A rare case of ameloblastoma arising from radicular cyst in mandible

Background: A benign odontogenic tumour that frequently affects the jaw is ameloblastoma. There are only a small number of variations whose biological profile is not elicited, aside from the most often observed clinicopathologic models. When a cystic lesion exhibits the clinical, radiological, or physical characteristics of a mandibular cyst, it is referred to as a unicystic ameloblastoma. However, a histologic investigation reveals a typical ameloblastomatous epithelium lining the cyst cavity, with or without luminal and or mural tumour development.

Purpose: The purpose of writing this article is to describe a rare case of ameloblastoma arising from radicular cyst in mandible.

Case: A 33 year old man presented a lump in his right posterior mandible. Panoramic radiography and CT Scan image revealed a mass involving his right mandibular. The results of an incisional biopsy lead to radicular cyst. Decompression of cyst was performed, after 2 years, there was a slight shrinkage of the tumor and the results second biopsy showed an ameloblastoma.

Case management: En-bloc resection and reconstruction were performed on the patient. Following the final procedure, healing went smoothly, and the patient is currently two years into a postoperative phase during which there have been no recurrences.

Conclusion: The most frequent epithelial odontogenic tumour is the ameloblastoma, however it only accounts for 1% of all jaw tumours and cysts. It is still debatable whether or not the ameloblastoma develops from the radicular cyst. Therefore, the most accurate method for distinguishing unicystic ameloblastoma from radicular cysts is a histological study
