nasal polyps
diagnoses

definition and etiology

definition: Polyps formed by nasal mucosa.

etiology: Polyp formation usually follows the edema and inflammation of a chronic allergic rhinitis, or comes from an acute or chronic sinusitis. If from an acute infection, they may regress once the infection has cleared. They are mostly found around the ostia of the maxillary sinuses, and when mature, resemble a peeled seedless grape.

signs and symptoms

• Possible obstruction of the airway.
• Recurrent sinusitis.
• Patient history of allergic rhinitis.
• Observation of polyp.

lab findings:
• eosinophilia may be present

course and prognosis

Polyps removed by corticosteroids or surgery usually recur unless the underlying reason for their presence is identified and removed (e.g. allergies).

differential diagnosis

• Foreign body.
