Summary
Unicystic ameloblastoma (UA) is often misdiagnosed as solid ameloblastoma (SA), but distinct clinical and microscopic features allow accurate differentiation for improved surgical and prognostic outcomes. UA was more frequent and less recurrent than SA.
Area of Science:
- Oral Pathology
- Odontogenic Tumours
- WHO Classification
Background:
- Ameloblastomas are the most common odontogenic tumours.
- Accurate classification is crucial for patient management.
- The 2005 WHO Classification provides updated diagnostic criteria.
Purpose of the Study:
- To classify 163 ameloblastoma cases using the WHO Classification (2005).
- To analyze the clinical and microscopic features of ameloblastomas.
- To differentiate between solid ameloblastoma (SA) and unicystic ameloblastoma (UA).
Main Methods:
- Retrospective analysis of 163 ameloblastoma cases.
- Data collected from nine Latin-American institutions.
- Evaluation of clinico-pathological features.
Main Results:
- Ameloblastomas constitute 22.7% of odontogenic tumours.
- Unicystic ameloblastoma (UA) was twice as frequent as solid ameloblastoma (SA).
- Mean age for SA was 41.4 years, for UA was 26.3 years; mandible was the primary site for both; recurrence rates were 21.7% for SA and 12.6% for UA.
Conclusions:
- UA is frequently misdiagnosed as SA.
- Distinct clinical and microscopic features aid accurate differentiation of UA and SA.
- Recognizing these differences is vital for surgical and prognostic purposes.

02:56Treatment Resistent Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
