Plain-English summary
A 3-year-old female Pug-cross was brought to the vet with a 2-year history of nasal congestion and a noticeable change in her face. After examining her nose with a scope and taking a CT scan, the vet found a mass blocking her right nasal passage. The vet performed surgery to remove the mass, which was confirmed to be a smooth muscle hamartoma, a type of benign growth. After the surgery, the dog was able to breathe better, and her facial appearance improved.

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.
