Odontoameloblastoma are tumours which represent a histological combination of ameloblastoma and complex odontoma. It behaves in an invasive manner like Ameloblastoma and is more aggressive in nature. We report a new case of ameloblastic fibro-odontoma (AFO). Clinical, radiographic and histopathological features are discussed. CASe RepoRTA 5-year-old girl presented to our department with a chief complaint of swelling in the right mandibular region. Extraoral examination revealed facial asymmetry, with swelling present on the right side of the mandible measuring 3 × 4 cm [Table/ Fig-1]. The swelling was asymptomatic and covered with healthy skin with normal colour. Intraoral examination revealed a swelling of the vestibule of mouth, extending from the deciduous canine to the deciduous second molar region, covered with normal mucosa and was hard to palpation [Table/ Fig-2]. Oral inspection also revealed a full complement of deciduous teeth present along with good oral hygiene. There was no history of local trauma or infection. The OPG revealed a welldefined radiolucent lesion extending from the lower left canine to the right deciduous second molar region [Table /Fig-3]. The border of the lesion was well-circumscribed.As the clinical features alone could not show a definitive diagnosis, incisional biopsy was performed. The histopathology revealed cellular, dental papilla-like mesenchymal tissues admixed with irregu larly shaped nests of odontogenic epithelium and areas of dentin and enamel matrix. The picture was suggestive of an AFO. The lesion was surgically excised and AFO was confirmed after excision.
