Peripheral odontogenic fibroma (POdF) is a relatively rare benign tumor that originates in the peripheral gingiva. Only a few cases of POdF in infants have been reported. In this paper, we report a case of POdF arising bilaterally in the mandibular gingiva of an infant.
A 3-year-old boy was referred to our clinic because of a growing mass bilaterally arising in the mandibular gingiva at the distal region of the second deciduous molar. Intraoral examination revealed a bilateral rough and irregularly surfaced gingival mass. An X-ray film showed no destruction of the mandibular bone.
The clinical diagnosis was a benign gingival tumor, and tumor extirpation was performed with the patient under general anesthesia. The extirpated masses were white and elastic hard tissue.
Histopathological examination revealed that the tumor was composed mainly of fibroblastic tissue with scattered islands of odontogenic epithelium. The definitive diagnosis was POdF.
There has been no sign of recurrence as of 2 years after surgery.
