Primordial Cyst
An outdated term formerly applied to an odontogenic keratocyst that develops in place of a tooth, before any calcified dental tissue is formed.
Full Definition
The primordial cyst was historically used to describe an odontogenic cyst arising from the degeneration of the stellate reticulum of the enamel organ prior to the formation of any hard dental tissue. Contemporary classification has retired this term, with most such lesions now recognised as odontogenic keratocysts (OKC). Editors encountering 'primordial cyst' in older literature or submitted manuscripts should flag it as an obsolete term and recommend replacement with the current WHO-preferred nomenclature. Retention of the term without qualification is considered a terminology error in modern oral pathology manuscripts.
Usage
Usage note: Flag as obsolete in any contemporary manuscript. Do not use without a parenthetical explanation or historical qualifier.
