Case report A 6‐year‐old speyed female Bull Arab‐cross dog was found to have a small tonsillar nodule. Histological examination revealed a well‐differentiated mast cell tumour (MCT). At initial staging, no evidence of concurrent cutaneous or visceral MCTs was found on a complete blood count, a single lateral thoracic radiograph, abdominal ultrasound or cytology of the spleen and regional lymph nodes. A diagnosis of primary tonsillar MCT was made. At 40 months postoperatively, the dog is alive with no evidence of gross tumour progression, in contrast to some previous reports of rapid disease progression and metastasis in dogs with primary oral MCTs. Conclusion To the authors’ knowledge, no previous reports of a primary MCT of the tonsil in dogs exist in the veterinary literature.
