IADR/AADR/CADR General Session
A total of 239 cases were retrieved from the files of the UNMC College of Dentistry oral biopsy service which had lateral periodontal cyst (LPC) as a clinical or a histological diagnosis. Of these, 178 were submitted with a clinical differential diagnosis that included LPC. Upon histological examination only 26 (11%) of those were in fact LPC. Only 21(9%) of the 51 cases diagnosed histologically met the criteria for LPC. Within those 239 cases, 120(50%) cases were inflammatory cysts, 31(13%) of the samples were determined to be keratocystic odontogenic tumors (odontogenic keratocysts). Conclusion: The LPC is frequently misdiagnosed due to its radiographic similarity to other lateral radiolucencies.
