Which one of the following is NOT true of Ameloblastoma –
**Question:** Which one of the following is NOT true of Ameloblastoma -
A. Ameloblastoma is a benign tumor of odontogenic epithelial cells
B. Ameloblastoma is a slow-growing tumor
C. Ameloblastoma often presents as a unilocular or multilocular radiolucency in the jaws
D. Ameloblastoma has a high potential for local invasion and bone destruction
**Correct Answer:** C. Ameloblastoma often presents as a unilocular or multilocular radiolucency in the jaws.
**Core Concept:** Ameloblastoma is a benign odontogenic tumor derived from epithelial cells of dental follicle or rests of Malassez. It is characterized by uncontrolled proliferation of odontogenic epithelial cells and can lead to local invasion and bone destruction.
**Why the Correct Answer is Right:** Ameloblastoma is a benign tumor, which means it is a non-cancerous growth that does not spread to other parts of the body. However, its aggressive local invasion and bone destruction make it a formidable challenge for the treating surgeon.
**Why Each Wrong Option is Incorrect:**
A. Ameloblastoma is true, as it is a benign tumor of odontogenic epithelial cells.
B. Ameloblastoma is true, as it is a slow-growing tumor, but its aggressive behavior makes it a challenging tumor to treat.
D. Ameloblastoma is true, as it has a high potential for local invasion and bone destruction, which is a defining feature of this tumor.
**Clinical Pearl:** Ameloblastoma is a rare, locally aggressive tumor that should be surgically excised as soon as possible to prevent complications like facial swelling, tooth mobility, and pathological fracture. The correct treatment involves enucleation, excision, or segmental resection of the affected jawbone, depending on tumor size and location.
