A 7-month-old, male, Burmese cat was presented with an oral mass that had rapidly regrown following excisional biopsy 3 weeks earlier. The tumour was identified by histological examination as a feline inductive odontogenic tumour. A unilateral segmental mandibulectomy was performed. Although dental malocclusion resulted from mandibular drift to the operated side, the cat displayed minimal dysphagia post-operatively and there was no evidence of tumour regrowth 8 months after surgery. Feline inductive odontogenic tumour is a rare dental tumour described exclusively in cats under 3-years-of-age. Although histopathologically benign, feline inductive odontogenic tumour grows by expansion and can infiltrate underlying bone to cause considerable local destruction. This article is intended to increase awareness of this unusual tumour which, with complete surgical excision, carries a good prognosis. It also emphasises the importance of obtaining a histological diagnosis from oral mass lesions to direct appropriate therapy and to provide an accurate prognosis.
