Summary
Ameloblastic carcinoma, an aggressive tumor, rarely originates from the anterior skull base. This case highlights a unique presentation and invasion into the dura mater.
Area of Science:
- Oncology
- Oral and Maxillofacial Surgery
- Pathology
Background:
- Ameloblastic carcinoma (AC) is a rare and aggressive malignant epithelial odontogenic tumor.
- AC can arise de novo or from pre-existing ameloblastoma or odontogenic cysts.
- Odontogenic tumors rarely involve the skull base.
Observation:
- This report details a unique case of AC originating from the anterior skull base.
- The tumor demonstrated invasion into the dura of the anterior cranial fossa.
- This represents the first reported instance of AC in this anatomical location in English literature.
Findings:
- The anterior skull base is an exceptionally rare site for ameloblastic carcinoma.
- Invasion into adjacent structures like the dura mater signifies advanced disease.
- Clinical course and treatment strategies for skull base AC require careful consideration.
Implications:
- This case expands the known anatomical distribution of ameloblastic carcinoma.
- It underscores the importance of considering rare origins for skull base tumors.
- Further research is needed to understand the behavior and optimal management of AC in this location.

Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
