A clinicopathologic study of ameloblastoma

Area of Science:

• Oral and Maxillofacial Pathology
• Odontogenic Tumors
• Oncology

Background:

• Ameloblastomas are common odontogenic tumors with varied clinical presentations.
• Understanding their characteristics is crucial for diagnosis and treatment.
• Previous studies have explored ameloblastoma subtypes and locations.

Purpose of the Study:

• To investigate the correlation between patient age, radiographic appearance, and histologic type of ameloblastomas.
• To analyze the characteristics of ameloblastomas in different locations, including the mandible and maxilla.
• To determine if recurrent ameloblastomas exhibit specific features.

Main Methods:

• Retrospective analysis of 104 ameloblastoma cases.
• Correlation of patient age with radiographic and histologic findings.
• Classification of ameloblastomas based on location (mandible, maxilla, peripheral) and type (follicular, plexiform).
• Evaluation of features in recurrent ameloblastomas.

Main Results:

• A significant correlation was observed between patient age and the radiographic/histologic type of mandibular ameloblastomas.
• Follicular ameloblastomas tended to present with a multilocular or 'soap bubble' radiographic appearance.
• Plexiform ameloblastomas were more often associated with a unilocular appearance.
• Recurrent ameloblastomas predominantly showed a multilocular radiographic pattern.
• Ameloblastomas in the maxilla were histologically of the follicular type.

Conclusions:

• Patient age is a relevant factor in the presentation of mandibular ameloblastomas.
• Radiographic appearance can suggest the histologic subtype of ameloblastoma.
• Multilocular appearance may indicate recurrence.
• Maxillary ameloblastomas in this cohort were consistently of the follicular type.
