Clinical Information

  • Dentigerous Cyst

    most common follicular odontogenic cyst. occurs in relation to a partially erupted or unerupted tooth with at least the crown of the tooth to which the cyst is attached protruding into the cystic cavity. may give rise to an ameloblastoma and, in rare instances, undergo malignant transformation.
  • Ameloblastic Carcinoma Derived From Odontogenic Cyst|Ameloblastic Carcinoma Ex Odontogenic Cyst

    a rare, aggressive malignant tumor that originates from an odontogenic cyst in the maxillomandibular region. it combines the histologic features of an ameloblastoma and carcinoma.
  • Botryoid Odontogenic Cyst|BOC

    the multicystic variant of lateral periodontal cyst. (who 2017)
  • Calcifying Cystic Odontogenic Tumor|Calcifying Odontogenic Cyst|Calcifying odontogenic cyst|Gorlin Cyst

    a benign, intraosseous or extraosseous cystic neoplasm arising from tooth-forming tissues. it is characterized by the presence of a cyst lined by an ameloblastoma-like epithelium and ghost cells formation. the ghost cells may undergo calcification. it is treated with enucleation. few recurrences have been reported for intraosseous neoplasms whereas no recurrences have been reported for extraosseous neoplasms.
  • Calcifying Odontogenic Cyst|COC

    a simple odontogenic cyst lined by ameloblastoma-like epithelium, which contains focal accumulations of ghost cells. (who 2017)
  • Glandular Odontogenic Cyst|GOC

    a developmental odontogenic cyst with epithelial features that simulate salivary gland or glandular differentiation. (who 2017)
  • Odontogenic Cyst

    a cyst in the jaw that arises from tissues of tooth development.
  • Orthokeratinized Odontogenic Cyst|OOC

    an odontogenic cyst that is entirely or predominantly lined by orthokeratinized stratified squamous epithelium. (who 2017)
  • Primary Intraosseous Squamous Cell Carcinoma Derived From Odontogenic Cyst|Primary Intraosseous Carcinoma Ex Odontogenic Cyst

    a rare squamous cell carcinoma that arises centrally from the jaw from the lining of an odontogenic cyst.
  • Dentigerous Cyst

    an odontogenic cyst that is attached to the cervical region of an unerupted tooth and envelops the crown. (who 2017)

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
