Abstract
Gingival growths are one of the most frequently encountered lesions in the oral cavity. A plethora of lesions can be seen having similar clinical presentation, making diagnosis a dilemma. Peripheral odontogenic tumors are rare neoplasms to occur on gingiva, the most common among them being the peripheral odontogenic fibroma (POdF). The POdF is a benign, slow-growing, exophytic lesion. Although considered to have a recurrence potential after excision, the actual recurrence rate is not known due to paucity of reported cases.Presented here is a case of a rare neoplasm mimicking an inflammatory gingival lesion with review of the available literature.How to cite this articleKhot K, Deshmane S, Bagri-Manjrekar K, Khot P.

Highlights
Oral mucosa is constantly exposed to varied stimuli and, manifests a spectrum of diseases that range from developmental, reactive, and inflammatory to neoplastic.[1]
The reason for it being referred to as odontogenic gingival epithelial hamartoma in the past is a reflection of the authors placing more emphasis on the epithelial component rather than the fibroblastic component
It does not appear to be a hamartoma because hamartomas are developmental in nature, while lesions reported as hamartomas in this particular study by Baden et al[9] appeared only in 6th and 7th decades of life rather than during the development of dentition, which means that they were not hamartomas
Summary
Oral mucosa is constantly exposed to varied stimuli and, manifests a spectrum of diseases that range from developmental, reactive, and inflammatory to neoplastic.[1]. Cook regarded all pedunculated swellings from a mucosal surface as polyps, and these mostly occurred in the line of occlusion.[4] All pedunculated and sessile lesions in the gingiva were designated as “epulis,” which commonly occurred in the maxillary anterior region. These appear on the interdental papilla as a result of local irritation from calculus, caries, or irregular restoration margins. Localized reactive hyperplastic lesions of the gingiva have been classified as focal fibrous hyperplasia, PG, peripheral ossifying fibroma (POF), and PGCG. The patient was followed up for 6 months and showed no evidence of any recurrence (Fig. 5)
