Peripheral odontogenic fibroma (WHO type) of the newborn: a case report.
OBJECTIVE
The present paper reports a case of peripheral odontogenic fibroma (POF) (WHO type) in a newborn. The differential diagnosis and treatment were discussed.


BACKGROUND
POF is well described in the literature, but this is the first report in a newborn.


METHODS
A 4-month-old female newborn was referred to our department because of an exophytic, sessile, firm, and well-delimited lesion on the right upper alveolar ridge. The covering mucosa was apparently normal. The lesion measuring 10 x 3 mm was present since birth. The clinical diagnosis of congenital granular cell tumour (congenital epulis) or dental lamina cyst of the newborn was made. A conservative excisional biopsy was performed under local anaesthesia, and the specimen was submitted to histopathological examination.


RESULTS
The microscopic examination revealed a pattern of POF (WHO type). Normal primary incisors teeth eruption, and no signs of recurrence were noted on 16 months follow-up.


CONCLUSIONS
Despite the rarity of POF in a newborn, this lesion should be included as a possible diagnosis to focal gingival growth.
