ABSTRACT
A 3-year-old, female spayed, Pug-cross dog presented with a 2-year history of nasal congestion and focal facial deformity. Complete surgical excision was elected following nasopharyngoscopy, endoscopic biopsy and subsequent computed tomography (CT) scan. Nasopharyngoscopy revealed a friable, polypoid mass of the right nasal conchae occluding the right nasal passage. Biopsies of the mass showed expansion of the submucosa by dense bundles of well-differentiated smooth muscle cells that were strongly immunoreactive for ⍺-smooth muscle actin and desmin. Post-procedure CT revealed a large space-occupying mass in the nasal cavity with minimal lysis of the adjacent calvarium. Histology following complete excision confirmed the results obtained on the initial endoscopic biopsy. The final diagnosis was smooth muscle hamartoma.
