BACKGROUND: Odontomas are currently classified as benign mixed epithelial/mesenchymal odontogenic neoplasms which are located within the tooth-bearing regions of the jaws. Despite being considered neoplasms, the clinical characteristics of these lesions are much the same as hamartomatous lesions. Peripheral odontomas are rare entities that are located entirely within the adjacent soft tissue of the mucosa and/or gingiva. Apart from location, peripheral odontomas are morphologically, radiologically and pathologically indistinguishable from their intraosseous counterparts. CASE REPORT: An 18-year-old female patient presented with an "irritation" on the mucosa of her hard palate posterior to the maxillary incisor teeth. She reported a small, tooth-like growth in the area which had been the same size for several years. Furthermore, she was asymptomatic with no other dental concerns and, in addition, she did not have any aesthetic or functional problems. Clinical examination revealed multiple tooth-like structures which had erupted as a mass posterior to tooth 11 and tooth 12. Radiographic examination confirmed the presence of a single, oval, well-circumscribed lesion partially encapsulated and superimposed over the mid aspects of the roots and partially over the crowns of the maxillary incisor teeth. The features noted are consistent with those of a peripheral compound odontoma. CONCLUSION: Peripheral odontomas are exceedingly rare lesions which bear a resemblance and origin to their central intra-osseous counterparts. This case demonstrates a peripheral compound odontoma which had not disrupted or affected the adjacent dentition.
