Background: The radicular cyst is considered to be an inflammatory odontogenic cyst. The radiographic findings, present a well circumscribed, round or teardrop-shaped radiolucent area. Final diagnosis should be based on histopatological examination. The objective of this paper is to report a classic case of radicular cyst located in the anterior region of maxilla. Methods: A 24 years male patient complained of gingival and palatal swelling in the region of 11, 12, 13 and 14. Radiographic examination revealed a single well circumscribed radiolucency with approximately 2 cm diameter. Results: A total enucleation of the lesion was performed. Histological examination revealed that the lesion was "radicular cyst of inflammatory origin". Conclusions: The treatment of choice is surgical removal and subsequent histological evaluation to confirm the diagnosis. Relapses are infrequent.
