin Acyclovir Methotrexate Mumps vaccine Cidofovir It is hoped that widespread use of anti-HPV vaccines (Gardisil) will eventually lead to eradication of the disease Prognosis[learningradiology.com]

  • Treatment and prognosis Although respiratory papillomas tends to be slow growing, treatment is usually ineffective with high recurrence rate ( 90%).[radiopaedia.org]
  • In 3-5% of patients, respiratory papillomas may undergo malignant degeneration to squamous cell carcinoma, and the prognosis for patients with these cancers is quite poor. See Squamous Cell Carcinoma for more information on this topic.[emedicine.medscape.com]

Etiology

  • Testing the biopsied tissue for HPV provides further evidence of the etiology of the lesion, and viral typing can be useful. Management of laryngeal papillomas commonly involves surgery, adjuvant therapy to eliminate viral replication, and vaccines.[questia.com]
  • ETIOLOGY Although Bonjour 1 only thirteen years ago characterized the "theory of the contagiousness of warts" (and condylomata acuminata) as an error, their infectious character must be considered as proved.[jamanetwork.com]
  • The plantar wart is probably of the same etiology, although this relationship has not been demonstrated experimentally.[jamanetwork.com]

Epidemiology

  • A detailed epidemiologic questionnaire was administered at the initial visit. After enrollment, tissue obtained during each laryngeal surgery was examined by polymerase chain reaction assay for human papilloma virus (HPV) and typing.[ncbi.nlm.nih.gov]

  • (managed by the Centers for Disease Control), there is still a lack of a comprehensive epidemiological database of RRP patient information. Hence, it is difficult to determine incidence and prevalence statistics with a high degree of confidence.[rrpf.org]
  • Epidemiology: Recurrent respiratory papillomatosis may have its clinical onset either during childhood or adulthood. Juvenile onset respiratory papilloma is more aggressive, and adult onset disease may be little bit less aggressive.[drtbalu.co.in]

Pathophysiology

  • Pathophysiology HPV, the virus associated with cutaneous warts, genital condyloma, and cervical cancer, causes RRP. While more than 20 types of HPV can cause genital warts, only 2 of these, HPV-6 and HPV-11, cause the vast majority of cases of RRP.[emedicine.medscape.com]

Prevention

  • The data demonstrated a single subtype of HPV to have persisted, and the prevention of a recurrence of laryngeal papilloma during our patient's long clinical course to have failed, in spite of the interferon treatment.[ncbi.nlm.nih.gov]
  • Vaccination before becoming sexually active is the most effective way to prevent the spread of the infection. HPV vaccination can help to prevent a new HPV infection but it cannot help in anyway if the individual is already infected with the virus.[medindia.net]
  • Eventually, research may help to develop new vaccine strategies to treat or prevent RRP.[nidcd.nih.gov]
  • No treatment option has been shown to eliminate laryngeal papillomas and prevent their recurrence effectively. The most effective and commonly used treatment is surgical excision of the papilloma.[questia.com]
  • Because the child will be attempting to vocalize with a compromised mechanism during this time, it is very important that we try to prevent the child from developing any poor compensatory hyperfunctioning vocal habits.[speechpathology.com]
