Contributor(s):

Introduction

  • 1-2% of all canine tumors.
  • Cause: carcinomas, sarcomas, rarely polyps.
  • Primarily older dolichocephalic dogs.
  • Signs: nasal discharge, epistaxis, sneezing.
  • Diagnosis: radiography, rhinoscopy and biopsy.
  • Treatment: radiotherapy +/- chemotherapy/surgery.
  • Prognosis: depends on nature and location of tumor.

Pathogenesis

Etiology

Predisposing factors

General

  • Age.
  • Dolichocephalic breeds.

Pathophysiology

  • Nasal cavity neoplasia → unilateral nasal discharge, sneezing, epistaxis → destruction of nasal septum → bilateral discharge → expansion → nasal stertor, gagging, coughing.
  • Further local invasion (may) → facial deformity, interference with lacrimal secretions.

Timecourse

  • Chronic progression usually over months.
