Peripheral odontogenic fibroma (WHO type) of the newborn: a case report

Summary. Aim. 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. Patient. 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 × 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. Conclusion. Despite the rarity of POF in a newborn, this lesion should be included as a possible diagnosis to focal gingival growth.
