Resumo
The present case reports a rare benign tumor of a 30-year-old
female patient presenting with a painless, erythematous, sessile,
firm, localized swelling on the distal of the left mandibular pre molar of approximately 3 years’ duration. Covering mucosa was
intact and there was no bone involvement. The initial clinical
diagnosis was pyogenic granuloma. An excisional biopsy was
performed and the histopathologic examination showed a mark edly cellular connective tissue intermixed with nests and strands
of inactive-looking odontogenic epithelium. Deposition of a
mineralized material resembling dentinoid was seen. The
epithelial elements were positive for AE1/AE3 and CK14. The
histopathologic and immunohistochemical features were consis tent with a diagnosis of peripheral odontogenic fibroma, epithe lium-rich type. No recurrence was found during a 4-month
follow-up. Peripheral odontogenic fibroma is often misdiagnosed
as a reactive lesion because of similar clinical features and, thus, a
histopathologic examination is required for accurate definitive
diagnosis.
