Masses of the Nose, Nasal Cavity; sinonasal tumors

Definition: A wide range of masses develop in the nose, nasal cavity, and nasopharynx in children. These lesions may arise from the nasal ala or other structures of the nose, including the mucosa covering any surface of the nasal cavity, the cartilaginous or osseous portion of the nasal septum, the nasal turbinates, and the nasal bones.

Lesions may also arise from the nasopharynx or adjacent structures and involve the nose by way of direct extension.

The causes of nasal masses in children include :
- congenital and developmental disorders such as congenital nasolacrimal duct mucocele, dermoid cyst, cephalocele, and nasal neuroglial heterotopia;
- inflammatory and infectious processes such as mucocele, polyp, and pyogenic granuloma;
- benign neoplasms such as infantile hemangioma and juvenile nasopharyngeal angiofibroma;
- malignant lesions such as rhabdomyosarcoma and nasopharyngeal carcinoma;
- masses related to prior trauma such as septal hematoma.
