====[[Focal fibrous hyperplasia]]====

−

*44% of cases.

+

−

*Dense collagenous tissue, with ulceration/superficial inflammation

−

*Dystrophic calcificaition within the fibrous connective tissue stroma (often highly cellular, with 'young stellate fibroblasts'

−

*No odontogenic epithelium seen.

−

*Occasional strands of surface epithelium growing down into the stroma.

−

*Most of these were previously diagnosed as fibromatous or ossifying epulides.

===Neoplastic===

Line 65: Line 32:

*The stroma contains neoplastic fibroblasts, with varying cellularity.

*The overlying epitheluim is normal.

====Peripheral ameloblastoma<ref name="epulides1"> </ref>====

Line 76: Line 46:

*Often infiiltrating into the underlying bone.

*Synonymous with basal cell carcinoma.

====Central ameloblastoma<ref name="epulides1"> </ref>====

*Different from peripheral ameloblastoma - cystic changes and follicular arrangement of ameloblasts and stellate reticulum cells, resembling the basic structure of the [[Tooth Anatomy - Anatomy & Physiology|enamel organ]].
