RT Journal Article SR Electronic T1 Isolated odontogenic keratocyst JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 1392 OP 1394 VO 117 IS 12 A1 A. Gryfe A1 J. H. Gryfe YR 1977 UL http://www.cmaj.ca/content/117/12/1392.abstract AB Although odontogenic keratocysts are benign they are often locally destructive and tend to recur after conservative surgical treatment. They must therefore be distinguished from other cysts of the jaw. Keratocysts possess outpouchings and microscopic daughter cysts from which recurrences may arise. Histologic examination is essential for diagnosis since the appearances on roentgenograms and at operation usually do not reveal the true nature of the lesion. Since many nondental surgeons and pathologists are unaware of odontogenic keratocysts a case is presented in which surgical treatment was originally conservative and finally relatively radical.
