continued

NEOPLASTIC

● Neoplasia**(p 23)
Chronic mucopurulent or hemorrhagic nasal discharge, often unilateral initially, but progressing to
bilateral; sneezing, stertorous respiration ± facial distortion.
● Nasopharyngeal polyp (p 30)
Chronic snuffling, stertorous respiration and dyspnea from nasal obstruction; retching or gagging
with eating, ± mucopurulent nasal discharge.
INFLAMMATION
● Secondary rhinitis associated with dental disease* (p 27)
Mild, chronic mucopurulent or hemorrhagic discharge and sneezing.
● Nasopharyngeal stenosis (p 30)
Chronic snuffling, partial nasal obstruction, retching or gagging with eating.
INFECTIOUS
Bacterial:
● Secondary bacterial rhinitis*** (p 21)
Occurs secondary to viral upper respiratory tract disease. Signs include chronic mucopurulent or
hemorrhagic nasal discharge, sneezing, stertorous respiration, occasionally nasal distortion.
Fungal:

● Cryptococcus*** (p 25)
Chronic mucopurulent or hemorrhagic nasal discharge, sneezing, stertorous respiration, distortion
over bridge of nose (Roman nose), polyp-like mass in nasal opening.
● Other fungi
Aspergillus, Penicillium, Sporothrix or other fungi are very rare causes of chronic nasal disease.
Chlamydophila felis and Mycoplasma:
● Chlamydophila felis (Chlamydophila felis psittaci) and mycoplasma (p 29)
Chronic ocular and nasal discharge, chronic conjunctivitis and sneezing.
Immune:
● Allergic rhinitis (p 31)
Acute or chronic serous or mucoid nasal discharge, which is often seasonal.
Trauma:
● Oronasal fistula or nasal fractures following trauma (p 29)
Chronic snuffling, sneezing and nasal discharge associated with cleft palate, oronasal fistula or
obstructed nasal cavity.
