We report a rare and unusual case of a Peripheral Ameloblastic Fibro-Dentinoma (PAFD) occurring in a 3 year old Indian boy. The boy presented to the hospital complaining of swelling in anterior maxillary region with a history of trauma. Periapical radiography of the area did not reveal any bone resorption. The entire mass was excised under local anesthesia, and the histological examination revealed a diagnosis of PAFD. The postoperative course was satisfactory and the excised area has remained free of recurrence for 9 months. PAFD is a rare entity and only 5 cases have been reported in literature. The present case is one of the youngest in the group. The mode of differentiation of the odontogenic lesion is a pointer in the diagnosis and histogenesis has been discussed.
