Summary Tumours of the paranasal sinuses are relatively uncommon in the horse. A collision tumour occurs when 2 separate tumour types arise in close proximity to each other and encroach on one another. This report describes the presence of neoplasia comprising glandular tissue and spindle cells growing concurrently in the frontal and caudal maxillary sinus of a geriatric donkey. As far as the authors are aware, this is the first description of a possible collision tumour in an equid.
