Plain-English summary
A 12-year-old male neutered European Shorthair cat was brought in for itching in the right ear, bleeding from the ear canal, and a mass that looked like a polyp. After imaging and a biopsy, the mass was diagnosed as a low-grade mast cell tumor. The vet performed surgery to remove the entire ear canal, and follow-up tests showed no remaining tumor cells at the edges of the excised tissue. Unfortunately, the cat was euthanized 14 months later, but it's unclear if this was due to the tumor spreading. Mast cell tumors in the ear canal are rare but should be considered when diagnosing ear canal growths.

Abstract
A 12-year-old male neutered European Shorthair cat was presented for pruritus in the right ear region, bleeding from ear canal and a suspected polyp-like mass in its lumen.After the diagnostic imaging a biopsy of the mass was taken and submitted for histopathological evaluation. Histopathologic examination led to the diagnosis of low grade mast cell tumor. The subsequent staging examinations included ultrasonography of the liver and spleen as well as a complete blood count. Total ear canal ablation was performed on the same day, and the removed ear canal was again submitted for histopathologic evaluation of the surgical margins. The excision incision margins were free from infiltrating tumor cells. The cat was euthanised 14 months after the surgery. It is unknown whether the reasons for this were associated to metastatic spread of the initial mast cell tumor.A mast cell tumor in the ear canal is an unusual and rare finding, however it should be included in the list of differential diagnoses for ear canal tumors.
