title: Peripheral granular cell odontogenic fibroma.
abstract: Peripheral odontogenic fibroma is a rare lesion that arises on the gingiva and can clinically mimic a variety of reactive lesions, benign neoplasms, and metastases. We describe a symptomatic lesion arising on the mandibular gingiva of a 58-year-old female with no history of trauma or dental disease in the area. An excisional biopsy showed the lesional stroma to contain numerous polyhedral granular cells with occasional interspersed islands of inactive odontogenic epithelium. We believe this to represent the fourth case of peripheral granular cell odontogenic fibroma to be reported in detail in the literature.
