Ectodermal (epithelial) tumors Flashcards
What tumor? Middle age patient, posterior mandible, painless tumor that will cause cortical expansion before patient knows it’s there. It will probably be pericoronal, radiolucent, fairly well circumscribed, classically multilocular, moving teeth and resorbing roots
Ameloblastoma
What Tx for Ameloblastoma?
surgical, aggressive curettage
What recurrence for Ameloblastoma?
50%
What tumor? All ages, mandibular, midbody, lucent to mixed lucent/opaque (“driven snow”), often around unerupted teeth?
Pindborg tumor or CEOT
Calcifying Epithelial Odontogenic Tumor
What Tx for Pindborg tumor or CEOT?
Surgical
What tumor? Teens, maxilla, female, 3/4 anterior jaws, on unerupted teeth, asymptomatic, lucent (pericoronal), may contain flecks of opacity?
Adenomatoid Odontogenic Tumor (AOT)
What Tx for AOT Adenomatoid Odontogenic Tumor?
enucleation (removal with cutting into tumor)
What tumor? Lucency around tooth roots, Radiographically islands of well-differentiated squamous epithelium with a peripheral layer of flattened cells.
Squamous Odontogenic Tumor (SOT)
What Tx for SOT Squamous Odontogenic Tumor?
Curettage (scrapping or scooping)
