This is a benign but locally invasive odontogenic tumour that appears in the [[Gingiva|gingiva]], often surrounding and displacing the adjacent teeth. The lesions have a raised and cauliflower appearance and are slow growing. Eventually the lesions can become very large and involve the jaw bone.

Required for a definitive diagnosis and incisional biopsy is the technique of choice. When undertaking cytological or grab procedures it is more difficult to obtain a representative sample.

'''Pathology''':
 +
Islands and sheets of mature odontogenic epithelium within a collagenous fibrous connective tissue stroma of low/moderate cellularity will be noticed. Each of the islands is bounded by a row of tall columnnar cells. These palisading cells exhibit polarisation away from the basement membrane and have cytoplasmic vacuolation. Central cells have a basaloid appearance. The tumour is often infiiltrating into the underlying bone.
