ameloblastoma
TRANSCRIPT
A CASE REPORT ON AMELOBLASTOMA
INTRODUCTION True neoplasm of odontogenic epithelium Term “ Ameloblastoma” coined by Churchill –
1934. “Unicentric, nonfunctional, intermittent in
growth, anatomically benign, clinically persistent”.
2nd most common odontogenic neoplasm, & represents 1% of all oral odontogenic epithelial tumors & 11% of all odontogenic tumors.
CASE REPORT
60 year old female c/o swelling on right cheek since 2 years.
Extra orally; 1 year back
Swelling 1 year back
Present size
Intra oral swelling
1 year back
Present oral swelling
Provisional diagnosis –
AMELOBLASTOMA Differential diagnosis –
1) Odontogenic Keratocyst
2) Central giant cell granuloma
3) CEOT
4) Odontogenic myxoma
5) COC
INVESTIGATIONS Radiological – OPG, lateral occlusal
mandibular radiograph Complete blood picture, CT, BT Incisional biopsy
Present radiograph
1 year back
Bicortical expansion
Differential diagnosis –
1) central giant cell granuloma
2) odontogenic Keratocyst
3) odontogenic myxoma
4) ossifying fibroma
central giant cell granuloma
Odontogenic Keratocyst
Right body and ramus of the mandible

Odontogenic myxoma
DISCUSSION
Etiology – Varied origin cell rests of enamel organ Epithelium of odontogenic cysts Disturbances of developing enamel organ Basal cells of surface epithelium of the
jaws Heterotopic epithelium in other parts of the
body
CLINICAL FEATURES Wide age range, but uncommon in
children and adults < 20 yrs of age Posterior mandible Asymptomatic, often discovered on
routine radiographs As tumor grows, painless enlargement
may be noted
RADIOLOGICAL FEATURES Unilocular radiolucency, especially early
lesions that often progress to multilocular (soap-bubble, honeycomb)
May be associated with impacted tooth Cortical expansion and thinning Resorption of adjacent tooth roots,
displacement of teeth can be seen
